Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: - Add a "cut here" to make it clearer where oops dumps should be cut from - we already have a marker for the end of the dumps. - Add logging severity to show_pte() - Drop unnecessary common-page-size linker flag - Errata workarounds for Cortex A12 857271, Cortex A17 857272 and Cortex A7 814220. - Remove some unused variables that had started to provoke a compiler warning. * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: 8863/1: stm32: select ARM errata 814220 ARM: 8862/1: errata: 814220-B-Cache maintenance by set/way operations can execute out of order ARM: 8865/1: mm: remove unused variables ARM: 8864/1: Add workaround for I-Cache line size mismatch between CPU cores ARM: 8861/1: errata: Workaround errata A12 857271 / A17 857272 ARM: 8860/1: VDSO: Drop implicit common-page-size linker flag ARM: arrange show_pte() to issue severity-based messages ARM: add "8<--- cut here ---" to kernel dumps
