Capture more than twice as much text from the printk buffer, and
compress it to fit it in the lnx,oops-log NVRAM partition. You
can view the compressed text using the new (as of July 20) --unzip
option of the nvram command in the powerpc-utils package.

For normal halt, reboot, and poweroff events, refrain from overwriting
the lnx,oops-log partition. Also, don't save the dmesg buffer on an
emergency-restart event if we've already saved it earlier in panic().

Here's a patch to the nvram command t
workspace is a win because our choices are to allocate
the workspace when we need it (i.e., during an oops or panic) or
allocate it at boot time. (We do the latter.)

The *_arg and [u_]register functions are described in the stapfuncs man
page (but not in the Language Reference doc).
testsuite/systemtap.context/num_args.tcl tests some of these functions
(or used to, at least).
