Linus Torvalds 2dc10ad81f arm64 updates for 4.4: ... - "genirq: Introduce generic irq migration for cpu hotunplugged" patch merged from tip/irq/for-arm to allow the arm64-specific part to be upstreamed via the arm64 tree - CPU feature detection reworked to cope with heterogeneous systems where CPUs may not have exactly the same features. The features reported by the kernel via internal data structures or ELF_HWCAP are delayed until all the CPUs are up (and before user space starts) - Support for 16KB pages, with the additional bonus of a 36-bit VA space, though the latter only depending on EXPERT - Implement native {relaxed, acquire, release} atomics for arm64 - New ASID allocation algorithm which avoids IPI on roll-over, together with TLB invalidation optimisations (using local vs global where feasible) - KASan support for arm64 - EFI_STUB clean-up and isolation for the kernel proper (required by KASan) - copy_{to,from,in}_user optimisations (sharing the memcpy template) - perf: moving arm64 to the arm32/64 shared PMU framework - L1_CACHE_BYTES increased to 128 to accommodate Cavium hardware - Support for the contiguous PTE hint on kernel mapping (16 consecutive entries may be able to use a single TLB entry) - Generic CONFIG_HZ now used on arm64 - defconfig updates -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWOkmIAAoJEGvWsS0AyF7x4GgQAINU3NePjFFvWZNCkqobeH9+ jFKwtXamIudhTSdnXNXyYWmtRL9Krg3qI4zDQf68dvDFAZAze2kVuOi1yPpCbpFZ /j/afNyQc7+PoyqRAzmT+EMPZlcuOA84Prrl1r3QWZ58QaFeVk/6ZxrHunTHxN0x mR9PIXfWx73MTo+UnG8FChkmEY6LmV4XpemgTaMR9FqFhdT51OZSxDDAYXOTm4JW a5HdN9OWjjJ2rhLlFEaC7tszG9B5doHdy2tr5ge/YERVJzIPDogHkMe8ZhfAJc+x SQU5tKN6Pg4MOi+dLhxlk0/mKCvHLiEQ5KVREJnt8GxupAR54Bat+DQ+rP9cSnpq dRQTcARIOyy9LGgy+ROAsSo+NiyM5WuJ0/WJUYKmgWTJOfczRYoZv6TMKlwNOUYb tGLCZHhKPM3yBHJlWbQykl3xmSuudxCMmjlZzg7B+MVfTP6uo0CRSPmYl+v67q+J bBw/Z2RYXWYGnvlc6OfbMeImI6prXeE36+5ytyJFga0m+IqcTzRGzjcLxKEvdbiU pr8n9i+hV9iSsT/UwukXZ8ay6zH7PrTLzILWQlieutfXlvha7MYeGxnkbLmdYcfe GCj374io5cdImHcVKmfhnOMlFOLuOHphl9cmsd/O2LmCIqBj9BIeNH2Om8mHVK2F YHczMdpESlJApE7kUc1e =3six -----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: - "genirq: Introduce generic irq migration for cpu hotunplugged" patch merged from tip/irq/for-arm to allow the arm64-specific part to be upstreamed via the arm64 tree - CPU feature detection reworked to cope with heterogeneous systems where CPUs may not have exactly the same features.
