Line widgets had not been included in either the power up or power down
sequences so if a widget had an event associated with it that event would
never be run. Fix this minimally by adding them to the sequences, we
should probably be doing away with the specific widget types as they all
have the same priority anyway.

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.

Since commit 96104eda01 ("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.

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 3e1a7ff8a0, 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.

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.

for bitmap_daemon_work to run while the bitmap is being

This is particularly a problem if bitmap_daemon_work sees

We've been adding new mappings, but not destroying old mappings.
This can lead to a page leak as pages are pinned using
get_user_pages, but only unpinned with put_page if they still
exist in the memslots list on vm shutdown. A memslot that is
destroyed while an iommu domain is enabled for the guest will
therefore result in an elevated page reference count that is
never cleared.
Additionally, without this fix, the iommu is only programmed
with the first translation for a gpa. This can result in
peer-to-peer errors if a mapping is destroyed and replaced by a
new mapping at the same gpa as the iommu will still be pointing
to the original, pinned memory address.

This reverts commit b519508298.
The reason for this revert is that making the frequency verification
preemptible and interruptible is not working reliably. Michaels
machine failed to use PM-timer with the message:
PM-Timer running at invalid rate: 113% of normal - aborting.
That's not a surprise as the frequency verification does rely on
interrupts being disabled. With a async scheduled thread there is no
guarantee to achieve the same result. Also some driver might fiddle
with the CTC channel 2 during the verification period, which makes the
result even more random and unpredictable.
This can be solved by using the same mechanism as we use in the
deferred TSC validation code, but that only will work if we verified a
working HPET _BEFORE_ trying to do the PM-Timer lazy validation.
So for now reverting is the safe option.

Allow a v3 unchecked open of a non-regular file succeed as if it were a
lookup; typically a client in such a case will want to fall back on a
local open, so succeeding and giving it the filehandle is more useful
than failing with nfserr_exist, which makes it appear that nothing at
all exists by that name.
Similarly for v4, on an open-create, return the same errors we would on
an attempt to open a non-regular file, instead of returning
nfserr_exist.
This fixes a problem found doing a v4 open of a symlink with
O_RDONLY|O_CREAT, which resulted in the current client returning EEXIST.

The first case has the lock originating from within rtlwifi and could

within mac80211. The kmalloc() call is removed from _usb_read_sync()
by creating a ring buffer pointer in the private area and

This merges the 32- and 64-bit versions of the x86 strncpy_from_user()
by just rewriting it in C rather than the ancient inline asm versions
that used lodsb/stosb and had been duplicated for (trivial) differences
between the 32-bit and 64-bit versions.
While doing that, it also speeds them up by doing the accesses a word at
a time. Finally, the new routines also properly handle the case of
hitting the end of the address space, which we have never done correctly
before (fs/namei.c has a hack around it for that reason).
Despite all these improvements, it actually removes more lines than it
adds, due to the de-duplication. Also, we no longer export (or define)
the legacy __strncpy_from_user() function (that was defined to not do
the user permission checks), since it's not actually used anywhere, and
the user address space checks are built in to the new code.
Other architecture maintainers have been notified that the old hack in
fs/namei.c will be going away in the 3.5 merge window, in case they
copied the x86 approach of being a bit cavalier about the end of the
address space.
