This reverts commit 73d4066055e0e2830533041f4b91df8e6e5976ff.
Martin Steigerwald reported that this change caused a hard lockup when
using USB if threadirqs are enabled. Thomas pointed out that this patch
is incorrect, and can cause problems. So revert it to get the
previously working functionality back.

Commit f79b2d0f (USB: keyspan: fix NULL-pointer dereferences and

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
* Don't show scripts menu for 'perf top', fix from Feng Tang
* Add framework for automated perf_event_attr tests, where tools with
different command line options will be run from a 'perf test', via
python glue, and the perf syscall will be intercepted to verify that
the perf_event_attr fields set by the tool are those expected,
from Jiri Olsa
* Use normalized arch name for searching objdump path. This fixes cases
where the system's objdump (e.g. x86_64) supports the architecture in
the perf.data file (e.g. i686), but is not the same,
fix from Namhyung Kim.
* Postpone objdump check until annotation requested, from Namhyung Kim.
* Add a 'link' method for hists, so that we can have the leader with
buckets for all the entries in all the hists. This new method
is now used in the default 'diff' output, making the sum of the 'baseline'
column be 100%, eliminating blind spots. Now we need to use this
for 'diff' with > 2 perf.data files and for multi event 'report' and
'annotate'.
* libtraceevent fixes for compiler warnings trying to make perf it build
on some distros, like fedora 14, 32-bit, some of the warnings really
pointed to real bugs.
* Remove temp dir on failure in 'perf test', fix from Jiri Olsa.
* Fixes for handling data, stack mmaps, from Namhyung Kim.
* Fix live annotation bug related to recent objdump lookup patches, from
Namhyung Kim
* Don't try to follow jump target on PLT symbols in the annotation browser,

The CBUS UART's interrupt number was wrong conflicting with the interrupt
being tied to the Intel PIIX4. Since the PIIX4's interrupt is registered
before the CBUS UART which is not being used on most systems this would
not be noticed.
Attempts to open the ttyS2 CBUS UART would result in:
genirq: Flags mismatch irq 18. 00000000 (serial) vs. 00010000 (XT-PIC cascade)
serial_link_irq_chain: request failed: -16 for irq: 18

Select HAVE_ALIGNED_STRUCT_PAGE on s390, so that the slub allocator can make
use of compare and swap double for lockless updates. This increases the size
of struct page to 64 bytes (instead of 56 bytes), however the performance gain
justifies the increased size:
- now excactly four struct pages fit into a single cache line; the
case that accessing a struct page causes two cache line loads
does not exist anymore.
- calculating the offset of a struct page within the memmap array
is only a simple shift instead of a more expensive multiplication.
A "hackbench 200 process 200" run on a 32 cpu system did show an 8% runtime
improvement.

access_ok() returns always "true" on s390. Therefore all access_ok()
invocations are rather pointless.
However when walking page tables we need to make sure that everything
is within bounds of the ASCE limit of the task's address space.
So remove the access_ok() call and add the same check we have in
get_user_pages_fast().

So check against TASK_SIZE (which is the ASCE limit) before

QEMU first retrieves the supported features via KVM_GET_SUPPORTED_CPUID
and then sets them later. So guest's X86_FEATURE_XSAVE should be masked
out on hosts without X86_FEATURE_XSAVE, making kvm_set_cr4 with
X86_CR4_OSXSAVE fail. Userspaces that allow specifying guest cpuid with
X86_FEATURE_XSAVE even on hosts that do not support it, might be
susceptible to this attack from inside the guest as well.
Allow setting X86_CR4_OSXSAVE bit only if host has XSAVE support.

XHCI patches from Sarah:
"xHCI patches for 3.8
Hi Greg,
Here's some xHCI bug fixes. There's nothing major in here that can't
wait for 3.8. The NULL pointer deref that commit 68e5254 fixes hasn't
ever been reported in the three years that the xHCI driver has been
available, so it can wait a few more weeks.
There's two quirk updates, one for Fresco Logic (commit bba18e3) and one
for xHCI hosts with the TI redriver (commit b0e4e60). Commit 4525c0a
makes the xHCI driver work correctly on the SiBridge xHCI host (and
perhaps other 1.0 xHCI host controllers). Commit 392a07a fixes a bug in
the Intel Panther Point xHCI host bandwidth checking checking.
Commits 2611bd1 and 77b8476 are trivial cleanup patches.
Sarah Sharp"

On OMAP4 boards using the TWL6030 PMIC, the sys_drm_msecure is
connected to the MSECURE input of the TWL6030 PMIC. This signal
controls the secure-mode operation of the PMIC. If its not mux'd
correctly, some functionality of the PMIC will not be accessible since
the PMIC will be in secure mode.
For example, if the TWL RTC is in secure mode, most of its registers
are read-only, meaning (re)programming the RTC (e.g. for wakeup from
suspend) will fail.
To fix, ensure the signal is properly mux'd as output when TWL is
intialized.
This fix is required when using recent versions of u-boot (>= v2012.04.01)
since u-boot is no longer setting the default mux for this pin.

Ali reports that plugging a device into the Fresco Logic xHCI host with
PCI device ID 1400 produces an IRQ error:
do_IRQ: 3.176 No irq handler for vector (irq -1)
Other early Fresco Logic host revisions don't support MSI, even though
their PCI config space claims they do. Extend the quirk to disabling
MSI to this chipset revision. Also enable the short transfer quirk,
since it's likely this revision also has that quirk, and it should be
harmless to enable.

xhci_alloc_segments_for_ring() builds a list of xhci_segments and links
the tail to head at the end (forming a ring). When it bails out for OOM
reasons half-way through, it tries to destroy its half-built list with
xhci_free_segments_for_ring(), even though it is not a ring yet. This
causes a null-pointer dereference upon hitting the last element.
Furthermore, one of its callers (xhci_ring_alloc()) mistakenly believes
the output parameters to be valid upon this kind of OOM failure, and
calls xhci_ring_free() on them. Since the (incomplete) list/ring should
already be destroyed in that case, this would lead to a use after free.
This patch fixes those issues by having xhci_alloc_segments_for_ring()
destroy its half-built, non-circular list manually and destroying the
invalid struct xhci_ring in xhci_ring_alloc() with a plain kfree().
This patch should be backported to kernels as old as 2.6.31, that
contains the commit 0ebbab37422315a5d0cb29792271085bafdf38c0 "USB: xhci:

A separate patch will need to be developed for kernels older than 3.4,
since the ring allocation code was refactored in that kernel.

The xHCI 1.0 specification made a change to the TD Size field in TRBs.
The value is now the number of packets that remain to be sent in the TD,
not including this TRB. The TD Size value for the last TRB in a TD must
always be zero.
The xHCI function xhci_v1_0_td_remainder() attempts to calculate this,
but it gets it wrong. First, it erroneously reuses the old
xhci_td_remainder function, which will right shift the value by 10. The
xHCI 1.0 spec as of June 2011 says nothing about right shifting by 10.
Second, it does not set the TD size for the last TRB in a TD to zero.
Third, it uses roundup instead of DIV_ROUND_UP. The total packet count
is supposed to be the total number of bytes in this TD, divided by the
max packet size, rounded up. DIV_ROUND_UP is the right function to use
in that case.
With the old code, a TD on an endpoint with max packet size 1024 would
be set up like so:
TRB 1, TRB length = 600 bytes, TD size = 0
TRB 1, TRB length = 200 bytes, TD size = 0
TRB 1, TRB length = 100 bytes, TD size = 0
With the new code, the TD would be set up like this:
TRB 1, TRB length = 600 bytes, TD size = 1
TRB 1, TRB length = 200 bytes, TD size = 1
TRB 1, TRB length = 100 bytes, TD size = 0

David reports that at drivers/usb/host/xhci.c:2257:
static bool xhci_is_sync_in_ep(unsigned int ep_type)
{
return (ep_type == ISOC_IN_EP || ep_type != INT_IN_EP);
}
The static analyser cppcheck says
[linux-3.7-rc2/drivers/usb/host/xhci.c:2257]: (style) Redundant condition: If ep_type == 5, the comparison ep_type != 7 is always true.
Maybe the original programmer intention was something like
static bool xhci_is_sync_in_ep(unsigned int ep_type)
{
return (ep_type == ISOC_IN_EP || ep_type == INT_IN_EP);
}
Fix this.
This patch should be backported to stable kernels as old as 3.2, that
contain the commit 2b69899934c63b7b9432568584fb4c4a2924f40c "xhci: USB
3.0 BW checking."

Non-static xHCI driver symbols should start with the "xhci_" prefix, in
order to avoid namespace pollution. Rename the "handshake" function to
"xhci_handshake".

Any failures in intel_sdvo_init() after the intel_sdvo_setup_output() call
left behind ghost connectors, attached (with a dangling pointer) to the
sdvo that has been cleaned up and freed. Properly destroy any connectors
attached to the encoder.

Sankara reported that the genirq core code fails to adjust the
affinity of an interrupt thread in several cases:
1) On request/setup_irq() the call to setup_affinity() happens before
the new action is registered, so the new thread is not notified.
2) For secondary shared interrupts nothing notifies the new thread to
change its affinity.
3) Interrupts which have the IRQ_NO_BALANCE flag set are not moving
the thread either.
Fix this by setting the thread affinity flag right on thread creation
time. This ensures that under all circumstances the thread moves to
the right place. Requires a check in irq_thread_check_affinity for an
existing affinity mask (CONFIG_CPU_MASK_OFFSTACK=y)

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren <tony@atomide.com>:
This series fixes an annoying regression to make MUSB working
on omap4 again. Although it's getting rather late for these
changes for the -rc cycle, it is important as many devices
are using MUSB for charging and connectivity.
With the USB PHY changes, MUSB started using the newly added
drivers/usb/phy/omap-usb2.c driver introduced by commit
657b306a (usb: phy: add a new driver for omap usb2 phy)
that is using the newly introduced drivers/bus/omap-ocp2scp.c
introduced by commit 26a84b3e (drivers: bus: add a new driver
for omap-ocp2scp).
These changes allowed dropping a lot of PHY related code from
arch/arm/mach-omap2/omap_phy_internal.c and have it live in
the device driver like it should with commit c9e4412a (arm: omap:
phy: remove unused functions from omap-phy-internal.c).
However, MUSB on omap4 broke with these changes for legacy
platform data boot, and now only works with device tree for
omap4. Unfortunately we are still few critical bindings away
from being able to make omap4 usbale with device tree.
Fix the regression properly by adding platform data support
to the ocp2scp driver so we can avoid adding back the driver
code to arch/arm/mach-omap2.

When in world roaming mode, allow 40 MHz to be used
on channels 12 and 13 so that an AP that is, e.g.,
using HT40+ on channel 9 (in the UK) can be used.
