The attached patch provides an out-of-line implementation of find_next_bit()
and rearranges linux/bitops.h to avoid a dependency loop between inline
functions in there and in asm/bitops.h trying to include one another.

"sparse" warns about implicit type conversions that may cause
surprising results. Did you know that large decimal types have
different type conversions from large hexadecimals?

From: Matthew Dobson <colpatch@us.ibm.com>
This patch implements a generic version of the nr_cpus_node(node) macro
implemented for ppc64 by the previous patch.
The generic version simply computes an hweight of the bitmask returned by
node_to_cpumask(node) topology macro.
This patch also adds a generic_hweight64() function and an hweight_long()
function which are used as helpers for the generic nr_cpus_node() macro.
This patch also adds a for_each_node_with_cpus() macro, which is used in
sched_best_cpu() in kernel/sched.c to fix the original problem of
scheduling processes on CPU-less nodes. This macro should also be used in
the future to avoid similar problems.
Test compiled and booted by Andrew Theurer (habanero@us.ibm.com) on both
x440 and ppc64.

depending on whether the constant is a hexadecimal one as
opposed to a decimal one?
Let's make it all explicit. There are probably more lurking
around, these were found during development of my C checker tool.

Here's suspend-to-{RAM,disk} combined patch for
2.5.17. Suspend-to-disk is pretty stable and was tested in
2.4-ac. Suspend-to-RAM is little more experimental, but works for me,
and is certainly better than disk-eating version currently in kernel.
Major parts are: process stopper, S3 specific code, S4 specific
code.
