Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Remove an unnecessary INTR_MPSAFE and a comment suggesting it was
unnecessary.

Update d_mmap() to accept vm_ooffset_t and vm_memattr_t.

This replaces d_mmap() with the d_mmap2() implementation and also
changes the type of offset to vm_ooffset_t.

Purge d_mmap2().

All driver modules will need to be rebuilt since D_VERSION is also
bumped.

Use the new bus_space/resource convenience functions.

Instead of a rather useless generation number, use a sample number to
keep track of things.

Use BUS_PROBE_DEFAULT

Lock Giant around the body of the adlink_loran() function used by the

Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

The present defaults for the open and close for device drivers which
provide no methods does not make any sense, and is not used by any
driver.

It is a pretty hard to come up with even a theoretical concept of
a device driver which would always fail open and close with ENODEV.

Change the defaults to be nullopen() and nullclose() which simply
does nothing.

Remove explicit initializations to these from the drivers which
already used them.

Be less confusing in a comment.

Use __FBSDID().
Also some minor style cleanups.

Prefer new location for dev/pci/pci*.h

Boost sample rate to 1.25 MSPS since that allows us to use a 5Mhz

Make the interrupt both MPSAFE and FAST, at 610 interrupts a second,

Use kernel thread to accumulate into the 25 possible wave signals.

Use #ifdef _KERNEL to let .c file double as .h file defining the ioctls.
