src/sys/dev/pci: ichsmb.c piixpm.c
Log Message:
Make ichsmb and piixpm MP-safe:
- Synchronize with the interrupt handler using a mutex.
- Use a condvar to wait for completion, rather than tsleep().
- Mark our interrupt handler as such.
Also, other general correctness fixes:
- Loop around testing the completion condition to protect aginst
spurious wakes.
- The "i2c exec" function returns an error code, so actually do so.
