From 44fd81fe7eb8029a37ec83f15d4ef3585dd81bb6 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Wed, 14 Aug 2013 22:06:59 +0900 Subject: [IA64] Use asm-generic/bitops/builtin-ffs.h The definition of ffs() for ia64 is almost the same as asm-generic/bitops/builtin-ffs.h. The only difference is whether it is defined as inline function or macro function. So this switches to use the header (both to reduce amount of arch specific code, and because inline functions provide type-checking that macros do not).
