There is another instance of CFILES which might need the same treatment,
and might be noticed when doing a "make links".
The same has to be done in RELENG_4 (on some different file).

It doesn't actually do it yet though. This adds a flag to config so
that we can exclude certain vendor files from this even when the rest
of the kernel has it on. make -DNO_WERROR would also bypass all of it.
buffer length, determine if the pointer is to a valid string. Currently,
the only check is whether a '\0' appears in the buffer. This is useful
when pulling in a structure from userland that may contain one or more
strings, and validity testing must be performed on elements of the
structure. When copying normal string arguments, copyinstr() is
expected to be used.
the structure definitions come from NetBSD to make it easier to share card
definitions. The driver only acts as a shim between the pci bus and the
sio driver. Later pci parallel ports could also be supported through this
driver. Support for most single and multiport pci serial cards should be
as simple as adding its definition to pucdata.c
Tested with the following pci cards:
Moxa Industio CP-114, 4 port RS-232,RS-422/485
Syba Tech Ltd. PCI-4S2P-550-ECP, 4 port RS-232 + 2 parallel ports

npx is no more mandatory than sc. Its mandatoryness went away in
rev.1.226 of i386/machdep.c 9 months before it was made mandatory in
rev.1.24 of config/mkmakefile.c.
This change is mainly to test building of minimal kernel configurations.
npx should really be even more standard than clk. It was optional mainly
so that the usual device driver configuration info could be specified in
the usual way in config files, but this hasn't been necessary for a few
years.

defined, no symbols are exported from the module. This is
the typical configuration for most device drivers and
standalone modules; only infrastructure modules or those with
special requirements typically need to export symbols.
Don't print the objcopy commands as they are run when converting
symbols; they're bulky and annoying in many cases.
simplifying the module linking process and eliminating the risks
associated with doubly-defined variables.
Cases where commons were legitimately used (detection of
compiled-in subsystems) have been converted to use sysinits, and
any new code should use this or an equivalent practice as a
matter of course.
Modules can override this behaviour by substituting -fno-common
out of ${CFLAGS} in cases where commons are necessary
(eg. third-party object modules). Commons will be resolved and
allocated space when the kld is linked as part of the module
build process, so they will not pose a risk to the kernel or
other modules.
Provide a mechanism for controlling the export of symbols from
the module namespace. The EXPORT_SYMS variable may be set in the
Makefile to NO (export no symbols), a list of symbols to export,
or the name of a file containing a newline-seperated list of
symbols to be exported. Non-exported symbols are converted to
local symbols. If EXPORT_SYMS is not set, all global symbols are
currently exported. This behaviour is expected to change (to
exporting no symbols) once modules have been converted.

Remove the explicit call to aio_proc_rundown() from exit1(), instead AIO

Add functions at_exec(9), rm_at_exec(9) which function nearly the
same as at_exec(9) and rm_at_exec(9), these functions are called
on behalf of modules at the time of execve(2) after the image
activator has run.
Use a modified version of tegge's suggestion via at_exec(9) to close
an exploitable race in AIO.
Fix SYSCALL_MODULE_HELPER such that it's archetecuterally neutral,
the problem was that one had to pass it a paramater indicating the

it by using an inline version of the AS macro against the syscall

later.)
