#     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
#
