Merge branch 'parisc-4.9-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller: "The first three patches are trivial and add some required KERN_CONT, ignore the new pkey syscalls on parisc and use the LINUX_GATEWAY_ADDR define instead of hardcoded values. The two patches from Dave Anglin are important. The first one avoids trashing the sr2 and sr3 space registers in the Light-weight syscall path. Especially the usage of sr3 is critical since it may get trashed by the interrupt handler. The second patch is even more important and tagged for stable series. It protects one critical section in the syscall entry path by disabling local interrupts. Without disabling interrupts, the sr7 space register may not be in sync with the current stack setup and thus an incoming hardware interrupt may destroy memory in random userspace areas" * 'parisc-4.9-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Ignore the pkey system calls for now parisc: Use LINUX_GATEWAY_ADDR define instead of hardcoded value parisc: Ensure consistent state when switching to kernel stack at syscall entry parisc: Avoid trashing sr2 and sr3 in LWS code parisc: use KERN_CONT when printing device inventory
