3ac98abb89 Revert the logic change from r269540. If the opt_inet6.h file is empty
we set MK_INET6_SUPPORT to no, not if we do define INET6.
This way we do not try to build IPv6 parts in if the kernel doesn't support
them.

This unbreaks several kernel configurations building modules but no INET6.

b86acea372 vm_phys: improve robustness of fictitious ranges
With the current implementation of managed fictitious ranges when
also using VM_PHYSSEG_DENSE, a user could try to register a
fictitious range that starts inside of vm_page_array, but then
overrruns it (because the end of the fictitious range is greater than
vm_page_array_size + first_page). This would result in PHYS_TO_VM_PAGE
returning unallocated pages from past the end of vm_page_array. The
same could happen if a user tried to register a segment that starts
outside of vm_page_array but ends inside of it.

In order to fix this, allow vm_phys_fictitious_{reg/unreg}_range to
use a set of pages from vm_page_array, and allocate the rest.

991a1f338d Merge all MD sf_buf allocators into one MI, residing in kern/subr_sfbuf.c
The MD allocators were very common, however there were some minor
differencies. These differencies were all consolidated in the MI allocator,
under ifdefs. The defines from machine/vmparam.h turn on features required
for a particular machine. For details look in the comment in sys/sf_buf.h.

As result no MD code left in sys/*/*/vm_machdep.c. Some arches still have
machine/sf_buf.h, which is usually quite small.

Lower the quality of the MADT ACPI enumerator, so on Xen Dom0 we can

This is needed because Xen might restrict the number of vCPUs

native one (which enumerates all the CPUs available in the system).

1bfb01ea6b xen: change order of Xen intr init and IO APIC registration
This change inserts the Xen interrupt subsystem (event channels)
initialization between the system interrupt initialization and the IO
APIC source registration.

This is needed when running on Dom0, that routes physical interrupts
on top of event channels, so that the interrupt sources found during
IO APIC initialization can be registered using the Xen interrupt
subsystem.

The resulting order in the SI_SUB_INTR stage is the following:

- System intr initialization
- Xen intr initalization
- IO APIC source registration
