64bb257f0b Always install IDT entries for ATPIC interrupt sources. The APIC no
longer uses these interrupt vectors for its ISA interrupt pins, so these
entries will not be overwritten.  If we get a spurious interrupt from the
ATPIC when using the APIC, it will be treated as a stray interrupt instead
of causing a panic.

43d63d12fa If an interrupt source doesn't have an ithread, treat it as a stray
interrupt.  This can only happen if an unregistered interrupt source
triggers an interrupt.

be06bd496f - Bring in constants for 8259A registers from amd64 with some updated
comments from NetBSD's dev/ic/i8259A.h.  These bits really belong in
  a file of the same name as well, but this will do for now.
- Axe unused HWI_MASK.

3ab2ba59f4 Shuffle the APIC interrupt vectors around a bit:
- Move the IPI and local APIC interrupt vectors up into the 0xf0 - 0xff
  range.  The pmap lazyfix IPI was reordered down next to the TLB
  shootdowns to avoid conflicting with the spurious interrupt vector.
- Move the base of APIC interrupts up 16 so that the first 16 APIC
  interrupts do not overlap the vectors used by the ATPIC.
- Remove bogus interrupt vector reservations for LINT[01].
- Now that 0xc0 - 0xef are available, use them for device interrupts.
  This increases the number of APIC device interrupts to 191.
- Increase the system-wide number of global interrupts to 191 to catch up
  to more APIC interrupts.

bd9cd7e3f7 - Move manipulation of td_intr_nesting_level out of assembly interrupt
vector stubs and into the C functions they call.
- Move disabling and EOIing of interrupt sources out of PIC driver entry
  points and into intr_execute_handlers().  Intr_execute_handlers() only
  disables a source for an interrupt if it is a stray interrupt or has
  threaded handlers.  Sources with fast handlers no longer disable (mask)
  the source while executing the handlers.
- Move the setting of clkintr_pending into intr_execute_handlers() and set
  the variable for any interrupt source with a vector of 0.  (Should only
  be true for IRQ 0.)  This fixes clkintr_pending in the NO_MIXED_MODE
  case.
- Implement lapic_eoi() and use it to implement ioapic_eoi_source().
- Rename atpic_sched_ithd() to atpic_handle_intr() since it is used to
  handle all atpic interrupts and not just threaded ones.

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.

da17811e64 Enable HTT CPUs by default instead of halting them by default. Users
should now only have HTT CPUs if they have explicitly asked for them

f9dbba5c4e Disable probing of HTT CPUs by default for the MP Table case. HTT CPUs
should only be used if they are enabled in the BIOS.  Now that we support
enumerating CPUs using the ACPI MADT, any HTT machine using ACPI should
respect the BIOS setting.  For HTT machines with ACPI disabled in the
kernel, the MPTABLE_FORCE_HTT kernel option can be used to try to probe HTT
CPUs like have done in the past for the MP Table case.  This option should
only be enabled if HTT is enabled in the BIOS.

fcaa2925a9 Change the clear_ret argument of get_mcontext() to be a flags argument.
Since all callers either passed 0 or 1 for clear_ret, define bit 0 in
the flags for use as clear_ret. Reserve bits 1, 2 and 3 for use by MI
code for possible (but unlikely) future use. The remaining bits are for
use by MD code.

This change is triggered by a need on ia64 to have another knob for
get_mcontext().

512824f8f7 - Implement selwakeuppri() which allows raising the priority of a
thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.

5e4a2fc9aa - Similar to post-PAE RELENG_4 split pmap_pte_quick() into two cases,
pmap_pte() and pmap_pte_quick().  The distinction being based upon the
   locks that are held by the caller.  When the given pmap is not the
   current pmap, pmap_pte() should be used when Giant is held and
   pmap_pte_quick() should be used when the vm page queues lock is held.
 - When assigning to PMAP1 or PMAP2, include PG_A anf PG_M.
 - Reenable the inlining of pmap_is_current().

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.
