During modeset we have to disable the pipe to reconfigure its timings
and maybe its size. Userspace may have queued up command buffers that
depend upon the pipe running in a certain configuration and so the
commands may become confused across the modeset. At the moment, we use a
less than satisfactory kick-scanline-waits should the GPU hang during
the modeset. It should be more reliable to wait for the pending
operations to complete first, even though we still have a window for
userspace to submit a broken command buffer during the modeset.

On gen2 MI_EXE_FLUSH is actually an AGP flush bit and on gen3 marked as
reserved. On both it is documented as being must-be-zero. So obey the
documentation, and separate the gen2 flush into its own little routine
and share with gen3.
This means that we can rename the existing render_ring_flush() to
reflect the generation from which it first applies and remove the code
for handling earlier generations from it.
v2: Applies to gen3 as well
v3: Make it compile and improve the commit message.

As we need to manipulate our device structure and allocate queue a task,
it is no longer a simple atomic operation and cannot be performed along
the atomic modeset paths. Instead make sure that we disable FBC (which
must be therefore kept as a set of simple register writes) when
performing the atomic modeset and leave the heavy-weight
intel_update_fbc() for the normal modeset.

This originally started as a patch from Bernard as a way of simply
setting the VS scheduler. After submitting the RFC patch, we decided to
also modify the DS scheduler. To be most explicit, I've made the patch
explicitly set all scheduler modes, and included the defines for other
modes (in case someone feels frisky later).
The rest of the story gets a bit weird. The first version of the patch
showed an almost unbelievable performance improvement. Since rebasing my
branch it appears the performance improvement has gone, unfortunately.
But setting these bits seem to be the right thing to do given that the
docs describe corruption that can occur with the default settings.
In summary, I am seeing no more perf improvements (or regressions) in my
limited testing, but we believe this should be set to prevent rendering
corruption, therefore cc stable.
v1: Clear bit 4 also (Ken + Eugeni)
Do a full clear + set of the bits we want (Me).

The (2<<6) virtual memory space selector harks back to gen3 and is
mandatory given our use of GTT space for batchbuffers. On gen4+, use of
the GTT became mandatory and bit6 marked reserved. However the code must
now explicitly set (1<<7), which conveniently is also (2<<6).
To clarify the meaning for future readers, replace the open coded (2<<6)
with MI_BATCH_GTT.

When the PCH split occurred, hw dropped support for separate hsync and
vsync disable in the VGA DAC. So add a PCH specific DPMS function that
just uses the port enable bit for controlling DPMS states.
Before this fix, when anything other than a full DPMS off occurred,
the VGA port would be left enabled and scanning out while all the other
heads would turn off as expected.

Semantically, rt6_clean_expires() wants to do rt->dst.from = NULL instead of
rt->dst.expires = 0. It is clearing the RTF_EXPIRES flag, so the union is going

Commit 1716a961 (ipv6: fix problem with expired dst cache) broke PMTU
discovery. rt6_update_expires() calls dst_set_expires(), which only updates
dst->expires if it has not been set previously (expires == 0) or if the new
expires is earlier than the current dst->expires.
rt6_update_expires() needs to zero rt->dst.expires, otherwise it will contain
ivalid data left over from rt->dst.from and will confuse dst_set_expires().

At the start of the function we assign 'a->d' to 'ap'. Then we use the
RESIZE_IF_NEEDED macro on 'a' - this may free 'a->d' and replace it
with newly allocaetd storage. In that case, we'll be operating on
freed memory further down in the function when we index into 'ap[]'.
Since we don't actually need 'ap' until after the use of the
RESIZE_IF_NEEDED macro we can just delay the assignment to it until
after we've potentially resized, thus avoiding the issue.
While I was there anyway I also changed the integer variable 'n' to be
const. It might as well be since we only assign to it once and use it
as a constant, and then the compiler will tell us if we ever assign to
it in the future.

This patch (as1542) changes the criterion ehci-hcd uses to tell when
it needs to resume the controller's root hub. A resume is needed when
a port status change is detected, obviously, but only if the root hub
is currently suspended.
Right now the driver tests whether the root hub is running, and that
is not the correct test. In particular, if the controller has died
then the root hub should not be restarted. In addition, some buggy
hardware occasionally requires the root hub to be running and
sending out SOF packets even while it is nominally supposed to be
suspended.
In the end, the test needs to be changed. Rather than checking whether
the root hub is currently running, the driver will now check whether
the root hub is currently suspended. This will yield the correct
behavior in all cases.

This patch (as154) fixes a self-deadlock that occurs when userspace
writes to the bConfigurationValue sysfs attribute for a hub with
children. The task tries to lock the bandwidth_mutex at a time when
it already owns the lock:
The attribute's method calls usb_set_configuration(),
which calls usb_disable_device() with the bandwidth_mutex
held.
usb_disable_device() unregisters the existing interfaces,
which causes the hub driver to be unbound.
The hub_disconnect() routine calls hub_quiesce(), which
calls usb_disconnect() for each of the hub's children.
usb_disconnect() attempts to acquire the bandwidth_mutex
around a call to usb_disable_device().
The solution is to make usb_disable_device() acquire the mutex for
itself instead of requiring the caller to hold it. Then the mutex can
cover only the bandwidth deallocation operation and not the region
where the interfaces are unregistered.
This has the potential to change system behavior slightly when a
config change races with another config or altsetting change. Some of
the bandwidth released from the old config might get claimed by the
other config or altsetting, make it impossible to restore the old
config in case of a failure. But since we don't try to recover from
config-change failures anyway, this doesn't matter.
[This should be marked for stable kernels that contain the commit
fccf4e86200b8f5edd9a65da26f150e32ba79808 "USB: Free bandwidth when
usb_disable_device is called."
That commit was marked for stable kernels as old as 2.6.32.]

This patch makes it so that we identify FCoE rings earlier than
ixgbe_set_rx_buffer_len. Instead we identify the Rx FCoE rings at
allocation time in ixgbe_alloc_q_vector.
The motivation behind this change is to avoid memory corruption when FCoE
is enabled. Without this change we were initializing the rings at 0, and
2K on systems with 4K pages, then when we bumped the buffer size to 4K with
order 1 pages we were accessing offsets 2K and 6K instead of 0 and 4K.
This was resulting in memory corruptions.

DMTIMER source selection on OMAP1 is broken. omap1_dm_timer_set_src()
tries to use __raw_{read,write}l() to read from and write to physical
addresses, but those functions take virtual addresses.
sparse caught this:
arch/arm/mach-omap1/timer.c:50:13: warning: incorrect type in argument 1 (different base types)
arch/arm/mach-omap1/timer.c:50:13: expected void const volatile [noderef] <asn:2>*<noident>

arch/arm/mach-omap1/timer.c:52:9: expected void const volatile [noderef] <asn:2>*<noident>
arch/arm/mach-omap1/timer.c:52:9: got unsigned int
Fix by using omap_{read,writel}(), just like the other users of the
MOD_CONF_CTRL_1 register in the OMAP1 codebase. Of course, in the long term,
removing omap_{read,write}l() is the appropriate thing to do; but
this will take some work to do this cleanly.
Looks like this was caused by 97933d6 (ARM: OMAP1: dmtimer: conversion

The current serial UART code, while fidling with ocp idlemode bits,
forget about the smart idle wakeup bit even if it is supported by
UART IP block. This will lead to missing the module wakeup on OMAP's
where the smart idle wakeup is supported.
This was the root cause of the console sluggishness issue, I have been
observing on OMAP4 devices and also can be potential reason for some
other UART wakeup issues.
