Arjan van de Ven 488fd99588 x86: fix pageattr-selftest ... In Ingo's testing, he found a bug in the CPA selftest code. What would happen is that the test would call change_page_attr_addr on a range of memory, part of which was read only, part of which was writable. The only thing the test wanted to change was the global bit... What actually happened was that the selftest would take the permissions of the first page, and then the change_page_attr_addr call would then set the permissions of the entire range to this first page. In the rodata section case, this resulted in pages after the .rodata becoming read only... which made the kernel rather unhappy in many interesting ways. This is just another example of how dangerous the cpa API is (was); this patch changes the test to use the incremental clear/set APIs instead, and it changes the clear/set implementation to work on a 1 page at a time basis.
