Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: "Another mixture of changes this time around: - Split XIP linker file from main linker file to make it more maintainable, and various XIP fixes, and clean up a resulting macro. - Decompressor cleanups from Masahiro Yamada - Avoid printing an error for a missing L2 cache - Remove some duplicated symbols in System.map, and move vectors/stubs back into kernel VMA - Various low priority fixes from Arnd - Updates to allow bus match functions to return negative errno values, touching some drivers and the driver core. Greg has acked these changes. - Virtualisation platform udpates form Jean-Philippe Brucker. - Security enhancements from Kees Cook - Rework some Kconfig dependencies and move PSCI idle management code out of arch/arm into drivers/firmware/psci.c - ARM DMA mapping updates, touching media, acked by Mauro. - Fix places in ARM code which should be using virt_to_idmap() so that Keystone2 can work. - Fix Marvell Tauros2 to work again with non-DT boots. - Provide a delay timer for ARM Orion platforms" * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (45 commits) ARM: 8546/1: dma-mapping: refactor to fix coherent+cma+gfp=0 ARM: 8547/1: dma-mapping: store buffer information ARM: 8543/1: decompressor: rename suffix_y to compress-y ARM: 8542/1: decompressor: merge piggy.*.S and simplify Makefile ARM: 8541/1: decompressor: drop redundant FORCE in Makefile ARM: 8540/1: decompressor: use clean-files instead of extra-y to clean files ARM: 8539/1: decompressor: drop more unneeded assignments to "targets" ARM: 8538/1: decompressor: drop unneeded assignments to "targets" ARM: 8532/1: uncompress: mark putc as inline ARM: 8531/1: turn init_new_context into an inline function ARM: 8530/1: remove VIRT_TO_BUS ARM: 8537/1: drop unused DEBUG_RODATA from XIP_KERNEL ARM: 8536/1: mm: hide __start_rodata_section_aligned for non-debug builds ARM: 8535/1: mm: DEBUG_RODATA makes no sense with XIP_KERNEL ARM: 8534/1: virt: fix hyp-stub build for pre-ARMv7 CPUs ARM: make the physical-relative calculation more obvious ARM: 8512/1: proc-v7.S: Adjust stack address when XIP_KERNEL ARM: 8411/1: Add default SPARSEMEM settings ARM: 8503/1: clk_register_clkdev: remove format string interface ARM: 8529/1: remove 'i' and 'zi' targets ...
