Merge git://git.kernel.org/pub/scm/linux/kernel/git/kyle/parisc-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/kyle/parisc-2.6: parisc: convert to generic compat_sys_ptrace parisc: add rtc platform driver parisc: initialize unwinder much earlier parisc: add new syscalls parisc: hijack jump to start_kernel parisc: add pdc_coproc_cfg_unlocked and set_firmware_width_unlocked parisc: move include/asm-parisc to arch/parisc/include/asm parisc: move pdc_result to real2.S parisc: unify CCIO_COLLECT_STATS implementation parisc: add arch/parisc/kernel/.gitignore parisc: ropes.h - fix <asm-parisc/*> -> <asm/*> parisc: parisc-agp - fix <asm-parisc/*> -> <asm/*> Resolve remove/rename conflict: include/asm-parisc/a.out.h is no longer relevant.
