not optimal from a performance standpoint since the write buffer is
not necessarily be filled up when the inflate rountine reached the
end of input buffer and it's not the end of file.
This problem gets uncovered by trying to pipe gunzip -c output to
a GEOM device directly, which enforces the writes be multiple of
sector size.

driver-maintained ifnet fields (such as if_drv_flags).
- Use soft locks as the mutex that protects each interface's knote list
rather than using the global knote list lock. Also, use the softc
for kn_hook instead of the cdev.
- Use mtx_sleep() instead of tsleep() when blocking in the read routines.
This fixes a lost wakeup race.
- Remove D_NEEDGIANT now that the cdevsw routines use the softc lock
where locking is needed.
- Lock IFQ when calculating the result for FIONREAD in tap(4). tun(4)
already did this.
- Remove remaining spl calls.

This way the primary process inherits signal mask from the main process,
which fixes a race where signal is delivered to the primary process before
configuring signal mask.

while the main process sends control message to the worker process, but worker
process hasn't started control thread yet, because it waits for reply from the
main process.
The fix is to start the control thread before sending any events.

This is a followup to r212964.
stack_print call chain obtains linker sx lock and thus potentially may
lead to a deadlock depending on a kind of a panic.
stack_print_ddb doesn't acquire any locks and it doesn't use any
facilities of ddb backend.
Using stack_print_ddb outside of DDB ifdef required taking a number of
helper functions from under it as well.
It is a good idea to rename linker_ddb_* and stack_*_ddb functions to
have 'unlocked' component in their name instead of 'ddb', because those
functions do not use any DDB services, but instead they provide unlocked
access to linker symbol information. The latter was previously needed
only for DDB, hence the 'ddb' name component.
Alternative is to ditch unlocked versions altogether after implementing
proper panic handling:
1. stop other cpus upon a panic
2. make all non-spinlock lock operations (mutex, sx, rwlock) be a no-op
when panicstr != NULL

There has been no need to do that starting with ACPICA 20040427 as
AcpiEnableSubsystem() installs the handlers automatically.
Additionaly, explicitly calling AcpiInstallAddressSpaceHandler before
AcpiEnableSubsystem is not supported by ACPICA and leads to too early
execution of _REG methods in some DSDTs, which may result in problems.
Big thanks to Robert Moore of ACPICA/Intel for explaining the above.

slice they are on. When NANO_LABEL is not defined, the fstab
generates entries that specify /dev/ad0s1a. When NANO_LABEL is
defined, it generates /dev/usb/${NANO_LABEL}s1a. The prior code
created the file system with a label of ${NANO_LABEL}s1, leading to
problems on boot.

and sys/boot/pc98/boot2, do not simply assign 'gcc' to CC, since compile
flags are sometimes passed via this variable, for example during the
build32 stage on amd64. This caused the 32-bit libobjc build on amd64
to fail.
Instead, only replace the first instance of clang (if any, including
optional path) with gcc, and leave the arguments alone.

Reorder inline assembly arguments temp2, temp, value and texp to follow
the st(0), st(1), etc. style.
Also mark the temp2 variable as volatile to workaround another clang
bug.
This allows clang to buildworld FreeBSD/i386.

If timer capabilities forcing us to change periodicity mode, try to restore
it back later, as soon as new choosen timer capable to do it. Without this,
timer change like HPET->RTC->HPET always results in enabling periodic mode.
code:
- Accept devfs_mount and devfs_dirent as the arguments instead of a
vnode. This generalizes the function so that it can be used from
contexts where vnode references are not available.
- Accept NULL cnp argument. No '/' will be appended, if a NULL cnp is
provided.
- Make the function global and add its prototype to devfs.h.

the first line of a script exceeded MAXSHELLCMDLEN characters, then
exec_imgact_shell() silently truncated the line and passed on the truncated
interpreter name or argument. Now, exec_imgact_shell() will fail and return
ENOEXEC, which is the commonly used errno among Unix variants for this type
of error. (2) Previously, exec_imgact_shell()'s check on the length of the
interpreter's name was ineffective. In other words, exec_imgact_shell()
could not possibly fail and return ENAMETOOLONG. The reason being that the
length of the interpreter name had to exceed MAXSHELLCMDLEN characters in
order that ENAMETOOLONG be returned. But, the search for the end of the
interpreter name stops after at most MAXSHELLCMDLEN - 2 characters are
scanned. (In the end, this particular error is eventually discovered
outside of exec_imgact_shell() and ENAMETOOLONG is returned. So, the real
effect of this second change is that the error is detected earlier, in
exec_imgact_shell().)
Update the definition of MAXINTERP to the actual limit on the size of
the interpreter name that has been in effect since r142453 (from
2005).

The idea is to add KDB and KDB_TRACE options to GENERIC kernels on
stable branches, so that at least the minimal information is produced
for non-specific panics like traps on page faults.
The GENERICs in stable branches seem to already include STACK option.
