this used to be slightly cleaner than using ifdefs in a few places to
support both a.out and elf, but using it now just causes messes and
unportabilities. It seems to be impossible to implement the elf
HIDENAME() portably in cpp (since token pasting of "." and <name> is
invalid).

- Removed all uses of CNAME(). CNAME() is easy enough to use in pure
asm code, but using it in inline asm requires messy quoting. The
core pure asm code has been hacked on more and all uses of CNAME() in
it have already gone away. Just assume the elf convention here too.
- Removed now-uneeded include of <machine/asmacros.h>.
- Removed the workaround for a namespace conflict with this include.

Under certain circumstances (system high load, dummynet lock contention, etc)
dummynet's tick counter can be significantly slower than it should be.

Since this counter used for packet scheduling, it's accuracy is vital for
precise bandwidth limitation.
Introduce new sysctl nodes:
net.inet.ip.dummynet.
tick_lost - number of ticks coalesced by taskqueue thread.
tick_adjustment - number of time corrections done.
tick_diff - adjusted vs non-adjusted tick counter difference
tick_delta - last vs 'standard' tick differnece (usec).
tick_delta_sum - accumulated (and not corrected yet) time
difference (usec).

The 'nooption' kernel config entry has to be used to turn KSE off now.

experienced over that.

This change makes the transition from a default to an option more

i386). Use -mprofiler-epilogue again, and don't use -finstrument-functions.
The former has been fixed for arches that implement high-res profiling,
and the latter has been useless for kernel profiling since gcc-3.4
when it started forcing -fno-inline. -fno-inline gives a kernel with
performance characteristics too different from a normal kernel to be
worth profiling, by turning off inlining of all the little optimized
functions in headers. This interacts especially badly with FreeBSD's
use of "static inline" for all inlines in headers, by creating many
separate copies of the little functions, so not inlining tends to
increase cache pressure where it should reduce it, and (since gprof(1)
doesn't understand the copies) the statistics for the little functions
are hard to interpret even if you want them.

counters of allocs/frees/use for each malloc type to calculating InUse,
MemUse, and Requests as displayed by the userspace vmstat -m. This is
more useful when debugging malloc(9)-related memory leaks, where the
count of allocs/frees may not usefully reflect that current memory
allocation (i.e., when highly variable size allocations occur with the
same malloc type, such as with contigmalloc).

Limitations observed by: scottl
keyboard is attached only after the system has already booted.
If USB keyboard is also present, and there's no kbdmux(4), the problem
has been hiding itself because as soon as we get to multi-user, the
USB keyboard becomes an active keyboard (see devd.conf), thus marking
atkbd inactive and letting the old code initialize the keyboard.
With kbdmux(4), or if there's no USB keyboard, the atkbd keyboard is
always active, whether it's physically attached or not, thus it never
initialized itself properly on a physical attach.
To fix this, move block that initialized the keyboard on attach upper
so it doesn't depend on the (KBD_IS_ACTIVE(kbd) && KBD_IS_BUSY(kbd))
condition. Also move KBD_FOUND_DEVICE() a few lines upper so that
KDSETLED and KDSETREPEAT that follow it propagate to the controller.

understand that non-local variables can never be collected, and when
it collected the static variable for mexitcount_libfunc, gcc aborted
on the next use of this variable.
This quick fix is to reinitialize the variable on every use and depend
on garbage collection recovering the small amount of memory wasted by
this, and not worry by the small amount of time wasted by this. It
would be better to initialize the variable together with most of the
other libfuncs in optabs.c and depend on whatever magic is there to
prevent its collection, but we initialize it here to avoid taking at
least 2 more files off the vendor branch.

in /etc/fstab.
This has been happening due to the priority inversion; options
specified on the command line should take precedence over options
from fstab over default "noro" option, but since both the default
"noro" and options specified on the command line (-w, -r, -o ...)
were put into the same "options" variable, "noro" took precedence
over fstab "ro" (this is easily visible with "mount -d").
