2012-10-04crypto: x86/glue_helper - fix storing of new IV in CBC encryptionJussi Kivilinna
Glue_helper incorrectly XORs new IV over old IV at end of CBC encryption function when it should store. This causes CBC encryption to give incorrect output on multi-page encryption requests.

2012-10-04drm/i915: don't frob the vblank ts in finish_page_flipDaniel Vetter
Now that we correctly generate it, this hack is no longer required (and might actually paper over a serious bug). pageflip timestamps are sanity check in the latest version of the flip-test in intel-gpu-tools. v2: Also remove the gettimeofday(&now) which is no longer used.

2012-10-04drm/i915: call drm_handle_vblank before finish_page_flipDaniel Vetter
... since finish_page_flip needs the vblank timestamp generated in drm_handle_vblank. Somehow all the gmch platforms get it right, but all the pch platform irq handlers get is wrong. Hooray for copy& pasting! Currently this gets papered over by a gross hack in finish_page_flip. A second patch will remove that. Note that without this, the new timestamp sanity checks in flip_test occasionally get tripped up, hence the cc: stable tag.

2012-10-04powerpc/iommu: Fix multiple issues with IOMMU pools codeAnton Blanchard
There are a number of issues in the recent IOMMU pools code: - On a preempt kernel we might switch CPUs in the middle of building a scatter gather list. When this happens the handle hint passed in no longer falls within the local CPU's pool. Check for this and fall back to the pool hint. - We were missing a spin_unlock/spin_lock in one spot where we switch pools. - We need to provide locking around dart_tlb_invalidate_all and dart_tlb_invalidate_one now that the global lock is gone.

In 2fae7cdb60240e2e2d9b378afbf6d9fcce8a3890 ("powerpc: Fix VMX in interrupt check in POWER7 copy loops"), Anton inadvertently introduced a regression for memcpy on POWER7 machines. copyuser and memcpy diverge slightly in their use of cr1 (copyuser doesn't use it, but memcpy does) and you end up clobbering that register with your fix.

Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked."

2012-10-03IB/iser: Add more RX CQs to scale out processing of SCSI responsesAlex Tabachnik
RX/TX CQs will now be selected from a per HCA pool. For the RX flow this has the effect of using different interrupt vectors when using low level drivers (such as mlx4) that map the "vector" param provided by the ULP on CQ creation to a dedicated IRQ/MSI-X vector. This allows the RX flow processing of IO responses to be distributed across multiple CPUs. QPs (--> iSER sessions) are assigned to CQs in round robin order using the CQ with the minimum number of sessions attached to it.

2012-10-03firmware: teach the kernel to load firmware files directly from the filesystemLinus Torvalds
This is a first step in allowing people to by-pass udev for loading device firmware. Current versions of udev will deadlock (causing us to block for the 30 second timeout) under some circumstances if the firmware is loaded as part of the module initialization path, and this is causing problems for media drivers in particular. The current patch hardcodes the firmware path that udev uses by default, and will fall back to the legacy udev mode if the firmware cannot be found there. We'd like to add support for both configuring the paths and the fallback behaviour, but in the meantime this hopefully fixes the immediate problem, while also giving us a way forward.

2012-10-03xtensa: drop CONFIG_EMBEDDED_RAMDISKMax Filippov
Remove Kconfig entries, boot subdirectory, dependencies from other boot-* Makefiles, and sections from ld scripts. Remove stale redboot code that used to pass initrd addresses in a3 and a4 to _start. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Chris Zankel <chris@zankel.net>
2012-10-03xtensa: fix TIOCGSERIAL and TIOCSSERIAL definitionsMax Filippov
Put equivalent constants into TIOCGSERIAL and TIOCSSERIAL definitions: size subfield of these IOCTL codes is not used and no other architecture uses _IO* macros here. The other way could be putting #include <linux/serial.h> into net/bluetooth/rfcomm/tty.c. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Chris Zankel <chris@zankel.net>
