Now I've got it working. I believe this is a bug in Xen introduced very
recently. With this additional _hack_ attached, I was able to restore x86-64
XenLinux with latest bk, and now ACPI works with x86-64 Linux (see below). Keir
should fix the bug properly.
Basically what's happening is that x86-64 xenlinux cannot access
machine-to-phys mapping, which is critical info to the guest.
config.h:
/* Slot 256: read-only guest-accessible machine-to-phys translation table. */
#define RO_MPT_VIRT_START (PML4_ADDR(256))
#define RO_MPT_VIRT_END (RO_MPT_VIRT_START + PML4_ENTRY_BYTES/2)
At this point, as you see, L3 does not have USER bit, and x86-64 XenLinux
cannot access it; it used to be able to do that until recently. My hack just
adds USER bit upon #PF to L3 (see the patch attaced).
