Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: "Included in this update: - perf updates from Will Deacon: The main changes are callchain stability fixes from Jean Pihet and event mapping and PMU name rework from Mark Rutland The latter is preparatory work for enabling some code re-use with arm64 in the future. - updates for nommu from Uwe Kleine-König: Two different fixes for the same problem making some ARM nommu configurations not boot since 3.6-rc1. The problem is that user_addr_max returned the biggest available RAM address which makes some copy_from_user variants fail to read from XIP memory. - deprecate legacy OMAP DMA API, in preparation for it's removal. The popular drivers have been converted over, leaving a very small number of rarely used drivers, which hopefully can be converted during the next cycle with a bit more visibility (and hopefully people popping out of the woodwork to help test) - more tweaks for BE systems, particularly with the kernel image format. In connection with this, I've cleaned up the way we generate the linker script for the decompressor. - removal of hard-coded assumptions of the kernel stack size, making everywhere depend on the value of THREAD_SIZE_ORDER. - MCPM updates from Nicolas Pitre. - Make it easier for proper CPU part number checks (which should always include the vendor field). - Assembly code optimisation - use the "bx" instruction when returning from a function on ARMv6+ rather than "mov pc, reg". - Save the last kernel misaligned fault location and report it via the procfs alignment file. - Clean up the way we create the initial stack frame, which is a repeated pattern in several different locations. - Support for 8-byte get_user(), needed for some DRM implementations. - mcs locking from Will Deacon. - Save and restore a few more Cortex-A9 registers (for errata workarounds) - Fix various aspects of the SWP emulation, and the ELF hwcap for the SWP instruction. - Update LPAE logic for pte_write and pmd_write to make it more correct. - Support for Broadcom Brahma15 CPU cores. - ARM assembly crypto updates from Ard Biesheuvel" * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (53 commits) ARM: add comments to the early page table remap code ARM: 8122/1: smp_scu: enable SCU standby support ARM: 8121/1: smp_scu: use macro for SCU enable bit ARM: 8120/1: crypto: sha512: add ARM NEON implementation ARM: 8119/1: crypto: sha1: add ARM NEON implementation ARM: 8118/1: crypto: sha1/make use of common SHA-1 structures ARM: 8113/1: remove remaining definitions of PLAT_PHYS_OFFSET from <mach/memory.h> ARM: 8111/1: Enable erratum 798181 for Broadcom Brahma-B15 ARM: 8110/1: do CPU-specific init for Broadcom Brahma15 cores ARM: 8109/1: mm: Modify pte_write and pmd_write logic for LPAE ARM: 8108/1: mm: Introduce {pte,pmd}_isset and {pte,pmd}_isclear ARM: hwcap: disable HWCAP_SWP if the CPU advertises it has exclusives ARM: SWP emulation: only initialise on ARMv7 CPUs ARM: SWP emulation: always enable when SMP is enabled ARM: 8103/1: save/restore Cortex-A9 CP15 registers on suspend/resume ARM: 8098/1: mcs lock: implement wfe-based polling for MCS locking ARM: 8091/2: add get_user() support for 8 byte types ARM: 8097/1: unistd.h: relocate comments back to place ARM: 8096/1: Describe required sort order for textofs-y (TEXT_OFFSET) ARM: 8090/1: add revision info for PL310 errata 588369 and 727915 ...
