Subject: [PATCH 4/5] x86, defconfig: Turn off CONFIG_BLK_DEV_RAM

The vast majority of systems either use initramfs or mount a root
filesystem directly from the kernel.  Distros have defaulted to
initramfs for years.  Only highly specialized systems would use an
actual filesystem-image initrd at this point, and such systems don't
rely on defconfig anyway.  Drop initrd support (and specifically RAM
block device support) from the defconfigs.
