Merge branch 'parisc-5.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller: "Many great new features, fixes and optimizations, including: - Convert page table updates to use per-pagetable spinlocks which overall improves performance on SMP machines a lot, by Mikulas Patocka - Kernel debugger (KGDB) support, by Sven Schnelle - KPROBES support, by Sven Schnelle - Lots of TLB lock/flush improvements, by Dave Anglin - Drop DISCONTIGMEM and switch to SPARSEMEM - Added JUMP_LABEL, branch runtime-patching support - Lots of other small speedups and cleanups, e.g. for QEMU, stack randomization, avoidance of name clashes, documentation updates, etc ..." * 'parisc-5.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: (28 commits) parisc: Add static branch and JUMP_LABEL feature parisc: Use PA_ASM_LEVEL in boot code parisc: Rename LEVEL to PA_ASM_LEVEL to avoid name clash with DRBD code parisc: Update huge TLB page support to use per-pagetable spinlock parisc: Use per-pagetable spinlock parisc: Allow live-patching of __meminit functions parisc: Add memory barrier to asm pdc and sync instructions parisc: Add memory clobber to TLB purges parisc: Use ldcw instruction for SMP spinlock release barrier parisc: Remove lock code to serialize TLB operations in pacache.S parisc: Switch from DISCONTIGMEM to SPARSEMEM parisc: enable wide mode early parisc: update feature lists parisc: Show n/a if product number not available parisc: remove unused flags parameter in __patch_text() doc: update kprobes supported architecture list parisc: Implement kretprobes parisc: remove kprobes.h from generic-y parisc: Implement kprobes parisc: add functions required by KPROBE_EVENTS ...
