ACPI, ia64: Use SRAT table rev to use 8bit or 16/32bit PXM fields (ia64)
In SRAT v1, we had 8bit proximity domain (PXM) fields; SRAT v2 provides 32bits for these. The new fields were reserved before. According to the ACPI spec, the OS must disregrard reserved fields. ia64 did handle the PXM fields almost consistently, but depending on sgi's sn2 platform. This patch leaves the sn2 logic in, but does also use 16/32 bits for PXM if the SRAT has rev 2 or higher. The patch also adds __init to the two pxm accessor functions, as they access __initdata now and are called from an __init function only anyway. Note that the code only uses 16 bits for the PXM field in the processor proximity field; the patch does not address this as 16 bits are more than enough.
