2018-02-20arm_pmu: add armpmu_alloc_atomic()Mark Rutland
In ACPI systems, we don't know the makeup of CPUs until we hotplug them on, and thus have to allocate the PMU datastructures at hotplug time. Thus, we must use GFP_ATOMIC allocations. Let's add an armpmu_alloc_atomic() that we can use in this case.

2018-02-20arm_pmu: fold platform helpers into platform codeMark Rutland
The armpmu_{request,free}_irqs() helpers are only used by arm_pmu_platform.c, so let's fold them in and make them static. Signed-off-by: Mark Rutland <mark.rutland@arm.com> Cc: Will Deacon <will.deacon@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
2018-02-20arm_pmu: kill arm_pmu_platdataMark Rutland
Now that we have no platforms passing platform data to the arm_pmu code, we can get rid of the platdata and associated hooks, paving the way for rework of our IRQ handling.

2018-02-20drm/meson: fix vsync buffer updateNeil Armstrong
The plane buffer address/stride/height was incorrectly updated in the plane_atomic_update operation instead of the vsync irq. This patch delays this operation in the vsync irq along with the other plane delayed setup. This issue was masked using legacy framebuffer and X11 modesetting, but is clearly visible using gbm rendering when buffer is submitted late after vblank, like using software decoding and OpenGL rendering in Kodi. With this patch, tearing and other artifacts disappears completely.

One nasty very old crash around polling for buffers that aren't there - though that can only cause effects on drivers that support events but not buffers. * buffer / kfifo handling in the core. - Check there is a buffer and return 0 from poll directly if there isn't. Poll doesn't make sense in this circumstances, but best to close the hole. * ad5933 - Change the marked buffer mode to a software buffer as the meaning of the hardware buffer label has long since changed and this uses a front end software buffer anyway. * ad7192 - Fix the fact the external clock frequency was only set when using the internal clock which was less than helpful. * adis_lib - Initialize the trigger before requesting the interrupt. Some newer parts can power up with interrupt generation enabled so ordering now matters. * aspeed-adc - Fix an errror handling path as labels and general ordering were wrong. * srf08 - Fix a link error due to undefined devm_iio_triggered_buffer_setup. * stm32-adc - Fix error handling unwind squence in stm32h7_adc_enable.
2018-02-20drm: Handle unexpected holes in color-evictionChris Wilson
During eviction, the driver may free more than one hole in the drm_mm due to the side-effects in evicting the scanned nodes. However, drm_mm_scan_color_evict() expects that the scan result is the first available hole (in the mru freed hole_stack list): kernel BUG at drivers/gpu/drm/drm_mm.c:844! invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI Dumping ftrace buffer: (ftrace buffer empty) Modules linked in: i915 snd_hda_codec_analog snd_hda_codec_generic coretemp snd_hda_intel snd_hda_codec snd_hwdep snd_hda_core lpc_ich snd_pcm e1000e mei_me prime_numbers mei CPU: 1 PID: 1490 Comm: gem_userptr_bli Tainted: G U 4.16.0-rc1-g740f57c54ecf-kasan_6+ #1 Hardware name: Dell Inc.

2018-02-20drm/exynos: g2d: use monotonic timestampsArnd Bergmann
The exynos DRM driver uses real-time 'struct timeval' values for exporting its timestamps to user space. This has multiple problems: 1. signed seconds overflow in y2038 2. the 'struct timeval' definition is deprecated in the kernel 3. time may jump or go backwards after a 'settimeofday()' syscall 4. other DRM timestamps are in CLOCK_MONOTONIC domain, so they can't be compared 5. exporting microseconds requires a division by 1000, which may be slow on some architectures. The code existed in two places before, but the IPP portion was removed in 8ded59413ccc ("drm/exynos: ipp: Remove Exynos DRM IPP subsystem"), so we no longer need to worry about it. Ideally timestamps should just use 64-bit nanoseconds instead, but of course we can't change that now. Instead, this tries to address the first four points above by using monotonic 'timespec' values. According to Tobias Jakobi, user space doesn't care about the timestamp at the moment, so we can change the format. Even if there is something looking at them, it will work just fine with monotonic times as long as the application only looks at the relative values between two events.

2018-02-19arm64: __show_regs: Only resolve kernel symbols when running at EL1Will Deacon
__show_regs pretty prints PC and LR by attempting to map them to kernel function names to improve the utility of crash reports. Unfortunately, this mapping is applied even when the pt_regs corresponds to user mode, resulting in a KASLR oracle.

When mlxsw replaces (or deletes) a route it removes the offload indication from the replaced route.

2018-02-19arm64: uaccess: Formalise types for access_ok()Robin Murphy
In converting __range_ok() into a static inline, I inadvertently made it more type-safe, but without considering the ordering of the relevant conversions. This leads to quite a lot of Sparse noise about the fact that we use __chk_user_ptr() after addr has already been converted from a user pointer to an unsigned long. Rather than just adding another cast for the sake of shutting Sparse up, it seems reasonable to rework the types to make logical sense (although the resulting codegen for __range_ok() remains identical). The only callers this affects directly are our compat traps where the inferred "user-pointer-ness" of a register value now warrants explicit casting.

Some APs include a non global operating class in their extended channel switch information element. In such a case, as the operating class is not known, mac80211 would decide to disconnect. However the specification states that the operating class needs to be taken from Annex E, but it does not specify from which table it should be taken, so it is valid for an AP to use a non global operating class. To avoid possibly unneeded disconnection, in such a case ignore the operating class and assume that the current band is used, and if the resulting channel and band configuration is invalid disconnect.

This ensures that mac80211 allocated management frames are properly aligned, which makes copying them more efficient. For instance, mt76 uses iowrite32_copy to copy beacon frames to beacon template memory on the chip. Misaligned 32-bit accesses cause CPU exceptions on MIPS and should be avoided.

2018-02-19arm64: Fix compilation error while accessing MPIDR_HWID_BITMASK from .S filesBhupesh Sharma
Since commit e1a50de37860 (arm64: cputype: Silence Sparse warnings), compilation of arm64 architecture is broken with the following error messages: AR arch/arm64/kernel/built-in.o arch/arm64/kernel/head.S: Assembler messages: arch/arm64/kernel/head.S:677: Error: found 'L', expected: ')' arch/arm64/kernel/head.S:677: Error: found 'L', expected: ')' arch/arm64/kernel/head.S:677: Error: found 'L', expected: ')' arch/arm64/kernel/head.S:677: Error: junk at end of line, first unrecognized character is `L' arch/arm64/kernel/head.S:677: Error: unexpected characters following instruction at operand 2 -- `movz x1,:abs_g1_s:0xff00ffffffUL' arch/arm64/kernel/head.S:677: Error: unexpected characters following instruction at operand 2 -- `movk x1,:abs_g0_nc:0xff00ffffffUL' This patch fixes the same by using the UL() macro correctly for assigning the MPIDR_HWID_BITMASK macro value.

2018-02-19mac80211_hwsim: don't use WQ_MEM_RECLAIMJohannes Berg
We're obviously not part of a memory reclaim path, so don't set the flag. This also causes a warning in check_flush_dependency() since we end up in a code path that flushes a non-reclaim workqueue, and we shouldn't do that if we were really part of reclaim.

2018-02-19cfg80211: fix cfg80211_beacon_dupArnd Bergmann
gcc-8 warns about some obviously incorrect code: net/mac80211/cfg.c: In function 'cfg80211_beacon_dup': net/mac80211/cfg.c:2896:3: error: 'memcpy' source argument is the same as destination [-Werror=restrict] From the context, I conclude that we want to copy from beacon into new_beacon, as we do in the rest of the function.
