something in this batch broke the build on x86 on current -git. Somewhat band-aid-ish fix below.

x86.git testing found the following build error on latest -git:
drivers/acpi/numa.c: In function 'acpi_numa_init': drivers/acpi/numa.c:226: error: 'NR_NODE_MEMBLKS' undeclared (first use in this function) drivers/acpi/numa.c:226: error: (Each undeclared identifier is reported only once drivers/acpi/numa.c:226: error: for each function it appears in.)
with this config:
http://redhat.com/~mingo/misc/config-Wed_Apr_30_22_42_42_CEST_2008.bad
i suspect we dont want SRAT parsing when CONFIG_HAVE_ARCH_PARSE_SRAT is unset - but the fix looks a bit ugly. Perhaps we should define NR_NODE_MEMBLKS even in this case and just let the code fall back to some sane behavior?
