There's no reason that cpu_do_switch_mm() needs to be written as an assembly function, and having it as a C function would make it easier to maintain. This patch converts cpu_do_switch_mm() to C, removing code that this change makes redundant (e.g. the mmid macro). Since the header comment was stale and the prototype now implies all the necessary information, this comment is removed. The 'pgd_phys' argument is made a phys_addr_t to match the return type of virt_to_phys(). At the same time, post_ttbr_update_workaround() is updated to use IS_ENABLED(), which allows the compiler to figure out it can elide calls for !CONFIG_CAVIUM_ERRATUM_27456 builds. There should be no functional change as a result of this patch.
