powerpc/nvram: Add compression to fit more oops output into NVRAM
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.
