The main patch is 3/3, and describes the details in its commit message. Patch 1/3 prepares for patch 2/3, which is prep for 3/3, and also fixes a potential problem with checking access permissions on v6 processors when they use the simple AP format. Changes since v1: * There are now 3 patches instead of 5. This is due to approaching the prep patches in a different way. Most notably, simple AP format is now handled with its own function. [Peter Maydell] * A check of SCTLR_AFE is guarded with ARM_FEATURE_V6K [Peter Maydell] * All other cleanups suggested by Peter Maydell. Tested by booting Linux on mach-virt with cortex-a15 and cortex-a57 (just up to 'Unable to mount root fs'), and also with a kvm-unit-tests test. The curious can check out the unit test here [1].
