On powerpc, RODATA_TEST fails with message the following messages:

This is because GCC allocates it to .data section:

On POWER9 DD2.1 and below, it's possible for a paste instruction to
cause a Machine Check Exception (MCE) where only DSISR bit 33 is
set. This will result in the MCE handler seeing an unknown event,
which triggers linux to crash.
We change this by detecting unknown events caused by load/stores in

There is some room to optimize memcmp() in powerpc 64 bits version for

From: Simon Guo
Currently memcmp() 64bytes version in powerpc will fall back to .Lshort
(compare per byte mode) if either src or dst address is not 8 bytes
aligned. It can be opmitized if both addresses are with the same offset
with 8 bytes boundary.

This patch adjust selftest memcmp_64 so that memcmp selftest can be

It also adds testcases for memcmp over 4K bytes size.
