2015-03-06arm64: Don't use is_module_addr in setting page attributesLaura Abbott
The set_memory_* functions currently only support module addresses. The addresses are validated using is_module_addr. That function is special though and relies on internal state in the module subsystem to work properly. At the time of module initialization and calling set_memory_*, it's too early for is_module_addr to work properly so it always returns false. Rather than be subject to the whims of the module state, just bounds check against the module virtual address range.

2014-09-12arm64: pageattr: Correctly adjust unaligned start addressesLaura Abbott
The start address needs to be actually updated after it is detected to be unaligned. Adjust it and the end address properly.

2014-09-08arm64: Add CONFIG_DEBUG_SET_MODULE_RONX supportLaura Abbott
In a similar fashion to other architecture, add the infrastructure and Kconfig to enable DEBUG_SET_MODULE_RONX support. When enabled, module ranges will be marked read-only/no-execute as appropriate.
