Catalin Marinas 8e620b0476 arm64: Distinguish between user and kernel XN bits ... On AArch64, the meaning of the XN bit has changed to UXN (user). The PXN (privileged) bit must be set to prevent kernel execution. Without the PXN bit set, the CPU may speculatively access device memory. This patch ensures that all the mappings that the kernel must not execute from (including user mappings) have the PXN bit set.
