b8aa843c63 Update to DRM CVS as of 2005-04-12, bringing many changes:
- Split core DRM routines back into their own module, rather than using the
  nasty templated system like before.
- Development-class R300 support in radeon driver (requires userland pieces, of
  course).
- Mach64 driver (haven't tested in a while -- my mach64s no longer fit in the
  testbox).  Covers Rage Pros, Rage Mobility P/M, Rage XL, and some others.
- i915 driver files, which just need to get drm_drv.c fixed to allow attachment
  to the drmsub device.  Covers i830 through i915 integrated graphics.
- savage driver files, which should require minimal changes to work.  Covers the
  Savage3D, Savage IX/MX, Savage 4, ProSavage.
- Support for color and texture tiling and HyperZ features of Radeon.

c6a37e8413 Divorce critical sections from spinlocks. Critical sections as denoted by
critical_enter() and critical_exit() are now solely a mechanism for
deferring kernel preemptions.  They no longer have any affect on
interrupts.  This means that standalone critical sections are now very
cheap as they are simply unlocked integer increments and decrements for the
common case.

Spin mutexes now use a separate KPI implemented in MD code: spinlock_enter()
and spinlock_exit().  This KPI is responsible for providing whatever MD
guarantees are needed to ensure that a thread holding a spin lock won't
be preempted by any other code that will try to lock the same lock.  For
now all archs continue to block interrupts in a "spinlock section" as they
did formerly in all critical sections.  Note that I've also taken this
opportunity to push a few things into MD code rather than MI.  For example,
critical_fork_exit() no longer exists.  Instead, MD code ensures that new
threads have the correct state when they are created.  Also, we no longer
try to fixup the idlethreads for APs in MI code.  Instead, each arch sets
the initial curthread and adjusts the state of the idle thread it borrows
in order to perform the initial context switch.

This change is largely a big NOP, but the cleaner separation it provides
will allow for more efficient alternative locking schemes in other parts
of the kernel (bare critical sections rather than per-CPU spin mutexes
for per-CPU data for example).

3df129097b The file machine/ieeefp.h needs sys/cdefs.h on amd64 and i386 after my
compiler features tests. This is ok, since machine/ieeefp.h is an internal
interface. But floatingpoint.h is a public interface and some ports use it,
so include sys/cdefs.h in the amd64 and i386 version of floatingpoint.h.

Note: some architectures don't provide recursive inclusion protection in
floatingpoint.h, namely alpha and ia64. Except for this part and now the
include of sys/cdefs.h, all those files are equal (from a compiler POV),
so they could be moved to only one version in src/include/.

503e759c5d MFR5: rev 1.421.2.6: Enable support for 32-bit Linux binaries by default.
There are too many questions in freebsd-amd64@ about how to enable Linux
support that it seems a required piece of functionality.  Thus we should
just have it on by default.

58aa36f31e Checkpoint today's tidy-up of the WIP disassembler. It now agrees with
objdump --disassemble when disassembling itself in userland.  I've added
the cmovCC instruction group and tweaked a bunch of size sensitive array
indexes to either fix my mistakes and/or force it to work by any means
necessary.

I'm committing this because it is usable enough to see what is going on
when single stepping via ddb.

It might still tell lies, but its lies will be far more subtle now.  I'm
not sure that this is a good thing or not.

f2c7668eb1 Make ps_nargvstr and ps_nenvstr unsigned. This fixes an input
validation error in procfs/linprocfs that can be exploited by local
users to cause a kernel panic.  All versions of FreeBSD with the patch
referenced in SA-04:17.procfs have this bug, but versions without that
patch have a more serious bug instead.  This problem only affects
systems on which procfs or linprocfs is mounted.

7b74e4a759 Remove fpsetsticky(). This was added for SysV compatibility, but due
to mistakes from day 1, it has always had semantics inconsistent with
SVR4 and its successors.  In particular, given argument M:

- On Solaris and FreeBSD/{alpha,sparc64}, it clobbers the old flags
  and *sets* the new flag word to M.  (NetBSD, too?)
- On FreeBSD/{amd64,i386}, it *clears* the flags that are specified in M
  and leaves the remaining flags unchanged (modulo a small bug on amd64.)
- On FreeBSD/ia64, it is not implemented.

There is no way to fix fpsetsticky() to DTRT for both old FreeBSD apps
and apps ported from other operating systems, so the best approach
seems to be to kill the function and fix any apps that break.  I
couldn't find any ports that use it, and any such ports would already
be broken on FreeBSD/ia64 and Linux anyway.

By the way, the routine has always been undocumented in FreeBSD,
except for an MLINK to a manpage that doesn't describe it.  This
manpage has stated since 5.3-RELEASE that the functions it describes
are deprecated, so that must mean that functions that it is *supposed*
to describe but doesn't are even *more* deprecated.  ;-)

Note that fpresetsticky() has been retained on FreeBSD/i386.  As far
as I can tell, no other operating systems or ports of FreeBSD
implement it, so there's nothing for it to be inconsistent with.

5974e5c71c Refactor the bus_dma header files so that the interface is described in
sys/bus_dma.h instead of being copied in every single arch.  This slightly
reorders a flag that was specific to AXP and thus changes the ABI there.
The interface still relies on bus_space definitions found in <machine/bus.h>
so it cannot be included on its own yet, but that will be fixed at a later
date.  Add an MD <machine/bus_dma.h> for ever arch for consistency and to
allow for future MD augmentation of the API.  sparc64 makes heavy use of
this right now due to its different bus_dma implemenation.

a5f50ef9e4 netchild's mega-patch to isolate compiler dependencies into a central
place.

This moves the dependency on GCC's and other compiler's features into
the central sys/cdefs.h file, while the individual source files can
then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to
refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42.

By now, GCC and ICC (the Intel compiler) have been actively tested on
IA32 platforms by netchild.  Extension to other compilers is supposed
to be possible, of course.
