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.

From: Simon Guo
There is some room to optimize memcmp() in powerpc 64 bits version for
following 2 cases:
(1) Even src/dst addresses are not aligned with 8 bytes at the beginning,
memcmp() can align them and go with .Llong comparision mode without
fallback to .Lshort
On powerpc, RODATA_TEST fails with message the following messages:
[6.199505] Freeing unused kernel memory: 528K
[6.203935] rodata_test: test data was not read only
This is because GCC allocates it to .data section:
c0695034 g O .data 0004 rodata_test_data
