7ee2912cf6 free() intrnamebuf, intrname and intrloc on entry so we don't leak them 
every time initvmstat() is called.
Change intrnamebuf to be static so this works.
Inspired by Coverty CID 2072 (incorrectly) reporting that the memory assigned
to intrnamebuf wasn't being freed.

1655d9a820 Code to display per-system call counts. 
Very useful to help identify which code is doing 1000s of system calls.
Not built because no one else has a kernel yet, and I need to make
the kernel side configurable.  But I don't want to lose this code....

efc0bc90c3 Count both read bytes and write bytes when we are not showing separate read 
and write statistics.  Discovered by go.
Since I broke in in rev 1.31, I guess I'll fix it first!

bee1c2beb6 Make the functions that display the top 8 lines externally visible so 
they can be used to head other pages (not ready to commit yet...).
Use puthumanint() for oversize numbers when display_mode is RUN or BOOT (when
very big numbers are to be expected).
Allow an extra column for Csw..Flt.
Adjust some #defines to avoid use of global s & s1.

0283f98333 Match changes to vmstat.c (splitting of dkreadstats). 
Read tape stats if there are no disks found - is this possible?

228802f437 Split dkreadstats() into dkreadstats(), tkreadstats() and cpureadstats(). 
Similarly for dkswap().
Allows code to only call one of these.
Rename struct _disk to _vminfo to be nearer its contents.
Change 'systat vm' so that it always shows the 'current' cpu times, even
after ':run' or ':boot' commands. The code in vmstat.c doesn't support :run.

Making ungetch() signal-safe, as ncurses seems to, would be better, though.

00b23860a0 "bufmem" is unsigned long inside the kernel, so don't try to grovel it out 
of kmem as a unsigned int.
Also avoid overrunning VCACHE_SIZE, thus scribling over unrelated memory.

caea20e952 Add PTRTOUINT64() and UINT64TOPTR() macros to sys/sysctl.h for use by 
kern.proc, kern.proc2, kern.lwp, and kern.buf.

Define more MIB for kern.buf so that specific buffers can be selected
(only all/all is supported right now), and use a 32/64 bit agnostic
structure for communcating buffer information to userland.

Convert systat to the new kern.buf method.

Clean up the vm.buf* handling a little.  There's no actual need to
record the dynamically assigned OIDs, since sysctl_data can tell us
what we're looking at.

Oh, and fix a typo in a comment.

498839ae5e Adapt to kernel buffer cache memort allocation changes. 
Since the buffer headers do no longer exist as an array in the kernel anymore,
use the new CTL_KERN.KERN_BUF mib to fetch them from kernel space.

Also look at a vnode's specinfo field to properly associate an opened
block device special file with a mounted filesystem.
