Correct an issue with the IPMI message layer taking a lock and calling
lower layer driver. If an error occrues at the lower layer the lock can be
taken again causing a deadlock. The lock is released before calling the
lower layer.

Enable interrupts for a BT interface. There is a specific register that
needs to be set up to enable interrupts that also must be modified to clear
the irq.
Also, don't reset the BMC on a BT interface. That's probably not a good
idea as the BMC may be performing other important functions and a reset
should only be a last resort. Also, that register is also used to
enable/disable interrupts to the BT; modifying it may screw up the
interrupts.

If there is an unexpected close, still allow the watchdog interface to be
re-opened on the IPMI watchdog.

If the ACPI register bit width is zero (an invalid value) assume it is the
default spacing. This avoids some coredumps on invalid data and makes some
systems work that have broken ACPI data.

Ignore the bottom bit of the base address from the DMI data. It is
supposed to be set to 1 if it is I/O space. Few systems do this, but this
enables the ones that do set it to work properly.

This patch changes calls to synchronize_kernel(), deprecated in the earlier
"Deprecate synchronize_kernel, GPL replacement" patch to instead call the new
synchronize_rcu() and synchronize_sched() APIs.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
