ARM: pgtable: invert L_PTE_EXEC to L_PTE_XN
The hardware page tables use an XN bit 'execute never'. Historically, we've had a Linux 'execute allow' bit, in the positive sense. Get rid of this artifact as future hardware will continue to have the XN sense. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
