[PARISC] Delete arch/parisc/mm/kmap.c again
Matthew Wilcox [Fri, 13 Oct 2006 18:32:50 +0000 (12:32 -0600)]
I deleted this file from 2.4 5 years ago.  Unfortunately, that change
never got merged to Linus and so when we switched to 2.5 it came back
and nobody noticed.  It's never been built in 2.5/2.6 as it was never
in the Makefile.
