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.
