Strip is often used to modify existing files, rather than creating new
files. If the existing file has hard links or is a symbolic link, act as

removed, introduce a new macro in bsd.sys.mk to choose the right variant
of compile flag for the used compiler, and use it.
Also add something similar to kern.mk, since including bsd.sys.mk from

Note that bsd.sys.mk does not support the MK_FORMAT_EXTENSIONS knob used
in kern.mk, since that knob is only available in kern.opts.mk, not in
src.opts.mk. We might want to add it later, to more easily support
external compilers for building world (in particular, sys/boot).

that tmpfs now performs scan on sync. Also, this means that a mtime
update may be delayed up to 30 seconds after the write.
The vm_object' OBJ_TMPFS_DIRTY flag for tmpfs swap object is similar
to the OBJ_MIGHTBEDIRTY flag for the vnode object, it indicates that
object could have been dirtied. Adapt fast page fault handler and

Garrett Cooper noticed that the overflow checks were incomplete, and Bruce
Evans suggested the use of the "volatile" qualifier to counter the effect
of the undefined behaviour, when the prior multiplication caused overflow,
and he also suggested improvements to the comments.

Also, split power_suspend into power_suspend and power_suspend_early.
power_suspend_early is called before the userland is frozen.
power_suspend is called after the userland is frozen.
Currently only VT switching is hooked to power_suspend_early.
This is needed because switching away from X server requires its
cooperation, so obviously X server must not be frozen when that happens.
Freezing userland during ACPI suspend is useful because not all drivers
correctly handle suspension concurrent with other activity. This is
especially applicable to drivers ported from other operating systems
that suspend all software activity between placing drivers and hardware
into suspended state.
In particular drm2/radeon (radeonkms) depends on the described
procedure. The driver does not have any internal synchronization
between suspension activities and processing of userland requests.
Many thanks to kib for the code that allows to freeze and thaw all
userland threads.
Note that ideally we also need to park / inhibit (non-special) kernel
threads as well to ensure that they do not call into drivers.

suspend/resume
The goal is to avoid that the vt(4) resume happens before the video
display is resumed. The original patch was provided by Andriy Gapon.
This new patch registers the handlers in vt_upgrade(). This is done
once, thanks to the VDF_ASYNC flag. I abused this flag because it was
already abused by the keyboard allocation. The event handlers then call
the backend if it provides callbacks for suspend/resume.

Previously, the driver resets the device and abandon the requests that
are caught in flight when the dump was initiated. This was problematic
if the system is resumed after the dump is completed.
While that is probably not the typical action, it is simple to rework
the driver to very likely have the device usable after the dump without
making it more likely for the dump to fail. The in flight requests are
simply queued for completion once the dump is finished.
