 * description below), bump the maximum value of _COMM_PAGE_LAYOUT_VERSION.  The kernel should
 * always use the latest version.  Individual build targets may default to lower versions as
 * needed.  For layout versions lower than the version in which an RO variant was added, the
 * field should be defined to use the "legacy" RW offset.  In general, we expect these comm page
 * fields to only be used by platform-level binaries, which are typically coupled to the SDK.
 * A notable exception are simulator targets, which must run the latest platform binaries against
 * older host kernels.  Individual builds can also override _COMM_PAGE_LAYOUT_VERSION if they
 * should need to for some reason.
 * Note that we don't use the _COMM_PAGE_VERSION field to provide conditional runtime access
 * to these RO fields, as the version resides in the legacy kernel-writable page and could be
 * spoofed by an attacker.
