Justin Hibbits cbc3c68d9a Add a kdb show command to print arbitrary SPRs on PowerPC
Summary:
There is often a need at the debugger to print arbitrary special
purpose registers (SPRs) on PowerPC.  Using a rewritable asm stub, print any SPR
provided on the command line.

Note, as there is no checking in this, attempting to print a nonexistent SPR
may cause a Program exception (illegal instruction, or boundedly undefined).

Note also that this relies on the kernel text pages being writable.  If in the
future this is made not the case, this will need to be reworked.

Test Plan:
Printing the Processor Version Register (PVR, SPR 287):

db> show spr 11f
SPR 287(11f): 80240012

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree.  See build(7)
and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
for more information, including setting make(1) variables.

The `buildkernel` and `installkernel` targets build and install
the kernel and the modules (see below).  Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process.  See build(7), config(8),
and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
for more information.

Note: If you want to build and install the kernel with the
`buildkernel` and `installkernel` targets, you might need to build
world before.  More information is available in the handbook.

The kernel configuration files reside in the sys/<arch>/conf
sub-directory.  GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
devices, not just those commonly used.
