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. Based on: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git + sched-devel/latest .../mingo/linux-2.6-sched-devel.git Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
