f60f21cf0b The remaining capacity percentage was incorrect for batteries larger than 
21.47 Wh becaue of integer overflow.

d62eb597a2 fix a few problems in the last commit: 
- make sure that the driver checks the battery presence at acpibat_update()
    if the battery has been not present, because the driver sometimes
    (i.e. boot time or resuming time) miss to sense the presence.
  - make sure that the driver always update the status at acpibat_gtredata();
    I misunderstood about ACPI_NOTIFY_BatteryStatusChanged event.

f27a62da88 - reduce the frequency of updating informations on the power sources; 
it is very slow to access to EC on some machines (i.e. CASIO FIVA 2xx).
- clean the flags up.
- add locks while updating informations.
- some cosmetic changes.

59e0238f99 add envsys support to acpi A/C adapter and batteries. This is still a work 
in progress, much like the rest of ACPI.

165d7516fb Again, in acpibat_get_status, bail rather than continuing if the package 
we receive contains less elements than expected.

46e00cd6f7 Oops, I didn't mean for that commented out verbose flag to make it into the 
last commit -- uncomment it again.

e49259c17a If we receive a battery information package with less than 13 elements, 
cleanup and return rather than trying to continue anyway.

64bf5ef14f Fix battery support (Masanori Kanaoka). 
XXX: ToDo: Still the battery charge is 96% when the battery is
fully charged on my libretto because of the estimated total charge offset.

6e12c44e0f - Fix typo in a message. 
- Avoid to divide by 0.
   When booting without battery, sc->sc_design_capacity become 0.

b8de140e4e Prototype ACPI Control Method Battery driver. 
ACPI defines two different battery device interfaces: "Control Method"
batteries, in which AML methods are defined in order to get battery
status and set battery alarm thresholds, and a "Smart Battery" device,
which is an SMbus device accessed through the ACPI Embedded Controller
device; this driver knows how to attach to the former sort of device.

As a total kludge, since we haven't wired things up to sysmon/envsys
yet, we report battery status through a once-per-minute kernel printf,
so don't use this driver yet if you want your disk to spin down.

Motivated by and tested on Sony PCG-R505TL laptop, which has
nonfunctional APM.

configure as:

acpibat* at acpi ?
