c2aed5122b After discussions with Nate, repo copy the acpi assist drivers from
i386 to dev/acpi_support.  In theory, these devices could be found
other than in i386 machines only as amd64 becomes more popular.  These
drivers don't appear to do anything i386 specific, so move them to
dev/acpi_support.  Move config lines to files so that those
architectures that don't support kernel modules can build them into
the kernel.  At the same time, rename acpi_snc to acpi_sony to follow
the lead of all the other specialty devices.

078080c965 o Change the strcmp() to a strncmp() to allow us to attach to 'E'
models of laptops, which are essentially the same as the normal
   ones, as far as acpi_asus is concerned[1]

 o Use the above as an excuse to reshuffle the mess I made of the
   probe function when I originally wrote it.

d3bdd24ea9 Disable interrupts after using pmap_enter() to add the identity mapping.
Since pmap_enter() calls pmap_invalidate_page(), which needs interrupts
enabled in the SMP case, we defer the disable to right before saving the
register context.  This has been incorrect for about a year but caused no
real problems because the identity page never actually replaces a previously
mapped page and suspend/resume on SMP systems has been uncommon.

0cafadacae Remove the attempt to cache the previous page mapped at our identity
location (for the wake code).  It should not be needed since we don't
map other pages at the same location and if there was an old mapping, it
would be restored by a fault.  The old code had serious problems, namely
that it was restoring the new page it had just removed (not opage) and
it could only guess at the right protection (since there's no
pmap_extract_protect function).  Thanks to Alan Cox for explaining much
of this to me.

Also, remove a commented-out initializecpu() call since it is not needed.
Restoring the cpu context is better than attempting to init from scratch.

3d2e54c317 Push down the acquisition and release of the page queues lock into
pmap_protect() and pmap_remove().  In general, they require the lock in

pmap_protect() can avoid acquiring the lock.

bad4ce7d91 - Use the correct devclass name ("acpi" vs "ACPI") to detect if acpi0 is
present and thus that the PnPBIOS probe should be skipped instead of
  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.

eb8943b13e Rework the APIC mixed mode support a bit:
- Require the APIC enumerators to explicitly enable mixed mode by calling
  ioapic_enable_mixed_mode().  Calling this function tells the apic driver
  that the PC-AT 8259A PICs are present and routable through the first I/O
  APIC via an ExtINT pin.  The mptable enumerator always calls this
  function for now.  The MADT enumerator only enables mixed mode if the
  PC-AT compatability flag is set in the MADT header.
- Allow mixed mode to be enabled or disabled via a 'hw.apic.mixed_mode'
  tunable.  By default this tunable is set to 1 (true).  The kernel option
  NO_MIXED_MODE changes the default to 0 to preserve existing behavior, but
  adding 'hw.apic.mixed_mode=0' to loader.conf achieves the same effect.
- Only use mixed mode to route IRQ 0 if it is both enabled by the APIC
  enumerator and activated by the loader tunable.  Note that both
  conditions must be true, so if the APIC enumerator does not enable mixed
  mode, then you can't set the tunable to try to override the enumerator.

0fd166d7da - Change madt_map_table() to verify the checksum of any table it is asked
to map.  If the checksum fails, the table is unmapped and a NULL pointer
  returned.
- For ACPI version >= 2.0, check the extended checksum of the RSDP.
  AcpiOsGetRootPointer() already checks the version 1.0 checksum.
- Remap the full MADT table at the end of madt_probe() so that we verify
  its checksum before saying it is really there.

635af77a22 Have ACPI use BUS_CONFIG_INTR() to force the SCI to level trigger and
active low polarity when using the PIC interrupt model.  This should fix
broken SCI interrupts on machines when not using the APIC where the BIOS
doesn't program the ELCR to level trigger for the ACPI SCI.

c2ce35977e - Change the APIC code to mostly use the recently added intr_trigger
and intr_polarity enums for passing around interrupt trigger modes and
  polarity rather than using the magic numbers 0 for level/low and 1 for
  edge/high.
- Convert the mptable parsing code to use the new ELCR wrapper code rather
  than reading the ELCR directly.  Also, use the ELCR settings to control
  both the trigger and polarity of EISA IRQs instead of just the trigger
  mode.
- Rework the MADT's handling of the ACPI SCI again:
  - If no override entry for the SCI exists at all, use level/low trigger
    instead of the default edge/high used for ISA IRQs.
  - For the ACPI SCI, use level/low values for conforming trigger and
    polarity rather than the edge/high values we use for all other ISA
    IRQs.
  - Rework the tunables available to override the MADT.  The
    hw.acpi.force_sci_lo tunable is no longer supported.  Instead, there
    are now two tunables that can independently override the trigger mode
    and/or polarity of the SCI.  The hw.acpi.sci.trigger tunable can be
    set to either "edge" or "level", and the hw.acpi.sci.polarity tunable
    can be set to either "high" or "low".  To simulate hw.acpi.force_sci_lo,
    set hw.acpi.sci.trigger to "level" and hw.acpi.sci.polarity to "low".
    If you are having problems with ACPI either causing an interrupt storm
    or not working at all (e.g., the power button doesn't turn invoke a
    shutdown -p now), you can try tweaking these two tunables to find the
    combination that works.

f203f177f4 Revert part of the "BIOS brain damage" from rev 1.10. It seems that
different BIOSs use the same exact settings to mean two very different and
incompatible things for the SCI.  Thus, if the SCI is remapped to a PCI
interrupt, we now trust the trigger/polarity that the MADT provides by
default.  However, the SCI can be forced to level/lo as 1.10 did by setting
the tunable "hw.acpi.force_sci_lo" to a non-zero value from the loader.

Thus, if rev 1.10 caused an interrupt storm, it should nwo fix your
machine.  If rev 1.10 fixed an interrupt storm on your machine, you
probably need to set the aforementioned tunable in /boot/loader.conf to
prevent the interrupt storm.

The more general problem of getting the SCI's trigger/polarity programmed
"correctly" (for some value of correctly meaning several workarounds for
broken BIOSs and inconsistent "implementations" of the ACPI standard) is
going to require more work, but this band-aid should improve the current
situation somewhat.
