Subject: [0/3] Improve generic fls64 for 64-bit machines
Date: Sat, 15 Mar 2008 18:29:14 +0100	[thread overview]
Message-ID: <20080315172913.GA21648@mailshack.com> (raw)

This series of patches:

[1/3] adds __fls.h to asm-generic
[2/3] modifies asm-*/bitops.h for 64-bit archs to implement __fls
[3/3] modifies asm-generic/fls64.h to make use of __fls

I have compiled i386 and x86_64, and they generate the same code as
before the change. The changes to the other archs are a best effort.
Please comment.

If this patch series is accepted, it will make one tiny bit of
the x86-unification a tiny bit cleaner. The patches are against
Linus' current tree.

Andrew, if no concensus can be reached that this is a bad patch
series, would you be willing to add this to your tree?

Greetings,
	Alexander
