I'm not sure what's in Andi's tree. He mentioned that he had trouble merging a previous patch I had, but it wasn't a particularly big change.

Andi, where can I get your tree?

Anyway, the PDA patches are causing my little old dual-pIII to reboot about
one second into the boot process.

Interesting. Have there been any other complaints about -mm crashing? There's nothing in here which is "new cpu"; it should work the same all the way back to an i386.

Bisection says:

x86_64-mm-i386-pda-asm-offsets.patch
x86_64-mm-i386-pda-basics.patch                         OK
x86_64-mm-i386-pda-init-pda.patch                       oops
x86_64-mm-i386-pda-use-gs.patch				reboot
x86_64-mm-i386-pda-user-abi.patch                       BAD
x86_64-mm-i386-pda-vm86.patch
x86_64-mm-i386-pda-smp-processorid.patch
x86_64-mm-i386-pda-current.patch


So x86_64-mm-i386-pda-init-pda.patch causes the below oops and
x86_64-mm-i386-pda-use-gs.patch causes the instareboot.
