From: Kumar Gala Date: Wed, 22 Jun 2005 00:15:26 +0000 (-0700) Subject: [PATCH] ppc32: Clean up NUM_TLBCAMS usage for Freescale Book-E PPC's X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5be061eee931db2718feecaf10df17610386202b;p=linux-beck.git [PATCH] ppc32: Clean up NUM_TLBCAMS usage for Freescale Book-E PPC's Made the number of TLB CAM entries private and converted the board consumers to use num_tlbcam_entries which is setup at boot time from configuration registers. This way the only consumers of the #define NUM_TLBCAMS are the arrays used to manage the TLB.
