avoid an error in the recent sys/evcnt.h change to drop the 0
array size from evcnt_sysctl:ev_strings that clang does not like.

the previous "struct xevcnt_sysctl" was well defined as the
evcnt_sysctl with array length of 0 could be placed as the
anywhere in other structures, but with [] it must remain last
and xevcnt_sysctl then places a char array afterwards.

avoid this entirely by removing struct xevcnt_sysctl, combining
the string array + struct evcnt_sysctl size manually for the
allocation, and moving all "ev_string" accesses to be via the
new [] array.

intrcnt[] is changed from long to u_int. Use sizeof(var) instead of
sizeof(type) to catch up with this change.

No binary changes as all ports with __HAVE_LEGACY_INTRCNT are ILP32, IIUC.

Make extern declaration of intrcnt a u_int instead of a long.  Matches
some declartions in some ports.  Fixes build on news68k (and probably
newsmips).

Expose olde style intrcnt interrupt accounting via event counters.
This code will be garbage collected once our last legacy intrcnt
user is update to native evcnts.

Apply patch (requested by maxv in ticket #1106):
Fix kernel information leak.

Sync with HEAD, resolve a couple of conflicts

Fix kernel pointer leaks in sysctl_doevcnt.

While here also fix info leak; there is a big padding so use zalloc.

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

sync with head

Fix infinite recursion.

Ensure that the top level sysctl nodes (kern, vfs, net, ...) exist before
the sysctl link sets are processed, and remove redundancy.

Shaves >13kB off of an amd64 GENERIC, not to mention >1k duplicate
lines of code.

Add evcnt_attach_dynamic_nozero

Modify *ASSERTMSG() so they are now used as variadic macros. The main goal
is to provide routines that do as KASSERT(9) says: append a message
to the panic format string when the assertion triggers, with optional
arguments.

Fix call sites to reflect the new definition.

Discussed on tech-kern@. See
http://mail-index.netbsd.org/tech-kern/2011/09/07/msg011427.html

check that we have valid event strings on attach too, so that the error
is obvious instead of catching it when vmstat -e runs!

- remove leftover debug print

- add evcnt_lock and use to protect the 'allevents' list
(pulled back fromk -current)

Add a sysctl to retrieve evcnts from the kernel.  You can tell it to
limit to a specific type and/or all or just evcnts with non-zero counts.

Add code to detect attaching of evcnt before evcnt has been initialized.

Add evcnt_attach_dynamic_nozero which doesn't zero it's contents.  This is
needed if the evcnt starts counting before it's attached (otherwise the
count would be zeroed and those events lost).

Add evcnt_attach_dynamic_nozero, a version of evcnt_attach_dynamic, which
doesn't zero the evcnt before filling in things.  This is needed when the
evcnt itself is being updated before evcnt_attach_dynamic can be called.

Commit is split, to avoid a "too many arguments" protocol error.

protect allevents list with a mutex

Make 'show event', 'dmesg' work with crash(8).
XXX dmesg fails exactly the same way as /sbin/dmesg.

Hi Perry!

file subr_evcnt.c was added on branch ktrace-lwp on 2004-08-03 10:52:55 +0000

Include "sys/systm.h" to get the prototype for panic() which is required
for diagnostic kernels.

split off the evcnt code (which is unrelated to autoconfiguration)
into a separate file
