Subject: powerpc: Remove unused st_le*() and ld_le* functions
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0eebf9b5d2da61f84cddd0ec2bb41be93f8fc82b;p=linux-beck.git

powerpc: Remove unused st_le*() and ld_le* functions

The powerpc specific st_le*() and ld_le*() functions in
arch/powerpc/asm/swab.h no longer have any users.  They are also
misleadingly named, since they always byteswap, even on a little-endian
host.

This patch removes them.
