	config TLS_REG_EMUL

	An SMP system using a pre-ARMv6 processor (there are apparently
	a few prototypes like that in existence) and therefore access to

	This selects support for the CP15 thread register.
	It is defined to be available on some ARMv6 processors (including
	all SMP capable ARMv6's) or later processors. User space may
	assume directly accessing that register and always obtain the
	expected value only on ARMv7 and above.

	config NEEDS_SYSCALL_FOR_CMPXCHG
	bool
	help
	SMP on a pre-ARMv6 processor? Well OK then.
	Forget about fast user space cmpxchg support.
	It is just not possible.

	This option enables the L2x0 PrimeCell.
