Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King:
- Fix BSS size calculation for LLVM
- Improve robustness of kernel entry around v7_invalidate_l1
- Fix and update kprobes assembly
- Correct breakpoint overflow handler check
- Pause function graph tracer when suspending a CPU
- Switch to generic syscallhdr.sh and syscalltbl.sh
- Remove now unused set_kernel_text_r[wo] functions
- Updates for ptdump (__init marking and using DEFINE_SHOW_ATTRIBUTE)
- Fix for interrupted SMC (secure) calls
- Remove Compaq Personal Server platform
