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
