053837fce7 [PATCH] mm: migration page refcounting fix
Migration code currently does not take a reference to target page
properly, so between unlocking the pte and trying to take a new
reference to the page with isolate_lru_page, anything could happen to
it.

Fix this by holding the pte lock until we get a chance to elevate the
refcount.

Other small cleanups while we're here.

e236a166b2 [PATCH] mm: dirty_exceeded speedup
Ravikiran reports that this variable is bouncing all around nodes on NUMA
machines, causing measurable performance problems.  Fix that up by only
writing to it when it actually changed.

And put it in a new cacheline to prevent it sharing with other things (this
happened).

c2aeacd48c [PATCH] Prevent trident driver from grabbing pcnet32 hardware
Some pcnet32 hardware erroneously has the Vendor ID for Trident.  The
pcnet32 driver looks for the PCI ethernet class before grabbing the
hardware, but the current trident driver does not check against the PCI
audio class.  This allows the trident driver to claim the pcnet32 hardware.
 This patch prevents that.

This revised version of the OSS Trident patch includes PCI_DEVICE Macro
usage.

ad12583f46 [IPV4]: Fix multiple bugs in IGMPv3
1) fix "mld_marksources()" to
        a) send nothing when all queried sources are excluded
        b) send full exclude report when source queried sources are
                not excluded
        c) don't schedule a timer when there's nothing to report

2) fix "add_grec()" to send empty-source records when it should
        The original check doesn't account for a non-empty source
        list with all sources inactive; the new code keeps that
        short-circuit case, and also generates the group header
        with an empty list if needed.

3) fix mca_crcount decrement to be after add_grec(), which needs
        its original value

4) add/remove delete records and prevent current advertisements
        when an exclude-mode filter moves from "active" to "inactive"
        or vice versa based on new filter additions.

        Items 1-3 are just IPv4 versions of the IPv6 bugs found
by Yan Zheng and fixed earlier. Item #4 is a related bug that
affects exclude-mode change records only (but not queries) and
also occurs in IPv6 (IPv6 version coming soon).

	I/O ports at e880 [size=128]
	I/O ports at e400 [size=256]

It has two 16550A, and is not listed in kernel, although the
manufacturer clams that it is supported...

c6b3feaf57 [PATCH] Fix sparse parse error in lppaca.h
sparse can't parse a struct definition in include/asm-powerpc/lppaca.h,
even though gcc can accept it.  The form looks like this:

        struct __attribute__((whatever)) foo { };

An equivalent that both gcc and sparse can handle is

        struct foo { } __attribute__((whatever));

This is the only definition of this type in the tree, and fixing it is
easier than fixing sparse.

Signed-off-by: Bryan O'Sullivan <bos@serpentine.com>
[ Side note: fixing sparse wouldn't be hard, but the "attribute at the
  end" version is the canonical one, and the one that makes sense. So
  let's just fix the kernel instead. Luc Van Oostenryck already sent
  out a sparse patch to the sparse mailing list in case anybody cares.
