The working flow of new feature is:
->bootloader decompress ramdisk.gz to cpio data first and start kernel.
->decompressor driver notify initramfs that cpio data ready.
->initramfs continue to flush cpio data to rootfs.

In memmap_init_zone, it check all pages valid or deffered by single page,
then zero and init the corresponding page struct. It is safe to zero all
page struct in advance at once no matter what the state of every page is.
This can save time when booting kernel.

hw_random driver depends on hwrng_modinit() to init first.
But driver initcall and hwrng_modinit() are both in the same
device_init level.
Fix this by move hwrng_modinit() to the rootfs_initcall level.

rfkill_init() depends on misc_init() to init misc_class.
But rfkill_init() and misc_init() are both in the same

Fix this by move misc_init() to the arch_initcall_sync level.
