same time. o) Remove some unused trivial uart functions from octeon_machdep now that the uart part is fully working and they are unused. o) Use __func__ instead of __FUNCTION__. o) Use intr_*() instead of other routines that do the same thing. o) Remove some duplicate printfs from the Octeon port, as well as duplicate setting of Maxmem. o) Use the right frequency divider on Octeon. o) Use PCPU_GET(cpuid) consistently to get the cpuid of the running core. o) Remove some unused macros in the Octeon port. o) Use mips_sync() around use of the global dpcpu, whose value may not be visible to APs at first. o) When loading the first thread's stack, use macros to make the code correct for n64 as well. o) Remove stub, do-nothing FAU init/enable/disable functions from the RGMX driver.
