Merge branch 'parisc-3.9' of git://
Pull parisc updates from Helge Deller. The bulk of this is optimized page coping/clearing and cache flushing (virtual caches are lovely) by John David Anglin. * 'parisc-3.9' of git:// (31 commits) arch/parisc/include/asm: use ARRAY_SIZE macro in mmzone.h parisc: remove empty lines and unnecessary #ifdef coding in include/asm/signal.h parisc: sendfile and sendfile64 syscall cleanups parisc: switch to available compat_sched_rr_get_interval implementation parisc: fix fallocate syscall parisc: fix error return codes for rt_sigaction and rt_sigprocmask parisc: convert msgrcv and msgsnd syscalls to use compat layer parisc: correctly wire up mq_* functions for CONFIG_COMPAT case parisc: fix personality on 32bit kernel parisc: wire up process_vm_readv, process_vm_writev, kcmp and finit_module syscalls parisc: led driver requires CONFIG_VM_EVENT_COUNTERS parisc: remove unused compat_rt_sigframe.h header parisc/mm/fault.c: Port OOM changes to do_page_fault parisc: space register variables need to be in native length (unsigned long) parisc: fix ptrace breakage parisc: always detect multiple physical ranges parisc: ensure that mmapped shared pages are aligned at SHMLBA addresses parisc: disable preemption while flushing D- or I-caches through TMPALIAS region parisc: remove IRQF_DISABLED parisc: fixes and cleanups in page cache flushing (4/4) ...

+ help
+ If you configure the kernel to include many drivers built-in instead
+ as modules, the kernel executable may become too big, so that the
+ linker will not be able to resolve some long branches and fails to link
+ your vmlinux kernel. In that case enabling this option will help you
+ to overcome this limit by using the -mlong-calls compiler option.
+ Usually you want to say N here, unless you e.g. want to build
+ a kernel which includes all necessary drivers built-in and which can
+ be used for TFTP booting without the need to have an initrd ramdisk.
+ Enabling this option will probably slow down your kernel.
