Stop handling gpio-vbus internally. All boards that depended on this
functionality have been converted to use gpio-vbus tranceiver. All
new boards can use it right from the start. Drop unused code.

Use gpio_request_array() / gpio_free_array(), this makes the code
cleaner and less error prone.
This patch also properly frees GPIOs in case ata_host_activate() call fails.

This fixes a bug introduced by 807e8e40673d ("mmc: Fix sd/sdio/mmc
initialization frequency retries") that prevented SDIO drivers from
performing SDIO commands in their probe routines -- the above patch
called mmc_claim_host() before sdio_add_func(), which causes a deadlock
if an external SDIO driver calls sdio_claim_host().
Fix tested on an OLPC XO-1.75 with libertas on SDIO.

Early gen3 and gen2 chipset do not have the relaxed per-surface tiling
constraints of the later chipsets, so we need to check that the GTT
alignment is correct for the new tiling. If it is not, we need to

Andi Kleen narrowed his GPU hangs on his Sugar Bay (SNB desktop) rev 09
down to the use of GPU semaphores, and we already know that they appear
broken up to Huron River (mobile) rev 08. (I'm optimistic that disabling
GPU semaphores is simply hiding another bug by the latency and
side-effects of the additional device interaction it introduces...)
However, use of semaphores is a massive performance improvement... Only
as long as the system remains stable. Enable at your peril.

If a virtio-console device gets unplugged while a port is open, a
subsequent close() call on the port accesses vqs to free up buffers.
This can lead to a crash.
The buffers are already freed up as a result of the call to
unplug_ports() from virtcons_remove(). The fix is to simply not access
vq information if port->portdev is NULL.

Whilst the GT is powered down (rc6), writes to MMADDR are placed in a
FIFO by the System Agent. This is a limited resource, only 64 entries, of
which 20 are reserved for Display and PCH writes, and so we must take
care not to queue up too many writes. To avoid this, there is counter
which we can poll to ensure there are sufficient free entries in the
fifo.
"Issuing a write to a full FIFO is not supported; at worst it could
result in corruption or a system hang."

As it turns out, userspace already depends upon being able to enable
tiling on existing bo which it promises to be large enough for its
purposes i.e. it will not access beyond the end of the last full-tile

This driver causes hard lockups, when the active clock soure is jiffies.
The reason is that it loops with interrupts disabled waiting for a
timestamp to be reached by polling getnstimeofday(). Though with a
jiffies clocksource, when that code runs on the same CPU which is
responsible for updating jiffies, then we loop in circles for ever
simply because the timer interrupt cannot update jiffies. So both UP
and SMP can be affected.
There is no easy fix for that problem so make it depend on BROKEN for
now.

For some time is known that ASPM is causing troubles on r8169, i.e. make
device randomly stop working without any errors in dmesg.
Currently Tomi Leppikangas reports that system with r8169 device hangs
with MCE errors when ASPM is enabled:
https://bugzilla.redhat.com/show_bug.cgi?id=642861#c4
Lets disable ASPM for r8169 devices at all, to avoid problems with
r8169 PCIe devices at least for some users.

Commit e2f2a93b, "of/promtree: add package-to-path support to pdt"
changed dp->name from using the 'name' property to using
package-to-path. This fixed /proc/device-tree creation by eliminating
conflicts between names (the 'name' property provides names like
'battery', whereas package-to-path provides names like
'/foo/bar/battery@0', which we stripped to 'battery@0'). However, it
also breaks of_device_id table matching.
The fix that we _really_ wanted was to keep dp->name based upon
the name property ('battery'), but based dp->full_name upon
package-to-path ('battery@0'). This patch does just that.
This changes all users (except SPARC) of promtree to use the full
result from package-to-path for full_name, rather than stripping the
directory out. In practice, the strings end up being exactly the
same; this change saves time, code, and memory.
SPARC continues to use the existing build_path_component() code.
v2: combine two patches and revert of_pdt_node_name to original version
v3: use dp->phandle instead of passing around node
v4: warn/bail out for non-sparc archs if pkg2path is not set
v5: split of_pdt_build_full_name into sparc & non-sparc versions
v6: Pass NULL to pkg2path before buf gets assigned.
Drop check for pkg2path hook on each and every node.
v7: Don't BUG() when unable to get the full_path; create a
known-unique name instead.

as was done with the initial support for those devices (i.e. 82567LM-3,
