cae5f5151d thunderbolt: Add USB4 port devices
Create devices for each USB4 port. This is needed when we add retimer
access when there is no device connected but may be useful for other
purposes too following what USB subsystem does. This exports a single
attribute "link" that shows the type of the USB4 link (or "none" if
there is no cable connected).

0f28879cf6 thunderbolt: Log the link as TBT instead of TBT3
The upstream port can be connected to any previous generation
Thunderbolt port so logging as "TBT" is more accurate than "TBT3.

6ed541c53e thunderbolt: Allocate credits according to router preferences
The USB4 Connection Manager guide provides detailed information how the
USB4 router buffer (credit) allocation information should be used by the
connection manager when it allocates buffers for different paths. This
patch implements it for Linux. For USB 3.x and DisplayPort we use
directly the router preferences. The rest of the buffer space is then
used for PCIe and DMA (peer-to-peer, XDomain) traffic. DMA tunnels
require at least one buffer and PCIe six, so if there is not enough
buffers we fail the tunnel creation.

For the legacy Thunderbolt 1-3 devices we use the existing hard-coded
scheme except for DMA where we use the values suggested by the USB4 spec
chapter 13.

56ad3aef5c thunderbolt: Read router preferred credit allocation information
USB4 routers must expose their preferred credit (buffer) allocation
information through router operation. This information tells the
connection manager how the router prefers its buffers to be allocated to
get the expected bandwidth for the supported protocols.

Read this information and store it as part of struct tb_switch for each
USB4 router.

e7051beab8 thunderbolt: Wait for the lanes to actually bond
It may take some time until the two lanes enter bonded state so poll for
the link width to match what is expected before going forward. This ensures
the link is in expected state before we start establishing paths through
it.

ddc4739169 seccomp: Refactor notification handler to prepare for new semantics
This refactors the user notification code to have a do / while loop around
the completion condition. This has a small change in semantic, in that
previously we ignored addfd calls upon wakeup if the notification had been
responded to, but instead with the new change we check for an outstanding
addfd calls prior to returning to userspace.

Rodrigo Campos also identified a bug that can result in addfd causing
an early return, when the supervisor didn't actually handle the
syscall [1].

000ac42953 selftests: kvm: fix overlapping addresses in memslot_perf_test
vm_create allocates memory and maps it close to GPA.  This memory
is separate from what is allocated in subsequent calls to
vm_userspace_mem_region_add, so it is incorrect to pass the
test memory size to vm_create_default.  Just pass a small
fixed amount of memory which can be used later for page table,
otherwise GPAs are already allocated at MEM_GPA and the
test aborts.

Commit 4a1e10d5b5 ("KVM: x86: handle hardware breakpoints during emulation())
adds hardware breakpoints check before emulation the instruction and parts of
emulation context initialization, actually we don't have the EMULTYPE_NO_DECODE flag
here and the emulation context will not be reused. Commit c8848cee74 ("KVM: x86:
set ctxt->have_exception in x86_decode_insn()) triggers the warning because it
catches the stale emulation context has #UD, however, it is not during instruction
decoding which should result in EMULATION_FAILED. This patch fixes it by moving
the second part emulation context initialization into init_emulate_ctxt() and
before hardware breakpoints check. The ctxt->ud will be dropped by a follow-up
patch.

8fc4e4aa2b perf vendor events powerpc: Fix eventcode of power10 JSON events
Fixed the eventcode values in the power10 JSON event files to prepend
"0x" since these are hexadecimal values.

The patch also changes the event description of the PM_EXEC_STALL_LOAD_FINISH
and PM_EXEC_STALL_NTC_FLUSH event and move some events to correct files.

This reverts commit 31fae7c8b1.

	I just noticed this causes the following regression in Linux

	the quirk handling.

So let's drop this.

2499042326 i2c: s3c2410: fix possible NULL pointer deref on read message after write
Interrupt handler processes multiple message write requests one after
another, till the driver message queue is drained.  However if driver
encounters a read message without preceding START, it stops the I2C
transfer as it is an invalid condition for the controller.  At least the
comment describes a requirement "the controller forces us to send a new
START when we change direction".  This stop results in clearing the
message queue (i2c->msg = NULL).

The code however immediately jumped back to label "retry_write" which
dereferenced the "i2c->msg" making it a possible NULL pointer
dereference.

The Coverity analysis:
1. Condition !is_msgend(i2c), taking false branch.
   if (!is_msgend(i2c)) {

2. Condition !is_lastmsg(i2c), taking true branch.
   } else if (!is_lastmsg(i2c)) {

3. Condition i2c->msg->flags & 1, taking true branch.
   if (i2c->msg->flags & I2C_M_RD) {

4. write_zero_model: Passing i2c to s3c24xx_i2c_stop, which sets i2c->msg to NULL.
   s3c24xx_i2c_stop(i2c, -EINVAL);

5. Jumping to label retry_write.
   goto retry_write;

6. var_deref_model: Passing i2c to is_msgend, which dereferences null i2c->msg.
   if (!is_msgend(i2c)) {"

All previous calls to s3c24xx_i2c_stop() in this interrupt service
routine are followed by jumping to end of function (acknowledging
the interrupt and returning).  This seems a reasonable choice also here
since message buffer was entirely emptied.
