Subject: [PATCH 2/2] selftests: timers: Remove local NSEC_PER_SEC and USEC_PER_SEC defines
Remove local NSEC_PER_SEC and USEC_PER_SEC defines. Pick them up from
include/vdso/time64.h. This requires -I $(top_srcdir) to the timers
Makefile to include the include/vdso/time64.h.
posix_timers test names the defines NSECS_PER_SEC and USECS_PER_SEC.
Include the include/vdso/time64.h and change NSECS_PER_SEC and
USECS_PER_SEC references to NSEC_PER_SEC and USEC_PER_SEC respectively.
