[PATCH] Reduce size of huge boot per_cpu_pageset
Reduce size of the huge per_cpu_pageset structure in __initdata introduced
into mm1 with the pageset localization patchset. Use one specially
configured pageset per cpu for all zones and nodes during bootup.
- Avoid duplication of pageset initialization code.
- do the adding to the pageset list before potential free_pages_bulk
in free_hot_cold_page (otherwise we would have to hold a page
in a pageset during the period that the boot pagesets are in use).
- remove mistaken __cpuinitdata attribute and revert back to __initdata
for the boot pageset. A boot pageset is not necessary for cpu hotplug.
Tested for UP SMP NUMA on x86_64 (2.6.12-rc6-mm1): UP SMP NUMA Tested on
IA64 (2.6.12-rc5-mm2): NUMA (2.6.12-rc6-mm1 broken for IA64 because of
sparsemem patches)
