[ARM] Improve non-executable support 2008-10-01T15:41:10+00:00 Russell King rmk@dyn-67.arm.linux.org.uk 2008-09-07T16:16:54+00:00 8ec53663d2698076468b3e1edc4e1b418bd54de3 Add support for detecting non-executable stack binaries, and adjust permissions to prevent execution from data and stack areas. Also, ensure that READ_IMPLIES_EXEC is enabled for older CPUs where that is true, and for any executable-stack binary. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] Remove MT_DEVICE_IXP2000 and associated definitions 2008-10-01T15:41:06+00:00 Russell King rmk@dyn-67.arm.linux.org.uk 2008-09-07T11:42:51+00:00 db5b7169474882fabbd811a4cf5c1bae3157e677 As of the previous commit, MT_DEVICE_IXP2000 encodes to the same PTE bit encoding as MT_DEVICE, so it's now redundant. Convert MT_DEVICE_IXP2000 to use MT_DEVICE instead, and remove its aliases. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] Introduce new PTE memory type bits 2008-10-01T15:40:56+00:00 Russell King rmk@dyn-67.arm.linux.org.uk 2008-09-06T19:04:59+00:00 bb30f36f9b71c31dc8fe3483bba4c9884fc86080 Provide L_PTE_MT_xxx definitions to describe the memory types that we use in Linux/ARM. These definitions are carefully picked such that: 1. their LSBs match what is required for pre-ARMv6 CPUs. 2. they all have a unique encoding, including after modification by build_mem_type_table() (the result being that some have more than one combination.)
