optional attributes field.
- Add a 'machdep.smap' sysctl that exports the SMAP table of the running
system as an array of the ACPI 3.0 structure. (On older systems, the
attributes are given a value of zero.) Note that the sysctl only
exports the SMAP table if it is available via the metadata passed from
the loader to the kernel. If an SMAP is not available, an empty array
is returned.
- Add a format handler for the ACPI 3.0 SMAP structure to the sysctl(8)
binary to format the SMAP structures in a readable format similar to
the format found in boot messages.

e820 memory map is fetched using a hypercall under Xen PVH, so add a

x86/include/init.h:
- Add a parse_memmap hook to init_ops, that will be called to fetch
and parse the memory map.
amd64/amd64/machdep.c:
- Decouple the fetch and the parse of the memmap, so the parse
function can be shared with Xen code.
- Move code around in order to implement the parse_memmap hook.
amd64/include/pc/bios.h:
- Declare bios_add_smap_entries (implemented in machdep.c).
x86/xen/pv.c:
- Implement fetching of e820 memmap when running as a PVH guest by
using the XENMEM_memory_map hypercall.

defined by standards ($PIR table, SMAP entries, etc.) available to
userland.
- Consolidate duplicate SMBIOS table structure definitions in ipmi(4)
and smbios(4) in <machine/pc/bios.h> and make them available to
userland.

- Do not iterate int 15h, function e820h twice. Instead, we use STAILQ to
store each return buffer and copy all at once.
- Export optional extended attributes defined in ACPI 3.0 as separate
metadata. Currently, there are only two bits defined in the specification.
For example, if the descriptor has extended attributes and it is not
enabled, it has to be ignored by OS. We may implement it in the kernel
later if it is necessary and proven correct in reality.
- Check return buffer size strictly as suggested in ACPI 3.0.

This fixes recognition of the PC Engines WRAP and improves the
recognition of the Soekris boards (Bios version can now be
seen in the dmesg output for instance).
Also, add watchdog support for PCM-582x platforms.

having ACPI zero out the PnPBIOStable pointer.
- Make the PnPBIOStable pointer static to i386/i386/bios.c now that that is
the only place it is used.
and such was just a bad idea and one that users should be forced to
enable if they want it. This patch introduces a hw.pci.enable_pcibios

- Move all register I/O into acpi_io.c
- Move event handling into acpi_event.c
- Reorganise headers into acpivar/acpireg/acpiio
- Move find-RSDT and find-ACPI-owned-memory into acpi_machdep
- Allocate all resources (except those detailed only by AML)
as real resources. Add infrastructure that will make adding
resource support to AML code easy.
- Remove all ACPI #ifdefs in non-ACPI code
- Removed unnecessary includes
- Minor style and commenting fixes

- Add support for using the PCI BIOS functions for configuration space
accesses, and make this the default.
- Make PNPBIOS the default (obsoletes the PNPBIOS config option).
- Add two new boot-time tunables to disable each of the above.
- Add support for calling 32-bit code in other segments
- Add support for calling 16-bit protected mode code
Update APM to use this facility.
