From d30f9043539d372cf66406bc2f21bb8c20e67009 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Fri, 11 Sep 2009 11:27:00 -0500 Subject: ppc/85xx: Introduce low level write_tlb function Factor out the code we use to actually write a tlb entry. set_tlb is a logical view of the TLB while write_tlb is a low level matching the MAS registers.
