return an error or the firmware enters a reset loop.

As pointed out by hselasky@, USB_IF_CSI is the wrong macro here since we want
to declare the device's interface class, subclass and protocol, not class,
subclass and driver info.

litteral for a path that does heavyweight stuff anyway (like lock acq),
at the price of obfuscated code.
Use the appropriate check where necessary and remove a macro.

Avoid function inlining for t1_bkpt_t on which we set a breakpoint.
Otherwise the address of the function is never called thus the
breakpoint never triggers.

Accessing sys_siglist directly requires rtld to copy it from libc to the sh
executable's BSS. Also, strsignal() will put in the signal number for
unknown signals (FreeBSD-specific) so we need not do that ourselves.
Unfortunately, there is no function for sys_signame.

This allows external scripts to control demotion factor together

all interested parties in case if interface flag IFF_UP has changed.
However, not only SIOCSIFFLAGS can raise the flag, but SIOCAIFADDR
and SIOCAIFADDR_IN6 can, too. The actual |= is done not in the protocol
code, but in code of interface drivers. To fix this historical layering
violation, we will check whether ifp->if_ioctl(SIOCSIFADDR) raised the
IFF_UP flag, and if it did, run the if_up() handler.
This fixes configuring an address under CARP control on an interface
that was initially !IFF_UP.
P.S. I intentionally omitted handling the IFF_SMART flag. This flag was
never ever used in any driver since it was introduced, and since it
means another layering violation, it should be garbage collected instead
of pretended to be supported.
- Use spinlock_enter()/spinlock_exit() to prevent a thread holding a
debug lock from being preempted to prevent other threads waiting
on that lock from starvation.
- Handle the possibility of CPU migration in between the fetch of curcpu
and the call to spinlock_enter() by saving curcpu in a local variable.
- Use memory barriers to prevent reordering of loads and stores of the
data protected by the lock outside of the critical section
- Eliminate false sharing of the locks by moving them into the structures
that they protect and aligning them to a cacheline boundary.
- Record the owning thread in the lock to make debugging future problems
easier.

credential cache files with names other than /tmp/krb5cc_<uid>.
The gssd daemon does not know how to find these credential caches.
This patch implements a new option "-s" that does a search for
credential cache files, using roughly the same algorithm as the
gssd daemon for Linux uses. The gssd behaviour is only changed
if the new "-s" option is specified. It also implements two other
new options related to the "-s" option.

Fix another SROA crasher, PR14601.
This was a silly oversight, we weren't pruning allocas which were used
by variable-length memory intrinsics from the set that could be widened
and promoted as integers. Fix that.
