2015-01-08perf hists: Fix children sort key behaviorNamhyung Kim
When perf report --children resorts output fields, it tries to put caller above the callee. But this was only meaningful for a same thread and doing this requires callchain enabled. So fix its check before comparing the callchain depth. This also changes the hist accumulation tests: In test 3, xmalloc in bash thread should be above than other perf threads due to alphabetical order of comm string. Also it's under page_fault in bash thread since alphabetical order of dso name. The sys_perf_event_open in perf thread is put on the last line since it's self overhead is 0. In test 4, the sys_perf_event_open is put above other perf entries that have same children overhead since its callchain depth is smaller.

2015-01-08x86/xen: avoid freeing static 'name' when kasprintf() failsVitaly Kuznetsov
In case kasprintf() fails in xen_setup_timer() we assign name to the static string "<timer kasprintf failed>". We, however, don't check that fact before issuing kfree() in xen_teardown_timer(), kernel is supposed to crash with 'kernel BUG at mm/slub.c:3341!' Solve the issue by making name a fixed length string inside struct xen_clock_event_device. 16 bytes should be enough.

2015-01-08arm64/efi: add missing call to early_ioremap_reset()Ard Biesheuvel
The early ioremap support introduced by patch bf4b558eba92 ("arm64: add early_ioremap support") failed to add a call to early_ioremap_reset() at an appropriate time. Without this call, invocations of early_ioremap etc. that are done too late will go unnoticed and may cause corruption. This is exactly what happened when the first user of this feature was added in patch f84d02755f5a ("arm64: add EFI runtime services"). The early mapping of the EFI memory map is unmapped during an early initcall, at which time the early ioremap support is long gone. Fix by adding the missing call to early_ioremap_reset() to setup_arch(), and move the offending early_memunmap() to right after the point where the early mapping of the EFI memory map is last used.

The sh73a0 INTC can't mask interrupts properly most likely due to a hardware bug. Set the .control_parent flag to delegate masking to the parent interrupt controller, like was already done for irqpin1. Without this, accessing the three-axis digital accelerometer ADXL345 on kzm9g through /dev/input/event1 causes an interrupt storm, which requires a power-cycle to recover from.

Now local variables kernel_x_start and kernel_x_end defined using 'unsigned long' type which is wrong because they represent physical memory range and will be calculated wrongly if LPAE is enabled. As result, all following code in map_lowmem() will not work correctly. For example, Keystone 2 boot is broken because kernel_x_start == 0x0000 0000 kernel_x_end == 0x0080 0000 instead of kernel_x_start == 0x0000 0008 0000 0000 kernel_x_end == 0x0000 0008 0080 0000 and as result whole low memory will be mapped with MT_MEMORY_RW permissions by code (start > kernel_x_end): } else if (start >= kernel_x_end) { map.pfn = __phys_to_pfn(start); map.virtual = __phys_to_virt(start); map.length = end - start; map.type = MT_MEMORY_RW; create_mapping(&map); } Hence, fix it by using phys_addr_t type for variables kernel_x_start and kernel_x_end.

2015-01-07ARM: 8249/1: mm: dump: don't skip regionsMark Rutland
Currently the arm page table dumping code starts dumping page tables from USER_PGTABLES_CEILING. This is unnecessary for skipping any entries related to userspace as the swapper_pg_dir does not contain such entries, and results in a couple of unfortuante side effects. Firstly, any kernel mappings which might exist below USER_PGTABLES_CEILING will not be accounted in the dump output. This masks any entries erroneously created below this address. Secondly, if the final page table entry walked is part of a valid mapping the page table dumping code will not log the region this entry is part of, as the final note_page call in walk_pgd will trigger an early return when 0 < USER_PGTABLES_CEILING. Luckily this isn't seen on contemporary systems as they typically don't have enough RAM to extend the linear mapping right to the end of the address space. Due to the way addr is constructed in the walk_* functions, it can never be less than USER_PGTABLES_CEILING when walking the page tables, so it is not necessary to avoid dereferencing invalid table addresses. The existing checks for st->current_prot and st->marker[1].start_address are sufficient to ensure we will not print and/or dereference garbage when trying to log information. This patch removes both problematic uses of USER_PGTABLES_CEILING from the arm page table dumping code, preventing both of these issues. We will now report any low mappings, and the final note_page call will not return early, ensuring all regions are logged.

2015-01-07imx-drm: core: handling of DI clock flags to ipu_crtc_mode_set()Russell King
We do not need to track the state of the IPU DI's clock flags by having each display bridge calling back into imx-drm-core, and then back out into ipuv3-crtc.c. ipuv3-crtc can instead just scan the list of encoders to retrieve their type, and build up a picture of which types of encoders are attached. We can then use this information to configure the IPU DI clocking mode without any uncertainty - if we have multiple bridges connected to the same DI, if one of them requires a synchronous DI clock, that's what we must use.

2015-01-07rpc: fix xdr_truncate_encode to handle buffer ending on page boundaryJ. Bruce Fields
A struct xdr_stream at a page boundary might point to the end of one page or the beginning of the next, but xdr_truncate_encode isn't prepared to handle the former. This can cause corruption of NFSv4 READDIR replies in the case that a readdir entry that would have exceeded the client's dircount/maxcount limit would have ended exactly on a 4k page boundary. You're more likely to hit this case on large directories. Other xdr_truncate_encode callers are probably also affected.

2015-01-07drm/i915: Push vblank enable/disable past encoder->enable/disableDaniel Vetter
It is platform/output depenedent when exactly the pipe will start running. Sometimes we just need the (cpu) pipe enabled, in other cases the pch transcoder is enough and in yet other cases the (DP) port is sending the frame start signal. In a perfect world we'd put the drm_crtc_vblank_on call exactly where the pipe starts running, but due to cloning and similar things this will get messy. And the current approach of picking the most conservative place for all combinations also doesn't work since that results in legit vblank waits (in encoder->enable hooks, e.g. the 2 vblank waits for sdvo) failing. Completely going back to the old world before commit 51e31d49c89055299e34b8f44d13f70e19aaaad1 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Sep 15 12:36:02 2014 +0200 drm/i915: Use generic vblank wait isn't great either since screaming when the vblank wait work because the pipe is off is kinda nice. Pick a compromise and move the drm_crtc_vblank_on right before the encoder->enable call. This is a lie on some outputs/platforms, but after the ->enable callback the pipe is guaranteed to run everywhere. So not that bad really. Suggested by Ville. v2: Same treatment for drm_crtc_vblank_off and encoder->disable: I've missed the ibx pipe B select w/a, which also has a vblank wait in the disable function (while the pipe is obviously still running).

2015-01-07assoc_array: Include rcupdate.h for call_rcu() definitionPranith Kumar
Include rcupdate.h header to provide call_rcu() definition. This was implicitly being provided by slab.h file which include srcu.h somewhere in its include hierarchy which in-turn included rcupdate.h. Lately, tinification effort added support to remove srcu entirely because of which we are encountering build errors like lib/assoc_array.c: In function 'assoc_array_apply_edit': lib/assoc_array.c:1426:2: error: implicit declaration of function 'call_rcu' [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors Fix these by including rcupdate.h explicitly.

Although the 't->length' is a big-endian value, it's used without any conversion. This means that the driver always uses 'length' parameter.

2015-01-07ARM: dts: berlin: correct BG2Q's SM GPIO location.Jisheng Zhang
The gpio4 and gpio5 are in 0xf7fc0000 apb which is located in the SM domain. This patch moves gpio4 and gpio5 to the correct location. This patch also renames them as the following to match the names we internally used in marvell: gpio4 -> sm_gpio1 gpio5 -> sm_gpio0 porte -> portf portf -> porte This also matches what we did for BG2 and BG2CD's SM GPIO.

2015-01-07ARM: dts: berlin: add broken-cd and set bus width for eMMC in Marvell DMP DTJisheng Zhang
There's no card detection for the eMMC, so this patch adds the missing broken-cd property. This patch also sets bus width as 8 to add MMC_CAP_8_BIT_DATA in the Host capabilities.

2015-01-07cfg80211: fix deadlock during reg chan checkArik Nemtsov
If a P2P GO is active, the cfg80211_reg_can_beacon function will take the wdev lock, in its call to cfg80211_go_permissive_chan. But the wdev lock is already taken by the parent channel-checking function, causing a deadlock. Split the checking code into two parts. The first part will check if the wdev is active and saves the channel under the wdev lock. The second part will check actual channel validity according to type.
