  xtensa: fix futex_atomic_cmpxchg_inatomic (2018-01-05 15:55:59 -0800)

----------------------------------------------------------------
Xtensa improvements for v4.16:

- 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.

----------------------------------------------------------------
