2013-06-06arch, mm: Remove tlb_fast_mode()Peter Zijlstra
Since the introduction of preemptible mmu_gather TLB fast mode has been broken. TLB fast mode relies on there being absolutely no concurrency; it frees pages first and invalidates TLBs later. However now we can get concurrency and stuff goes *bang*. This patch removes all tlb_fast_mode() code; it was found the better option vs trying to patch the hole by entangling tlb invalidation with the scheduler.

2013-06-05ARM: 7747/1: pcpu: ensure __my_cpu_offset cannot be re-ordered across barrier()Will Deacon
__my_cpu_offset is non-volatile, since we want its value to be cached when we access several per-cpu variables in a row with preemption disabled. This means that we rely on preempt_{en,dis}able to hazard with the operation via the barrier() macro, so that we can't end up migrating CPUs without reloading the per-cpu offset. Unfortunately, GCC doesn't treat a "memory" clobber on a non-volatile asm block as a side-effect, and will happily re-order it before other memory clobbers (including those in prempt_disable()) and cache the value. This has been observed to break the cmpxchg logic in the slub allocator, leading to livelock in kmem_cache_alloc in mainline kernels. This patch adds a dummy memory input operand to __my_cpu_offset, forcing it to be ordered with respect to the barrier() macro.

2013-06-05ARM: 7743/1: compressed/head.S: work around new binutils warningArnd Bergmann
In August 2012, Matthew Gretton-Dann checked a change into binutils labelled "Error on obsolete & warn on deprecated registers", apparently as part of ARMv8 support. Apparently, this was supposed to emit the message "Warning: This coprocessor register access is deprecated in ARMv8" when using certain mcr/mrc instructions and building for ARMv8. Unfortunately, the message that is actually emitted appears to be '(null)', which is less helpful in comparison. Even more unfortunately, this is biting us on every single kernel build with a new gas, because arch/arm/boot/compressed/head.S and some other files in that directory are built with -march=all since kernel commit 80cec14a8 "[ARM] Add -march=all to assembly file build in arch/arm/boot/compressed" back in v2.6.28. This patch reverts Russell's nice solution and instead marks the head.S file to be built for armv7-a, which fortunately lets us build all instructions in that file without warnings even on the broken binutils. Without this patch, building anything results in: arch/arm/boot/compressed/head.S: Assembler messages: arch/arm/boot/compressed/head.S:565: Warning: (null) arch/arm/boot/compressed/head.S:676: Warning: (null) arch/arm/boot/compressed/head.S:698: Warning: (null) arch/arm/boot/compressed/head.S:722: Warning: (null) arch/arm/boot/compressed/head.S:726: Warning: (null) arch/arm/boot/compressed/head.S:957: Warning: (null) arch/arm/boot/compressed/head.S:996: Warning: (null) arch/arm/boot/compressed/head.S:997: Warning: (null) arch/arm/boot/compressed/head.S:1027: Warning: (null) arch/arm/boot/compressed/head.S:1035: Warning: (null) arch/arm/boot/compressed/head.S:1046: Warning: (null) arch/arm/boot/compressed/head.S:1060: Warning: (null) arch/arm/boot/compressed/head.S:1092: Warning: (null) arch/arm/boot/compressed/head.S:1094: Warning: (null) arch/arm/boot/compressed/head.S:1095: Warning: (null) arch/arm/boot/compressed/head.S:1102: Warning: (null) arch/arm/boot/compressed/head.S:1134: Warning: (null) Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: stable@vger.kernel.org Cc: Matthew Gretton-Dann <matthew.gretton-dann@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2013-06-05x86/PCI: Map PCI setup data with ioremap() so it can be in highmemMatt Fleming
f9a37be0f0 ("x86: Use PCI setup data") added support for using PCI ROM images from setup_data. This used phys_to_virt(), which is not valid for highmem addresses, and can cause a crash when booting a 32-bit kernel via the EFI boot stub. pcibios_add_device() assumes that the physical addresses stored in setup_data are accessible via the direct kernel mapping, and that calling phys_to_virt() is valid. This isn't guaranteed to be true on x86 where the direct mapping range is much smaller than on x86-64. Calling phys_to_virt() on a highmem address results in the following: BUG: unable to handle kernel paging request at 39a3c198 IP: [<c262be0f>] pcibios_add_device+0x2f/0x90 ...

We must zero out the real key C/R to avoid guest over-indication for change (and reference). Touching the real key is ok also for the host: The change bit is tracked via write protection and the reference bit is also ok because set_pte_at was called and the page will be touched anyway soon.

2013-06-05ACPI / scan: do not match drivers against objects having scan handlersAaron Lu
With the introduction of ACPI scan handlers, an ACPI device object with an ACPI scan handler attached to it must not be bound to an ACPI driver any more. Therefore it doesn't make sense to match those ACPI device objects against a newly registered ACPI driver in acpi_bus_match(), so make that function return 0 if the device object passed to it has an ACPI scan handler attached. This also addresses a regression related to a broken ACPI table in the BIOS, where it has defined a _ROM method under the PCI root bridge object. This causes the video module to treat that object as a display controller device (since only display devices are supposed to have a _ROM method defined according to the ACPI spec). As a result, the ACPI video driver binds to the PCI root bridge object and overwrites the previously assigned driver_data field of it, causing subsequent calls to acpi_get_pci_dev() to fail.

2013-06-05acpi-cpufreq: set current frequency based on target P-StateRoss Lagerwall
Commit 4b31e774 (Always set P-state on initialization) fixed bug #4634 and caused the driver to always set the target P-State at least once since the initial P-State may not be the desired one. Commit 5a1c0228 (cpufreq: Avoid calling cpufreq driver's target() routine if target_freq == policy->cur) caused a regression in this behavior. This fixes the regression by setting policy->cur based on the CPU's target frequency rather than the CPU's current reported frequency (which may be different). This means that the P-State will be set initially if the CPU's target frequency is different from the governor's target frequency. This fixes an issue where setting the default governor to performance wouldn't correctly enable turbo mode on all cores.

2013-06-05drm/i915: consolidate and tighten encoder cloning checksDaniel Vetter
Only lvds/tv did actually check for cloning or not, but many more places should. Notices because my ivb tried to enable both cpu edp and vga on the first crtc - the resulting confusion between has_pch_encoder, has_dp_encoder but not actually being a pch dp encoder resulting in hilarity (hitting a BUG). We _really_ need an igt to random-walk our modeset space more exhaustively. The bug seems to have been exposed due to a race in the hw load detection support for VGA: Right after a hotplug VGA was still detected as connected, but obviously reading the EDID wasn't possible any more. Hence why restarting X a bit later fixed things. Due to the 1024x756 fallback resolution suddenly more outputs had the same resolution. On top of that SNA was confused with the possible_clones mask, trying to clone outputs which cannot be cloned. That bug is now fixed with commit fc1e0702b25e647cb423851fb7228989fec28bd6 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed May 29 11:25:28 2013 +0100 sna: fixup up possible_clones kms->X impedance mismatch v2: Kill intel_encoder_check_is_cloned, spotted by Paulo. v3: Drop the now unused pipe param. v4: Kill the stray printk Chris spotted. v5: Elaborate on how the bug in userspace happened and why it was racy to reproduce.

Code refactoring in commit 8e9e3d2deacc460fbb8a4691140318f6e85e6891 (drm/nv84/disp: move hdmi control into core) disabled HDMI audio on my nv84 by removing too much old code without adding it in the new one. This patch adds the missing code within the new code layout resulting in HDMI audio working again. It should work on any HDMI head, but due to lacking ahrdware I could only test the (1st) one. It also might be possible that similar code is needed for nva3, which I can't test.

2013-06-04net: fix sk_buff head without data areaPablo Neira
Eric Dumazet spotted that we have to check skb->head instead of skb->data as skb->head points to the beginning of the data area of the skbuff. Similarly, we have to initialize the skb->head pointer, not skb->data in __alloc_skb_head. After this fix, netlink crashes in the release path of the sk_buff, so let's fix that as well. This bug was introduced in (0ebd0ac net: add function to allocate sk_buff head without data area).
