Completely remove the remaining EFI includes and add our own (type)
definitions instead. While here, abstract more of the internals by
providing interface functions.

1a26ea7f2c Add machdep quirks functions. On i386, this disables acpi on systems with
BIOS dates earlier than Jan 1, 1999.  Add prototypes and quirks flags.

5e3cb29a6b Untangle the code in this file to improve understandability. Both
ia64_count_cpus() and ia64_probe_sapics() called a single function
to do the the actual work. The difference in behaviour was handled
in that function and was further complicated by adding bootverbose
related code. As such, even the simplest of changes was hard to
comprehend.

Untangling has been done by increasing code duplication and using
a more naive style of coding. FWIW, the object file is slightly
smaller than before, so things aren't as bad as it may seem.

Triggered by: a simple fix on the P4 branch that never got merged.

26502503e5 Further cleanup <machine/cpu.h> and <machine/md_var.h>: move the MI
prototypes of cpu_halt(), cpu_reset() and swi_vm() from md_var.h to
cpu.h. This affects db_command.c and kern_shutdown.c.

ia64: move all MD prototypes from cpu.h to md_var.h. This affects
madt.c, interrupt.c and mp_machdep.c. Remove is_physical_memory().
It's not used (vm_machdep.c).

alpha: the MD prototypes have been left in cpu.h with a comment
that they should be there. Moving them is left for later. It was
expected that the impact would be significant enough to be done in
a seperate commit.

powerpc: MD prototypes left in cpu.h. Comment added.

c58d580e70 Don't hardcode the address of the local (S)APIC (aka processor
interrupt block). We use the previously hardcoded address as a
default only, but will otherwise use whatever ACPI tells us.
The address can be found in the MADT table header or in the
LAPIC override table entry.

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.

23c12a63cf o Remove namespace pollution from param.h:
-  Don't include ia64_cpu.h and cpu.h
   -  Guard definitions by  _NO_NAMESPACE_POLLUTION
   -  Move definition of KERNBASE to vmparam.h

o  Move definitions of IA64_RR_{BASE|MASK} to vmparam.h
o  Move definitions of IA64_PHYS_TO_RR{6|7} to vmparam.h

o  While here, remove some left-over Alpha references.

f5b454cf25 o Rename ia64_count_aps to ia64_count_cpus and reimplement the
function to return the total number of CPUs and not the highest
   CPU id.
o  Define mp_maxid based on the minimum of the actual number of
   CPUs in the system and MAXCPU.
o  In cpu_mp_add, when the CPU id of the CPU we're trying to add
   is larger than mp_maxid, don't add the CPU. Formerly this was
   based on MAXCPU. Don't count CPUs when we add them. We already
   know how many CPUs exist.
o  Replace MAXCPU with mp_maxid when used in loops that iterate
   over the id space. This avoids a couple of useless iterations.
o  In cpu_mp_unleash, use the number of CPUs to determine if we
   need to launch the CPUs.
o  Remove mp_hardware as it's not used anymore.
o  Move the IPI vector array from mp_machdep.c to sal.c. We use
   the array as a centralized place to collect vector assignments.
   Note that we still assign vectors to SMP specific IPIs in
   non-SMP configurations. Rename the array from mp_ipi_vector to
   ipi_vector.
o  Add IPI_MCA_RENDEZ and IPI_MCA_CMCV. These are used by MCA.
   Note that IPI_MCA_CMCV is not SMP specific.
o  Initialize the ipi_vector array so that we place the IPIs in
   sensible priority classes. The classes are relative to where
   the AP wake-up vector is located to guarantee that it's the
   highest priority (external) interrupt. Class assignment is
   as follows:
	class	IPI		notes
	x	AP wake-up	(normally x=15)
	x-1	MCA rendezvous
	x-2	AST, Rendezvous, stop
	x-3	CMCV, test

fa45345e6e * Remove a breakpoint() I accidentally left in for debugging :-(.
* Make cpu_mp_probe() work before the VM system is available and
  initialise mp_maxid accordingly.

cd85e2620d Small correction in the LOCAL_SAPIC structure. The Flags field
starts at offset 8; not 6. Hence the structure is 12 bytes and
not 10 bytes. Adjust the definition so that the ProcessorEnabled
flag is moved from bit 15 to bit 31 in the Flags field.

The definition now matches ACPI 2.0 Errata 1.5.

229778f87e o Do not parse the MADT as a side-effect in AcpiOsGetRootPointer,
do it as a side-effect of probing for MP hardware. This allows
   us to scan for local SAPICs early (especially before MBUF
   initialization).
o  Fix the Local SAPIC structure so that matches the Local SAPIC
   table entry. Now that the Local SAPIC info is the same as the
   Local APIC info, stop dumping the Local APIC entries.
o  For every Local SAPIC entry in the MADT that's not disabled,
   let the SMP code know about it. They represent actual CPUs.
o  Register the OS_BOOT_RENDEZ entry point and provide a (bogus)
   implementation for the entry point.
o  Provide a mapping for internal IPI numbers to ExtINT vectors.
o  In a MP system, announce the CPUs and start them by sending
   IPI_AP_WAKEUP to each of them. Not that it makes a difference
   at this time :-)
o  Miscellaneous style fixes and other adjustments.

f86214b6b8 Add APM compatibility feature to ACPI.
This emulates APM device node interface APIs (mainly ioctl) and
provides APM services for the applications.  The goal is to support
most of APM applications without any changes.
Implemented ioctls in this commit are:
 - APMIO_SUSPEND (mapped ACPI S3 as default but changable by sysctl)
 - APMIO_STANDBY (mapped ACPI S1 as default but changable by sysctl)
 - APMIO_GETINFO and APMIO_GETINFO_OLD
 - APMIO_GETPWSTATUS

With above, many APM applications which get batteries, ac-line
info. and transition the system into suspend/standby mode (such as
wmapm, xbatt) should work with ACPI enabled kernel (if ACPI works well :-)

right yet but its enough for the ATA probe to work. The SCSI probes which
