During test busn_res allocation with cardbus, found pci card removal is not
working anymore, and it turns out it is broken by:
|commit 79cc9601c3e42b4f0650fe7e69132ebce7ab48f9
|Date: Tue Nov 22 21:06:53 2011 -0800

| PCI: Only call pci_stop_bus_device() one time for child devices at remove
The above changed the behavior of pci_remove_behind_bridge that
yenta_cardbus depended on. So restore the old behavoir of
pci_remove_behind_bridge (which requires stopping and removing of all
devices) by:
1. rename pci_remove_behind_bridge to __pci_remove_behind_bridge, and let
__pci_remove_bus_device() call it instead.
2. add pci_stop_behind_bridge that will stop devices behind a bridge
3. add back pci_remove_behind_bridge that will stop and remove devices
under bridge.
-v2: update commit description a little bit.

Commit 653241 (net: RFC3069, private VLAN proxy arp support) changed
the behavior of arp proxy to send arp replies back out on the interface
the request came in even if the private VLAN feature is disabled.
Previously we checked rt->dst.dev != skb->dev for in scenarios, when
proxy arp is enabled on for the netdevice and also when individual proxy
neighbour entries have been added.
This patch adds the check back for the pneigh_lookup() scenario.

This patch fix a bug which introduced by commit ac8a4810 (ipv4: Save
nexthop address of LSRR/SSRR option to IPCB.).In that patch, we saved
the nexthop of SRR in ip_option->nexthop and update iph->daddr until
we get to ip_forward_options(), but we need to update it before
ip_rt_get_source(), otherwise we may get a wrong src.

When the netprio_cgroup module is not loaded, net_prio_subsys_id
is -1, and so sock_update_prioidx() accesses cgroup_subsys array
with negative index subsys[-1].
Make the code resembles cls_cgroup code, which is bug free.

So we delay the allocation till the priority is set through cgroup,
and this makes skb_update_priority() faster when it's not set.
This also eliminates an off-by-one bug similar with the one fixed

For an SRIOV device, PCI_SRIOV_SYS_PGSIZE should be set before
the PCI_SRIOV_BAR are queried. The sys pagesize defaults to 4k,
so this change is required on powerpc box with 64k base page size.
This is a regression caused due to moving SRIOV init to sriov_enable().

Fixes PCI device detection on IBM xSeries IBM 3850 M2 / x3950 M2
when using ACPI resources (_CRS).
This is default, a manual workaround (without this patch)
would be pci=nocrs boot param.
V2: Add dev_warn if the workaround is hit. This should reveal
how common such setups are (via google) and point to possible
problems if things are still not working as expected.

Stop reusing dquots from the freelist when allocating new ones directly, and
implement a shrinker that actually follows the specifications for the
interface. The shrinker implementation is still highly suboptimal at this
point, but we can gradually work on it.
This also fixes an bug in the previous lock ordering, where we would take
the hash and dqlist locks inside of the freelist lock against the normal
lock ordering. This is only solvable by introducing the dispose list,
and thus not when using direct reclaim of unused dquots for new allocations.
As a side-effect the quota upper bound and used to free ratio values in
/proc/fs/xfs/xqm are set to 0 as these values don't make any sense in the
new world order.

The drm core _really_ likes to frob around with the crtc timings and
put halfed vertical timings (in fields) in there. Which confuses the
overlay code, resulting in it's refusal to display anything at the
lower half of an interlaced pipe.

The hw seems to use this to correctly insert the required delay
before/after an even/odd interlaced field. This might also explain
why we need to substract 1 half-line from vtotal - if the hw just
adds the delay programmend in VSYNCSHIFT the total frame time would be
about that too long.
These registers seems to only exist on gen4 and later. For paranoia
also program it to 0 for progressive modes, but according to
documentation the hw should just ignore it in this case.

gen2 doesn't support it, so be a bit more paranoid and add a check to
ensure that we never ever set an unsupported interlaced bit.
Ensure that userspace can't set an interlaced mode by resetting
interlace_allowed for the crt on gen2. dvo and lvds are the only other
encoders that gen2 supports and these already disallow interlaced
modes.

According to bspec, we need to subtract an additional line from vtotal
for interlaced modes and vblank_end needs to equal vtotal. All other
timing fields do not need this special treatment, so kill it.
Bspec says that this is irrespective of whether the interlaced mode
has an odd or even vtotal, both modes are supported.

We have a pretty decent confusion about vertical timings of interlaced
modes. Peter Ross has written a patch that makes interlace modes work
on a lot more platforms/output combinations by doubling the vertical
timings.
The issue with that patch is that core drm _does_ support specifying
whether we want these vertical timings in fields or frames, we just
haven't managed to consistently use this facility. The relavant
function is drm_mode_set_crtcinfo, which fills in the crtc timing
information.
The first thing to note is that the drm core keeps interlaced modes in
frames, but displays modelines in fields. So when the crtc modeset
helper copies over the mode into adjusted_mode it will already contain
vertical timings in half-frames. The result is that the fixup code in
intel_crtc_mode_fixup doesn't actually do anything (in most cases at
least).
Now gen3+ natively supports interlaced modes and wants the vertical
timings in frames. Which is what sdvo already fixes up, at least under
some conditions.
There are a few other place that demand vertical timings in fields
but never actually deal with interlaced modes, so use frame timings
for consistency, too. These are:
- lvds panel,
- dvo encoders - dvo is the only way gen2 could support interlaced
mode, but currently we don't support any encoders that do.
- tv out - despite that the tv dac sends out an interlaced signal it
expects a progressive mode pipe configuration.
All these encoders enforce progressive modes by resetting
interlace_allowed.
Hence we always want crtc vertical timings in frames. Enforce this in
our crtc mode_fixup function and rip out any redudant timing
computations from the encoders' mode_fixup function.
v2-4: Adjust the vertical timings a bit.
v5: Split out the 'subtract-one for interlaced' fixes.
v6: Clarify issues around tv-out and gen2.

- Clarify which bits are for which chips.
- Note that gen2 can't do interlaced directly (only via dvo tv chips).
- Move the mask to the top to make it clearer how wide this field is.
- Add defintions for all possible values.
This patch doesn't change any code.
v2: Paulo Zanoni pointed out that the pixel doubling modes do no
longer exist on ivb.

Back-merge from drm-fixes into drm-intel-next to sort out two things:
- interlaced support: -fixes contains a bugfix to correctly clear
interlaced configuration bits in case the bios sets up an interlaced
mode and we want to set up the progressive mode (current kernels
don't support interlaced). The actual feature work to support
interlaced depends upon (and conflicts with) this bugfix.
- forcewake voodoo to workaround missed IRQ issues: -fixes only enabled
this for ivybridge, but some recent bug reports indicate that we
need this on Sandybridge, too. But in a slightly different flavour
and with other fixes and reworks on top. Additionally there are some
forcewake cleanup patches heading to -next that would conflict with
currrent -fixes.

On OMAP2420-based systems, the PM code ignores the state of the UART
functional clocks when determining what idle state to enter. This
breaks the serial port now that the UART driver's clock behavior can
be controlled via the PM autosuspend timeout.
To fix, remove the special-case idle handling for the UARTs in the
OMAP2420/2430 PM idle code added by commit
4af4016c53f52b26461b8030211f8427a58fa5ed ("OMAP3: PM: UART: disable

Patchset "ARM: orion: Refactor the MPP code common in the orion
platform" broke at least Orion5x based platforms. These platforms have
pins configured as GPIO when the selector is not 0x0. However the
common code assumes the selector is always 0x0 for a GPIO lines. It
then ignores the GPIO bits in the MPP definitions, resulting in that
Orion5x machines cannot correctly configure there GPIO lines.
The Fix removes the assumption that the selector is always 0x0.
In order that none GPIO configurations are correctly blocked,
Kirkwood and mv78xx0 MPP definitions are corrected to only set the
GPIO bits for GPIO configurations.

and is rebased on v3.3-rc2.

otherwise the allmodconfig build fails on sparc64.

- Windows uses this on snb and later.
- We need the basic hw support to work before we can think about real
per-process address spaces and other cool features we want.
But Chris Wilson was complaining all over irc and intel-gfx that this
will blow up if we don't have a module option to disable it. Hence add
one, to prevent this.
ppgtt support seems to slightly change the timings and make crashy
things slightly more or less crashy. Now in my testing and the testing
this got on troublesome snb machines, it seems to have improved things
only. But on ivb it makes quite a few crashes happen much more often,
see
https://bugs.freedesktop.org/show_bug.cgi?id=41353
Luckily Eugeni Dodonov seems to have a set of workarounds that fix
this issue.
v2: Don't try to enable ppgtt on pre-snb.
v3: Pimp commit message and make Chris Wilson less grumpy by adding a
module option.
v4: New try at making Chris Wilson happy.

The current error handling doesn't work because we flash_part is a u32
so the checks for negative error codes don't work. I considered making
things signed but I don't know the hardware enough to say if that's a
problem. Really, we don't use the error codes so just returning zero
for all problems is fine.

We use len to store the return value from eth_header(). eth_header()
can return -ETH_HLEN (-14). We want to pass this back instead of
truncating it to 65522 and returning that.

This adds support to bind/unbind objects and wires it up. Objects are
only put into the ppgtt when necessary, i.e. at execbuf time.
Objects are still unconditionally put into the global gtt.
v2: Kill the quick hack and explicitly pass cache_level to ppgtt_bind
like for the global gtt function. Noticed by Chris Wilson.

This just adds the setup and teardown code for the ppgtt PDE and the
last-level pagetables, which are fixed for the entire lifetime, at
least for the moment.
v2: Kill the stray debug printk noted by and improve the pte
definitions as suggested by Chris Wilson.
v3: Clean up the aperture stealing code as noted by Ben Widawsky.
v4: Paint the init code in a more pleasing colour as suggest by Chris
Wilson.
v5: Explain the magic numbers noticed by Ben Widawsky.

We need this because ppgtt page directory entries need to be in the

read_lock(&tpt_trig->trig.leddev_list_lock) is accessed via the path
ieee80211_open (->) ieee80211_do_open (->) ieee80211_mod_tpt_led_trig
(->) ieee80211_start_tpt_led_trig (->) tpt_trig_timer before initializing
it.
the intilization of this read/write lock happens via the path
ieee80211_led_init (->) led_trigger_register, but we are doing
'ieee80211_led_init' after 'ieeee80211_if_add' where we
register netdev_ops.
so we access leddev_list_lock before initializing it and causes the
following bug in chrome laptops with AR928X cards with the following
script
while true

sudo modprobe -v ath9k

sudo modprobe -r ath9k

When trying to nf_queue GRO/GSO skbs, nf_queue uses skb_gso_segment
to split the skb.
However, if nf_queue is called via bridge netfilter, the mac header
won't be preserved -- packets will thus contain a bogus mac header.
Fix this by setting skb->data to the mac header when skb->nf_bridge
is set and restoring skb->data afterwards for all segments.
