 1.19  21-Jan-2012  chs src/sys/dev/ic/mpu.c
fix assertions after audiomp.
 1.18  23-Nov-2011  jmcneill branches: 1.18.2;
Merge jmcneill-audiomp3 branch, which is derived from ad-audiomp2. From
the original ad-audiomp branch notes:

Add MP locking to the audio drivers.

Making the audio drivers MP safe is necessary before efforts
can be made to make the VM system MP safe.

The are two locks per device instance, an ISR lock and
a character device lock. The ISR lock replaces calls to
splaudio()/splx(), and will be held across calls to device
methods which were called at splaudio() before (e.g.
trigger_output). The character device lock is held across
calls to nearly all of the methods, excluding some only
used for initialization, e.g. get_locks.

Welcome to 5.99.57.

Update the mpu at eso attachment.
 1.1  01-Aug-1999  augustss Move the MPU driver isa/ to ic/.
(I didn't move it in the repository because the revision history
is very short and uninteresting. :)
 1.2.2.2  02-Aug-1999  thorpej Update from trunk.
 1.2.2.1  02-Aug-1999  thorpej file mpu.c was added on branch chs-ubc2 on 1999-08-02 21:59:05 +0000
 1.3.2.1  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.
