Merge tag 'xtensa-for-next-20150304' of git://github.com/jcmvbkbc/linux-xtensa into for_next
Xtensa fixes for 4.0:
- make xtfpgs LCD driver functional and configurable. This fixes hardware
lockup on KC705/ML605 boot;
- wire bpf and execveat syscalls;
- provide __NR_sync_file_range2 instead of __NR_sync_file_range, as that's
what xtensa uses.
