Pull ARM SoC fixes from Olof Johansson: "Seems like we've had more fixes than usual this release cycle, but there's nothing in particular that we're doing differently. Perhaps it's just one of those cycles where more people are finding more regressions (and/or that the latency of when people actually test what's been in the tree for a while is catching up so that we get the bug reports now). The bigger changes here are are for TI and Marvell platforms: * Timing changes for GPMC (generic localbus) on OMAP causing some largeish DTS deltas. * Fixes to window allocation on PCI for mvebu touching drivers/ stuff. Patches have acks from subsystem maintainers where needed. * A fix from Thomas for a botched DT conversion in drivers/edma. There's a handful of other fixes for the above platforms as well as sunxi, at91, i.MX. I also included a MAINTAINER update for Broadcom, and a trivial move of a binding doc. I know you said you'd be offline this week, but I might as well post it for when you return. :)" I'm not quite offline yet.

It's critical for split_huge_page() (and migration) to catch and freeze all PMDs on rmap walk. It gets tricky if there's concurrent fork() or mremap() since usually we copy/move page table entries on dup_mm() or move_page_tables() without rmap lock taken. To get it work we rely on rmap walk order to not miss any entry. We expect to see destination VMA after source one to work correctly. But after switching rmap implementation to interval tree it's not always possible to preserve expected walk order. It works fine for dup_mm() since new VMA has the same vma_start_pgoff() / vma_last_pgoff() and explicitly insert dst VMA after src one with vma_interval_tree_insert_after(). But on move_vma() destination VMA can be merged into adjacent one and as result shifted left in interval tree. Fortunately, we can detect the situation and prevent race with rmap walk by moving page table entries under rmap lock. See commit 38a76013. Problem is that we miss the lock when we move transhuge PMD. Most likely this bug caused the crash[1].

Commit 8910ae89 ("kmemleak: change some global variables to int"), in addition to the atomic -> int conversion, moved the disabling of kmemleak_early_log to the beginning of the kmemleak_init() function, before the full kmemleak tracing is actually enabled. In this small window, kmem_cache_create() is called by kmemleak which triggers additional memory allocation that are not traced. This patch restores the original logic with kmemleak_early_log disabling when kmemleak is fully functional.

Pull x86 fixes from Peter Anvin: "A somewhat unpleasantly large collection of small fixes. The big ones are the __visible tree sweep and a fix for 'earlyprintk=efi,keep'. It was using __init functions with predictably suboptimal results. Another key fix is a build fix which would produce output that simply would not decompress correctly in some configuration, due to the existing Makefiles picking up an unfortunate local label and mistaking it for the global symbol _end. Additional fixes include the handling of 64-bit numbers when setting the vdso data page (a latent bug which became manifest when i386 started exporting a vdso with time functions), a fix to the new MSR manipulation accessors which would cause features to not get properly unblocked, a build fix for 32-bit userland, and a few new platform quirks" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, vdso, time: Cast tv_nsec to u64 for proper shifting in update_vsyscall() x86: Fix typo in MSR_IA32_MISC_ENABLE_LIMIT_CPUID macro x86: Fix typo preventing msr_set/clear_bit from having an effect x86/intel: Add quirk to disable HPET for the Baytrail platform x86/hpet: Make boot_hpet_disable extern x86-64, build: Fix stack protector Makefile breakage with 32-bit userland x86/reboot: Add reboot quirk for Certec BPC600 asmlinkage: Add explicit __visible to drivers/*, lib/*, kernel/* asmlinkage, x86: Add explicit __visible to arch/x86/* asmlinkage: Revert "lto: Make asmlinkage __visible" x86, build: Don't get confused by local symbols x86/efi: earlyprintk=efi,keep fix

With tk->wall_to_monotonic.tv_nsec being a 32-bit value on 32-bit systems, (tk->wall_to_monotonic.tv_nsec << tk->shift) in update_vsyscall() may lose upper bits or, worse, add them since compiler will do this: (u64)(tk->wall_to_monotonic.tv_nsec << tk->shift) instead of ((u64)tk->wall_to_monotonic.tv_nsec << tk->shift) So if, for example, tv_nsec is 0x800000 and shift is 8 we will end up with 0xffffffff80000000 instead of 0x80000000. And then we are stuck in the subsequent 'while' loop. We need an explicit cast.

Commit de7b2973 "tracepoint: Use struct pointer instead of name hash for reg/unreg tracepoints" introduces a use after free by calling release_probes on the old struct tracepoint array before the newly allocated array is published with rcu_assign_pointer. There is a race window where tracepoints (RCU readers) can perform a "use-after-grace-period-after-free", which shows up as a GPF in stress-tests.

The replacement of the 'count' variable by two variables 'incs' and 'decs' to resolve some race conditions during module unloading was done in parallel with some cleanup in the trace subsystem, and was integrated as a merge. Unfortunately, the formula for this replacement was wrong in the tracing code, and the refcount in the traces was not usable as a result. Use 'count = incs - decs' to compute the user count.

This reverts commit c42deffd. commit <mmc: rtsx: add support for pre_req and post_req> did use mutex_unlock() in tasklet, but mutex_unlock() can't be used in tasklet(atomic context). The driver needs to use mutex to avoid concurrency, so we can't use tasklet here, the patch need to be removed. The spinlock host->lock and pcr->lock may deadlock, one way to solve the deadlock is remove host->lock in sd_isr_done_transfer(), but if using workqueue the we can avoid using the spinlock and also avoid the problem.

If you are using a 64-bit kernel with 32-bit userland, then scripts/gcc-x86_64-has-stack-protector.sh invokes 32-bit gcc with -mcmodel=kernel, which produces: <stdin>:1:0: error: code model 'kernel' not supported in the 32 bit mode and trips the "broken compiler" test at arch/x86/Makefile:120. There are several places a fix is possible, but the following seems cleanest. (But it's minimal; it would also be possible to factor out a bunch of stuff from the two branches of the if.)

this is the next pull quested for stashed up radeon fixes for 3.15. As discussed support for Mullins was separated out and will get it's own pull request. Remaining highlights are: 1. Some more patches to better handle PLL limits. 2. Making use of the PFLIP additional to the VBLANK interrupt, otherwise we sometimes miss page flip events. 3. Fix for the UVD command stream parser. 4. Fix for bootup UVD clocks on RV7xx systems. 5. Adding missing error check on dpcd reads. 6. Fixes number of banks calculation on SI. * 'drm-fixes-3.15' of git://people.freedesktop.org/~deathsimple/linux: drm/radeon: lower the ref * post PLL maximum drm/radeon: check that we have a clock before PLL setup drm/radeon: drm/radeon: add missing radeon_semaphore_free to error path drm/radeon: Fix num_banks calculation for SI drm/radeon/dp: check for errors in dpcd reads drm/radeon: avoid high jitter with small frac divs drm/radeon: check buffer relocation offset drm/radeon: use pflip irq on R600+ v2 drm/radeon/uvd: use lower clocks on old UVD to boot v2
