7c8ee9a863 [PATCH] mm: simplify vmscan vs release refcounting
The VM has an interesting race where a page refcount can drop to zero, but it
is still on the LRU lists for a short time.  This was solved by testing a 0->1
refcount transition when picking up pages from the LRU, and dropping the
refcount in that case.

Instead, use atomic_add_unless to ensure we never pick up a 0 refcount page
from the LRU, thus a 0 refcount page will never have its refcount elevated
until it is allocated again.

46453a6e19 [PATCH] mm: never ClearPageLRU released pages
If vmscan finds a zero refcount page on the lru list, never ClearPageLRU
it.  This means the release code need not hold ->lru_lock to stabilise
PageLRU, so that lock may be skipped entirely when releasing !PageLRU pages
(because we know PageLRU won't have been temporarily cleared by vmscan,
which was previously guaranteed by holding the lock to synchronise against
vmscan).

b40607fc02 [PATCH] __get_page_state() cpumask cleanup and fix
__get_page_state() has an open-coded for_each_cpu_mask() loop in it.

Tidy that up, then notice that the code was buggy:

	while (cpu < NR_CPUS) {
		unsigned long *in, *out, off;

		if (!cpu_isset(cpu, *cpumask))
			continue;

an obvious infinite loop.  I guess we just never call it with a holey cpu
mask.

Even after my cpumask size-reduction work, this patch increases code size :(

5e7a99ac45 [PATCH] v9fs: assign dentry ops to negative dentries
If a file is not found in v9fs_vfs_lookup, the function creates negative
dentry, but doesn't assign any dentry ops.  This leaves the negative entry
in the cache (there is no d_delete to mark it for removal).  If the file is
created outside of the mounted v9fs filesystem, the file shows up in the
directory with weird permissions.

This patch assigns the default v9fs dentry ops to the negative dentry.

9430d58e34 [PATCH] sched: remove sleep_avg multiplier
Remove the sleep_avg multiplier.  This multiplier was necessary back when
we had 10 seconds of dynamic range in sleep_avg, but now that we only have
one second, it causes that one second to be compressed down to 100ms in
some cases.  This is particularly noticeable when compiling a kernel in a
slow NFS mount, and I believe it to be a very likely candidate for other
recently reported network related interactivity problems.

In testing, I can detect no negative impact of this removal.

with #if's and #ifdef's.  This has many advantages such as allowing the
compiler to validate the syntax of the whole code, making it cleaner and
easier to understand, and ultimately allowing people to define
configuration symbols in terms of variables if they really want to
dynamically support multiple bus configurations at the same time (with
the unavoidable performance cost).

c3da144740 [PATCH] skge: check the allocation of ring buffer
The SysKonnect Genesis and Yukon chip sets have restrictions on the possible
control block area.  The memory needs to not cross 4 Gig boundary, and it needs
to be 8 byte aligned.  This patch checks and fails to bring the device up
if region is unacceptable.

cfc3ed796e [PATCH] skge: use auto masking of irqs
Improve performance of skge driver by not touching irq mask
register as much. Since the interrupt source auto-masks, the driver
can just leave it disabled until the end of the soft irq.
