2017-03-29bitops.h: Include bitsperlong.h as needed for GENMASK_ULLStefan Roese
The macro GENMASK_ULL needs the BITS_PER_LONG_LONG macro which is defined in the bitsperlong.h header. Lets include this header as the upcoming A7k/8k support in the Marvell mvpp2 ethernet driver uses this macro.

2015-10-21linux/bitops.h: GENMASK copy from linuxJagan Teki
GENMASK is used to create a contiguous bitmask([hi:lo]). This patch is a copy from Linux, with below commit details "bitops: Fix shift overflow in GENMASK macros" (sha1: 00b4d9a14125f1e51874def2b9de6092e007412d) Cc: Tom Rini <trini@konsulko.com> Cc: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Jagan Teki <jteki@openedev.com>
2015-10-21linux/bitops: Move BIT definitions at topJagan Teki
Since it's a copy from Linux, this patch moved all BIT definitions to top so-that it looks same as Linux file. Cc: Tom Rini <trini@konsulko.com> Cc: Albert ARIBAUD <albert.u.boot@aribaud.net> Signed-off-by: Jagan Teki <jteki@openedev.com>

This patch corrects that by using PLATFORM_xxx instead of the name itself.

2009-09-15Define ffs/fls for all architecturesSimon Kagstrom
UBIFS requires fls(), which is not defined for arm (and some other architectures) and this patch adds it. The implementation is taken from Linux and is generic. ffs() is also defined for those that miss it. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>
2009-09-15Move __set/clear_bit from ubifs.h to bitops.hSimon Kagstrom
__set_bit and __clear_bit are defined in ubifs.h as well as in asm/include/bitops.h for some architectures. This patch moves the generic implementation to include/linux/bitops.h and uses that unless it's defined by the architecture. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>
