The patch titled
define first set of BIT* macros
has been removed from the -mm tree. Its filename was
define-first-set-of-bit-macros.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: define first set of BIT* macros
From: Jiri Slaby <jirislaby@xxxxxxxxx>
define first set of BIT* macros
- move BITOP_MASK and BITOP_WORD from asm-generic/bitops/atomic.h to
include/linux/bitops.h and rename it to BIT_MASK and BIT_WORD
- move BITS_TO_LONGS and BITS_PER_BYTE to bitops.h too and allow easily
define another BITS_TO_something (e.g. in event.c) by BITS_TO_TYPE macro
Remaining (and common) BIT macro will be defined after all occurences and
conflicts will be sorted out in the patches.
