The 'nooption' kernel config entry has to be used to turn KSE off now.
This isn't my preferred way of dealing with this, but I'll defer to
scottl's experience with the io/mem kernel option change and the grief
experienced over that.

This change makes the transition from a default to an option more
transparent and is an attempt to head off all the compliants that are
likely from people who don't read UPDATING, based on experience with
the io/mem change.

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.

doing second unlock.

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).

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.

real solution would be to have finer grained control in the stack over what
can and cannot be assisted in hardware.

(Previously the option was inherited from MI NOTES.) So my tool in

leaving the option effectively disabled as it was before, but since
it's actually supported on sparc64, turn it on now.

to and from struct timespec, to replace the crummy conversion
function which have been copy&pasted into three different
filesystems already.
Apart from general crummyness as indicated by code like:
for (year = 1970;; year++) {
inc = year & 0x03 ? 365 : 366;
if (days < inc)
break;
days -= inc;
}
They also contain specialized crummyness which tries to compensate
for the general crummyness by caching recent conversion results,
with no regard for locking or consistency.
These replacement functions are smaller, O(1) and handle the Y2.1K
leap-year correctly.
Ideally, these functions should live in a module of their own,
which the three offending filesystems would depend on, but the
size is 877 bytes of code (on i386), so that would be false
economy.
begun with a repo-copy of mac.h to mac_framework.h. sys/mac.h now
contains the userspace and user<->kernel API and definitions, with all
in-kernel interfaces moved to mac_framework.h, which is now included
across most of the kernel instead.
This change is the first step in a larger cleanup and sweep of MAC
Framework interfaces in the kernel, and will not be MFC'd.
