030b156bf0 Add a simple mini-driver for the ELCR register. Originally, the ELCR
register controlled the trigger mode and polarity of EISA interrupts.
However, it appears that most (all?) PCI systems use the ELCR to manage
the trigger mode and polarity of ISA interrupts as well since ISA IRQs used
to route PCI interrupts need to be level triggered with active low
polarity.  We check to see if the ELCR exists by sanity checking the value
we get back ensuring that IRQS 0 (8254), 1 (atkbd), 2 (the link from the
slave PIC), and 8 (RTC) are all clear indicating edge trigger and active
high polarity.

This mini-driver will be used by the atpic driver to manage the trigger and
polarity of ISA IRQs.  Also, the mptable parsing code will use this mini
driver rather than examining the ELCR directly.

b14d6acced - pmap_kenter_temporary() is unused by machine-independent code. Therefore,
move its declaration to the machine-dependent header file on those
   machines that use it.  In principle, only i386 should have it.
   Alpha and AMD64 should use their direct virtual-to-physical mapping.
 - Remove pmap_kenter_temporary() from ia64.  It is unused.  Approved

a36bdc0606 Introduce the cpumask_t type. The purpose of the type is to create a
level of abstraction for any and all CPU mask and CPU bitmap variables
so that platforms have the ability to break free from the hard limit
of 32 CPUs, simply because we don't have more bits in an u_int. Note
that the type is not supposed to solve massive parallelism, where
the number of CPUs can be larger than the width of the widest integral
type. As such, cpumask_t is not supposed to be a compound type. If
such would be necessary in the future, we can deal with the issues
then and there. For now, it can be assumed that the type is integral
and unsigned.

With this commit, all MD definitions start off as u_int. This allows
us to phase-in cpumask_t at our leasure without breaking anything.
Once cpumask_t is used consistently, platforms can switch to wider
(or smaller) types if such would be beneficial (or not; whatever :-)

a122cca953 These are changes to allow to use the Intel C/C++ compiler (lang/icc)

Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as
icc v8 may define __GNUC__ some parts may look strange but are
necessary.

Additional changes:

     The entire checksum code should IMHO be replaced with the DragonFly
     version (because it isn't guaranteed future revisions of gcc will
     include similar optimizations) as in:

Incarnations of this patch survive gcc compiles since a loooong time,
I use it on my desktop. An icc compiled kernel works since Nov. 2003
(exceptions: snd_* if used as modules), it survives a build of the
entire ports collection with icc.

a67ef0a77a Don't implement anything in the ffs family in <machine/cpufunc.h>
in the non-_KERNEL case.  This "fixes" applications that include
this "kernel-only" header and also include <strings.h> (or get
<strings.h> via the default _BSD_VISIBLE pollution in <string.h>.
In C++ there was a fatal error: the declaration specifies C linkage
but the implementation gives C++ linkage.  In C there was only a
static/extern mismatch if the headers were included in a certain order
order, and a partially redundant declaration for all include orders;
gcc emits incomplete or wrong diagnostics for these, but only for
compiling with -Wsystem-headers and certain other warning options, so
the problem was usually not seen for C.

4168deefd6 Add new CPU_ENABLE_TCC option, from NOTES:
CPU_ENABLE_TCC enables Thermal Control Circuitry (TCC) found in some
Pentium(tm) 4 and (possibly) later CPUs. When enabled and detected,
TCC allows to restrict power consumption by using machdep.cpuperf*
sysctls. This operates independently of SpeedStep and is useful on
systems where other mechanisms such as apm(4) or acpi(4) don't work.

Given the fact that many, even modern, notebooks don't work properly
with Intel ACPI, this is indeed very useful option for notebook owners.

a5819cb5b5 Don't remove the virtual-to-physical mapping when an sf_buf is freed.
Instead, allow the mapping to persist, but add the sf_buf to a free list.
If a later sendfile(2) or zero-copy send resends the same physical page,
perhaps with the same or different contents, then the mapping overhead is
avoided and the sf_buf is simply removed from the free list.

In other words, the i386 sf_buf implementation now behaves as a cache of
virtual-to-physical translations using an LRU replacement policy on
inactive sf_bufs.  This is similar in concept to a part of
http://www.cs.princeton.edu/~yruan/debox/ patch, but much simpler in
implementation.  Note: none of this is required on alpha, amd64, or ia64.
They now use their direct virtual-to-physical mapping to avoid any
emphemeral mapping overheads in their sf_buf implementations.

88afb90f3c Updated cx driver commit part 1: bring in the new kernel driver.
This is the vastly updated cx drvier from Roman Kurakin <rik@cronyx.ru>
who has been patiently waiting for this update for sometime.

The driver is mostly a rewrite from the version we have in the tree.
While some similarities remain, losing the little history that the old
driver has is not a big loss, and the re@ felt it was easier this way (less
error prone).

The userland parts of this update will be committed shortly.

The driver is not connected to the build yet.  I want to make sure I
don't break any platform at any time, so I want to test that with
these files in the tree before I continue (on the off chance I'm
forgetting a file).

I changed the DEBUG macro to CX_DEBUG from the code that was submitted
(to not break when we go to building with opt_global.h after the
release), as well adding $FreeBSD$.

0543fa5398 - Change the i386's sf_buf implementation so that it never allocates
more than one sf_buf for one vm_page.  To accomplish this, we add
   a global hash table mapping vm_pages to sf_bufs and a reference
   count to each sf_buf.  (This is similar to the patches for RELENG_4
   at http://www.cs.princeton.edu/~yruan/debox/.)

   For the uninitiated, an sf_buf is nothing more than a kernel virtual
   address that is used for temporary virtual-to-physical mappings by
   sendfile(2) and zero-copy sockets.  As such, there is no reason for
   one vm_page to have several sf_bufs mapping it.  In fact, using more
   than one sf_buf for a single vm_page increases the likelihood that
   sendfile(2) blocks, hurting throughput.

- 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.
