The pd_name field of struct pci_conf is an array, so it can never be null.

a55e34eb28 Rename the 'system' target to 'disc1', which is specific
to the disc1.iso installer image.

Replace 'system' with 'release' in CLEANFILES, and add
'disc1' to CLEANDIRS.

Ensure the 'dvd' target depends on 'packagesystem'.

Fix 'mini-memstick.img' prerequisite, which should be the
'bootonly' target, not 'disc1' (previously 'system').

Use .TARGET as the target installation directory for the
disc1.iso and bootonly.iso images, which now expand to
'disc1' and 'bootonly' respectively, mimicking the behavior
of the 'dvd' target.

Remove '@true' from the 'release' target, and instead use
'touch ${.TARGET}' to prevent multiple iterations of
'make release' from clobbering previously-built installer
medium.

f40cb1c645 Update mtime for tmpfs files modified through memory mapping. Similar
to UFS, perform updates during syncer scans, which in particular means
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
vm_object_set_writeable_dirty() to handle OBJ_TMPFS_NODE same as
OBJT_VNODE.

- Add special test to detect the case of -1 * INTMAX_MIN
- Protect against elimination of the test division by the optimizer

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.

85f95fffd7 hook userland threads suspend + resume into acpi suspend code
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.

6dfa4578d6 vt(4): Use power_{suspend,resume} event handlers to implement
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.

6b0e9233e4 Rework vtblk dump handling of in flight requests
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.

Allows Clang to use LLVM's fixes-x18 option

  This patch allows clang to have llvm reserve the x18
  platform register on AArch64. FreeBSD will use this in the kernel for
  per-cpu data but has no need to reserve this register in userland so
  will need this flag to reserve it.

  This uses llvm r226664 to allow this register to be reserved.
