8283c726e7 If the XSDT address in the RSDP for an ACPI 2.0 machine is NULL, then fall
back to using the RSDT instead.  ACPI-CA already follows this same strategy
as a workaround for yet another instance of brain-damaged BIOS writers.

5bb84bc84b Normalize a significant number of kernel malloc type names:
- Prefer '_' to ' ', as it results in more easily parsed results in
  memory monitoring tools such as vmstat.

- Remove punctuation that is incompatible with using memory type names
  as file names, such as '/' characters.

- Disambiguate some collisions by adding subsystem prefixes to some
  memory types.

- Generally prefer lower case to upper case.

- If the same type is defined in multiple architecture directories,
  attempt to use the same name in additional cases.

Not all instances were caught in this change, so more work is required to
finish this conversion.  Similar changes are required for UMA zone names.

ba5f6b61da MFi386: use the lapic timer for UP systems that are using the apic so that
IRQ0 and mixed mode isn't a problem anymore.  This removes mixed mode

373dd87688 - Add a new quirk to indicate that pin 0 of the first I/O APIC is really
IRQ 0 and not an ExtINT pin.  The MADT enumerators ignore the PC-AT flag
  and ignore overrides that map IRQ 0 to pin 2 when this quirk is present.
- Add a block comment above the quirks to document each quirk so that we
  can use more verbose descriptions quirks.

d3c01334ce Some motherboards like to remap the SCI (normally IRQ 9) up to a PCI
interrupt such as IRQ 22 or 19.  However, the ACPI BIOS still routes
interrupts from some PCI devices to the same intpin calling the pin
IRQ 22.  Thus, ACPI expects to address a single interrupt source via two
different names.  To work around this, if the SCI is remapped to a non-ISA
interrupt (i.e., greater than 15), then we use
acpi_OverrideInterruptLevel() function to tell ACPI to use IRQ 22 or 19
rather than IRQ 9 for the SCI.

Previously we would change IRQ 22 or 19's name to IRQ 9 when we encountered
such an Interrupt Source Override entry in the MADT which routed the SCI
properly but left PCI devices mapped to IRQ 22 or 19 w/o a routable
interrupt.

f84d8b318a When remapping an ISA interrupt from one intpin to another, disable the
pin that is used by the default identity mapping if it still maps to the
old vector.  The ACPI case might need some tweaking for the SCI interrupt
case since ACPI likes to address the intpin using both the IRQ remapped to
it as well as the previous existing PCI IRQ mapped to it.

ab089945d3 Add the ACPI MADT table APIC enumerator. This code uses the ACPI Multiple
APIC Descriptor Table to enumerate both I/O APICs and local APICs.  ACPI
does not embed PCI interrupt routing information in the MADT like the MP
Table does.  Instead, ACPI stores the PCI interrupt routing information
in the _PRT object under each PCI bus device.  The MADT table simply
provides hints about which interrupt vectors map to which I/O APICs.  Thus
when using ACPI, the existing ACPI PCI bridge drivers are sufficient to
route PCI interrupts.

afa8862328 Commit MD parts of a loosely functional AMD64 port. This is based on
a heavily stripped down FreeBSD/i386 (brutally stripped down actually) to
attempt to get a stable base to start from.  There is a lot missing still.
Worth noting:
- The kernel runs at 1GB in order to cheat with the pmap code.  pmap uses
  a variation of the PAE code in order to avoid having to worry about 4
  levels of page tables yet.
- It boots in 64 bit "long mode" with a tiny trampoline embedded in the
  i386 loader.  This simplifies locore.s greatly.
- There are still quite a few fragments of i386-specific code that have
  not been translated yet, and some that I cheated and wrote dumb C
  versions of (bcopy etc).
- It has both int 0x80 for syscalls (but using registers for argument
  passing, as is native on the amd64 ABI), and the 'syscall' instruction
  for syscalls.  int 0x80 preserves all registers, 'syscall' does not.
- I have tried to minimize looking at the NetBSD code, except in a couple
  of places (eg: to find which register they use to replace the trashed
  %rcx register in the syscall instruction).  As a result, there is not a
  lot of similarity.  I did look at NetBSD a few times while debugging to
  get some ideas about what I might have done wrong in my first attempt.

227f9a1c58 - Add vm_paddr_t, a physical address type. This is required for systems
where physical addresses larger than virtual addresses, such as i386s
  with PAE.
- Use this to represent physical addresses in the MI vm system and in the
  i386 pmap code.  This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
  detection code, and due to kvtop returning vm_paddr_t instead of u_long.

Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

Initialize struct cdevsw using C99 sparse initializtion and remove

LINT with all the fields in struct cdevsw in reverse order on alpha,

91c71b46ed Export the physical address of the RSDP to userland by means
of the `machdep.acpi_root' sysctl. This is required on ia64
because the root pointer hardly ever, if at all, lives in the
first MB of memory and also because scanning the first MB of
memory can cause machine checks.
This provides a save and reliable way for ACPI tools to work
with the tables if ACPI support is present in the kernel. On
ia64 ACPI is non-optional.

ebff7660a3 *sigh*. It seems that in the ACPICA code, Intel defines its own APIC_IO
macro for use when parsing MADT tables, thus we always tried to set the
interrupt model to APIC.  This proved to be harmful on UP machines with
IO APIC's (or for UP kernels on SMP machines) since the wrong interrupt
routing information would be returned.
