2017-06-26drm/i915: Clear execbuf's vma backpointer upon releaseChris Wilson1-0/+1
commit 2889caa92321 ("drm/i915: Eliminate lots of iterations over the execobjects array") jiggled around the error handling and replace a test that we cleaned up properly after ourselves with an assertion. That assertion failed because in the release function (moments after the assertion) we were indeed forgetting to mark the vma as cleared. The consequence was when testing an invalid relocation address, we would try to release the vma twice (following the couple of attempts to verify the address) and on the second release notice that the first release was incomplete.

2017-06-24x86/mshyperv: Remove excess #includes from mshyperv.hThomas Gleixner1-2/+1
A recent commit included linux/slab.h in linux/irq.h. This breaks the build of vdso32 on a 64-bit kernel. The reason is that linux/irq.h gets included into the vdso code via linux/interrupt.h which is included from asm/mshyperv.h. That makes the 32-bit vdso compile fail, because slab.h includes the pgtable headers for 64-bit on a 64-bit build. Neither linux/clocksource.h nor linux/interrupt.h are needed in the mshyperv.h header file itself - it has a dependency on <linux/atomic.h>. Remove the includes and unbreak the build.

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: "Some more powerpc fixes for 4.12. Most of these actually came in last week but got held up for some more testing. - three fixes for kprobes/ftrace/livepatch interactions. - properly handle data breakpoints when using the Radix MMU. - fix for perf sampling of registers during call_usermodehelper(). - properly initialise the thread_info on our emergency stacks - add an explicit flush when doing TLB invalidations for a process using NPU2. Thanks to: Alistair Popple, Naveen N. Rao, Nicholas Piggin, Ravi Bangoria, Masami Hiramatsu" * tag 'powerpc-4.12-7' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/64: Initialise thread_info for emergency stacks powerpc/powernv/npu-dma: Add explicit flush when sending an ATSD powerpc/perf: Fix oops when kthread execs user process powerpc/64s: Handle data breakpoints in Radix mode powerpc/kprobes: Skip livepatch_handler() for jprobes powerpc/ftrace: Pass the correct stack pointer for DYNAMIC_FTRACE_WITH_REGS powerpc/kprobes: Pause function_graph tracing during jprobes handling

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI fix from Rafael Wysocki: "This fixes the ACPI-based enumeration of some I2C and SPI devices broken in 4.11. Specifics: - I2C and SPI devices are expected to be enumerated by the I2C and SPI subsystems, respectively, but due to a change made during the 4.11 cycle, in some cases the ACPI core marks them as already enumerated which causes the I2C and SPI subsystems to overlook them, so fix that (Jarkko Nikula)" * tag 'acpi-4.12-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / scan: Fix enumeration for special SPI and I2C devices
