Whitespace: #define<tab>

expose the kernel types for standalone code.

Hide {p,v}{addr,size}_t and register_t (and a couple more types that
are machine-specific) from userland unless _KERNEL/_KMEMUSER and a
new _KERNTYPES variables is defined. The _KERNTYPES should be fixed
for many subsystems that should not be using it (rump)...

Fix PTHREAD_FOO_INITIALIZER for C++ by not using volatile in the relevant
pthread types in C++ builds, attempt 2.

The problem with attempt 1 was making assumptions of what the MD
__cpu_simple_lock_t (declared volatile) looks like. To get a same type
except non-volatile, we change the MD type to __cpu_simple_lock_nv_t
and typedef __cpu_simple_lock_t as a volatile __cpu_simple_lock_nv_t.
IMO, __cpu_simple_lock_t should not be volatile at all, but changing it
now is too risky.

Fixes at least Rumprun w/ gcc 5.1/5.2. Furthermore, the mpd application
(and possibly others) will no longer require NetBSD-specific patches.

Tested: build.sh for i386, Rumprun for x86_64 w/ gcc 5.2.

Based on the patch from Christos in lib/49989.

branches: 1.47.6;
add #define __HAVE_MD_SOFTINT_TRIGGER to <vax/types.h>
Only define a function prototype for softint_trigger
if __HAVE_MD_SOFTINT_TRIGGER is undefined.

branches: 1.46.2; 1.46.4;
- Increase MAXPARTITIONS for vax from 8 to 16, using the standard NetBSD
mechanism to ensure all existing /dev nodes continue to work
- Adjust boot block layout to fit additional partitions
- Adjust number of inodes on install media

Implement __HAVE_RAS. Unlike most implementation, this is done in userret
instead of cpu_switchto since we already accessing the proc structure so
the additional overhead of check p_raslist is minimal.

branches: 1.44.2;
Introduce __HAVE_NO___THREAD for sun2 and vax to disable the TLS usage.
Require __HAVE_TLS_VARIANT_I or __HAVE_TLS_VARIANT_II as well as
__lwp_getprivate_fast / __lwp_gettcb_fast to exist for libpthread.
Define VAX as going to use TLS variant I, if it is ever implemented.

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.

device_t, cfdata_t, etc.
CFATTACH_DECL -> CFATTACH_DECL_NEW for sizeof(struct device).

branches: 1.41.2; 1.41.6;
Add a define __HAVE_CPU_DATA_FIRST which means that cpu_data is the first
member in struct cpu_info.

branches: 1.40.4;
Add PRIx{P,V}{ADDR,SIZE}, PRIu{P,V}SIZE, and PRIxREGISTER{,32,64} for all
(except where they will be added via merge). These should be used to print
{p,v}{addr,size}_t and register*_t as appropriate.

branches: 1.39.10;
Make NetBSD/vax work again. Add support for __HAVE_FAST_SOFTINTS.
Add a few small optimizations.

Now that __HAVE_TIMECOUNTER and __HAVE_GENERIC_TODR are invariants,
remove the conditionals and the code associated with the undef case.

Timecounter support for VAX. Basic testing in simh done on a backported
version to netbsd-4.

branches: 1.36.2; 1.36.8;
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.

branches: 1.35.10;
Generic soft interrupts are mandatory.

__HAVE_MD_RUNQUEUE is no longer relevant.

branches: 1.33.6; 1.33.8; 1.33.14;
Partially adapt the VAX port to the newlock2 changes. These are untested

Move __cpu_simple_lock_t and __SIMPLELOCK_{UN,}LOCKED to machine/types.h
so that they can be used in a namespace-friendly way.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

branches: 1.26.2;
Add a new feature-test macro, _NETBSD_SOURCE. If this is defined
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.

This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.

I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.

Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

Use "#define\t" instead of "#define ".

Add __HAVE_MD_RUNQUEUE flag for MD code to override MI run queue primitives.

* Move definitions of exact-width integer types from <machine/types.h>
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
intmax_t, pointer-type and size_t arguments.

branches: 1.20.2;
Rename __GENERIC_SOFT_INTERRUPTS to __HAVE_GENERIC_SOFT_INTERRUPTS,
and place the definition in <machine/types.h>. This can now be used
as a flag to indicate whether or not <machine/intr.h> can be included
to get the generic soft interrupt API.

replace 'long long' with int64_t to compile stand alone program with
compiler other than GCC.

expunge vm_offset_t and vm_size_t.
add bus_dma support for the vs4000 dma translation map (sgmap).
enhance the vsbus for the lance to work with it.
remove the sgmap init code from ka46/48/49.c

Remove __BROKEN_CONFIG_UNIT_USAGE.

add __BROKEN_CONFIG_UNIT_USAGE #define, becuase these ports do very
wrong things with device configuration data "cf_unit" information.

#define __HAVE_DEVICE_REGISTER on ports that have it, and check for
that, rather than a list of architecture defines, in config_attach

branches: 1.13.2;
GC the unused `physadr' type, which was not able to hold a complete physical
address on 2 architectures anyhow. Also, move the definition of the `label_t'
type inside _KERNEL protection, since it is specific to the in-kernel
setjmp()/longjmp() implementations.

Remove __BROKEN_INDIRECT_CONFIG and change all drivers to use
config_search instead.

Mark uses of long long with /* LONGLONG */ for lint. From
Chris Demetriou <cgd@pa.dec.com>.

branches: 1.10.14;
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.

Added prototypes to everything. Made all files compile with -Wall.

Enable label_t.

Remove __FORK_BRAINDAMAGE, and the reason to why it was there.

Define __FORK_BRAINDAMAGE.

add <sys/cdefs.h> inclusions. namsspace-protect physadr, label_t
def'ns against _POSIX_SOURCE and _ANSI_SOURCE.

define __BDEVSW_DUMP_OLD_TYPE for ports where it's true. clean up
some m68k ports inclusion of common header.

Lots of fixes...
