ARM: LPAE: Add the Kconfig entries
This patch adds the ARM_LPAE and ARCH_PHYS_ADDR_T_64BIT Kconfig entries allowing LPAE support to be compiled into the kernel. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

Say Y if you have an ARMv7 processor supporting the LPAE page

||||||
|
table format and you would like to access memory beyond the
|
||||||
|
4GB limit. The resulting kernel image will not run on
|
||||||
|
processors without the LPA extension.
|

|

If unsure, say N.
