that turned out to be unrelated, and the rest was, as pointed out by Neel,
just wrong-headed.
o) Tweak mem.c to fix use of /dev/kmem for direct-mapped addresses.
this in the Sibyte PCI hostbridge driver instead.
The nexus driver sees resource allocation requests for memory and irq
resources only. These are legitimate resources on all MIPS platforms.

the 'debugging' section of any HEAD kernel and enable for the mainstream
ones, excluding the embedded architectures.
It may, of course, enabled on a case-by-case basis.

The platform that supports SMP currently is a SWARM with a dual-core Sibyte
processor. The kernel config file to use is SWARM_SMP.

locks up in make buildworld.
You need to follow the mips wiki for building
the nfs partition and setup things to mount there
(in the conf and in your bootp setup).
I think these are the relevant changes, but definitely are a superset
of them. Software archaeologists are invited to check the branch
itself for the details.

The default KERNLOADADDR does not work on MALTA hardware. On my platform the
"First free SDRAM address" reported by YAMON is 0x800b6e61.
So use a conservative KERNLOADADDR of 0x80100000.

- Replace CPU_NOFPU and SOFTFLOAT options with CPU_FPU. By default
we assume that there is no FPU, because majority of SoC does
not have it.

hit a panic after :
uart0: <16550 or compatible> on iodi0
Trap cause = 2 (TLB miss....)
I did have to take the pci bus OUT of the
build to get this far, hit a cache error with
the PCI code in. Interesting thing is the machine
reboots too ;-)
