s390: fix strrchr() implementation
Fix two problems found in the strrchr() implementation for s390
architectures: evaluate empty strings (return the string address instead of
NULL, if '\0' is passed as second argument); evaluate the first character
of non-empty strings (the current implementation stops at the second).

Read vcpu->vcpu_idx directly instead of bouncing through the one-line wrapper, kvm_vcpu_get_idx(), and drop the wrapper. The wrapper is a remnant of the original implementation and serves no purpose; remove it before it gains more users. Back when kvm_vcpu_get_idx() was added by commit |

s390/bpf: Fix optimizing out zero-extensions
Currently the JIT completely removes things like `reg32 += 0`,
however, the BPF_ALU semantics requires the target register to be
zero-extended in such cases.
Fix by optimizing out only the arithmetic operation, but not the
subsequent zero-extension.

2nd batch of s390 updates for 5.15 merge window
- Fix topology update on cpu hotplug, so notifiers see expected masks. This bug
was uncovered with SCHED_CORE support.
- Fix stack unwinding so that the correct number of entries are omitted like
expected by common code. This fixes KCSAN selftests.
- Add kmemleak annotation to stack_alloc to avoid false positive kmemleak
warnings.
- Avoid layering violation in common I/O code and don't unregister subchannel
from child-drivers.
- Remove xpram device driver for which no real use case exists since the kernel
is 64 bit only. Also all hypervisors got required support removed in the
meantime, which means the xpram device driver is dead code.
- Fix -ENODEV handling of clp_get_state in our PCI code.
- Enable KFENCE in debug defconfig.
- Cleanup hugetlbfs s390 specific Kconfig dependency.
- Quite a lot of trivial fixes to get rid of "W=1" warnings, and and other
simple cleanups.

s390/topology: fix topology information when calling cpu hotplug notifiers
The cpu hotplug notifiers are called without updating the core/thread masks when a new CPU is added. This causes problems with code setting up data structures in a cpu hotplug notifier, and relying on that later in normal code. This caused a crash in the new core scheduling code (SCHED_CORE), where rq->core was set up in a notifier depending on cpu masks. To fix this, add a cpu_setup_mask which is used in update_cpu_masks() instead of the cpu_online_mask to determine whether the cpu masks should be set for a certain cpu. Also move update_cpu_masks() to update the masks before calling notify_cpu_starting() so that the notifiers are seeing the updated masks.

s390/unwind: use current_frame_address() to unwind current task
current_stack_pointer() simply returns current value of %r15. If current_stack_pointer() caller allocates stack (which is the case in unwind code) %r15 points to a stack frame allocated for callees, meaning current_stack_pointer() caller (e.g. stack_trace_save) will end up in the stacktrace. This is not expected by stack_trace_save*() callers and causes problems. current_frame_address() on the other hand returns function stack frame address, which matches %r15 upon function invocation. Using it in get_stack_pointer() makes it more aligned with x86 implementation (according to BACKTRACE_SELF_TEST output) and meets stack_trace_save*() caller's expectations, notably KCSAN. Also make sure unwind_start is always inlined.

memblock: make memblock_find_in_range method private
There are a lot of uses of memblock_find_in_range() along with memblock_reserve() from the times memblock allocation APIs did not exist. memblock_find_in_range() is the very core of memblock allocations, so any future changes to its internal behaviour would mandate updates of all the users outside memblock. Replace the calls to memblock_find_in_range() with an equivalent calls to memblock_phys_alloc() and memblock_phys_alloc_range() and make memblock_find_in_range() private method of memblock. This simplifies the callers, ensures that (unlikely) errors in memblock_reserve() are handled and improves maintainability of memblock_find_in_range().

mm/gup: remove try_get_page(), call try_get_compound_head() directly
try_get_page() is very similar to try_get_compound_head(), and in fact try_get_page() has fallen a little behind in terms of maintenance: try_get_compound_head() handles speculative page references more thoroughly. There are only two try_get_page() callsites, so just call try_get_compound_head() directly from those, and remove try_get_page() entirely. Also, seeing as how this changes try_get_compound_head() into a non-static function, provide some kerneldoc documentation for it.

asm-generic changes for 5.15
The main content for 5.15 is a series that cleans up the handling of
strncpy_from_user() and strnlen_user(), removing a lot of slightly
incorrect versions of these in favor of the lib/strn*.c helpers
that implement these correctly and more efficiently.
The only architectures that retain a private version now are
mips, ia64, um and parisc. I had offered to convert those at all,
but Thomas Bogendoerfer wanted to keep the mips version for the
moment until he had a chance to do regression testing.
The branch also contains two patches for bitops and for ffs().

Most of that code I did not manage to get tested and reviewed before the merge window opened but a handful of very useful cleanups are ready to be merged. The first change is simply the removal of the bdflush system call. The code has now been disabled long enough that even the oldest userspace working userspace setups anyone can find to test are fine with the bdflush system call being removed. Changing m68k fsp040_die to use force_sigsegv(SIGSEGV) instead of calling do_exit directly is interesting only in that it is nearly the most difficult of the incorrect uses of do_exit to remove. The change to the seccomp code to simply send a signal instead of calling do_coredump directly is a very nice little cleanup made possible by realizing the existing signal sending helpers were missing a little bit of functionality that is easy to provide" * 'exit-cleanups-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: signal/seccomp: Dump core when there is only one live thread signal/seccomp: Refactor seccomp signal and coredump generation signal/m68k: Use force_sigsegv(SIGSEGV) in fpsp040_die exit/bdflush: Remove the deprecated bdflush system call |

Driver core update for 5.15-rc1
Here is the big set of driver core patches for 5.15-rc1.
These do change a number of different things across different
subsystems, and because of that, there were 2 stable tags created that
might have already come into your tree from different pulls that did the
following
- changed the bus remove callback to return void
- sysfs iomem_get_mapping rework
The latter one will cause a tiny merge issue with your tree, as there
was a last-minute fix for this in 5.14 in your tree, but the fixup
should be "obvious". If you want me to provide a fixed merge for this,
please let me know.
Other than those two things, there's only a few small things in here:
- kernfs performance improvements for huge numbers of sysfs
users at once
- tiny api cleanups
- other minor changes
All of these have been in linux-next for a while with no reported
problems, other than the before-mentioned merge issue.

s390/entry: make oklabel within CHKSTG macro local
Make the oklabel within the CHKSTG macro local. This makes sure that
tools like objdump and the crash debugging tool still disassemble full
functions where the macro has been used instead of stopping half way
where such a global label is used and one has to guess how to
disassemble the rest of such a function:
E.g.:
0000000000cb0270 <mcck_int_handler>:
cb0270: b2 05 03 20 stck 800
...
cb0354: a7 74 00 97 jne cb0482 <oklabel270+0xe2>
0000000000cb0358 <oklabel243>:
