powerpc/vdso32: Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE
This is copied and adapted from commit 5c929885f1bb ("powerpc/vdso64:
Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE")
from Santosh Sivaraj <[email protected]>
Benchmark from vdsotest-all:
clock-gettime-realtime: syscall: 3601 nsec/call
clock-gettime-realtime: libc: 1072 nsec/call
clock-gettime-realtime: vdso: 931 nsec/call
clock-gettime-monotonic: syscall: 4034 nsec/call
clock-gettime-monotonic: libc: 1213 nsec/call
clock-gettime-monotonic: vdso: 1076 nsec/call
clock-gettime-realtime-coarse: syscall: 2722 nsec/call

clock-gettime-realtime-coarse: vdso: 668 nsec/call
clock-gettime-monotonic-coarse: syscall: 2949 nsec/call
clock-gettime-monotonic-coarse: libc: 882 nsec/call
clock-gettime-monotonic-coarse: vdso: 745 nsec/call
Additional test passed with:
