Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: - An improvement from Ard Biesheuvel, who noted that the identity map setup was taking a long time due to flush_cache_louis(). - Update a comment about dma_ops from Wolfram Sang. - Remove use of "-p" with ld, where this flag has been a no-op since 2004. - Remove the printing of the virtual memory layout, which is no longer useful since we hide pointers. - Correct SCU help text. - Remove legacy TWD registration method. - Add pgprot_device() implementation for mapping PCI sysfs resource files. - Initialise PFN limits earlier for kmemleak. - Fix argument count to match macro definition (affects clang builds) - Use unified assembler language almost everywhere for clang, and other clang improvements (from Stefan Agner, Nathan Chancellor). - Support security extension for noMMU and other noMMU cleanups (from Vladimir Murzin). - Remove unnecessary SMP bringup code (which was incorrectly copy'n' pasted from the ARM platform implementations) and remove it from the arch code to discourge further copys of it appearing. - Add Cortex A9 erratum preventing kexec working on some SoCs. - AMBA bus identification updates from Mike Leach. - More use of raw spinlocks to avoid -RT kernel issues (from Yang Shi and Sebastian Andrzej Siewior). - MCPM hyp/svc mode mismatch fixes from Marek Szyprowski. * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: (32 commits) ARM: 8849/1: NOMMU: Fix encodings for PMSAv8's PRBAR4/PRLAR4 ARM: 8848/1: virt: Align GIC version check with arm64 counterpart ARM: 8847/1: pm: fix HYP/SVC mode mismatch when MCPM is used ARM: 8845/1: use unified assembler in c files ARM: 8844/1: use unified assembler in assembly files ARM: 8843/1: use unified assembler in headers ARM: 8841/1: use unified assembler in macros ARM: 8840/1: use a raw_spinlock_t in unwind ARM: 8839/1: kprobe: make patch_lock a raw_spinlock_t ARM: 8837/1: coresight: etmv4: Update ID register table to add UCI support ARM: 8836/1: drivers: amba: Update component matching to use the CoreSight UCI values.
