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"
