x86: Make 64 bit use early_res instead of bootmem before slab
Finally we can use early_res to replace bootmem for x86_64 now. Still can use CONFIG_NO_BOOTMEM to enable it or not. -v2: fix 32bit compiling about MAX_DMA32_PFN -v3: folded bug fix from LKML message below Signed-off-by: Yinghai Lu <yinghai@kernel.org> LKML-Reference: <4B747239.4070907@kernel.org> Signed-off-by: H.
