Merge branch 'parisc-3.15-4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc fixes from Helge Deller:
"There are two patches in here:
The first patch greatly improves latency and corrects the memory
ordering in our light-weight atomic locking syscall.
The second patch ratelimits printing of userspace segfaults in the
same way as it's done on other platforms. This fixes a possible DOS
on parisc since it prevents the syslog to grow too fast. For example,
when the debian acl2 package was built on our debian buildd servers,
this package produced lots of gigabytes in syslog in very short time
and thus filled our harddisks, which then turned the server nearly
completely unaccessible and unresponsive"
* 'parisc-3.15-4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: Improve LWS-CAS performance
parisc: ratelimit userspace segfault printing
