00100b0eec Use get_pcpu() instead of using pcpup, as it's wrong for SMP.

5ac74cc6e4 Remove the unused field "pc_prvspace" from the MD fields for the struct 
pcpu. There's not even a thing such as a "struct pcup".
While I'm there, remove a comment that makes no sense for arm.

70d12a18f2 Export 'struct pcpu' to userland w/o requiring _KERNEL. A few ports 
already define _KERNEL to get to this and I'm about to add hooks to
libkvm to access per-CPU data.

6759608248 Rework the PCPU_* (MD) interface: 
- Rename PCPU_LAZY_INC into PCPU_INC
- Add the PCPU_ADD interface which just does an add on the pcpu member
  given a specific value.

Note that for most architectures PCPU_INC and PCPU_ADD are not safe.
This is a point that needs some discussions/work in the next days.

c640357f04 Push down the implementation of PCPU_LAZY_INC() into the machine-dependent 
header file.  Reimplement PCPU_LAZY_INC() on amd64 and i386 making it
atomic with respect to interrupts.

6fc729af63 Import FreeBSD/arm kernel bits. 
It only supports sa1110 (on simics) right now, but xscale support should come
soon.
Some of the initial work has been provided by :
Stephane Potvin <sepotvin at videotron.ca>
Most of this comes from NetBSD.
