sh and sh64 need xlate_dev_mem_ptr/xlate_dev_kmem_ptr definitions too..
otherwise end up with:

- Make sure that io-apic is enabled, boot with `nmi_watchdog=1'.

- Make sure that CONFIG_DETECT_SOFTLOCKUP is enabled

- Add `initcall_debug' to the boot command line, see if that tells us
anything.

- Disable CONFIG_DEBUG_PAGEALLOC, if it was enabled

- Send me your .config.

kgdb is the way to diagnose this one.

Yeah, this is going to take a while. I've ordered an usb-to-serial converter
for my laptop so that I can connect it to the desktop machine over the serial
port and this is gonna be here next week so then I'll give kgdb a try.
