Linus Torvalds 05bdb8c90e Xtensa improvements for 3.17:
- support highmem on cores with aliasing data cache. Enable highmem on kc705
   by default;
 - simplify addition of new core variants (no need to modify Kconfig /
   Makefiles);
 - improve robustness of unaligned access handler and its interaction with
   window overflow/underflow exception handlers;
 - deprecate atomic and spill registers syscalls;
 - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select' statements;
 - wire up renameat2 syscall.
 
 Various fixes:
 - fix address checks in dma_{alloc,free}_coherent (runtime BUG);
 - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage);
 - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss (runtime
   unrecoverable exception);
 - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace register
   clobbering);
 - fix kernel/user jump out of fast_unaligned (potential runtime unrecoverabl
   exception);
 - replace termios IOCTL code definitions with constants (userspace build
   breakage).
