* Reserved Page provided by SAL.
* the reserved page
*
* SAL reserves one page of memory per partition for XPC. Though a full page
* in length (16384 bytes), its starting address is not page aligned, but it
* is cacheline aligned. The reserved page consists of the following:
*
* reserved page header
*
* The first cacheline of the reserved page contains the header
* (struct xpc_rsvd_page). Before SAL initialization has completed,
* SAL has set up the following fields of the reserved page header:
* SAL_signature, SAL_version, partid, and nasids_size. The other
* fields are set up by XPC. (xpc_rsvd_page points to the local
* partition's reserved page.)
*
* SAL provides one page per partition of reserved memory. When SAL
* initialization is complete, SAL_signature, SAL_version, partid,
* part_nasids, and mach_nasids are set.
* part_nasids mask
* mach_nasids mask
*
* SAL also sets up two bitmaps (or masks), one that reflects the actual
* nasids in this partition (part_nasids), and the other that reflects
* the actual nasids in the entire machine (mach_nasids). We're only
* interested in the even numbered nasids (which contain the processors
* and/or memory), so we only need half as many bits to represent the
* nasids. The part_nasids mask is located starting at the first cacheline
* following the reserved page header. The mach_nasids mask follows right
* after the part_nasids mask. The size in bytes of each mask is reflected
* by the reserved page header field 'nasids_size'. (Local partition's
* mask pointers are xpc_part_nasids and xpc_mach_nasids.)
*
* vars
* vars part
*
* Immediately following the mach_nasids mask are the XPC variables
* required by other partitions. First are those that are generic to all
* partitions (vars), followed on the next available cacheline by those
* which are partition specific (vars part). These are setup by XPC.
* (Local partition's vars pointers are xpc_vars and xpc_vars_part.)
*
* Note: Until vars_pa is set, the partition XPC code has not been initialized.
