Linus Torvalds d0bd31dc5c 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.
