- On ARMv8 CPUs without hardware updates of the access flag, avoid failing cow_user_page() on PFN mappings if the pte is old. The patches introduce an arch_faults_on_old_pte() macro, defined as false on x86. When true, cow_user_page() makes the pte young before attempting __copy_from_user_inatomic(). - Covert the synchronous exception handling paths in arch/arm64/kernel/entry.S to C. - FTRACE_WITH_REGS support for arm64. - ZONE_DMA re-introduced on arm64 to support Raspberry Pi 4 - Several kselftest cases specific to arm64, together with a MAINTAINERS update for these files (moved to the ARM64 PORT entry). - Workaround for a Neoverse-N1 erratum where the CPU may fetch stale instructions under certain conditions. - Workaround for Cortex-A57 and A72 errata where the CPU may speculatively execute an AT instruction and associate a VMID with the wrong guest page tables (corrupting the TLB). - Perf updates for arm64: additional PMU topologies on HiSilicon platforms, support for CCN-512 interconnect, AXI ID filtering in the IMX8 DDR PMU, support for the CCPI2 uncore PMU in ThunderX2. - GICv3 optimisation to avoid a heavy barrier when accessing the ICC_PMR_EL1 register. - ELF HWCAP documentation updates and clean-up. - SMC calling convention conduit code clean-up. - KASLR diagnostics printed during boot - NVIDIA Carmel CPU added to the KPTI whitelist - Some arm64 mm clean-ups: use generic free_initrd_mem(), remove stale macro, simplify calculation in __create_pgd_mapping(), typos. - Kconfig clean-ups: CMDLINE_FORCE to depend on CMDLINE, choice for endinanness to help with allmodconfig. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAl3YJswACgkQa9axLQDI XvFwYg//aTGhNLew3ADgW2TYal7LyqetRROixPBrzqHLu2A8No1+QxHMaKxpZVyf pt25tABuLtPHql3qBzE0ltmfbLVsPj/3hULo404EJb9HLRfUnVGn7gcPkc+p4YAr IYkYPXJbk6OlJ84vI+4vXmDEF12bWCqamC9qZ+h99qTpMjFXFO17DSJ7xQ8Xic3A HHgCh4uA7gpTVOhLxaS6KIw+AZNYwvQxLXch2+wj6agbGX79uw9BeMhqVXdkPq8B RTDJpOdS970WOT4cHWOkmXwsqqGRqgsgyu+bRUJ0U72+0y6MX0qSHIUnVYGmNc5q Dtox4rryYLvkv/hbpkvjgVhv98q3J1mXt/CalChWB5dG4YwhJKN2jMiYuoAvB3WS 6dR7Dfupgai9gq1uoKgBayS2O6iFLSa4g58vt3EqUBqmM7W7viGFPdLbuVio4ycn CNF2xZ8MZR6Wrh1JfggO7Hc11EJdSqESYfHO6V/pYB4pdpnqJLDoriYHXU7RsZrc HvnrIvQWKMwNbqBvpNbWvK5mpBMMX2pEienA3wOqKNH7MbepVsG+npOZTVTtl9tN FL0ePb/mKJu/2+gW8ntiqYn7EzjKprRmknOiT2FjWWo0PxgJ8lumefuhGZZbaOWt /aTAeD7qKd/UXLKGHF/9v3q4GEYUdCFOXP94szWVPyLv+D9h8L8= =TPL9 -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: "Apart from the arm64-specific bits (core arch and perf, new arm64 selftests), it touches the generic cow_user_page() (reviewed by Kirill) together with a macro for x86 to preserve the existing behaviour on this architecture.
