[SPARC64]: Probe D/I/E-cache config and use.
At boot time, determine the D-cache, I-cache and E-cache size and
line-size. Use them in cache flushes when appropriate.
This change was motivated by discovering that the D-cache on
UltraSparc-IIIi and later are 64K not 32K, and the flushes done by the
Cheetah error handlers were assuming a 32K size.
There are still some pieces of code that are hard coding things and
will need to be fixed up at some point.
While we're here, fix the D-cache and I-cache parity error handlers
to run with interrupts disabled, and when the trap occurs at trap
level > 1 log the event via a counter displayed in /proc/cpuinfo.
