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.

+ * is free.  You can't be sure no more interrupts are being
+ * serviced until you've acquired the lock and then checked
+ * all the per-cpu interrupt counts are all zero.  It's a specialised
+ * br_lock, and that's exactly how Sparc does it.  We don't because
+ * it's more locking for us.  This way is lock-free in the interrupt path.

+**
+** While I'm at it more PA programming notes:
+**
+** 1) MMIO stores (writes) are posted operations. This means the processor

+**    force in-flight write transaction(s) out to the targeted device
+**    before the read can complete.
+**
+** 2) The Programmed I/O (PIO) data may not always be strongly ordered with
+**    respect to DMA on all platforms. Ie PIO data can reach the processor
+**    before in-flight DMA reaches memory. Since most SMP PA platforms
+**    are I/O coherent, it generally doesn't matter...but sometimes
+**    it does.
+**
+** I've helped device driver writers debug both types of problems.

+** PA-RISC architecture allows for weakly ordered memory accesses although
