ab0e9c4b91 selftests: kvm: return Kselftest Skip code for skipped tests
When kvm test is skipped because of unmet dependencies and/or unsupported
configuration, it exits with error which is treated as a fail by the
Kselftest framework. This leads to false negative result even when the test
could not be run.

Change it to return kselftest skip code when a test gets skipped to clearly
report that the test could not be run.

Change it to use ksft_exit_skip() when the test is skipped. In addition,
refine test_assert() message to include strerror() string and add explicit
check for EACCES to cleary identify when test doesn't run when access is
denied to resources required e.g: open /dev/kvm failed, rc: -1 errno: 13

bcb2b94ae0 KVM: selftests: exit with 0 status code when tests cannot be run
Right now, skipped tests are returning a failure exit code if /dev/kvm does
not exists.  Consistently return a zero status code so that various scripts
over the interwebs do not complain.  Also return a zero status code if
the KVM_CAP_SYNC_REGS capability is not present, and hardcode in the
test the register kinds that are covered (rather than just using whatever
value of KVM_SYNC_X86_VALID_FIELDS is provided by the kernel headers).

d5edb7f8e7 kvm: selftests: add vmx_tsc_adjust_test
The test checks the behavior of setting MSR_IA32_TSC in a nested guest,
and the TSC_OFFSET VMCS field in general.  It also introduces the testing
infrastructure for Intel nested virtualization.

lib/kvm_util.c: In function ‘kvm_memcmp_hva_gva’:
lib/kvm_util.c:332:2: error: ‘for’ loop initial declarations are only allowed in C99 mode

So add -std=gnu99 to CFLAGS
