powerpc: Fix comment typos in arch/powerpc/include/asm/bitops.h
In arch/powerpc/include/asm/bitops.h, the comments about bit numbers in
large (> 1 word) bitmaps have two typos:
- On ppc64 system, the LSB of the 4th word should be bit 192 rather than
196, because if it's bit 196, bit 192-195 will be missing in the
bitmap.
- On ppc32 system, the LSB of the second word should be bit 32 rather
than 31, because bit 31 is already in the first word.
This patch fixes these typos.
