Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rmk/linux

Pull ARM updates from Russell King:

 - Updates to AMBA bus subsystem to drop .owner struct device_driver
   initialisations, moving that to code instead.

 - Add LPAE privileged-access-never support

 - Add support for Clang CFI

 - clkdev: report over-sized device or connection strings
