Although there isn't tonnes of code in terms of line count, there are a fair few headline features which I've noted both in the tag and also in the merge commits when I pulled everything together. The part I'm most pleased with is that we had 35 contributors this time around, which feels like a big jump from the usual small group of core arm64 arch developers. Hopefully they all enjoyed it so much that they'll continue to contribute, but we'll see. The pull should be straightforward, but it's probably worth highlighting the following: * We've pulled in a branch from the risc-v folks which moves our CPU topology code out to where it can be shared with others. * There are a few small changes outside of the files we usually touch (e.g. char/random.c) but these have all been reviewed/acked by the relevant maintainers. * There are a couple of very trivial conflicts in linux-next; one is in arch/Kconfig with the Power tree where you can take both hunks, and the other is the removal of our asm/dma-mapping.h file by Christoph where you can just remove the file/ignore our change. * I've renewed the expiry date on my pgp key, so you may need to refetch from the kernel.org keys repository. Cheers, Will --->8 The following changes since commit e21a712a9685488f5ce80495b37b9fdbe96c230d: Linux 5.3-rc3 (2019-08-04 18:40:12 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git tags/arm64-upstream for you to fetch changes up to e376897f424a1c807779a2635f62eb02d7e382f9: arm64: remove __iounmap (2019-09-04 13:12:26 +0100) ---------------------------------------------------------------- arm64 updates for 5.4: - 52-bit virtual addressing in the kernel - New ABI to allow tagged user pointers to be dereferenced by syscalls - Early RNG seeding by the bootloader - Improve robustness of SMP boot - Fix TLB invalidation in light of recent architectural clarifications - Support for i.MX8 DDR PMU - Remove direct LSE instruction patching in favour of static keys - Function error injection using kprobes - Support for the PPTT "thread" flag introduced by ACPI 6.3 - Move PSCI idle code into proper cpuidle driver - Relaxation of implicit I/O memory barriers - Build with RELR relocations when toolchain supports them - Numerous cleanups and non-critical fixes ---------------------------------------------------------------- Andrew Murray (5): jump_label: Don't warn on __exit jump entries arm64: Use correct ll/sc atomic constraints arm64: atomics: avoid out-of-line ll/sc atomics arm64: avoid using hard-coded registers for LSE atomics arm64: atomics: Remove atomic_ll_sc compilation unit Andrey Konovalov (3): arm64: untag user pointers in access_ok and __uaccess_mask_ptr selftests, arm64: add a selftest for passing tagged pointers to kernel selftests, arm64: fix uninitialized symbol in tags_test.c Atish Patra (4): dt-binding: cpu-topology: Move cpu-map to a common binding. cpu-topology: Move cpu topology code to common code. arm: Use common cpu_topology structure and functions.
