Merge branch 'parisc-4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller:
- Add native high-resolution timing code for sched_clock() and other
timing functions based on the processor internal cr16 cycle counters
- Add syscall tracepoint support
- Add regset support
- Speed up get_user() and put_user() functions
- Updated futex.h to match generic implementation (John David Anglin)
- A few smaller ftrace build fixes
- Fixed thuge-gen kernel self test to utilize architectured MAP_HUGETLB
value
- Added parisc architecture to seccomp_bpf kernel self test
- Various typo fixes (Andrea Gelmini)
