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
