Enable virtual caching for kernel pages.  When we enabled virtual caching
for certain user pages, stores to kernel pages would not update the
affected cache lines, which would sometimes cause the wrong data to be
returned for loads from kernel pages.  This was especially fatal when
the addresses affected held the kernel stack pointer, and a random
value was loaded into it.
Fix a harmless off by one error in a dcache_inval_phys call.
