PowerPC64 supports a 4PB virtual address space, but this test was
previously limited to 512TB. This patch extends the coverage up to the
full 4PB VA range on PowerPC64.
Memory from 0 to 128TB is allocated without an address hint, while
allocations from 128TB to 4PB use a hint address.

Patch series "selftests/mm: Fix false positives and skip unsupported
tests", v4.
This patch series addresses false positives in the generic mm selftests
and skips tests that cannot run correctly due to missing features or
system limitations.
This patch (of 7):
In main(), the high address is stored in hptr, but for mark_range(), the
address passed is ptr, not hptr. Fixed this by changing ptr[i] to hptr[i]
in mark_range() function call.

Now we have updated all users of mm->flags to use the bitmap accessors,
repalce it with the bitmap version entirely.
We are then able to move to having 64 bits of mm->flags on both 32-bit and
64-bit architectures.
We also update the VMA userland tests to ensure that everything remains
functional there.
No functional changes intended, other than there now being 64 bits of
available mm_struct flags.

Currently it hard codes the number of hugepage to check for

on a number passed in.

... and hide it behind a kconfig option. There is really no need for any
!xen code to perform this check.
The naming is a bit off: we want to find the "normal" page when a PTE was
marked "special". So it's really not "finding a special" page.
Improve the documentation, and add a comment in the code where XEN ends up
performing the pte_mkspecial() through a hypercall. More details can be
found in commit 923b2919e2c3 ("xen/gntdev: mark userspace PTEs as special
on x86 PV guests").

Patch series " execute PROCMAP_QUERY ioctl under per-vma lock", v4.
With /proc/pid/maps now being read under per-vma lock protection we can
reuse parts of that code to execute PROCMAP_QUERY ioctl also without
taking mmap_lock. The change is designed to reduce mmap_lock contention
and prevent PROCMAP_QUERY ioctl calls from blocking address space updates.
This patchset was split out of the original patchset [1] that introduced
per-vma lock usage for /proc/pid/maps reading. It contains PROCMAP_QUERY
tests, code refactoring patch to simplify the main change and the actual
transition to per-vma lock.
This patch (of 3):
Extend /proc/pid/maps tearing tests to verify PROCMAP_QUERY ioctl operation
correctness while the vma is being concurrently modified.

Add "extern" to the glibc-defined weak rseq symbols to convert the rseq
selftest's usage from weak symbol definitions to weak symbol _references_.
Effectively re-defining the glibc symbols wreaks havoc when building with
-fno-common, e.g. generates segfaults when running multi-threaded programs,
as dynamically linked applications end up with multiple versions of the
symbols.
Building with -fcommon, which until recently has the been the default for
GCC and clang, papers over the bug by allowing the linker to resolve the
weak/tentative definition to glibc's "real" definition.
Note, the symbol itself (or rather its address), not the value of the
symbol, is set to 0/NULL for unresolved weak symbol references, as the
symbol doesn't exist and thus can't have a value. Check for a NULL rseq
size pointer to handle the scenario where the test is statically linked
against a libc that doesn't support rseq in any capacity.

When cross-compiling the perf tool for ARM64, `perf help` may crash
with the following assertion failure:
help.c:122: exclude_cmds: Assertion `cmds->names[ci] == NULL' failed.
This happens when the perf binary is not named exactly "perf" or when
multiple "perf-*" binaries exist in the same directory. In such cases,
the `excludes` command list can be empty, which leads to the final
assertion in exclude_cmds() being triggered.
Add a simple guard at the beginning of exclude_cmds() to return early
if excludes->cnt is zero, preventing the crash.

The function parse_events__sort_events_and_fix_groups is needed to fix
uncore events like:
```
$ perf stat -e '{data_read,data_write}' ...
```
so that the multiple uncore PMUs have a group each of data_read and
data_write events.
The same function will perform architecture sorting and group fixing,
in particular for Intel topdown/perf-metric events. Grouping multiple
perf metric events together causes perf_event_open to fail as the
group can only support one. This means command lines like:
```
$ perf stat -e 'slots,slots' ...
```
fail as the slots events are forced into a group together to try to
satisfy the perf-metric event constraints.
As the user may know better than
parse_events__sort_events_and_fix_groups add a 'X' modifier to skip
its regrouping behavior. This allows the following to succeed rather
than fail on the second slots event being opened:
```
$ perf stat -e 'slots,slots:X' -a sleep 1
Performance counter stats for 'system wide':
6,834,154,071 cpu_core/slots/ (50.13%)
5,548,629,453 cpu_core/slots/X (49.87%)

Pass errno to stat_handle_error() rather than reading errno after it has
potentially been clobbered.
Move "skippable" handling first as a skippable event (from the perf stat
default list) should always just be skipped.
Remove logic to skip rather than fail events in a group when they
aren't the group leader.
The original logic was added in commit cb5ef60067c1 ("perf stat: Error
out unsupported group leader immediately") due to error handling and
opening being together and an assertion being raised.
Not failing this case causes broken groups to not report values,
particularly for topdown events.

Extend arch_evsel__open_strerror() from just AMD IBS events to Intel
core PMU events, to give a message when a slots event isn't a group
leader or when a perf metric event is duplicated within an event
group.
As generating the warning happens after non-arch specific warnings are
generated, disable the missing system wide (-a) flag warning for the
core PMU.
This assumes core PMU events should support per-thread/process and
system-wide.

The lzma_is_compressed and gzip_is_compressed functions are declared
to return a "bool" type, but in case of an error (e.g., file open
failure), they incorrectly returned -1.
A bool type is a boolean value that is either true or false.
Returning -1 for a bool return type can lead to unexpected behavior
and may violate strict type-checking in some compilers.
Fix the return value to be false in error cases, ensuring the function
adheres to its declared return type improves for preventing potential
bugs related to type mismatch.

Commit 21b8732eb447 ("perf tools: Allow overriding MAX_NR_CPUS at
compile time") added the capability to override MAX_NR_CPUS. At
that time it was necessary to reduce the huge amount of RAM used
by static stats variables.
But this has been unnecessary since commit 6a1e2c5c2673 ("perf stat:
Remove a set of shadow stats static variables"), and
commit e8399d34d568 ("libperf cpumap: Hide/reduce scope of
MAX_NR_CPUS") broke the build in that case because it failed to
add the guard around the new definition of MAX_NR_CPUS.
So cleanup things and remove guards completely to officialise it
is not necessary anymore to override MAX_NR_CPUS.

Usually the autodefer helpers in lib.sh are expected to be run in context
where success is the expected outcome. However when using them for feature
detection, failure can legitimately occur. But the failed command still
schedules a cleanup, which will likely fail again.
Instead, only schedule deferred cleanup when the positive command succeeds.
This way of organizing the cleanup has the added benefit that now the
return code from these functions reflects whether the command passed.

The fact that all cleanup (ideally) goes through the defer framework makes
debugging of these commands a bit tricky. However, this also gives us a
nice point to place a hook along the lines of PAUSE_ON_FAIL. When the
environment variable DEFER_PAUSE_ON_FAIL is set, and a cleanup command
results in non-zero exit status, show a bit of debuginfo and give the user
an opportunity to interrupt the execution altogether.

Add selftests for testing the reporting of arena page faults through BPF
streams. Two new bpf programs are added that read and write to an
unmapped arena address and the fault reporting is verified in the
userspace through streams.
The added bpf programs need to access the user_vm_start in struct
bpf_arena, this is done by casting &arena to struct bpf_arena *, but
barrier_var() is used on this ptr before accessing ptr->user_vm_start;
to stop GCC from issuing an out-of-bound access due to the cast from
smaller map struct to larger "struct bpf_arena"

Extend the fastops test to cover instructions that operate on 8-bit data.
Support for 8-bit instructions was omitted from the original commit purely
due to complications with BT not having a r/m8 variant. To keep the
RFLAGS.CF behavior deterministic and not heavily biased to '0' or '1',
continue using BT, but cast and load the to-be-tested value into a
dedicated 32-bit constraint.
Supporting 8-bit operations will allow using guest_test_fastops() as-is to
provide full coverage for DIV and IDIV. For divide operations, covering
all operand sizes _is_ interesting, because KVM needs provide exception
fixup for each size (failure to handle a #DE could panic the host).
