I'm not aware of a current or planned HP machine where ptc.g will
not work.

Sometimes ptc.g doesn't work because of defects in early processor
or chipset prototypes, but I consider that a bring-up issue that is
not significant enough to warrant additional permanent code in the
kernel.

So I don't think we should have a special machvec for HP machines.
