7194d335cf Run a revision of the devstat interface:
Kernel:

Change statistics to use the *uptime() timescale (ie: relative to
boottime) rather than the UTC aligned timescale.  This makes the
device statistics code oblivious to clock steps.

Change timestamps to bintime format, they are cheaper.

Remove the "busy_count", and replace it with two counter fields:
"start_count" and "end_count", which are updated in the down and
up paths respectively.  This removes the locking constraint on
devstat.

Add a timestamp argument to devstat_start_transaction(), this will
normally be a timestamp set by the *_bio() function in bp->bio_t0.
Use this field to calculate duration of I/O operations.

Add two timestamp arguments to devstat_end_transaction(), one is
the current time, a NULL pointer means "take timestamp yourself",
the other is the timestamp of when this transaction started (see
above).

Change calculation of busy_time to operate on "the salami principle":
Only when we are idle, which we can determine by the start+end
counts being identical, do we update the "busy_from" field in the
down path.  In the up path we accumulate the timeslice in busy_time
and update busy_from.

Change the byte_* and num_* fields into two arrays: bytes[] and
operations[].

Userland:

Change the misleading "busy_time" name to be called "snap_time" and
make the time long double since that is what most users need anyway,
fill it using clock_gettime(CLOCK_MONOTONIC) to put it on the same
timescale as the kernel fields.

Change devstat_compute_etime() to operate on struct bintime.

Remove the version 2 legacy interface: the change to bintime makes
compatibility far too expensive.

Fix a bug in systat's "vm" page where boot relative busy times would
be bogus.

Bump __FreeBSD_version to 500107

95ba428ccb The boottime variable in sys/kern/kern_tc.c is a struct timeval, not a
time_t, so do not use the latter as type when retrieving the variable

6f2671750e Remove malloc_type's ks_limit.
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.

e2cf520799 Fix a missed conversion of lld to llu for the uint64_t ks_calls and cast
to unsigned long long.

Don't be too overzealous with the printing of ks_calls in the total
statistics, cut back from 20 to 13 positions to print (which should last
a couple of years easily (20 digits is enough for 3168 years of calls at a
measly billion (10^9) calls per second.)).

6930c8618b Backed out the previous commit, except for the parts that reduced
the magicness of 200.  Cleaned up the remaining parts.  Circularisation
of the list of malloc types was a kernel bug (now fixed).  Interfering
with applications' definitions of pgtok is a system header bug (not
fixed).

7cbb70b303 Sometime since this file was written, the list of kernel malloc types
changed from a simple list to a circular one.  We compensate by only
looping until we see the first address again.  Before, things would
terminate because it was limited to 200 iterations.  This lead to
bogus statistics and repeating stats for memory types.

This should be merged into 3.2, as the same bug is there.

I'm not sure why we have `mvstat -z'.  `sysctl vm.zone' gives more

and reporting of memory use should be integrated, at least as an
