Modified files:
sys/dev/acpica acpi_ec.c
Log:
Close a race condition by passing status retrieved via a non-SCI call
to EcGpeQueryHandler on to any waiting threads through the softc. Similar
behavior was in the original version.
Also:
* Merge EcQuery into EcGpeQueryHandler to simplify locking
* Hold EcLock from the initial read of the CSR down to the wakeup or
until after the query command has been processed.
* ec_gpebit only needs to be a UINT8
