powerpc64le: Fix ifunc selection for memset, memmove, bzero and bcopy
|
|
|
|
The hwcap2 check for the aforementioned functions should check for
|
|
both PPC_FEATURE2_ARCH_3_1 and PPC_FEATURE2_HAS_ISEL but was
|
|
mistakenly checking for any one of them, enabling isa 3.1 version of
|
|
the functions in incompatible processors, like POWER8.
