[PATCH v2 08/17] powerpc: Add little endian variants of LWZX_BE and STWX_BE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



To support getrandom in VDSO which is based on little endian storage,
add macros equivalent to LWZX_BE and STWX_BE for little endian
accesses.

Put them outside of __powerpc64__ #ifdef so that they can also be used
for PPC32.
