[PATCH 07/37] lmb: Add lmb_find_area()
it is a wrapper for lmb_find_base make it more easy for x86 to use lmb. ( rebase ) x86 early_res is using find/reserve pattern instead of alloc. keep it in weak version, so later We can use x86 own version if needed. also We need it in lib/lmb.c, so one called mm/page_alloc.c could get compiled -v2: Change n... 14 May 2010 16:07

[PATCH 13/37] x86, lmb: Add lmb_register_active_regions() and lmb_hole_size()

It will be used lmb_to_bootmem converting It is an wrapper for reserve_bootmem, and x86 64bit is using special one. Also clean up that version for x86_64.
