	syssrc/sys/arch/sparc/sparc: cache.c cache.h cpu.c cpuvar.h pmap.c

Log Message:
Re-arrange code to flush physically indexed caches:

* replace `flush by line' function with a `flush by page' funtion, which
  also takes an argument to indicate that write-back caches need not
  validate its backing memory.

* use this function when allocating page table memory to flush the cache
  before mapping it into kernel virtual space.

* also use it in pmap_{zero,copy}_page(), so we can safely use non-cacheable
  access in there.
