From 6fd8be4bf72879b3039654388e985cabf8449af5 Mon Sep 17 00:00:00 2001 From: Trent Piepho Date: Mon, 8 Dec 2008 19:34:56 -0800 Subject: powerpc/fsl-booke: Remove num_tlbcam_entries This is a global variable defined in fsl_booke_mmu.c with a value that gets initialized in assembly code in head_fsl_booke.S. It's never used. If some code ever does want to know the number of entries in TLB1, then "numcams = mfspr(SPRN_TLB1CFG) & 0xfff", is a whole lot simpler than a global initialized during kernel boot from assembly.
