Does HIGHMEM work on 32-bit MIPS ports?

[David VomLehn <dvomlehn@xxxxxxxxx>]

As we continue to investigate using high memory on MIPS, we keep coming 
up with odd results. The basic mapping of high memory seems to be 
working correctly, and if we use an INITRAMFS root filesystem, things 
seem to work. Things also seem to work with an NFS root filesystem if we 
disable preemption, though we get someone squirrelly behavior in some 
minor ways. Has anyone else successfully been able to use high memory on 
a 32-bit MIPS Linux port?

Any feedback would be helpful.
