 * Notes:
 * InfiniteReality (Kona) graphics boards in Onyx2 systems are not currently supported. Patches welcome!
 * Support is in mainline & linux-mips kernels, but appears to be very flakey, especially with the current in-tree IOC3 driver. Use  and the IOC3 metadriver for more stable operation of these systems until the metadriver code is accepted upstream.
 * CONFIG_TRANSPARENT_HUGEPAGE does not work reliably on this platform. Random SIGSEGV or SIGBUS events will happen.  Do not use it unless you are trying to debug the problem.  Possibly an issue with the current MIPS TLB code.
 * There is a yet-to-be determined bug in current kernels that causes IP27-class hardware to lock up after a period of time. The lock up can be triggered sooner by performing heavy disk I/O (such as a bonnie++ run).  A possible cause may be a VM_BUG_ON_PAGE in mm/page_alloc.c:1490, in move_freepages.  Why or how this BUG variant is getting triggered is currently unknown.
