Memory protection keys enable applications to protect its address space from
inadvertent access from itself.
This feature is now enabled on powerpc architecture. The patches move the
selftests to arch neutral directory and enhances them. Verified for correctness
on powerpc and on x86 architectures(using EC2 ubuntu VM instances).
Ram Pai (21):
selftests/x86: Move protecton key selftest to arch neutral directory
selftests/vm: rename all references to pkru to a generic name
selftests/vm: move generic definitions to header file
selftests/vm: typecast the pkey register
selftests/vm: generic function to handle shadow key register
selftests/vm: fix the wrong assert in pkey_disable_set()
selftests/vm: fixed bugs in pkey_disable_clear()
selftests/vm: clear the bits in shadow reg when a pkey is freed.
selftests/vm: fix alloc_random_pkey() to make it really random
selftests/vm: introduce two arch independent abstraction
selftests/vm: pkey register should match shadow pkey
selftests/vm: generic cleanup
selftests/vm: powerpc implementation for generic abstraction
selftests/vm: clear the bits in shadow reg when a pkey is freed.
selftests/vm: powerpc implementation to check support for pkey
selftests/vm: fix an assertion in test_pkey_alloc_exhaust()
selftests/vm: associate key on a mapped page and detect access
violation
selftests/vm: associate key on a mapped page and detect write
violation
selftests/vm: detect write violation on a mapped access-denied-key
page
selftests/vm: testcases must restore pkey-permissions
selftests/vm: sub-page allocator
