o) Set cache line size and latency timers for PCI devices per Linux.
o) Reset and configure the bus from scratch rather than expecting U-Boot to
do it for us. Values and configuration from Linux, U-Boot and comments
in the Cavium Simple Executive sources.
o) Do a resource assignment and bus numbering pass in the absence of a PCI
BIOS or firmware that will do it for us.
XXX This has to be the third or fourth instance of this in FreeBSD and
it would be nice to have it become part of the PCI bus driver itself,
like it is on Linux.

it hard to identify exact asic/chip revision so the first step to
debug bge(4) was getting exact asic/chip information with verbose
boot which may not be available on production server.

- 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 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.

flags are sometimes passed via this variable, for example during the

to fail.
Instead, only replace the first instance of clang (if any, including
optional path) with gcc, and leave the arguments alone.

- 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

- 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

The GENERICs in stable branches seem to already include STACK option.

is running on "dummy" time counter. But to function properly in one-shot
mode, event timer management code requires working time counter. Slow
moving "dummy" time counter delays first hardclock() call by few seconds
on my systems, even though timer interrupts were correctly kicking kernel.
That causes few seconds delay during boot with one-shot mode enabled.
To break this loop, explicitly call tc_windup() first time during
initialization process to let it switch to some real time counter.
