Memory hotplug and hotremove operate with per-block granularity. If the machine has a large amount of memory (more than 64G), the size of a memory block can span multiple sections. By mistake, during hotremove we set only the first section to offline state. The bug was discovered because kernel selftest started to fail: https://lkml.kernel.org/r/20180423011247.GK5563@yexl-desktop After commit, "mm/memory_hotplug: optimize probe routine". But, the bug is older than this commit. In this optimization we also added a check for sections to be in a proper state during hotplug operation.

Jeffrey Hugo authored
load_module() creates W+X mappings via __vmalloc_node_range() (from layout_and_allocate()->move_module()->module_alloc()) by using PAGE_KERNEL_EXEC. These mappings are later cleaned up via "call_rcu_sched(&freeinit->rcu, do_free_init)" from do_init_module(). This is a problem because call_rcu_sched() queues work, which can be run after debug_checkwx() is run, resulting in a race condition. If hit, the race results in a nasty splat about insecure W+X mappings, which results in a poor user experience as these are not the mappings that debug_checkwx() is intended to catch. This issue is observed on multiple arm64 platforms, and has been artificially triggered on an x86 platform. Address the race by flushing the queued work before running the arch-defined mark_rodata_ro() which then calls debug_checkwx().

test_find_first_bit() is intentionally sub-optimal, and may cause soft lockup due to long time of run on some systems. So decrease length of bitmap to traverse to avoid lockup.

Commit 3a4d44b6 ("ntp: Move adjtimex related compat syscalls to native counterparts") removed the memset() in compat_get_timex(). Since then, the compat adjtimex syscall can invoke do_adjtimex() with an uninitialized ->tai. If do_adjtimex() doesn't write to ->tai (e.g. because the arguments are invalid), compat_put_timex() then copies the uninitialized ->tai field to userspace. Fix it by adding the memset() back.

Commit 0847684c (PCI / PM: Simplify device wakeup settings code) went too far and dropped the device_may_wakeup() check from pci_enable_wake() which causes wakeup to be enabled during system suspend, hibernation or shutdown for some PCI devices that are not allowed by user space to wake up the system from sleep (or power off). As a result of this, excessive power is drawn by some of the affected systems while in sleep states or off. Restore the device_may_wakeup() check in pci_enable_wake(), but make sure that the PCI bus type's runtime suspend callback will not call device_may_wakeup() which is about system wakeup from sleep and not about device wakeup from runtime suspend.

Merge tag 'exynos-drm-fixes-for-v4.17-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes Fixup pagefault issue of mixer driver - it makes sure to check shadow register for interlace scan. - it corrects chroma_addr[1], height and vertical position values. And trivial cleanup - it just removes duplicated drm_bridge_attach. * tag 'exynos-drm-fixes-for-v4.17-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: drm/exynos: hdmi: avoid duplicating drm_bridge_attach drm/exynos: mixer: avoid Oops in vp_video_buffer() drm/exynos/mixer: fix synchronization check in interlaced mode

Both ‘uninorth_remove_memory’ and ‘null_cache_flush’ can be made static. So make them. Silence the following gcc warning (W=1): drivers/char/agp/uninorth-agp.c:198:5: warning: no previous prototype for ‘uninorth_remove_memory’ [-Wmissing-prototypes] and drivers/char/agp/uninorth-agp.c:473:6: warning: no previous prototype for ‘null_cache_flush’ [-Wmissing-prototypes] Signed-off-by:

GFP_TRANSHUGE tries very hard to allocate huge pages, which can result in long delays with high memory pressure. I have observed firefox freezing for up to around a minute due to this while restic was taking a full system backup. Since we don't really need huge pages, use GFP_TRANSHUGE_LIGHT | __GFP_NORETRY instead, in order to fail quickly when there are no huge pages available. Set __GFP_KSWAPD_RECLAIM as well, in order for huge pages to be freed up in the background if necessary. With these changes, I'm no longer seeing freezes during a restic backup.

Allocating up to 32 physically contiguous pages can easily fail (and has failed for me), and isn't necessary anyway. Reviewed-by:

USB controller ASM1042 stops working after commit de3ef1eb (PM / core: Drop run_wake flag from struct dev_pm_info). The device in question is not power managed by platform firmware, furthermore, it only supports PME# from D3cold: Capabilities: [78] Power Management version 3 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0-,D1-,D2-,D3hot-,D3cold+) Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME- Before commit de3ef1eb, the device never gets runtime suspended. After that commit, the device gets runtime suspended to D3hot, which can not generate any PME#. usb_hcd_pci_probe() unconditionally calls device_wakeup_enable(), hence device_can_wakeup() in pci_dev_run_wake() always returns true. So pci_dev_run_wake() needs to check PME wakeup capability as its first condition. In addition, change wakeup flag passed to pci_target_state() from false to true, because we want to find the deepest state different from D3cold that the device can still generate PME#. In this case, it's D0 for the device in question. Fixes: de3ef1eb (PM / core: Drop run_wake flag from struct dev_pm_info) Signed-off-by:

If the next_freq field of struct sugov_policy is set to UINT_MAX, it shouldn't be used for updating the CPU frequency (this is a special "invalid" value), but after commit b7eaf1aa (cpufreq: schedutil: Avoid reducing frequency of busy CPUs prematurely) it may be passed as the new frequency to sugov_update_commit() in sugov_update_single(). Fix that by adding an extra check for the special UINT_MAX value of next_freq to sugov_update_single().

After commit 794a56eb (sched/cpufreq: Change the worker kthread to SCHED_DEADLINE) schedutil kthreads are "ignored" for a clock frequency selection point of view, so the potential corner case for RT tasks is not possible at all now. Remove the stale comment mentioning it. Signed-off-by:
