	help
	  This feature enables 64KB pages support (4KB by default)
	  allowing only two levels of page tables and faster TLB
	  look-up. AArch32 emulation is not available when this feature
	  is enabled.

	help
	  This enables support for systems with more than one CPU.  If
	  you say N here, the kernel will run on single and
	  multiprocessor machines, but will use only one CPU of a
	  multiprocessor machine. If you say Y here, the kernel will run
	  on many, but not all, single processor machines. On a single
	  processor machine, the kernel will run faster if you say N
	  here.

	  If you don't know what to do here, say N.

	  root device (e.g. root=/dev/nfs).

config CMDLINE_FORCE
	bool "Always use the default kernel command string"
	help
	  Always use the default kernel command string, even if the boot
	  loader passes other arguments to the kernel.
	  This is useful if you cannot or don't want to change the
	  command-line options your boot loader passes to the kernel.

	  kernel at EL1. AArch32-specific components such as system calls,
	  the user helper functions, VFP support and the ptrace interface are
	  handled appropriately by the kernel.
