[Xen-devel] ACPI fixmap overflow

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

In addition to running out of e820 entries on that large machine that
Alex was referring to in [0] he is also running out of ACPI fixmap space
while parsing MADT (the box has *lots* of processors). The
quick-and-dirty solution is to increase NUM_FIXMAP_ACPI_PAGES but I
wonder whether we should move to dynamic memory allocation.
