Merge tag 'xtensa-20170507' of git://github.com/jcmvbkbc/linux-xtensa
Pull Xtensa updates from Max Filippov:
- clearly mark references to spilled register locations with SPILL_SLOT
macros
- clean up xtensa ptrace: use generic tracehooks, move internal kernel
definitions from uapi/asm to asm, make locally-used functions static,
fix code style and alignment
- use command line parameters passed to ISS as kernel command line.
