Here is another final K&R to ANSI C cleanup patch for zlib.

The members of struct sock got a prefix of 'sk_' recently.

This patch updates smbfs to match the new world order.

This changeset:

1. Implements hlist_add_after
2. uses prefetch in hlist_for_each, using a trick that ends up being
   equivalent to having the prefetch instruction in the first block
   of the hlist_for_each for block, the compiler optimizes the second
   "test" away, as its result is constant
3. implements hlist_for_each_entry and hlist_for_each_entry safe,
   using a struct hlist_node as iterator to avoid the extra branches a
   similar implementation to list_for_each_entry would have if used
   a typed iterator, but while avoiding having to have the explicit
   hlist_entry as in hlist_for_each.

4. Converts the hlist_for_each users that had explicit prefetches, i.e.
   removed the explicit prefetch

5. fix a harmless list_entry use in a hlist_for_each in inode.c

powernow-k7 needs dmi_broken

This patch works around a gcc 3.3 bug on AMD64.  On AMD64 the
get_current() function expands to a switch on sizeof which has to be
optimized away by the compiler, finally yielding an inline assembler
statement.  In some cases it seems to get that wrong and forgets to
reference and use the argument.  I have only seen it happen in
binfmt_elf so far.

Work around by just computing "current" once.

hugetlbfs was unnecessarily verbose, and didn't even print out the right
thing if given invalid mount options.

Just return EINVAL.

This reduces the number of warnings from Linus' `check' program
for stuff in arch/ppc.

An update to the ppc64 MAINTAINERS entry.

Trivial patch: when these were introduced cpu.h didn't exist.

 This adds a /proc/kallsyms if you have CONFIG_KALLSYMS in your
kernel.  The output is nm-like, with symbols in caps (global) if
exported using EXPORT_SYMBOL, rather than the normal static
vs. non-static differentiation.

This is useful for things like performance monitoring tools (profiling
etc) that want to match addresses to names in user space.

The loop thread is getting permanently stuck in balance_dirty_pages()
(nr_writeback is exceeded) because the loop thread itself is responsible for
completing writeback on behalf of higher layers.

So we need to take that out: don't throttle the loop thread.  Throttle the
tasks which are generating all the dirty data instead.

This resurrects the old /proc/sys/vm/free_pages functionality: the ability to
tell page reclaim how much free memory to maintain.

This may be needed for specialised networking applications, and it provides
an interesting way to stress the kernel: set it very low so atomic
allocations can easily fail.

Also, a 16G ppc64 box currently cruises along at 1M free memory, which is
surely too little to supporthigh-speed networking.  We have not changed that
setting here, but it is now possible to do so.

The patch also reduces the amount of free memory which the VM will maintain
in ZONE_HIGHMEM, as it is almost always wasted memory.

The change makes the transfer rate numbers come out right for the fibre
channel version of this controller.

For 1G FC, the NegotiatedSynchronousMegaTransfers is 1000, and the
NegotiatedDataWidthBIts is 1.  The old code assumed NegotiatedDataWidthBits
was always either 8 or 16.  The new code is simpler, and does the
calculation correctly for all cases.

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.

This patch defines a topology macro for ppc64, nr_cpus_node(node) which
returns the number of CPUs on 'node'.  This patch also adds code to compute
and store these values in an array for quick lookup.

sched_best_cpu schedules processes on nodes based on node_nr_running.  For
CPU-less nodes, this is always 0, and thus sched_best_cpu tends to migrate
tasks to these nodes, which eventually get remigrated elsewhere.

This patch adds include/linux/topology.h, and modifies all includes of
asm/topology.h to linux/topology.h.  A subsequent patch in this series adds
helper functions to linux/topology.h to ensure processes are only migrated
to nodes with CPUs.

Apparently this BUG is triggerable due to correct and expected events.
