Merge branch 'parisc-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller:
"There are two major changes in this patchset:
The major fix is that the epoll_pwait() syscall for 32bit userspace
was not using the compat wrapper on a 64bit kernel.
Secondly we changed the value of SHMLBA from 4MB to PAGE_SIZE to
reflect that we can actually mmap to any multiple of PAGE_SIZE. The
only thing which needs care is that shared mmaps need to be mapped at
the same offset inside the 4MB cache window"
* 'parisc-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: fix epoll_pwait syscall on compat kernel
parisc: change value of SHMLBA from 0x00400000 to PAGE_SIZE
parisc: Replace __get_cpu_var uses for address calculation
