Merge master.kernel.org:/pub/scm/linux/kernel/git/kyle/parisc-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/kyle/parisc-2.6: (78 commits) [PARISC] Use symbolic last syscall in __NR_Linux_syscalls [PARISC] Add missing statfs64 and fstatfs64 syscalls Revert "[PARISC] Optimize TLB flush on SMP systems" [PARISC] Compat signal fixes for 64-bit parisc [PARISC] Reorder syscalls to match unistd.h Revert "[PATCH] make kernel/signal.c:kill_proc_info() static" [PARISC] fix sys_rt_sigqueueinfo [PARISC] fix section mismatch warnings in harmony sound driver [PARISC] do not export get_register/set_register [PARISC] add ENTRY()/ENDPROC() and simplify assembly of HP/UX emulation code [PARISC] convert to use CONFIG_64BIT instead of __LP64__ [PARISC] use CONFIG_64BIT instead of __LP64__ [PARISC] add ASM_EXCEPTIONTABLE_ENTRY() macro [PARISC] more ENTRY(), ENDPROC(), END() conversions [PARISC] fix ENTRY() and ENDPROC() for 64bit-parisc [PARISC] Fixes /proc/cpuinfo cache output on B160L [PARISC] implement standard ENTRY(), END() and ENDPROC() [PARISC] kill ENTRY_SYS_CPUS [PARISC] clean up debugging printks in smp.c [PARISC] factor syscall_restart code out of do_signal ... Fix conflict in include/linux/sched.h due to kill_proc_info() being made publicly available to PARISC again.
