Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: - fix various clang build and cppcheck issues - switch ARM to use new common outgoing-CPU-notification code - add some additional explanation about the boot code - kbuild "make clean" fixes - get rid of another "(____ptrval____)", this time for the VDSO code - avoid treating cache maintenance faults as a write - add a frame pointer unwinder implementation for clang - add EDAC support for Aurora L2 cache - improve robustness of adjust_lowmem_bounds() finding the bounds of lowmem. - add reset control for AMBA primecell devices * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: (24 commits) ARM: 8906/1: drivers/amba: add reset control to amba bus probe ARM: 8905/1: Emit __gnu_mcount_nc when using Clang 10.0.0 or newer ARM: 8904/1: skip nomap memblocks while finding the lowmem/highmem boundary ARM: 8903/1: ensure that usable memory in bank 0 starts from a PMD-aligned address ARM: 8891/1: EDAC: armada_xp: Add support for more SoCs ARM: 8888/1: EDAC: Add driver for the Marvell Armada XP SDRAM and L2 cache ECC ARM: 8892/1: EDAC: Add missing debugfs_create_x32 wrapper ARM: 8890/1: l2x0: add marvell,ecc-enable property for aurora ARM: 8889/1: dt-bindings: document marvell,ecc-enable binding ARM: 8886/1: l2x0: support parity-enable/disable on aurora ARM: 8885/1: aurora-l2: add defines for parity and ECC registers ARM: 8887/1: aurora-l2: add prefix to MAX_RANGE_SIZE ARM: 8902/1: l2c: move cache-aurora-l2.h to asm/hardware ARM: 8900/1: UNWINDER_FRAME_POINTER implementation for Clang ARM: 8898/1: mm: Don't treat faults reported from cache maintenance as writes ARM: 8896/1: VDSO: Don't leak kernel addresses ARM: 8895/1: visit mach-* and plat-* directories when cleaning ARM: 8894/1: boot: Replace open-coded nop with macro ARM: 8893/1: boot: Explain the 8 nops ARM: 8876/1: fix O= building with CONFIG_FPE_FASTFPE ...

This option allows for the kernel to be compiled using the latest
ARM ABI (aka EABI). This is only useful if you are using a user
