Xen for noHV now uses an OF tree node to tell Linux it is running in a problem-state partition, rather than the kluge of an MSR bit for this purpose.
As usual, patches for Xen and Linux are available for interested parties. For those with access to my source tree /a/kix/homes/kix/mergen/xen, the Xen patch is in xen-nohv/xen-nohv and the Linux patch is in linux/linux-2.6.prlp/linux-prlp. You also need the two new Xen files arch/powerpc/powerpc64/nohv.c and include/asm-powerpc/nohv.h. These mods work against Xen and Linux trees from xensource at the time of this note.
