From 52d61227b66d4099b39c8309ab37cb67ee09a405 Mon Sep 17 00:00:00 2001 From: Simon Kagstrom Date: Mon, 24 Aug 2009 09:10:12 +0200 Subject: Define ffs/fls for all architectures 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.
