One TODO in this port compared to x86 is the uprobe abort_xol() logic.
x86 depends on
oopses. This means we might miss multiple CPUs oopsing at exactly
the same time but I think it's best to play it safe for now. Once we
are happy with the reliability we can change it to a full spinlock.

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().

Jim Keniston (6):
Shrink our zlib_deflate workspace from 268K to 24K
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.)
