Pull powerpc updates from Ben Herrenschmidt:
"Here's the powerpc batch for this merge window. Some of the
highlights are:
- A bunch of endian fixes ! We don't have full LE support yet in that
release but this contains a lot of fixes all over arch/powerpc to
use the proper accessors, call the firmware with the right endian
mode, etc...
- A few updates to our "powernv" platform (non-virtualized, the one
to run KVM on), among other, support for bridging the P8 LPC bus
for UARTs, support and some EEH fixes.
- Some mpc51xx clock API cleanups in preparation for a clock API
overhaul
- A pile of cleanups of our old math emulation code, including better
support for using it to emulate optional FP instructions on
embedded chips that otherwise have a HW FPU.
- Some infrastructure in selftest, for powerpc now, but could be
generalized, initially used by some tests for our perf instruction
counting code.
- A pile of fixes for hotplug on pseries (that was seriously
bitrotting)
- The usual slew of freescale embedded updates, new boards, 64-bit
hiberation support, e6500 core PMU support, etc..."

In usb_reset_and_verify_device(), hub_port_init() allocates a new bos
descriptor to hold the value read by the device. The new bos descriptor
has to be compared with the old one in order to figure out if device 's
firmware has changed in which case the device has to be reenumerated.
In the original code, none of the two descriptors was deallocated leading
to memory leaks.
This patch compares the old bos descriptor with the new one to detect change
in firmware and releases the newly allocated bos descriptor to prevent memory
leak.

xhci: Fix build breakage and new warnings.
Hi Greg,
This first patch should fix the build breakage Sedat Dilek reported.
Apologizes for not including this patch before commit
0730d52a86 "xhci:prevent "callbacks suppressed"
when debug is not enabled"
The second patch fixes a new build warning introduced by commit
c8476fb855 "usb: xhci: Disable runtime PM suspend
for quirky controllers", which was caught by the 0day build system.
Sarah Sharp
Since ohci-hcd supports runtime PM, the .pm field in its pci_driver
structure should be protected by CONFIG_PM rather than
CONFIG_PM_SLEEP.
Without this change, OHCI controllers won't do runtime suspend if
system suspend or hibernation isn't enabled.

usb: patches for v3.12 merge window (part 2)
Here's a set of important fixes for v3.12 merge
window which have been pending in the mailing list
for quite some time.
We have use-after-free fixes, signedness fixes,
more of HAS_DMA dependencies, fixes for NULL pointer
deferences, build fixes and some other fixes to
the musb driver caused by recent patches.
Patches are quite small and contain valuable fixes
which will give us a much better -rc1 release.

MUSB driver, whereby board data was checked before use in all but one
occasion. It is believed that it needs to be checked every time.
