8260 - Spurious interrupt when calling __sti()

At the left of the comment is 'SYNC', in uppercase.
According to "include/asm-ppc/ppc_asm.h", which defines the preprocessor
macro 'SYNC', it means something only if CONFIG_PPC601_SYNC_FIX
is defined. The comment seems to be old and imprecise.
After compiling the kernel, I disassembled it, just to be sure... ;-)
