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.
