of the functions in libkern. Without this, parts of the kernel would
reference a non-existent (undeclared and undefined) ffs() function; the
only reason this didn't break the kernel build is that gcc happens to
have a built-in ffs() and incorrectly fails to warn about the lack of
prototypes for built-in functions.
ithread_remove_handler() may fail to remove the interrupt handler if
it decides to let the ithread do the removal. The problem is that during
boot "cold" is set, which causes msleep() to return immediately. This
will cause ithread_remove_handler() to fail to wait for the ithread
to do the removal from the handler TAILQ before freeing the handler
back to the heap. Bad things will happen when some other user of the
TAILQ, such as ithread_add_handler() or the actual ithread attempts to use
the freed handler. Fix the problem by forcing ithread_remove_handler()
to do the actual removal itself if the "cold" flag is set.

these sorts of make flags is actually the .MAKEFLAGS variable.
kmem_free(). Note: The FreeBSD-specific code in this file has been
subsumed by the FreeBSD-specific header file, pdq_freebsd.h. That header
file already specifies the use of contigmalloc() and contigfree(). Thus,
the purpose of this change is to avoid having nonsensical examples of
FreeBSD-specific memory allocation in our source tree.

and normally only they.
This can be useful in some random cases where it's necessary to
have something in .depend that isn't part of SRCS. This will be
used to replace a hack in lib/libpam/libpam/Makefile.
the MacIO chip and PSIM's IOBus. Bus-specific drivers should
use the identify method to attach themselves to nexus so
interrupt can be allocated before the h/w is probed. The
'early attach' routine in openpic is used for this stage
of boot. When h/w is probed, the openpic can be attached
properly. It will enable interrupts allocated prior to
this.
