Exports some sensors through the envsys(4) framework available
in some Thinkpad laptops.
Ported by Pierre Pronchery from OpenBSD, via PR port-i386/36852.
Tweaks, LKM and misc improvements by me. Added into i386/GENERIC

This removes a hard limit that would prevent a guest from running with more
than 7 virtual network interface.
If running on a hypervisor that doesn't support GNTTABOP_query_size, fall back
to a 4-pages grant table, so this change is backward-compatible.

- Set correctly Ultra DMA and Multi-word DMA modes.
- Update comments to be more correct after reading again the datasheet.
transfer as a write to ensure the memory is writable before starting any
transfer. The fault status information does not reflect this in the 'read'
status bit (i.e. it shows up as a read access), so faults with a RMW access
to non-writable memory was not getting the correct protection. The page would
be read-only and the instruction would fault over and over.
A specific example is when a process forks, and the child process attempts
to execute a RMW access to a data page, which is read-only because it's CoP
Copy-On-Write.
When checking if the page needs to be writablek, also check the locked transfer
and treat any locked transfer as a write.
68060 already handled this correctly, since it has separate read and write
fault bits, and both are set on a RMW access and the trap code was checking
the write status bit.

it is easier to keep kernel configuration files up-to-date.
While we are here, disable a few compat options - NetBSD 1.5 has been
a while.
Tested on a Macintosh SE/30 with ae(4) ethernet card.

(A bazillion is a very large number. This seems to make the i386

types. C99 requires that these definitions promote to (signed/unsigned)
integer the same way as the types the definition is for. And since
unsigned char/short fit into an "int" on all our archs and thus promote
to signed int, the definitions must not be unsigned.
