Instead of using bootmem, try find_e820_area()/reserve_early(),
and call acpi_reserve_memory() early, to allocate the wakeup
trampoline code area below 1M.
This is more reliable, and it also removes a dependency on
bootmem.
-v2: change function name to acpi_reserve_wakeup_memory(),
as suggested by Rafael.
