Subject: [GIT PULL] arm64 updates for 4.2
Hi Linus,
Please pull the arm64 updates below. Thanks.
The following changes since commit e26081808edadfd257c6c9d81014e3b25e9a6118:
Linux 4.1-rc4 (2015-05-18 10:13:47 -0700)
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux tags/arm64-upstream

arm64: use private ratelimit state along with show_unhandled_signals (2015-06-19 16:26:15 +0100)
----------------------------------------------------------------
arm64 updates for 4.2, mostly refactoring/clean-up:
- CPU ops and PSCI (Power State Coordination Interface) refactoring
following the merging of the arm64 ACPI support, together with
handling of Trusted (secure) OS instances
- Using fixmap for permanent FDT mapping, removing the initial dtb
placement requirements (within 512MB from the start of the kernel
image). This required moving the FDT self reservation out of the
memreserve processing
- Idmap (1:1 mapping used for MMU on/off) handling clean-up
- Removing flush_cache_all() - not safe on ARM unless the MMU is off.
Last stages of CPU power down/up are handled by firmware already
- "Alternatives" (run-time code patching) refactoring and support for
immediate branch patching, GICv3 CPU interface access
- User faults handling clean-up
And some fixes:
- Fix for VDSO building with broken ELF toolchains
- Fixing another case of init_mm.pgd usage for user mappings (during
ASID roll-over broadcasting)
- Fix for FPSIMD reloading after CPU hotplug
- Fix for missing syscall trace exit
- Workaround for .inst asm bug
- Compat fix for switching the user tls tpidr_el0 register
