The pci bus driver handles the power state, it also manages
configuration state saving and restoring for its child devices. Thus a
PCI device driver does not have to worry about those things. In fact, I
observe a hard system hang when trying to suspend a system with active
radeonkms driver where both the bus driver and radeonkms driver try to
do the same thing. I suspect that it could be because of an access to a
PCI configuration register after the device is placed into D3 state.

All requests arriving for processing after OFFLINE flag set are rejected
with BUSY status. Races around OFFLINE flag setting are closed by calling
taskqueue_drain_all().
in the routine, which queues an ERROR chunk, instead on relyinh
on the callers to do so. Since one caller missed this, this actially

at the end of string buffer, and the code context do expects this to behave
correctly (e.g. strchr).
Note that we do not believe there is real-world impact for gstat(8)'s usage
because the strings are length checked, and the on-stack buffer belongs to
main() and we can expect to have zeros in them.

running thread.
It is currently implemented only on amd64 and i386; on these
architectures, it is implemented by raising an NMI on the CPU on which
the target thread is currently running. Unlike stack_save_td(), it may
fail, for example if the thread is running in user mode.
This change also modifies the kern.proc.kstack sysctl to use this function,
so that stacks of running threads are shown in the output of "procstat -kk".
This is handy for debugging threads that are stuck in a busy loop.

CTL HA functionality was originally implemented by Copan many years ago,
but large part of the sources was never published. This change includes
clean room implementation of the missing code and fixes for many bugs.
This code supports dual-node HA with ALUA in four modes:
- Active/Unavailable without interlink between nodes;
- Active/Standby with second node handling only basic LUN discovery and
reservation, synchronizing with the first node through the interlink;
- Active/Active with both nodes processing commands and accessing the
backing storage, synchronizing with the first node through the interlink;
- Active/Active with second node working as proxy, transfering all
commands to the first node for execution through the interlink.
Unlike original Copan's implementation, depending on specific hardware,
this code uses simple custom TCP-based protocol for interlink. It has
no authentication, so it should never be enabled on public interfaces.
The code may still need some polishing, but generally it is functional.

This silence a warning brought up by valgrind whenever if_nametoindex
is used. This was already discussed in PR 166483, but the code
committed in r234329 guards the initilization with #ifdef PURIFY.
Therefore, valgrind still complains. Since this code is not performance
critical, always zero out the local variable to silence valgrind.
