From 3461b0af025251bbc6b3d56c821c6ac2de6f7209 Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Mon, 12 May 2008 21:21:13 +0200 Subject: x86: remove static boot_cpu_pda array v2 * Remove the boot_cpu_pda array and pointer table from the data section. Allocate the pointer table and array during init. do_boot_cpu() will reallocate the pda in node local memory and if the cpu is being brought up before the bootmem array is released (after_bootmem = 0), then it will free the initial pda. This will happen for all cpus present at system startup. This removes 512k + 32k bytes from the data section. For inclusion into sched-devel/latest tree.
