Extend the 'set_memory_region_test' with an x86-only test case which
covers emulated MMIO during event vectoring error handling. The test case
1) Sets an IDT descriptor base to point to an MMIO address
2) Generates a #GP in the guest
3) Verifies userspace gets the correct exit reason, suberror code, and
GPA in internal.data[3]
Opportunistically add a definition for a non-canonical address to
processor.h so that the source of the #GP is somewhat self-documenting,
and so that future tests don't have to reinvent the wheel.

Rework x86's KVM PV features test to align with KVM's new, fixed behavior
of not allowing userspace to disable HLT-exiting after vCPUs have been
created. Rework the core testcase to disable HLT-exiting before creating
a vCPU, and opportunistically modify keep the paired VM+vCPU creation to
verify that KVM rejects KVM_CAP_X86_DISABLE_EXITS as expected.

Actually check for KVM support for disabling HLT-exiting instead of
effectively checking that KVM_CAP_X86_DISABLE_EXITS is #defined to a
non-zero value, and convert the TEST_REQUIRE() to a simple return so
that only the sub-test is skipped if HLT-exiting is mandatory.
The goof has likely gone unnoticed because all x86 CPUs support disabling
HLT-exiting, only systems with the opt-in mitigate_smt_rsb KVM module
param disallow HLT-exiting.

Extend x86's set sregs test to verify that KVM sets/clears OSXSAVE and
OSKPKE according to CR4.XSAVE and CR4.PKE respectively. For performance
reasons, KVM is responsible for emulating the architectural behavior of
the OS CPUID bits tracking CR4.

Refresh selftests' CPUID cache in the vCPU structure when querying a CPUID
entry so that tests don't consume stale data when KVM modifies CPUID as a
side effect to a completely unrelated change. E.g. KVM adjusts OSXSAVE in
response to CR4.OSXSAVE changes.
Unnecessarily invoking KVM_GET_CPUID is suboptimal, but vcpu->cpuid exists
to simplify selftests development, not for performance reasons. And,
unfortunately, trying to handle the side effects in tests or other flows
is unpleasant, e.g. selftests could manually refresh if KVM_SET_SREGS is
successful, but that would still leave a gap with respect to guest CR4
changes.

Rework x86's set sregs test to verify that KVM enforces CPUID vs. CR4
features even if userspace hasn't explicitly set guest CPUID. KVM used to
allow userspace to set any KVM-supported CR4 value prior to KVM_SET_CPUID2,
and the test verified that behavior.
However, the testcase was written purely to verify KVM's existing behavior,
i.e. was NOT written to match the needs of real world VMMs.
Opportunistically verify that KVM continues to reject unsupported features
after KVM_SET_CPUID2 (using KVM_GET_SUPPORTED_CPUID).

Now that KVM selftests uses the kernel's canonical arch paths, directly
override ARCH to 'x86' when targeting x86_64 instead of defining ARCH_DIR
to redirect to appropriate paths. ARCH_DIR was originally added to deal
with KVM selftests using the target triple ARCH for directories, e.g.
s390x and aarch64; keeping it around just to deal with the one-off alias
from x86_64=>x86 is unnecessary and confusing.
Note, even when selftests are built from the top-level Makefile, ARCH is
scoped to KVM's makefiles, i.e. overriding ARCH won't trip up some other
selftests that (somehow) expects x86_64 and can't work with x86.

Use the kernel's canonical $(ARCH) paths instead of the raw target triple
for KVM selftests directories. KVM selftests are quite nearly the only
place in the entire kernel that using the target triple for directories,
tools/testing/selftests/drivers/s390x being the lone holdout.
Using the kernel's preferred nomenclature eliminates the minor, but
annoying, friction of having to translate to KVM's selftests directories,
e.g. for pattern matching, opening files, running selftests, etc.
Opportunsitically delete file comments that reference the full path of the
file, as they are obviously prone to becoming stale, and serve no known
purpose.

Provide empty targets for KVM selftests if the target architecture is
unsupported to make it obvious which architectures are supported, and so
that various side effects don't fail and/or do weird things, e.g. as is,
"mkdir -p $(sort $(dir $(TEST_GEN_PROGS)))" fails due to a missing operand,
and conversely, "$(shell mkdir -p $(sort $(OUTPUT)/$(ARCH_DIR) ..." will
create an empty, useless directory for the unsupported architecture.
Move the guts of the Makefile to Makefile.kvm so that it's easier to see
that the if-statement effectively guards all of KVM selftests.

Add two phases to mmu_stress_test to verify that KVM correctly handles
guest memory that was writable, and then made read-only in the primary MMU,
and then made writable again.
Add bonus coverage for x86 and arm64 to verify that all of guest memory was
marked read-only. Making forward progress (without making memory writable)
requires arch specific code to skip over the faulting instruction, but the
test can at least verify each vCPU's starting page was made read-only for
other architectures.

Don't check for an unhandled exception if KVM_RUN failed, e.g. if it
returned errno=EFAULT, as reporting unhandled exceptions is done via a
ucall, i.e. requires KVM_RUN to exit cleanly. Theoretically, checking
for a ucall on a failed KVM_RUN could get a false positive, e.g. if there
were stale data in vcpu->run from a previous exit.

Ideally, the assert would be done at compile-time, but that would limit

Return a uint64_t from vcpu_get_reg() instead of having the caller provide
a pointer to storage, as none of the vcpu_get_reg() usage in KVM selftests
accesses a register larger than 64 bits, and vcpu_set_reg() only accepts a
64-bit value. If a use case comes along that needs to get a register that
is larger than 64 bits, then a utility can be added to assert success and
take a void pointer, but until then, forcing an out param yields ugly code
and prevents feeding the output of vcpu_get_reg() into vcpu_set_reg().

With the attr.c code moved to a shell test, there is no need to link
the test code into the python dso to avoid a missing reference to
test_attr__open. Drop the test code from the python library.
With the bench and test code removed from the python library on my x86
debian derived laptop the python library is reduced in size by 508,712
bytes or nearly 5%.

perf_kwork_add_work is declared in builtin-kwork, whereas much kwork
code is in util. To avoid needing to stub perf_kwork_add_work in
python.c, add a callback to struct perf_kwork and initialize it in
builtin-kwork to perf_kwork_add_work - this is the only struct
perf_kwork. This removes the need for the stub in python.c.

Avoid `perf bench internals inject-build-id` referencing the
cmd_inject sub-command that requires perf-bench to backward reference
internals of builtins. Replace the reference to cmd_inject with a call
to main. To avoid python.c needing to link with something providing
main, drop the libperf-bench library from the python shared object.

Move arch_syscalls__strerrno_function out of builtin-trace.c to env.c
so that there isn't a util to builtin function call. This allows the
python.c stub to be removed. Also, remove declaration/prototype from
env.h and make static to reduce scope. The include is moved inside
ifdefs to avoid, "defined but unused warnings".

archinsn.c containing arch_fetch_insn was only enabled with
CONFIG_AUXTRACE, but this meant that a NO_AUXTRACE build on x86 would
use the empty weak version of arch_fetch_insn - weak symbols are a
frequent source of errors like this and are outside of the C
specification. Change it so that archinsn.c is always built on x86 and
make the weak symbol empty version of arch_fetch_insn a strong one
guarded by ifdefs.
arch_fetch_insn on x86 depends on insn_decode which is a function
included then built into intel-pt-insn-decoder.c.
intel-pt-insn-decoder.c isn't built in a NO_AUXTRACE=1 build. Separate
the insn_decode function from intel-pt-insn-decoder.c by just directly
compiling the relevant file. Guard this compilation to be for either
always on x86 (because of the use in arch_fetch_insn) or when auxtrace
is enabled. Apply the CFLAGS overrides as necessary, reducing the amount
of code where warnings are disabled.
