bouyer | Introduce smap_enable()/smap_disable() functions, to be used from
C code.

Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

ad | x86 changes for pcc and LKMs.
- Replace most inline assembly with proper functions. As a side effect
this reduces the size of amd64 GENERIC by about 120kB, and i386 by a
smaller amount. Nearly all of the inlines did something slow, or something
that does not need to be fast.
- Make curcpu() and curlwp functions proper, unless __GNUC__ && _KERNEL.
In that case make them inlines. Makes curlwp LKM and preemption safe.
- Make bus_space and bus_dma more LKM friendly.
- Share a few more files between the ports.
- Other minor changes.

fvdl | branches: 1.17.8; 1.17.10; 1.17.12;
Revert fs/gs changes until I figure out issues with them.
|
| 1.16 |
| 11-May-2007 |
fvdl | Don't save/restore %fs and %gs in trapframe. The kernel won't touch them.
Instead, save/restore them on context switch. For 32bit processes, save/restore
the selector values only, for 64bit processes, save/restore the appropriate
MSRs. Iff the defaults have been changed.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

ad | .. but only if _KERNEL is defined.
|
| 1.12 |
| 14-Jan-2007 |
ad | On second thought, implement x86_pause() as a regular function. The small
delay from the call is useful for spinlock backoff.
|
| 1.11 |
| 12-Jan-2007 |
ad | x86_pause(): do issue the 'pause' instruction, for EMT64 CPUs.
|

ad | Report on and where possible, try to work around some of the known errata
for Athlon 64 and Opteron processors. Tested briefly by cube@ and elad@.

fvdl | branches: 1.3.2;
Move x86_pause() out of ifdef _KERNEL.
|
| 1.2 |
| 08-May-2003 |
fvdl | Add x86_pause() inline function, containing the "pause" instruction
for i386, and nothing for amd64. Sprinkle it in various spinloops,
as recommended by Intel.
|
| 1.1 |
| 26-Apr-2003 |
fvdl | Rename the x86_64 port to amd64, as this is the actual name used for
the processor family now. x86_64 is kept as the MACHINE_ARCH value,
since it's already widely used (by e.g. the toolchain, etc), and
by other operating systems.

similar that use cmpxchg8b instead of cli/sti. Cuts the clock cycles for
splx() by a factor of ~6 on the P4, and ~3 on the PIII when bracketed by
serializing instructions (and hopefully more when not).
