Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Michael Ellerman, Linus Torvalds
From: Laurent Dufour <redacted> Set ARCH_SUPPORTS_PER_VMA_LOCK so that the per-VMA lock support can be compiled on powernv and pseries. It may be use on the other platforms but I can't test that seriously.
