[PATCH v2 14/22] ARM: LPAE: accomodate >32-bit addresses for page table base

This patch redefines the early boot time use of the R4 register to steal a few low order bits (ARCH_PGD_SHIFT bits) on LPAE systems. This allows for up to 38-bit physical addresses. Signed-off-by: Cyril Chemparathy Signed-off-by: Vitaly Andrianov --- arch/arm/include/asm/memory.h | 15
