Merge tag 'xtensa-20180129' of git://github.com/jcmvbkbc/linux-xtensa

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()
