[PATCH 26/39] nobootmem: use lmb.default_alloc_limit in alloc_bootmem path

[Yinghai Lu]

Generic version __lmb_find_area() is going from high to low, and for 32bit
active_region for 32bit does include high pages

need to replace the limit with lmb.default_alloc_limit, aka get_max_mapped()

with this patch, x86 32bit could use generic version of __lmb_find_area()
