[PATCH] remove powerpc bitops in favor of existing generic bitops

Browse Source 
There already exists a big endian safe bitops implementation in
lib/find_next_bit.c.  The code in it is 90%+ common with the powerpc
specific version, so the powerpc version is redundant.  This patch
makes the necessary changes to use the generic bitops in powerpc, and
removes the powerpc specific version.
