Subject: lib/bitmap.c: fix undefined shift in __bitmap_shift_{left|right}()
X-Git-Tag: omap-for-v3.19/fixes-not-urgent-part1~39^2~8

lib/bitmap.c: fix undefined shift in __bitmap_shift_{left|right}()

If __bitmap_shift_left() or __bitmap_shift_right() are asked to shift by
a multiple of BITS_PER_LONG, they will try to shift a long value by
BITS_PER_LONG bits which is undefined.  Change the functions to avoid
the undefined shift.
