x86, mm: Move reserving low memory later in initialization Move the reservation of low memory, except for the 4K which actually does belong to the BIOS, later in the initialization; in particular, after we have already reserved the trampoline. The current code locates the trampoline as high as possible, so by deferring the allocation we will still be able to reserve as much memory as is possible. This allows us to run with reservelow=640k without getting a crash on system startup. Signed-off-by: H.
