Subject: [PATCH 1/2] m68k: bitops - offset == ((long)p - (long)vaddr) * 8
Date: Sun, 3 Apr 2011 15:11:16 +0200 [thread overview]
Message-ID: <1301836277-30185-1-git-send-email-geert@linux-m68k.org> (raw)
Hence use "offset" in find_next_{,zero_}bit(), like is already done for
find_next_{,zero_}bit_le()
