On Core2 and older Intel CPUs, where TSC stops in C2, system does not
allow C2 entrance if timecounter hardware is TSC. This is done by
tc_windup() which tests for TC_FLAGS_C2STOP flag of the new
timecounter and increases cpu_disable_c2_sleep if flag is set. Right
now init_TSC_tc() only sets the flag if cpu_deepest_sleep >= 2, but
TSC is initialized too early for this variable to be set by
acpi_cpu.c.
There is no reason to require that ACPI reported C2 and deeper states
to set TC_FLAGS_C2STOP, so remove cpu_deepest_sleep test from
init_TSC_tc() condition. And since this is the only use of the
variable, remove it at all.

In vm_fault_prefault(), if backward count causes underflow in
calculation of
starta = addra - backward * PAGE_SIZE;
then starta must be clipped to entry->start, instead of zero.
Clipping to zero allowed mapping outside of the map entries address
ranges, in particular, map at zero.

Some APs broadcast WPS IE frames with totally broken data. Ifconfig's printwpsie()
loops through WPS frames printing the attributes out; if the frame's data is bad,
printwpsie() can end up looking at out-of-bounds addresses causing ifconfig to
bus error.
Thanks to Takashi Inoue at Nihon U for his efforts in debugging this.

Stop building BERI_DE4_BASE and BERI_SIM_BASE, they aren't particularly
valid as they don't have a root dev. Do build BERI_DE4_SDROOT which
does so devices get coverage.
Remove ident from BERI_DE4_BASE for the reasons above which will cause
it to fail to build. BERI_SIM_BASE was already this way and broke
universe.[0]

This function allows the caller to specify the reference clock
and choose between absolute and relative mode. In relative mode,
the remaining time can be returned.
The API is similar to clock_nanosleep(3). Thanks to Ed Schouten
for that suggestion.
While I'm here, reduce the sleep time in the semaphore "child"
test to greatly reduce its runtime. Also add a reasonable timeout.

least 2 * MSS. However, if the receive buffer size is small, this might
be impossible. Add back a criterion to send a TCP window update if
the window can be increased by at least half of the receive buffer size.
This condition was removed in r242252. This patch simply brings it back.

Most of these are null pointer dereferences or missing error checks in the
unit tests. One is a missing error check in xnb_attach_failed. None can

r275234 addressed sort automatically converting 8-bit locales to UTF-8
by using "LANG=C sort", but LC_ALL overrides LANG if set, so the issue
may still be present depending on the user's environment. Use LC_ALL=C

The blacklistd daemon keeps records of failed login attempts for
each address:port that is flagged as a failed login. When a
successful login occurs for that address:port combination,
the record's last update time is set to zero, to indicate no current
failed login attempts.
Reset the failed login count to zero, so that at the next failed
login attempt, the counting will restart properly at zero. Without
this reset to zero, the first failed login after a successful login
will cause the address to be blocked immediately.
When debugging is turned on, output more information about database
state before and after the database updates have occured.
A similar patch has already been upstreamed to NetBSD.
