Hi Greg,
Here's 11 xHCI bug fixes for 3.4.
Some of the patches fix issues with crashes on system resume related to
VIA xHCI host controllers accessing bad memory addresses. The patches
change the register restore ordering, so I had several vendors confirm
that the patches don't break their xHCI hosts.
Elric Fu confirms this patchset fixes the VIA issue, Alex He confirms
the changes does not break suspend/resume on AMD xHCI systems, and I've
made sure it doesn't break Intel host controllers. I have not heard
back from Felipe about the TI host, so at this point, I'm just going to
send them off.
Several of the patches are marked for stable. Please pull.

In case the perf_session__process_event function fails, we estimate the
next event offset.
This is not necessary for sample event failing on unknown ID or machine.
In such case we know proper size of the event, so we dont need to guess.
Also failure statistics are updated correctly so we don't miss any
information.
Forcing perf_session__process_event to return 0 in case of unknown ID or
machine.

Since commit 96104eda0169 ("RDMA/core: Add SRQ type field"), kernel
users of SRQs need to specify srq_type = IB_SRQT_BASIC in struct
ib_srq_init_attr, or else most low-level drivers will fail in
when srpt_add_one() calls ib_create_srq() and gets -ENOSYS.
(mlx4_ib works OK nearly all of the time, because it just needs
srq_type != IB_SRQT_XRC. And apparently nearly everyone using
ib_srpt is using mlx4 hardware)

This patch (as1539) fixes a minor bug in the mass-storage gadget
drivers. When an unknown command is received, the error code sent
back is "Invalid Field in CDB" rather than "Invalid Command". This is
because the bitmask of CDB bytes allowed to be nonzero is incorrect.
When handling an unknown command, we don't care which command bytes
are nonzero. All the bits in the mask should be set, not just eight
of them.

Commit 9ad63986c606 (pda_power: Add support for using otg transceiver events)
converted the pda-power driver to use otg events to determine the status
of the power supply.
As gpio-vbus didn't use otg events until now, this change breaks setups
of pda-power with a gpio-vbus transceiver.
This patch adds the necessary otg events and notifiers to gpio-vbus.

The current virtio block's naming algorithm just supports 18278
(26^3 + 26^2 + 26) disks. If there are more virtio blocks,
there will be disks with the same name.
Based on commit 3e1a7ff8a0a7b948f2684930166954f9e8e776fe, add
a function "virtblk_name_format()" for virtio block to support mass
of disks naming.
Notes:
- Our naming scheme is ugly. We are stuck with it
for virtio but don't use it for any new driver:
new drivers should name their devices PREFIX%d
where the sequence number can be allocated by ida
- sd_format_disk_name has exactly the same logic.
Moving it to a central place was deferred over worries
that this will make people keep using the legacy naming
in new drivers.
We kept code idential in case someone wants to deduplicate later.

This fixes a resume regression introduced in
commit 7dd4906586274f3945f2aeaaa5a33b451c3b4bba

drm/i915: Mark untiled BLT commands as fenced on gen2/3
which fixed fencing tracking for untiled blt commands.
A side effect of that patch was that now also untiled objects have a
non-zero obj->last_fenced_seqno to track when a fence can be set up
after a pipelined tiling change. Unfortunately this was only cleared
by the fence setup and teardown code, resulting in tons of untiled but
inactive objects with non-zero last_fenced_seqno.
Now after resume we completely reset the seqno tracking, both on the
driver side (by setting dev_priv->next_seqno = 1) and on the hw side
(by allocating a new hws page, which contains the seqnos). Hilarity
and indefinite waits ensued from the stale seqnos in
obj->last_fenced_seqno from before the suspend.
The fix is to properly clear the fencing tracking state like we
already do for the normal gpu rendering while moving objects off the
active list.

This patch replaces the old global setting of irq_virq_count that is only
used by the NOMAP mapping and instead uses a revmap_data property so that
the maximum NOMAP allocation can be set per NOMAP irq_domain.
There is exactly one user of irq_virq_count in-tree right now: PS3.
Also, irq_virq_count is only useful for the NOMAP mapping. So,
instead of having a single global irq_virq_count values, this change
drops it entirely and added a max_irq argument to irq_domain_add_nomap().
That makes it a property of an individual nomap irq domain instead of
a global system settting.

If a bitmap is added while the array is active, it is possible
for bitmap_daemon_work to run while the bitmap is being
initialised.
This is particularly a problem if bitmap_daemon_work sees
bitmap->filemap as non-NULL before it has been filled in properly.
So hold bitmap_info.mutex while filling in ->filemap
to prevent problems.
This patch is suitable for any -stable kernel, though it might not
apply cleanly before about 3.1.

Inverting the quirk flag to indicate Tx-alignment. This aligns it with
the similar Rx-side quirk.
The call to wl1271_set_block_size() decides whether SDIO block size
alignment can be used or not. In case we're using SPI, we can't use
the block size alignment, so the function returns false. So we set
the quirk when wl1271_set_block_size() returns true and let the wl12xx
lower driver unset the bit for wl127x (since it doesn't support this
quirk).
