Catalin Marinas a501e32430 arm64: Clean up the default pgprot setting ... The primary aim of this patchset is to remove the pgprot_default and prot_sect_default global variables and rely strictly on predefined values. The original goal was to be able to run SMP kernels on UP hardware by not setting the Shareability bit. However, it is unlikely to see UP ARMv8 hardware and even if we do, the Shareability bit is no longer assumed to disable cacheable accesses. A side effect is that the device mappings now have the Shareability attribute set. The hardware, however, should ignore it since Device accesses are always Outer Shareable. Following the removal of the two global variables, there is some PROT_* macro reshuffling and cleanup, including the __PAGE_* macros (replaced by PAGE_*).
