Pull ARM SoC updates from Olof Johansson: "A few SoC (code) changes have queued up this cycle, mostly for minor changes and some refactoring and cleanup of legacy platforms. This branch also contains a few of the fixes that weren't sent in by the end of the release (all fairly minor). - Adding an additional maintainer for the TEE subsystem (Sumit Garg) - Quite a significant modernization of the IXP4xx platforms by Linus Walleij, revisiting with a new PCI host driver/binding, removing legacy mach/* include dependencies and moving platform detection/config to drivers/soc. Also some updates/cleanup of platform data. - Core power domain support for Tegra platforms, and some improvements in build test coverage by adding stubs for compile test targets. - A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP support on i.MX7D, SoC ID setup for i.MX50, removal of platform data and board fixups for iMX6/7. ... and a few smaller changes and fixes for Samsung, OMAP, Allwinner, Rockchip" * tag 'arm-soc-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (53 commits) MAINTAINERS: Add myself as TEE subsystem reviewer ixp4xx: fix spelling mistake in Kconfig "Devce" -> "Device" hw_random: ixp4xx: Add OF support hw_random: ixp4xx: Add DT bindings hw_random: ixp4xx: Turn into a module hw_random: ixp4xx: Use SPDX license tag hw_random: ixp4xx: enable compile-testing pata: ixp4xx: split platform data to its own header soc: ixp4xx: move cpu detection to linux/soc/ixp4xx/cpu.h PCI: ixp4xx: Add a new driver for IXP4xx PCI: ixp4xx: Add device tree bindings for IXP4xx ARM/ixp4xx: Make NEED_MACH_IO_H optional ARM/ixp4xx: Move the virtual IObases MAINTAINERS: ARM/MStar/Sigmastar SoCs: Add a link to the MStar tree ARM: debug: add UART early console support for MSTAR SoCs ARM: dts: ux500: Fix LED probing ARM: imx: add smp support for imx7d ARM: imx6q: drop of_platform_default_populate() from init_machine arm64: dts: rockchip: Update RK3399 PCI host bridge window to 32-bit address memory soc/tegra: fuse: Fix Tegra234-only builds ...

Pull memblock fix from Mike Rapoport: "This is a fix for the rework of ARM's pfn_valid() implementation merged during this merge window. Don't abuse pfn_valid() to check if pfn is in RAM The semantics of pfn_valid() is to check presence of the memory map for a PFN and not whether a PFN is in RAM. The memory map may be present for a hole in the physical memory and if such hole corresponds to an MMIO range, __arm_ioremap_pfn_caller() will produce a WARN() and fail.

Pull percpu fix from Dennis Zhou: "This is just a single change to fix percpu depopulation. The code relied on depopulation code written specifically for the free path and relied on vmalloc to do the tlb flush lazily. As we're modifying the backing pages during the lifetime of a chunk, we need to also flush the tlb accordingly. Guenter Roeck reported this issue in [1] on mips. I believe we just happen to be lucky given the much larger chunk sizes on x86 and consequently less churning of this memory" Link: https://lore.kernel.org/lkml/20210702191140.GA3166599@roeck-us.net/ [1] * 'for-5.14-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu: percpu: flush tlb in pcpu_reclaim_populated()

We have requests like IORING_OP_FILES_UPDATE that don't go through ->iopoll_list but get completed in place under ->uring_lock, and so after dropping the lock io_iopoll_check() should expect that some CQEs might have get completed in a meanwhile. Currently such events won't be accounted in @nr_events, and the loop will continue to poll even if there is enough of CQEs. It shouldn't be a problem as it's not likely to happen and so, but not nice either. Just return earlier in this case, it should be enough. Signed-off-by:

flush_tlb_range is special in that we don't specify the page size used for the translation. Hence when flushing TLB we flush the translation cache for all possible page sizes. The kernel also uses the same interface when moving page tables around. Such a move requires us to flush the page walk cache. Instead of adding another interface to force page walk cache flush, update flush_tlb_range to flush page walk cache if the range flushed is more than the PMD range. A page table move will always involve an invalidate range more than PMD_SIZE. Running microbenchmark with mprotect and parallel memory access didn't show any observable performance impact.

Patch series "Speedup mremap on ppc64", v8. This patchset enables MOVE_PMD/MOVE_PUD support on power. This requires the platform to support updating higher-level page tables without updating page table entries. This also needs to invalidate the Page Walk Cache on architecture supporting the same. This patch (of 3): Architectures like ppc64 support faster mremap only with radix translation. Hence allow a runtime check w.r.t support for fast mremap.

To avoid a race between rmap walk and mremap, mremap does take_rmap_locks(). The lock was taken to ensure that rmap walk don't miss a page table entry due to PTE moves via move_pagetables(). The kernel does further optimization of this lock such that if we are going to find the newly added vma after the old vma, the rmap lock is not taken. This is because rmap walk would find the vmas in the same order and if we don't find the page table attached to older vma we would find it with the new vma which we would iterate later. As explained in commit eb66ae03 ("mremap: properly flush TLB before releasing the page") mremap is special in that it doesn't take ownership of the page. The optimized version for PUD/PMD aligned mremap also doesn't hold the ptl lock. This can result in stale TLB entries as show below. This patch updates the rmap locking requirement in mremap to handle the race condition explained below with optimized mremap:: Optmized PMD move CPU 1 CPU 2 CPU 3 mremap(old_addr, new_addr) page_shrinker/try_to_unmap_one mmap_write_lock_killable() addr = old_addr lock(pte_ptl) lock(pmd_ptl) pmd = *old_pmd pmd_clear(old_pmd) flush_tlb_range(old_addr) *new_pmd = pmd *new_addr = 10; and fills TLB with new addr and old pfn unlock(pmd_ptl) ptep_clear_flush() old pfn is free. Stale TLB entry Optimized PUD move also suffers from a similar race. Both the above race condition can be fixed if we force mremap path to take rmap lock.

Add "auto" to the usage message so that it's a little clearer that you can pass "auto" as the second argument. When passing "auto" the script tries to find the base path automatically instead of requiring it be passed on the commandline. Also use [<variable>] to indicate the variable argument and that it is optional so that we can differentiate from the literal "auto" that should be passed.
