Pull Xtensa updates from Max Filippov:
- add SSP support
- add KASAN support
- improvements to xtensa-specific assembly:
- use ENTRY and ENDPROC consistently
- clean up and unify word alignment macros
- clean up and unify fixup marking
- use 'call' instead of 'callx' where possible
- various cleanups:
- consiolidate kernel stack size related definitions
- replace #ifdef'fed/commented out debug printk statements with
pr_debug
- use struct exc_table instead of flat array for exception handling
data
- build kernel with -mtext-section-literals; simplify xtensa linker
script
- fix futex_atomic_cmpxchg_inatomic()
