Message-Id: <1376485619-5166-1-git-send-email-akinobu.mita@gmail.com> Date: Wed, 14 Aug 2013 22:06:59 +0900 From: Akinobu Mita <akinobu.mita@...il.com> To: linux-kernel@...r.kernel.org Cc: Akinobu Mita <akinobu.mita@...il.com>, Tony Luck <tony.luck@...el.com>, Fenghua Yu <fenghua.yu@...el.com>, linux-ia64@...r.kernel.org Subject: [PATCH] ia64: use asm-generic/bitops/builtin-ffs.h The definision of ffs() for ia64 is almost same as asm-generic/bitops/builtin-ffs.h. The only difference is that it is defined as inline function or macro function. So this switches to use the header.
