Add test coverage for the KVM-defined GUEST_SSP "register" in the MSRs
test. While _KVM's_ goal is to not tie the uAPI of KVM-defined registers
to any particular internal implementation, i.e. to not commit in uAPI to
handling GUEST_SSP as an MSR, treating GUEST_SSP as an MSR for testing
purposes is a-ok and is a naturally fit given the semantics of SSP.

Extend the MSRs test to support {S,U}_CET, which are a bit of a pain to
handled due to the MSRs existing if IBT *or* SHSTK is supported. To deal
with Intel's wonderful decision to bundle IBT and SHSTK under CET, track
the second feature, but skip only RDMSR #GP tests to avoid false failures
when running on a CPU with only one of IBT or SHSTK (the WRMSR #GP tests
are still valid since the enable bits are per-feature).

Add a selftest to verify reads and writes to various MSRs, from both the
guest and host, and expect success/failure based on whether or not the
vCPU supports the MSR according to supported CPUID.
Note, this test is extremely similar to KVM-Unit-Test's "msr" test, but
provides more coverage with respect to host accesses, and will be extended
to provide addition testing of CPUID-based features, save/restore lists,
and KVM_{G,S}ET_ONE_REG, all which are extremely difficult to validate in
KUT.
If kvm.ignore_msrs=true, skip the unsupported and reserved testcases as
KVM's ABI is a mess; what exactly is supposed to be ignored, and when,
varies wildly.

Reduce the number of combinations of unavailable PMU events masks that are
testing by the PMU counters test. In reality, testing every possible
combination isn't all that interesting, and certainly not worth the tens
of seconds (or worse, minutes) of runtime. Fully testing the N^2 space
will be especially problematic in the near future, as 5! new arch events
are on their way.
Use alternating bit patterns (and 0 and -1u) in the hopes that _if_ there

only with a super specific pattern/value.

31:9 are currently reserved, silently truncating those bits is unnecessary

GNU getopt permutes argv to pull options to the front, ahead of

Thus these scripts stop working on musl since non-option arguments for

addr_switch_hint is defined as DFEFAULT_MAP_WINDOW in the failed test (for
x86_64, DFEFAULT_MAP_WINDOW is defined as (1UL<<47) - pagesize) in 64 bit.
Before commit cc92882ee2 ("mm: drop hugetlb_get_unmapped_area{_*}
functions"), for x86_64 hugetlb_get_unmapped_area() is handled in arch
code arch/x86/mm/hugetlbpage.c and addr is checked with
map_address_hint_valid() after align with 'addr &= huge_page_mask(h)'
which is a round down way, and it will fail the check because the addr is
within the DEFAULT_MAP_WINDOW but (addr + len) is above the
DFEFAULT_MAP_WINDOW. So it wil go through the
hugetlb_get_unmmaped_area_top_down() to find an area within the
DFEFAULT_MAP_WINDOW.
After commit cc92882ee2 ("mm: drop hugetlb_get_unmapped_area{_*}
functions"). The addr hint for hugetlb_get_unmmaped_area() will be
rounded up and aligned to hugepage size with ALIGN() for all arches. And
after the align, the addr will be above the default MAP_DEFAULT_WINDOW,
and the map_addresshint_valid() check will pass because both aligned addr
(addr0) and (addr + len) are above the DEFAULT_MAP_WINDOW, and the aligned
hint address (0x800000000000) is returned as an suitable gap is found
there, in arch_get_unmapped_area_topdown().
To still cover the case that addr is within the DEFAULT_MAP_WINDOW, and
addr + len is above the DFEFAULT_MAP_WINDOW, change to choose the last
hugepage aligned address within the DEFAULT_MAP_WINDOW as the hint addr,
and the addr + len (2 hugepages) will be one hugepage above the
DEFAULT_MAP_WINDOW. An aligned address won't be affected by the page
round up or round down from kernel, so it's determistic.

Patch series "Fix va_high_addr_switch.sh test failure", v3.
These three patches fix the va_high_addr_switch.sh test failure on x86_64.
Patch 1 fixes the hugepage setup issue that nr_hugepages is reset too
early in run_vmtests.sh and break the later va_high_addr_switch testing.
Patch 2 adds hugepage setup in va_high_addr_switch test, so that it can
still work if vm_runtests.sh changes the hugepage setup someday.
Patch 3 fixes the test failure caused by the hint addr align method change
in hugetlb_get_unmapped_area().
This patch (of 3):
The nr_hugepgs variable is used to keep the original nr_hugepages at the
hugepage setup step at test beginning. After userfaultfd test, a cleaup
is executed, both /sys/kernel/mm/hugepages/hugepages-*/nr_hugepages and
/proc/sys//vm/nr_hugepages are reset to 'original' value before
userfaultfd test starts.
Issue here is the value used to restore /proc/sys/vm/nr_hugepages is
nr_hugepgs which is the initial value before the vm_runtests.sh runs, not
the value before userfaultfd test starts. 'va_high_addr_swith.sh' tests
runs after that will possibly see no hugepages available for test, and got
EINVAL when mmap(HUGETLB), making the result invalid.
And before pkey tests, nr_hugepgs is changed to be used as a temp variable
to save nr_hugepages before pkey test, and restore it after pkey tests
finish. The original nr_hugepages value is not tracked anymore, so no way
to restore it after all tests finish.
Add a new variable orig_nr_hugepgs to save the original nr_hugepages, and
and restore it to nr_hugepages after all tests finish. And change to use
the nr_hugepgs variable to save the /proc/sys/vm/nr_hugeages after
hugepage setup, it's also the value before userfaultfd test starts, and
the correct value to be restored after userfaultfd finishes. The
va_high_addr_switch.sh broken will be resolved.

There is room for improvement, so let's clean up a bit:
(1) Define "4" as a constant.
(2) SKIP if we fail to allocate all THPs (e.g., fragmented) and add
recovery code for all other failure cases: no need to exit the test.
(3) Rename "len" to thp_area_size, and "one_page" to "thp_area".
(4) Allocate a new area "page_area" into which we will mremap the
pages; add "page_area_size". Now we can easily merge the two
mremap instances into a single one.
(5) Iterate THPs instead of bytes when checking for missed THPs after
mremap.
(6) Rename "pte_mapped2" to "tmp", used to verify mremap(MAP_FIXED)
result.
(7) Split the corruption test from the failed-split test, so we can just
iterate bytes vs. thps naturally.
(8) Extend comments and clarify why we are using mremap in the first
place.

Patch series "selftests/mm: split_huge_page_test: split_pte_mapped_thp
improvements", v2.
One fix for occasional failures I found while testing and a bunch of
cleanups that should make that test easier to digest.
This patch (of 2):
When checking for actual tail or head pages of a folio, we must make sure
that the KPF_COMPOUND_HEAD/KPF_COMPOUND_TAIL flag is paired with KPF_THP.
For example, if we have another large folio after our large folio in
physical memory, our "pfn_flags & (KPF_THP | KPF_COMPOUND_TAIL)" would
trigger even though it's actually a head page of the next folio.
If is_backed_by_folio() returns a wrong result, split_pte_mapped_thp() can
fail with "Some THPs are missing during mremap".
Fix it by checking for head/tail pages of folios properly. Add
folio_tail_flags/folio_head_flags to improve readability and use these
masks also when just testing for any compound page.

Some ublk selftests have strange behavior when fio is not installed.
While most tests behave correctly (run if they don't need fio, or skip
if they need fio), the following tests have different behavior:
- test_null_01, test_null_02, test_generic_01, test_generic_02, and
test_generic_12 try to run fio without checking if it exists first,
and fail on any failure of the fio command (including "fio command
not found"). So these tests fail when they should skip.
- test_stress_05 runs fio without checking if it exists first, but
doesn't fail on fio command failure. This test passes, but that pass
is misleading as the test doesn't do anything useful without fio
installed. So this test passes when it should skip.
Fix these issues by adding _have_program fio checks to the top of all of
these tests.
