With lots of virtual devices it's easy to generate a lot of

ab854b24a2 net: Teach pegasus driver to ignore bluetoother adapters with clashing Vendor:Product IDs
The Belkin F8T012xx1 bluetooth adaptor has the same vendor and product
IDs as the Belkin F5D5050, so we need to teach the pegasus driver to
ignore adaptors belonging to the "Wireless" class 0xE0. For this one
case anyway, seeing as pegasus is a driver for "Wired" adaptors.

71999d9862 x86/paravirt: Use normal calling sequences for irq enable/disable
Bastian Blank reported a boot crash with stackprotector enabled,
and debugged it back to edx register corruption.

For historical reasons irq enable/disable/save/restore had special
calling sequences to make them more efficient.  With the more
recent introduction of higher-level and more general optimisations
this is no longer necessary so we can just use the normal PVOP_
macros.

This fixes some residual bugs in the old implementations which left
edx liable to inadvertent clobbering. Also, fix some bugs in
__PVOP_VCALLEESAVE which were revealed by actual use.

b56ab33d68 eeepc-laptop: Prevent a panic when disabling RT2860 wireless when associated
This works around what I think is actually a bug in rt2860sta which is
triggered when the hardware "disappears" from beneath the driver, i.e. when
wireless is toggled off via ACPI. It does so by ensuring that the rfkill
soft-block flag is set before the hardware is disabled.

I do not know whether this patch is required if rt2800pci is in use instead
of rt2860sta; at the time of submission of this patch, I've not been able to
test this.

__init, and refers to a
function eeepc_hotk_add() which is non-init. Use __devinit for both

more appropriate and fixes a section mismatch warning.

497fb54f57 ACPI / PCI: Fix NULL pointer dereference in acpi_get_pci_dev() (rev. 2)
acpi_get_pci_dev() may be called for a non-PCI device, in which case
it should return NULL.  However, it assumes that every handle it
finds in the ACPI CA name space, between given device handle and the
PCI root bridge handle, corresponds to a PCI-to-PCI bridge with an
existing secondary bus.  For this reason, when it finds a struct
pci_dev object corresponding to one of them, it doesn't check if
its 'subordinate' field is a valid pointer.  This obviously leads to
a NULL pointer dereference if acpi_get_pci_dev() is called for a
non-PCI device with a PCI parent which is not a bridge.

To fix this issue make acpi_get_pci_dev() check if pdev->subordinate
is not NULL for every device it finds on the path between the root
bridge and the device it's supposed to get to and return NULL if the
"target" device cannot be found.

964f7e5a56 sh: force dcache flush if dcache_dirty bit set.
This too follows the ARM change, given that the issue at hand applies to
all platforms that implement lazy D-cache writeback.

This fixes up the case when a page mapping disappears between the
flush_dcache_page() call (when PG_dcache_dirty is set for the page) and
the update_mmu_cache() call -- such as in the case of swap cache being
freed early. This kills off the mapping test in update_mmu_cache() and
switches to simply testing for PG_dcache_dirty.

d20ef63d32 mac80211: document ieee80211_rx() context requirement
ieee80211_rx() must be called with softirqs disabled
since the networking stack requires this for netif_rx()
and some code in mac80211 can assume that it can not
be processing its own tasklet and this call at the same
time.

It may be possible to remove this requirement after a
careful audit of mac80211 and doing any needed locking
improvements in it along with disabling softirqs around
netif_rx(). An alternative might be to push all packet
processing to process context in mac80211, instead of
to the tasklet, and add other synchronisation.

51f98f1313 mac80211: fix ibss race
When a scan completes, we call ieee80211_sta_find_ibss(),
which is also called from other places. When the scan was
done in software, there's no problem as both run from the
single-threaded mac80211 workqueue and are thus serialised
against each other, but with hardware scan the completion
can be in a different context and race against callers of
this function from the workqueue (e.g. due to beacon RX).
So instead of calling ieee80211_sta_find_ibss() directly,
just arm the timer and have it fire, scheduling the work,
which will invoke ieee80211_sta_find_ibss() (if that is
appropriate in the current state).

787b2faadc ARM: force dcache flush if dcache_dirty bit set
On ARM, update_mmu_cache() does dcache flush for a page only if
it has a kernel mapping (page_mapping(page) != NULL). The correct
behavior would be to force the flush based on dcache_dirty bit only.

One of the cases where present logic would be a problem is when
a RAM based block device[1] is used as a swap disk. In this case,
we would have in-memory data corruption as shown in steps below:

do_swap_page()
{
    - Allocate a new page (if not already in swap cache)
    - Issue read from swap disk
        - Block driver issues flush_dcache_page()
        - flush_dcache_page() simply sets PG_dcache_dirty bit and does not
          actually issue a flush since this page has no user space mapping yet.
    - Now, if swap disk is almost full, this newly read page is removed
      from swap cache and corrsponding swap slot is freed.
    - Map this page anonymously in user space.
    - update_mmu_cache()
        - Since this page does not have kernel mapping (its not in page/swap
          cache and is mapped anonymously), it does not issue dcache flush
          even if dcache_dirty bit is set by flush_dcache_page() above.

    <user now gets stale data since dcache was never flushed>
}

Same problem exists on mips too.

 - brd (RAM based block device)
 - ramzswap (RAM based compressed swap device)

7a4b7e5e74 x86: Fix Suspend to RAM freeze on Acer Aspire 1511Lmi laptop
Move the trampoline and accessors back out of .cpuinit.* for the
case of 64-bits+ACPI_SLEEP.

This solves s2ram hangs reported in:

9a821b2316 x86: Move pci_iommu_init to rootfs_initcall()
We want this to happen after the PCI quirks, which are now running at
the very end of the fs_initcalls.

This works around the BIOS problems which were originally addressed by
commit db8be50c43 ('USB: Work around BIOS
bugs by quiescing USB controllers earlier'), which was reverted in
commit d93a8f829f.

cf6f3bf7e5 Run pci_apply_final_quirks() sooner.
Having this as a device_initcall() means that some real device drivers
can actually initialise _before_ the quirks are run, which is wrong.

We want it to run _before_ device_initcall(), but _after_ fs_initcall(),
since some arch-specific PCI initialisation like pcibios_assign_resources()
is done at fs_initcall().

We could use rootfs_initcall() but I actually want to use that for the
IOMMU initialisation, which has to come after the quirks, but still
before the real devices. So use fs_initcall_sync() instead -- since this
is entirely synchronous, it doesn't hurt that it'll escape the
synchronisation.

8d86fb2c80 Rename pci_init() to pci_apply_final_quirks(), move it to quirks.c
This function may have done more in the past, but all it does now is
apply the PCI_FIXUP_FINAL quirks. So name it sensibly and put it where
it belongs.

f8ebdff087 mfd: Fix twl4030 boot with twl4030 usb transceiver enabled
The usb regulator supplies (usb1v5, usb1v8 & usb3v1) must be available
before adding the twl4030_usb child, else twl4030_usb_ldo_init() will
always fail thus causing boot lock-up.

This patch fixes boot on OMAP systems using the twl4030 usb transceiver.

1a78cedb99 sparc64: Fix D-cache flushing on swapin from SW devices.
Thanks to tip form ARM folks and Russell King.

If flush_dcache_page() occurs on a swapin it will have a mapping
and we'll try to defer the flush by setting the dirty bit.

But when it hits update_dcache_page() we won't flush because the
page won't have a mapping any more.  So remove the mapping
requirement in flush_dcache().

The following htmldocs warnings:

  Warning(kernel/sched.c:685): No description found for parameter 'cpu'
  Warning(kernel/sched.c:3676): No description found for parameter 'sd'

Trigger because new parameters were added to update_rq_clock() and
update_group_power() without updating the kernel-doc notation.
