Enhance the coccicheck script to filter *.cocci files based on the
specified MODE (e.g., report, patch). This ensures that only compatible
semantic patch files are executed, preventing errors such as:
"virtual rule report not supported"
This error occurs when a .cocci file does not define a 'virtual <MODE>'
rule, yet is executed in that mode.
For example:
make coccicheck M=drivers/hwtracing/coresight/ MODE=report
In this case, running "secs_to_jiffies.cocci" would trigger the error
because it lacks support for 'report' mode. With this change, such files
are skipped automatically, improving robustness and developer
experience.

clang is generating very inefficient code for native_save_fl() which is
used for local_irq_save() in critical spots.
Allowing the "pop %0" to use memory:
1) forces the compiler to add annoying stack canaries when
CONFIG_STACKPROTECTOR_STRONG=y in many places.
2) Almost always is followed by an immediate "move memory,register"
One good example is _raw_spin_lock_irqsave, with 8 extra instructions
ffffffff82067a30 <_raw_spin_lock_irqsave>:
ffffffff82067a30: ...
ffffffff82067a39: 53 push %rbx
// Three instructions to ajust the stack, read the per-cpu canary
// and copy it to 8(%rsp)
ffffffff82067a3a: 48 83 ec 10 sub $0x10,%rsp
ffffffff82067a3e: 65 48 8b 05 da 15 45 02 mov %gs:0x24515da(%rip),%rax # <__stack_chk_guard>
ffffffff82067a46: 48 89 44 24 08 mov %rax,0x8(%rsp)
ffffffff82067a4b: 9c pushf
// instead of pop %rbx, compiler uses 2 instructions.
ffffffff82067a4c: 8f 04 24 pop (%rsp)
ffffffff82067a4f: 48 8b 1c 24 mov (%rsp),%rbx
ffffffff82067a53: fa cli
ffffffff82067a54: b9 01 00 00 00 mov $0x1,%ecx
ffffffff82067a59: 31 c0 xor %eax,%eax
ffffffff82067a5b: f0 0f b1 0f lock cmpxchg %ecx,(%rdi)
ffffffff82067a5f: 75 1d jne ffffffff82067a7e <_raw_spin_lock_irqsave+0x4e>
// three instructions to check the stack canary
ffffffff82067a61: 65 48 8b 05 b7 15 45 02 mov %gs:0x24515b7(%rip),%rax # <__stack_chk_guard>

ffffffff82067a6e: 75 17 jne ffffffff82067a87
...
// One extra instruction to adjust the stack.
ffffffff82067a73: 48 83 c4 10 add $0x10,%rsp

Work around clang problems with "=rm" asm constraint.
clang seems to always chose the memory output, while it is almost
always the worst choice.
Add ASM_OUTPUT_RM so that we can replace "=rm" constraint
where it matters for clang, while not penalizing gcc.

- Add a missing 'break' to fix param parsing in the rseq selftest
- Apply runtime updates to the _current_ CPUID when userspace is

positive and to avoid dropping the pending update
- Disallow toggling KVM_MEM_GUEST_MEMFD on an existing memslot, as
it's not supported by KVM and leads to a use-after-free due to KVM
failing to unbind the memslot from the previously-associated
guest_memfd instance

e.g. for dirty logging
- Set exit_code[63:32] to -1 (all 0xffs) when synthesizing a nested
SVM_EXIT_ERR (a.k.a. VMEXIT_INVALID) #VMEXIT, as VMEXIT_INVALID is
defined as -1ull (a 64-bit value)
- Update SVI when activating APICv to fix a bug where a

due to SVI being stale
- Immediately refresh APICv controls (if necessary) on a nested

Since commit eb972eab0794 ("lkdtm/bugs: Add cases for BUG and PANIC
occurring in hardirq context"), building with clang for x86_64 results
in the following warnings:
vmlinux.o: warning: objtool: lkdtm_PANIC_IN_HARDIRQ(): unexpected end of section .text.lkdtm_PANIC_IN_HARDIRQ
vmlinux.o: warning: objtool: lkdtm_BUG_IN_HARDIRQ(): unexpected end of section .text.lkdtm_BUG_IN_HARDIRQ
caused by busy "while (wait_for_...);" loops. Add READ_ONCE() and
cpu_relax() to better indicate the intention and avoid any unwanted

Currently AMD IOMMU driver does not reserve domain ids programmed in the
DTE while reusing the device table inside kdump kernel. This can cause
reallocation of these domain ids for newer domains that are created by
the kdump kernel, which can lead to potential IO_PAGE_FAULTs
Hence reserve these ids inside pdom_ids.

The current validation 'wire_order[i] > ARRAY_SIZE(config_pins)' allows
wire_order[i] to equal ARRAY_SIZE(config_pins), which causes out-of-bounds
access when used as index in 'config_pins[wire_order[i]]'.
Since config_pins has 4 elements (indices 0-3), the valid range for
wire_order should be 0-3. Fix the off-by-one error by using >= instead
of > in the validation check.

Pull tracing fixes from Steven Rostedt:
- Add Documentation/core-api/tracepoint.rst to TRACING in MAINTAINERS
file
Updates to the tracepoint.rst document should be reviewed by the
tracing maintainers.
- Fix warning triggered by perf attaching to synthetic events
The synthetic events do not add a function to be registered when perf
attaches to them. This causes a warning when perf registers a
synthetic event and passes a NULL pointer to the tracepoint register
function.
Ideally synthetic events should be updated to work with perf, but as
that's a feature and not a bug fix, simply now return -ENODEV when
perf tries to register an event that has a NULL pointer for its
function. This no longer causes a kernel warning and simply causes
the perf code to fail with an error message.
- Fix 32bit overflow in option flag test
The option's flags changed from 32 bits in size to 64 bits in size.
Fix one of the places that shift 1 by the option bit number to to be
1ULL.
- Fix the output of printing the direct jmp functions
The enabled_functions that shows how functions are being attached by
ftrace wasn't updated to accommodate the new direct jmp trampolines
that set the LSB of the pointer, and outputs garbage. Update the
output to handle the direct jmp trampolines.

Under certain conditions (more prevalent after a suspend/resume cycle),
the touchscreen controller can send the "boot complete" interrupt before
it actually finished booting. In those cases, attempting to read touch
data resuls in a stream of "not ready" messages being read and
interpreted as a touch report. Check that the response is in fact a
touch report and discard it otherwise.
