The VMSA field of MMFR0 (bottom 4 bits) is incremented for each added feature. PXN is supported if the value is >= 4 and LPAE is supported if it is >= 5. In case a kernel with CONFIG_ARM_LPAE disabled is used on a processor that supports LPAE, we can still use PXN in short descriptors. So check for >= 4 not == 4.
