[PATCH] Remove nested feature sections
The {BEGIN,END}_FTR_SECTION asm macros used in ppc64 to nop out sections of code at runtime cannot be nested. However, we do nest them in hash_low.S. We get away with it there, because there is nothing between the BEGIN markers for each section. However, that's confusing to someone reading the code. This patch removes the nested ifset and ifclr feature sections, replacing them with a single feature section in the full mask/value form.
