Merge branch 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King:
- add support for ELF fdpic binaries on both MMU and noMMU platforms
- linker script cleanups
- support for compressed .data section for XIP images
- discard memblock arrays when possible
- various cleanups
- atomic DMA pool updates
- better diagnostics of missing/corrupt device tree
- export information to allow userspace kexec tool to place images more
inteligently, so that the device tree isn't overwritten by the
booting kernel
- make early_printk more efficient on semihosted systems
- noMMU cleanups
- SA1111 PCMCIA update in preparation for further cleanups
