Merge tag 'xtensa-for-next-20141021-1' of git://github.com/jcmvbkbc/linux-xtensa into for_next 

Xtensa improvements for 3.18:

- add seccomp, getrandom, and memfd_create syscalls;
- add defconfigs for KC705 and SMP LX200;
- fix ISS and xtfpga Kconfig dependencies so that more randconfigs
  are buildable;
- fix umount syscall;
- implement pgprot_noncached.
