a99d101352 * Remove __P and convert to ANSI prototypes.
* Remove 'register'.  (some functions had 7+ register functions...)
* Fix SCM ID's.

c447342094 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

9b801a0d86 Change a test for NETBSD_SYSCALLS to __alpha__. We're not ready to
do profiling on alpha yet.

37889b394a Changed to the C9x draft spelling of the (unsigned) integral type
suitable for holding object pointers (ptrint_t -> uintptr_t).
Added corresponding signed type (intptr_t).  Changed/added
corresponding non-C9x types for function pointers to match.  Don't
use nonstandard types to implement these types, and don't comment
on them in <machine/types.h>.

930a642372 Oops, fptrint_t still needs to be declared in <machine/profile.h> in the
!KERNEL case.  The kludge to get it declared in libc/gmon/mcount.c wasn't
sufficient because fptrint_t is used in <sys/gmon.h>.

2e480d34aa Added a kernel-only typedef (ptrint_t) giving an integral type that is
least unsuitable for holding an object pointer.  This should have been
used to fix warnings about casts between pointers and ints on alphas.

Moved corresponding existing general typedef (fptrint_t) for function
pointers from the i386 <machine/profile.h> to a kernel-only typedef
in <machine/types.h>.  Kludged libc/gmon/mcount.c so that it can
still see this typedef.

30ac8b16e2 These files are very specific to FreeBSD kernels, so silently compile
no code when building a library with __NETBSD_SYSCALLS defined.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

1f403fcfbf Cleaned up interrupt masking by declaring the state variable in a
machine-dependent macro and passing it to all machine-dependent
macros.

Eliminated the state variable for the GUPROF case.

912e603778 Implemented non-statistical kernel profiling. This is based on
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches.  The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.

gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes.  Does anyone
disagree?

gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header.  This
hack will do until then.  (Use gprof4 -u to examine the results
of non-statistical profiling.)

config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.

kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'.  `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.
