Pull random number generator updates from Jason Donenfeld:
"Originally I'd planned on sending each of the vDSO getrandom()
architecture ports to their respective arch trees. But as we started
to work on this, we found lots of interesting issues in the shared
code and infrastructure, the fixes for which the various archs needed
to base their work.
So in the end, this turned into a nice collaborative effort fixing up
issues and porting to 5 new architectures -- arm64, powerpc64,
powerpc32, s390x, and loongarch64 -- with everybody pitching in and
commenting on each other's code. It was a fun development cycle.
This contains:
- Numerous fixups to the vDSO selftest infrastructure, getting it
running successfully on more platforms, and fixing bugs in it.
- Additions to the vDSO getrandom & chacha selftests. Basically every
time manual review unearthed a bug in a revision of an arch patch,
or an ambiguity, the tests were augmented.
By the time the last arch was submitted for review, s390x, v1 of
the series was essentially fine right out of the gate.
- Fixes to the the generic C implementation of vDSO getrandom, to
build and run successfully on all archs, decoupling it from
assumptions we had (unintentionally) made on x86_64 that didn't
carry through to the other architectures.
- Port of vDSO getrandom to LoongArch64, from Xi Ruoyao and acked by
Huacai Chen.
- Port of vDSO getrandom to ARM64, from Adhemerval Zanella and acked
by Will Deacon.
- Port of vDSO getrandom to PowerPC, in both 32-bit and 64-bit
varieties, from Christophe Leroy and acked by Michael Ellerman.
- Port of vDSO getrandom to S390X from Heiko Carstens, the arch
maintainer.
While it'd be natural for there to be things to fix up over the course
of the development cycle, these patches got a decent amount of review
from a fairly diverse crew of folks on the mailing lists, and, for the
most part, they've been cooking in linux-next, which has been helpful
for ironing out build issues.
In terms of architectures, I think that mostly takes care of the
important 64-bit archs with hardware still being produced and running
production loads in settings where vDSO getrandom is likely to help.
Arguably there's still RISC-V left, and we'll see for 6.13 whether
they find it useful and submit a port"

Register KVM's cpuhp and syscore callbacks when enabling virtualization in
hardware, as the sole purpose of said callbacks is to disable and re-enable
virtualization as needed.
The primary motivation for this series is to simplify dealing with enabling
virtualization for Intel's TDX, which needs to enable virtualization
when kvm-intel.ko is loaded, i.e. long before the first VM is created.
That said, this is a nice cleanup on its own. By registering the callbacks
on-demand, the callbacks themselves don't need to check kvm_usage_count,
because their very existence implies a non-zero count.
Patch 1 (re)adds a dedicated lock for kvm_usage_count. This avoids a
lock ordering issue between cpus_read_lock() and kvm_lock. The lock
ordering issue still exist in very rare cases, and will be fixed for
good by switching vm_list to an (S)RCU-protected list.

Support huge pfnmaps by using bit 56 (PTE_SPECIAL) for "special" on
pmds/puds. Provide the pmd/pud helpers to set/get special bit.
There's one more thing missing for arm64 which is the pxx_pgprot() for
pmd/pud. Add them too, which is mostly the same as the pte version by
dropping the pfn field. These helpers are essential to be used in the new
follow_pfnmap*() API to report valid pgprot_t results.
Note that arm64 doesn't yet support huge PUD yet, but it's still
straightforward to provide the pud helpers that we need altogether. Only
PMD helpers will make an immediate benefit until arm64 will support huge
PUDs first in general (e.g. in THPs).

There're:
- 8 archs (arc, arm64, include, mips, powerpc, s390, sh, x86) that
support pte_pgprot().
- 2 archs (x86, sparc) that support pmd_pgprot().
- 1 arch (x86) that support pud_pgprot().
Always define them to be used in generic code, and then we don't need to
fiddle with "#ifdef"s when doing so.

LoongArch KVM changes for v6.12
1. Revert qspinlock to test-and-set simple lock on VM.
2. Add Loongson Binary Translation extension support.
3. Add PMU support for guest.
4. Enable paravirt feature control from VMM.
5. Implement function kvm_para_has_feature().
Hook up the generic vDSO implementation to the aarch64 vDSO data page.
The _vdso_rng_data required data is placed within the _vdso_data vvar
page, by using a offset larger than the vdso_data.
The vDSO function requires a ChaCha20 implementation that does not write
to the stack, and that can do an entire ChaCha20 permutation. The one
provided uses NEON on the permute operation, with a fallback to the
syscall for chips that do not support AdvSIMD.
This also passes the vdso_test_chacha test along with
vdso_test_getrandom. The vdso_test_getrandom bench-single result on
Neoverse-N1 shows:
vdso: 25000000 times in 0.783884250 seconds
libc: 25000000 times in 8.780275399 seconds
syscall: 25000000 times in 8.786581518 seconds
A small fixup to arch/arm64/include/asm/mman.h was required to avoid
pulling kernel code into the vDSO, similar to what's already done in
arch/arm64/include/asm/rwonce.h.

Currently alternative_has_cap_unlikely() can be used in VDSO code, but
alternative_has_cap_likely() cannot as it references alt_cb_patch_nops,
which is not available when linking the VDSO. This is unfortunate as it
would be useful to have alternative_has_cap_likely() available in VDSO
code.
The use of alt_cb_patch_nops was added in commit:
d926079f17 ("arm64: alternatives: add shared NOP callback")
... as removing duplicate NOPs within the kernel Image saved areasonable
amount of space.
Given the VDSO code will have nowhere near as many alternative branches
as the main kernel image, this isn't much of a concern, and a few extra
nops isn't a massive problem.
Change alternative_has_cap_likely() to only use alt_cb_patch_nops for
the main kernel image, and allow duplicate NOPs in VDSO code.

Add all of the flags that are needed to support the shadow call stack
(SCS) sanitizer with Rust, and updates Kconfig to allow only
configurations that work.
The -Zfixed-x18 flag is required to use SCS on arm64, and requires rustc
version 1.80.0 or greater. This restriction is reflected in Kconfig.
When CONFIG_DYNAMIC_SCS is enabled, the build will be configured to
include unwind tables in the build artifacts. Dynamic SCS uses the
unwind tables at boot to find all places that need to be patched. The
-Cforce-unwind-tables=y flag ensures that unwind tables are available
for Rust code.
In non-dynamic mode, the -Zsanitizer=shadow-call-stack flag is what
enables the SCS sanitizer. Using this flag requires rustc version 1.82.0
or greater on the targets used by Rust in the kernel. This restriction
is reflected in Kconfig.
It is possible to avoid the requirement of rustc 1.80.0 by using
-Ctarget-feature=+reserve-x18 instead of -Zfixed-x18. However, this flag
emits a warning during the build, so this patch does not add support for
using it and instead requires 1.80.0 or greater.
The dependency is placed on `select HAVE_RUST` to avoid a situation
where enabling Rust silently turns off the sanitizer. Instead, turning
on the sanitizer results in Rust being disabled. We generally do not
want changes to CONFIG_RUST to result in any mitigations being changed
or turned off.
At the time of writing, rustc 1.82.0 only exists via the nightly release
channel. There is a chance that the -Zsanitizer=shadow-call-stack flag
will end up needing 1.83.0 instead, but I think it is small.

:
: From the cover letter:
:
: "Another task that a hypervisor supporting NV on arm64 has to deal with
: is to emulate the AT instruction, because we multiplex all the S1
: translations on a single set of registers, and the guest S2 is never
: truly resident on the CPU.
:
: So given that we lie about page tables, we also have to lie about

: complicated by the fact that guest S1 page tables can be swapped out,
: and that our shadow S2 is likely to be incomplete. So while using AT

* kvm-arm64/vgic-sre-traps:
: .
: Fix the multiple of cases where KVM/arm64 doesn't correctly
: handle the guest trying to use a GICv3 that isn't advertised.
:
: From the cover letter:
:
: "It recently appeared that, when running on a GICv3-equipped platform
: (which is what non-ancient arm64 HW has), *not* configuring a GICv3
: for the guest could result in less than desirable outcomes.
:
: We have multiple issues to fix:
:
: - for registers that *always* trap (the SGI registers) or that *may*
: trap (the SRE register), we need to check whether a GICv3 has been
: instantiated before acting upon the trap.
:
: - for registers that only conditionally trap, we must actively trap
: them even in the absence of a GICv3 being instantiated, and handle
: those traps accordingly.
:
: - finally, ID registers must reflect the absence of a GICv3, so that
: we are consistent.
:
: This series goes through all these requirements. The main complexity
: here is to apply a GICv3 configuration on the host in the absence of a
: GICv3 in the guest. This is pretty hackish, but I don't have a much
: better solution so far.
:
: As part of making wider use of of the trap bits, we fully define the

Since SPSR_* are not associated with any register in the sysreg array,
nor do they have .get_user()/.set_user() helpers, they are invisible to
userspace with that encoding.
Therefore hidden_user_visibility() serves no purpose here, and can be
safely removed.

We go trough a great deal of effort to map CNTKCTL_EL12 to CNTKCTL_EL1
while hidding this mapping from userspace via a special visibility helper.
However, it would be far simpler to just provide an accessor doing the
mapping job, removing the need for a visibility helper.
With that done, we can also remove the EL12_REG() macro which serves
no purpose.

While arch/*/mem/ptdump handles the kernel pagetable dumping code,
introduce KVM/ptdump to show the guest stage-2 pagetables. The
separation is necessary because most of the definitions from the
stage-2 pagetable reside in the KVM path and we will be invoking
functionality specific to KVM. Introduce the PTDUMP_STAGE2_DEBUGFS config.
When a guest is created, register a new file entry under the guest
debugfs dir which allows userspace to show the contents of the guest
stage-2 pagetables when accessed.

Rename the attributes description array to allow the parsing method
to use the description from a local context. To be able to do this,
store a pointer to the description array in the state structure. This
will allow for the later introduced callers (stage_2 ptdump) to specify
their own page table description format to the ptdump parser.

When we share memory through FF-A and the description of the buffers
exceeds the size of the mapped buffer, the fragmentation API is used.
The fragmentation API allows specifying chunks of descriptors in subsequent
FF-A fragment calls and no upper limit has been established for this.
The entire memory region transferred is identified by a handle which can be
used to reclaim the transferred memory.
To be able to reclaim the memory, the description of the buffers has to fit
in the ffa_desc_buf.
Add a bounds check on the FF-A sharing path to prevent the memory reclaim
from failing.
Also do_ffa_mem_xfer() does not need __always_inline, except for the
BUILD_BUG_ON() aspect, which gets moved to a macro.
[maz: fixed the BUILD_BUG_ON() breakage with LLVM, thanks to Wei-Lin Chang
for the timely report]

Add explicit casting to prevent expantion of 32th bit of

For example, in inject_abt64:
ESR_ELx_EC_DABT_LOW << ESR_ELx_EC_SHIFT = 0x24 << 26.
This operation's result is int with 1 in 32th bit.
While casting this value into u64 (esr is u64) 1
fills 32 highest bits.

The DPI display interface feeds the external display pipeline. However
the pipeline representation is currently incomplete. Efforts are still
under way to come up with a way to represent the "creative" repurposing
of the DP bridge chip's internal output mux, which is meant to support
USB type-C orientation changes, to output to one of two type-C ports.
Until that is finalized, the external display can't be fully described,
and thus won't work. Even worse, the half complete graph potentially
confuses the OS, breaking the internal display as well.
Disable the external display interface across the whole Corsola family
until the DP / USB Type-C muxing graph binding is ready.

According to David and Ryan, there isn't a bug here, even though we
don't advance the PTE entry, because __ptep_set_access_flags() only
uses the access flags from the entry.
However, we always check pte_same(pte, entry) using the first entry
in __ptep_set_access_flags(). This means that the checks from 1 to
nr - 1 are not comparing the same PTE indexes (thus, they always
return false), which can be a bit confusing. To clarify the code, let's
add some comments.

ftrace_graph_ret_addr() takes an 'idx' integer pointer that is used to
optimize the stack unwinding process. arm64 currently passes `NULL` for
this parameter which stops it from utilizing these optimizations.
Further, the current code for ftrace_graph_ret_addr() will just return
the passed in return address if it is NULL which will break this usage.
Pass a valid integer pointer to ftrace_graph_ret_addr() similar to
x86_64's stack unwinder.

Arm Primecell blocks have a functional clock and a bus clock. The
Toshiba TMPV7708 only defines the bus clock (apb_pclk). Add the
"uartclk" and "sspclk" clocks to the PL011 and PL022 nodes,
respectively.

Commit 22e4e43484 ("arm64: dts: qcom: msm8939: Use mboxes
properties for APCS") broke the boot on msm8939 platforms.
The issue comes from the SMD driver failing to request the mbox
channel because of circular dependencies:
1. rpm -> apcs1_mbox -> rpmcc (RPM_SMD_XO_CLK_SRC) -> rpm.
2. rpm -> apcs1_mbox -> gcc -> rpmcc (RPM_SMD_XO_CLK_SRC) -> rpm
3. rpm -> apcs1_mbox -> apcs2 -> gcc -> rpmcc (RPM_SMD_XO_CLK_SRC) -> rpm
To fix this issue let's switch back to using the deprecated
qcom,ipc property for the RPM node.

Currently, BPF_CALL is always jited to indirect call. When target is
within the range of direct call, BPF_CALL can be jited to direct call.
For example, the following BPF_CALL
call __htab_map_lookup_elem
is always jited to indirect call:
mov x10, #0xffffffffffff18f4
movk x10, #0x821, lsl #16
movk x10, #0x8000, lsl #32
blr x10
When the address of target __htab_map_lookup_elem is within the range of
direct call, the BPF_CALL can be jited to:
bl 0xfffffffffd33bc98
This patch does such jit optimization by emitting arm64 direct calls for
BPF_CALL when possible, indirect calls otherwise.
Without this patch, the jit works as follows.
1. First pass
A. Determine jited position and size for each bpf instruction.
B. Computed the jited image size.
2. Allocate jited image with size computed in step 1.
3. Second pass
A. Adjust jump offset for jump instructions
B. Write the final image.
This works because, for a given bpf prog, regardless of where the jited
image is allocated, the jited result for each instruction is fixed. The
second pass differs from the first only in adjusting the jump offsets,
like changing "jmp imm1" to "jmp imm2", while the position and size of
the "jmp" instruction remain unchanged.
Now considering whether to jit BPF_CALL to arm64 direct or indirect call
instruction. The choice depends solely on the jump offset: direct call
if the jump offset is within 128MB, indirect call otherwise.
For a given BPF_CALL, the target address is known, so the jump offset is
decided by the jited address of the BPF_CALL instruction. In other words,
for a given bpf prog, the jited result for each BPF_CALL is determined
by its jited address.
The jited address for a BPF_CALL is the jited image address plus the
total jited size of all preceding instructions. For a given bpf prog,
there are clearly no BPF_CALL instructions before the first BPF_CALL
instruction. Since the jited result for all other instructions other
than BPF_CALL are fixed, the total jited size preceding the first
BPF_CALL is also fixed. Therefore, once the jited image is allocated,
the jited address for the first BPF_CALL is fixed.
Now that the jited result for the first BPF_CALL is fixed, the jited
results for all instructions preceding the second BPF_CALL are fixed.
So the jited address and result for the second BPF_CALL are also fixed.
Similarly, we can conclude that the jited addresses and results for all
subsequent BPF_CALL instructions are fixed.
This means that, for a given bpf prog, once the jited image is allocated,
the jited address and result for all instructions, including all BPF_CALL
instructions, are fixed.
Based on the observation, with this patch, the jit works as follows.
1. First pass
Estimate the maximum jited image size. In this pass, all BPF_CALLs
are jited to arm64 indirect calls since the jump offsets are unknown
because the jited image is not allocated.
2. Allocate jited image with size estimated in step 1.
3. Second pass
A. Determine the jited result for each BPF_CALL.
B. Determine jited address and size for each bpf instruction.
4. Third pass
A. Adjust jump offset for jump instructions.
B. Write the final image.

The reasons for PTEs in the kernel direct map to be marked invalid are not
limited to kfence / debug pagealloc machinery. In particular,
memfd_secret() also steals pages with set_direct_map_invalid_noflush().
When building the transitional page tables for kexec from the current
kernel's page tables, those pages need to become regular writable pages,
otherwise, if the relocation places kexec segments over such pages, a fault
will occur during kexec, leading to host going dark during kexec.
This patch addresses the kexec issue by marking any PTE as valid if it is
not none. While this fixes the kexec crash, it does not address the
security concern that if processes owning secret memory are not terminated
before kexec, the secret content will be mapped in the new kernel without
being scrubbed.

Add thermal trips for the two GPU thermal sensors found in the Allwinner A64.
There's only one GPU OPP defined since the commit 1428f0c19f ("arm64: dts:
allwinner: a64: Run GPU at 432 MHz"), so defining only the critical thermal
trips makes sense for the A64's two GPU thermal zones.
Having these critical thermal trips defined ensures that no hot spots develop
inside the SoC die that exceed the maximum junction temperature. That might
have been possible before, although quite unlikely, because the CPU and GPU
portions of the SoC are packed closely inside the SoC, so the overheating GPU
would inevitably result in the heat soaking into the CPU portion of the SoC,
causing the CPU thermal sensor to return high readings and trigger the CPU
critical thermal trips. However, it's better not to rely on the heat soak
and have the critical GPU thermal trips properly defined instead.

Permission Indirection Extension and Permission Overlay Extension can be
enabled independently.
When PIE is disabled and POE is enabled, the permissions set by POR_EL0 will be
applied on top of the permissions set in the PTE.
When both PIE and POE are enabled, the permissions set by POR_EL0 will be
applied on top of the permissions set by the PIRE0_EL1 register.
However PIRE0_EL1 has encodings that specifically enable and disable the
overlay from applying.
For example:
0001 Read, Overlay applied.
1000 Read, Overlay not applied.
Switch to using the 'Overlay applied' encodings in PIRE0_EL1, so that PIE and

The GW7905 was renamed to GW7500 before production release.
While we typically do not change compatibles, the GW7905 was never
released before its product name was changed to a GW7500.
The use the the 'xx' wildcard is to denote the fact that this
device-tree can support range of board models from GW7500 to GW7599 as
has been done historically with the Gateworks baseboards to support
various build customizatoins based on the same PCB.

The merge of imx-spdif driver into fsl-asoc-card brought
new DT properties that can be used with the "fsl,imx-audio-spdif"
compatible:
* The "spdif-controller" property from imx-spdif is named "audio-cpu"
in fsl-asoc-card.
* fsl-asoc-card uses codecs explicitly declared in DT
with "audio-codec".
With an S/PDIF, codec drivers spdif_transmitter and
spdif_receiver should be used.
Driver imx-spdif used instead the dummy codec and a pair of
boolean properties, "spdif-in" and "spdif-out".
While backward compatibility is kept to support properties
"spdif-controller", "spdif-in" and "spdif-out", using new properties has
several benefits:
* "audio-cpu" and "audio-codec" are more generic names reflecting
that the fsl-asoc-card driver supports multiple hardware.
They are properties already used by devices using the
fsl-asoc-card driver.
They are also similar to properties of simple-card: "cpu" and "codec".
* "spdif-in" and "spdif-out" imply the use of the dummy codec in the
driver. However, there are already two codec drivers for the S/PDIF,
spdif_transmitter and spdif_receiver.
It is better to declare S/PDIF Tx and Rx devices in a DT, and then
reference them with "audio-codec" than using the dummy codec.
For those reasons, this commit updates in-tree DTs to use the new
properties:
* Rename "spdif-controller" property to "audio-cpu".
* Declare S/PDIF transmitter and/or receiver devices, and use them with
the "audio-codec" property instead of "spdif-out" and/or "spdif-in".
These modifications were tested only on an imx8mn-evk board.
Note that out-of-tree and old DTs are still supported.
