Merge branch 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King:
- Initial round of Spectre variant 1 and variant 2 fixes for 32-bit ARM
- Clang support improvements
- nommu updates for v8 MPU
- enable ARM_MODULE_PLTS by default to avoid problems loading modules
with larger kernels
- vmlinux.lds and dma-mapping cleanups
