git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull kmap updates from Thomas Gleixner: "The new preemtible kmap_local() implementation: - Consolidate all kmap_atomic() internals into a generic implementation which builds the base for the kmap_local() API and make the kmap_atomic() interface wrappers which handle the disabling/enabling of preemption and pagefaults. - Switch the storage from per-CPU to per task and provide scheduler support for clearing mapping when scheduling out and restoring them when scheduling back in. - Merge the migrate_disable/enable() code, which is also part of the scheduler pull request. This was required to make the kmap_local() interface available which does not disable preemption when a mapping is established. It has to disable migration instead to guarantee that the virtual address of the mapped slot is the same across preemption. - Provide better debug facilities: guard pages and enforced utilization of the mapping mechanics on 64bit systems when the architecture allows it. - Provide the new kmap_local() API which can now be used to cleanup the kmap_atomic() usage sites all over the place. Most of the usage sites do not require the implicit disabling of preemption and pagefaults so the penalty on 64bit and 32bit non-highmem systems is removed and quite some of the code can be simplified. A wholesale conversion is not possible because some usage depends on the implicit side effects and some need to be cleaned up because they work around these side effects. The migrate disable side effect is only effective on highmem systems and when enforced debugging is enabled. On 64bit and 32bit non-highmem systems the overhead is completely avoided" * tag 'core-mm-2020-12-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits) ARM: highmem: Fix cache_is_vivt() reference x86/crashdump/32: Simplify copy_oldmem_page() io-mapping: Provide iomap_local variant mm/highmem: Provide kmap_local* sched: highmem: Store local kmaps in task struct x86: Support kmap_local() forced debugging mm/highmem: Provide CONFIG_DEBUG_KMAP_LOCAL_FORCE_MAP mm/highmem: Provide and use CONFIG_DEBUG_KMAP_LOCAL microblaze/mm/highmem: Add dropped #ifdef back xtensa/mm/highmem: Make generic kmap_atomic() work correctly mm/highmem: Take kmap_high_get() properly into account highmem: High implementation details and document API Documentation/io-mapping: Remove outdated blurb io-mapping: Cleanup atomic iomap mm/highmem: Remove the old kmap_atomic cruft highmem: Get rid of kmap_types.h xtensa/mm/highmem: Switch to generic kmap atomic sparc/mm/highmem: Switch to generic kmap atomic powerpc/mm/highmem: Switch to generic kmap atomic nds32/mm/highmem: Switch to generic kmap atomic ...

The lifetime counters are used identically for all namespaces types. Namespaces may of course have additional unrelated counters and these are not altered. This work allows us to unify the type of the counters and reduces maintenance cost by moving the counter in one place and indicating that basic lifetime management is identical for all namespaces. - Peilin's fix adding three byte padding to Dmitry's PTRACE_GET_SYSCALL_INFO uapi struct to prevent an info leak. - Two smal patches to convert from the /* fall through */ comment annotation to the fallthrough keyword annotation which I had taken into my branch and into -next before df561f6688fe ("treewide: Use fallthrough pseudo-keyword") made it upstream which fixed this tree-wide.

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull time namespace updates from Christian Brauner: "When time namespaces were introduced we missed to virtualize the 'btime' field in /proc/stat. This confuses tasks which are in another time namespace with a virtualized boottime which is common in some container workloads. This contains Michael's series to fix 'btime' which Thomas asked me to take through my tree. To fix 'btime' virtualization we simply subtract the offset of the time namespace's boottime from btime before printing the stats. Note that since start_boottime of processes are seconds since boottime and the boottime stamp is now shifted according to the time namespace's offset, the offset of the time namespace also needs to be applied before the process stats are given to userspace. This avoids that processes shown by tools such as 'ps' appear as time travelers in the corresponding time namespace. Selftests are included to verify that btime virtualization in /proc/stat works as expected" * tag 'time-namespace-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: namespace: make timens_on_fork() return nothing selftests/timens: added selftest for /proc/stat btime fs/proc: apply the time namespace offset to /proc/stat btime timens: additional helper functions for boottime offset handling

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: - Expose tag address bits in siginfo. The original arm64 ABI did not expose any of the bits 63:56 of a tagged address in siginfo. In the presence of user ASAN or MTE, this information may be useful. The implementation is generic to other architectures supporting tags (like SPARC ADI, subject to wiring up the arch code). The user will have to opt in via sigaction(SA_EXPOSE_TAGBITS) so that the extra bits, if available, become visible in si_addr. - Default to 32-bit wide ZONE_DMA. Previously, ZONE_DMA was set to the lowest 1GB to cope with the Raspberry Pi 4 limitations, to the detriment of other platforms. With these changes, the kernel scans the Device Tree dma-ranges and the ACPI IORT information before deciding on a smaller ZONE_DMA. - Strengthen READ_ONCE() to acquire when CONFIG_LTO=y. When building with LTO, there is an increased risk of the compiler converting an address dependency headed by a READ_ONCE() invocation into a control dependency and consequently allowing for harmful reordering by the CPU. - Add CPPC FFH support using arm64 AMU counters. - set_fs() removal on arm64. This renders the User Access Override (UAO) ARMv8 feature unnecessary. - Perf updates: PMU driver for the ARM DMC-620 memory controller, sysfs identifier file for SMMUv3, stop event counters support for i.MX8MP, enable the perf events-based hard lockup detector. - Reorganise the kernel VA space slightly so that 52-bit VA configurations can use more virtual address space. - Improve the robustness of the arm64 memory offline event notifier. - Pad the Image header to 64K following the EFI header definition updated recently to increase the section alignment to 64K. - Support CONFIG_CMDLINE_EXTEND on arm64. - Do not use tagged PC in the kernel (TCR_EL1.TBID1==1), freeing up 8 bits for PtrAuth. - Switch to vmapped shadow call stacks. - Miscellaneous clean-ups. * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (78 commits) perf/imx_ddr: Add system PMU identifier for userspace bindings: perf: imx-ddr: add compatible string arm64: Fix build failure when HARDLOCKUP_DETECTOR_PERF is enabled arm64: mte: fix prctl(PR_GET_TAGGED_ADDR_CTRL) if TCF0=NONE arm64: mark __system_matches_cap as __maybe_unused arm64: uaccess: remove vestigal UAO support arm64: uaccess: remove redundant PAN toggling arm64: uaccess: remove addr_limit_user_check() arm64: uaccess: remove set_fs() arm64: uaccess cleanup macro naming arm64: uaccess: split user/kernel routines arm64: uaccess: refactor __{get,put}_user arm64: uaccess: simplify __copy_user_flushcache() arm64: uaccess: rename privileged uaccess routines arm64: sdei: explicitly simulate PAN/UAO entry arm64: sdei: move uaccess logic to arch/arm64/ arm64: head.S: always initialize PSTATE arm64: head.S: cleanup SCTLR_ELx initialization arm64: head.S: rename el2_setup -> init_kernel_el arm64: add C wrappers for SET_PSTATE_*() ...

2020-12-14Merge branch 'radeon-fixes' (Radeon and amdgpu fixes)Linus Torvalds2-60/+47
Merge radeon and amdgpu fixes for boot problems. The drm merge ended up causing my AMD workstation to not boot. When reporting this, Alex Deucher correctly blamed commit 28a68f828266 ("drm/radeon/ttm: use multihop") and pointed to these two fixes that were already in the drm-misc tree: 95e3d610d35c ("drm/radeon: fix check order in radeon_bo_move") aefec40938e4 ("drm/amdgpu: fix check order in amdgpu_bo_move") Since I hate doing merges with a known-bad base, I've cherry-picked these fixes into a branch of their own, just to be able to continue my merge window. The original commits will eventually come in as duplicates through the normal channels, but in the meantime we have a tree that isn't broken with basically every AMD GPU out there.

Those reverts exposed a dm-raid.c compiler warning that wasn't ever knowingly introduced. That min_not_zero() type mismatch warning was thought to be safely fixed simply by changing 'struct mddev' to use 'unsigned int' rather than int for chunk_sectors members in that struct. I proposed either using a cast local to dm-raid.c but thought changing the type to 'unsigned int' more correct. While that may be, not enough testing was paired with code review associated with making that change. As such we were left exposed and the result was a report that with v5.10 btrfs on MD RAID6 failed to mount: https://lkml.org/lkml/2020/12/14/7 Given that report, it is justified to simply revert these offending commits. stable@ has already taken steps to revert these for 5.10.1 - this just makes sure mainline does so too" * tag 'for-5.11/revert-problem-v5.10-raid-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: Revert "dm raid: fix discard limits for raid1 and raid10" Revert "md: change mddev 'chunk_sectors' from int to unsigned"

This reverts commit e0910c8e4f87bb9f767e61a778b0d9271c4dc512. Reverting 6ffeb1c3f822 ("md: change mddev 'chunk_sectors' from int to unsigned") exposes dm-raid.c compiler warnings detailed that commit's header. Clearly this more conservative fix, of simply reverting e0910c8e4f8, would've been more prudent given how late we were in the v5.10 release. Lessons have been learned.

Small corrections for assumptions about visibility which have turned out not to be true. - Make the PAT bits for memory encryption correct vs 4K and 2M/1G page table entries as they are at a different location. - Fix a concurrency issue in the the local bandwidth readout of resource control leading to incorrect values - Fix the ordering of allocating a vector for an interrupt. The order missed to respect the provided cpumask when the first attempt of allocating node local in the mask fails. It then tries the node instead of trying the full provided mask first. This leads to erroneous error messages and breaking the (user) supplied affinity request. Reorder it. - Make the INT3 padding detection in optprobe work correctly" * tag 'x86-urgent-2020-12-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/kprobes: Fix optprobe to detect INT3 padding correctly x86/apic/vector: Fix ordering in vector assignment x86/resctrl: Fix incorrect local bandwidth when mba_sc is enabled x86/mm/mem_encrypt: Fix definition of PMD_FLAGS_DEC_WP membarrier: Execute SYNC_CORE on the calling thread membarrier: Explicitly sync remote cores when SYNC_CORE is requested membarrier: Add an actual barrier before rseq_preempt() x86/membarrier: Get rid of a dubious optimization

Pull block fixes from Jens Axboe: "This should be it for 5.10. Mike and Song looked into the warning case, and thankfully it appears the fix was pretty trivial - we can just change the md device chunk type to unsigned int to get rid of it. They cannot currently be < 0, and nobody is checking for that either. We're reverting the discard changes as the corruption reports came in very late, and there's just no time to attempt to deal with it at this point.
