0c3a877469 KVM: selftests: Use u32 instead of uint32_t
Use u32 instead of uint32_t to make the KVM selftests code more concise
and more similar to the kernel (since selftests are primarily developed
by kernel developers).

This commit was generated with the following command:

  git ls-files tools/testing/selftests/kvm | xargs sed -i 's/uint32_t/u32/g'

Then by manually adjusting whitespace to make checkpatch.pl happy.

No functional change intended.

95826e1ed3 KVM: selftests: Convert arch_timer tests to common helpers to pin task
Convert the arch timer tests to use __pin_task_to_cpu() and
pin_self_to_cpu().

No functional change intended.

2b7deea3ec Revert "kvm: selftests: move base kvm_util.h declarations to kvm_util_base.h"
Effectively revert the movement of code from kvm_util.h => kvm_util_base.h,
as the TL;DR of the justification for the move was to avoid #idefs and/or
circular dependencies between what ended up being ucall_common.h and what
was (and now again, is), kvm_util.h.

But avoiding #ifdef and circular includes is trivial: don't do that.  The
cost of removing kvm_util_base.h is a few extra includes of ucall_common.h,
but that cost is practically nothing.  On the other hand, having a "base"
version of a header that is really just the header itself is confusing,
and makes it weird/hard to choose names for headers that actually are
"base" headers, e.g. to hold core KVM selftests typedefs.

For all intents and purposes, this reverts commit
7d9a662ed9.

730cfa45b5 KVM: selftests: Define _GNU_SOURCE for all selftests code
Define _GNU_SOURCE is the base CFLAGS instead of relying on selftests to
manually #define _GNU_SOURCE, which is repetitive and error prone.  E.g.
kselftest_harness.h requires _GNU_SOURCE for asprintf(), but if a selftest
includes kvm_test_harness.h after stdio.h, the include guards result in
the effective version of stdio.h consumed by kvm_test_harness.h not
defining asprintf():

  In file included from x86_64/fix_hypercall_test.c:12:
  In file included from include/kvm_test_harness.h:11:
 ../kselftest_harness.h:1169:2: error: call to undeclared function
  'asprintf'; ISO C99 and later do not support implicit function declarations
  [-Wimplicit-function-declaration]
   1169 |         asprintf(&test_name, "%s%s%s.%s", f->name,
        |         ^

When including the rseq selftest's "library" code, #undef _GNU_SOURCE so
that rseq.c controls whether or not it wants to build with _GNU_SOURCE.

c20dd9e069 KVM: arm64: selftests: Split arch_timer test code
Split the arch-neutral test code out of aarch64/arch_timer.c
and put them into a common arch_timer.c. This is a preparation
to share timer test codes in riscv.
