[Xen-devel] [PATCH v3 04/10] Make MEM_ACCESS configurable

2018-05-22 Thread Stefano Stabellini
Have arm and x86 select HAS_MEM_ACCESS to mark that they can do MEM_ACCESS. Select an additional MEM_ACCESS_ALWAYS_ON on x86 to mark that MEM_ACCESS is not configurable on x86. Rename HAS_MEM_ACCESS to MEM_ACCESS everywhere else. Add a prompt and a description to MEM_ACCESS in xen/common/Kconfig.
