 1.22  23-Jan-2021  christos Document via __HAVE_BUS_SPACE_8 platforms that implement bus_space_*_8
 1.21  12-Jun-2011  rmind branches: 1.21.66;
Welcome to 5.99.53! Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

Now that __HAVE_TIMECOUNTER and __HAVE_GENERIC_TODR are invariants,
remove the conditionals and the code associated with the undef case.
 1.19  17-Oct-2007  garbled branches: 1.19.2; 1.19.8;
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.
 1.18  14-Jul-2007  ad branches: 1.18.10;
Generic soft interrupts are mandatory.
 1.17  09-Sep-2006  tsutsui branches: 1.17.10; 1.17.18;
Switch hp300 to timecounter with MC6840 interval timer, which is
used for hardclcok(9). Old code is still left for reference.

XXX: possibly problematic if hardclock(9) is blocked more than 1/HZ,
XXX: but old microtime(9) implementation also had the similar problem.
 1.16  04-Sep-2006  tsutsui branches: 1.16.2;
Switch hp300 to MI todr.
 1.15  06-Dec-2005  tsutsui branches: 1.15.4; 1.15.8;
Use _HP300_FOO_H_ instead of _MACHINE_FOO_H_.
 1.14  18-Jan-2004  martin branches: 1.14.16;
Do not export __HAVE_RAS to userland. Applications are supposed to try
rasctl() and detect failure with EOPNOTSUPP.
 1.13  22-Sep-2002  simonb branches: 1.13.6;
Use "#define\t" instead of "#define ".
 1.12  28-Aug-2002  gmcgarry RAS support for m68k.
 1.11  28-Feb-2002  simonb branches: 1.11.8;
Use "#define<tab>".
 1.10  08-Dec-2001  gmcgarry softintr(9) interface for hp300
 1.9  01-Feb-2000  danw branches: 1.9.8; 1.9.12;
#define __HAVE_DEVICE_REGISTER on ports that have it, and check for
that, rather than a list of architecture defines, in config_attach
 1.8  17-Dec-1996  thorpej branches: 1.8.28;
Kill __BROKEN_INDIRECT_CONFIG
 1.7  05-Dec-1996  cgd First step inn removing config_scan() and the hacks that gave devices
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:

Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.
 1.6  06-Oct-1996  thorpej Nuke __BDEVSW_DUMP_OLD_TYPE.
 1.5  26-Jun-1995  cgd define __BDEVSW_DUMP_OLD_TYPE for ports where it's true. clean up
some m68k ports inclusion of common header.
 1.4  26-Oct-1994  cgd new RCS ID format.
 1.3  08-Jan-1994  cgd stubs which pint to m68k include
 1.2  22-May-1993  cgd add rcsids to everything and clean up headers
 1.1  13-May-1993  cgd branches: 1.1.1;
Initial revision
 1.1.1.1  13-May-1993  cgd add hp300 kernel files. generic kernel files might need some help...
 1.8.28.1  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
