From 679bea5e438df70b5d4348fd2da4501aaeacebe0 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 13 May 2012 13:23:16 -0700 Subject: sparc: Kill mmu_{un,}lockarea(). These were used on sun4c during floppy data transfers since on that chip we had to lock the cpu mappings into the TLB because we cannot take a TLB miss during the assembler floppy interrupt handler that does the data transfer. That is no longer necessary since we've removed sun4c support, thus this stuff can disappear completely. Signed-off-by: David S.
