Mark Johnston e76aab6ae2 Call acpi_pxm_set_proximity_info() slightly earlier on x86.
This function is responsible for setting pc_domain in each pcpu
structure.  Call it from the main function that starts APs, rather than
a separate SYSINIT.  This makes it easier to close the window where
UMA's per-CPU slab allocator may be called while pc_domain is
uninitialized.  In particular, the allocator uses pc_domain to allocate
domain-local pages, so allocations before this point end up using domain
0 for everything.
