Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm

Pull ARM updates from Russell King:

 - remove a now unnecessary usage of the KERNEL_DS for
   sys_oabi_epoll_ctl()

 - update my email address in a number of drivers

 - decompressor EFI updates from Ard Biesheuvel

 - module unwind section handling updates

 - sparsemem Kconfig cleanups

 - make act_mm macro respect THREAD_SIZE
