From 77b9bd9c49442407804c37bcc82021a35277f83c Mon Sep 17 00:00:00 2001 From: Alexander van Heukelum Date: Tue, 1 Apr 2008 11:46:19 +0200 Subject: x86: generic versions of find_first_(zero_)bit, convert i386 Generic versions of __find_first_bit and __find_first_zero_bit are introduced as simplified versions of __find_next_bit and __find_next_zero_bit. Their compilation and use are guarded by a new config variable GENERIC_FIND_FIRST_BIT. The generic versions of find_first_bit and find_first_zero_bit are implemented in terms of the newly introduced __find_first_bit and __find_first_zero_bit. This patch does not remove the i386-specific implementation, but it does switch i386 to use the generic functions by setting GENERIC_FIND_FIRST_BIT=y for X86_32.
