Apply the change as a continuous slew rather than as a series of
discrete steps and make it possible to adjust arbitraryly huge
amounts of time in either direction.
In practice this is done by hooking into the same once-per-second
loop as the NTP PLL and setting a suitable frequency offset deducting
the amount slewed from the remainder. If the remaining delta is
larger than 1 second we slew at 5000PPM (5msec/sec), for a delta
less than a second we slew at 500PPM (500usec/sec) and for the last
one second period we will slew at whatever rate (less than 500PPM)
it takes to eliminate the delta entirely.
The old implementation stepped the clock a number of microseconds
every HZ to acheive the same effect, using the same rates of change.
Eliminate the global variables tickadj, tickdelta and timedelta and
their various use and initializations.
This removes the most significant obstacle to running timecounter and
NTP housekeeping from a timeout rather than hardclock.
that declares itself to be a disk, which may be the wrong thing to do in
the long term but it works well enough to attach to emulated disks in the
PowerPC simulator in gdb now that they have the proper device_type
property.
information related to bucket size effeciency. Three things are printed on
each row:
Size is the size the user actually asked for rounded to 16 bytes.
Requests is the number of times this size was asked for.
Real Size is the size we actually handed out.
At the end the total memory used and total waste is displayed. Currently my
system displays about 33% wasted memory.
The intent of this code is to gather statistics for tuning the malloc bucket
sizes. It is not intended to be run with INVARIANTS and it is not entirely
mp safe. It can be enabled via 'options MALLOC_PROFILE' which was commited
earlier.
Updated the kmemzones logic such that the ks_size bitmap can be used as an
index into it to report the size of the zone used.
Create the kern.malloc sysctl which replaces the kvm mechanism to report
similar data. This will provide an easy place for statistics aggregation if
malloc_type statistics become per cpu data.
Add some code ifdef'd under MALLOC_PROFILING to facilitate a tool for sizing
the malloc buckets.
collect2 was added based on the need of -frepo. However, -frepo is currently
broken on -CURRENT (Gcc 2.95.4 20020320 [FreeBSD] / ld 2.12.0 [FreeBSD]
2002-04-10). It is also broken on RELENG_4 (Gcc 2.95.3 20010315 / ld
2.11.2 20010719), so there is no need to MFC collect2 there yet. I have
a feeling the brokeness is due to the wide difference between the libiberty
bits of Gcc 2.95 and the later ld.

incorrect, however, as Dennis Ritchie states ``Actually the acronym is "block
started by symbol." It was a pseudo-op in FAP (Fortran Assembly Program), an
assembler for the IBM <models> machines. It identified its label and set
aside space for a given number of words.''
