a192a9580b ACPI: Move definition of PREFIX from acpi_bus.h to internal..h
Linux/ACPI core files using internal.h all PREFIX "ACPI: ",
however, not all ACPI drivers use/want it -- and they
should not have to #undef PREFIX to define their own.

Add GPL commment to internal.h while we are there.

This does not change any actual console output,
asside from a whitespace fix.

27663c5855 ACPI: Change acpi_evaluate_integer to support 64-bit on 32-bit kernels
As of version 2.0, ACPI can return 64-bit integers.  The current
acpi_evaluate_integer only supports 64-bit integers on 64-bit platforms.
Change the argument to take a pointer to an acpi_integer so we support
64-bit integers on all platforms.

lenb: replaced use of "acpi_integer" with "unsigned long long"
lenb: fixed bug in acpi_thermal_trips_update()

Catch attempts to use of acpi_driver_data on pointers of wrong type.

akpm: rewritten to use proper C typechecking and remove the
"function"-used-as-lvalue thing.

266feefeb9 ACPI: Avoid bogus timeout about SMbus check
In the function of wait_transaction_complete when the timeout happens,
OS will try to check the status of SMbus again. If the status is what OS
expected, it will be regarded as the bogus timeout. Otherwise it will be
treated as ETIME.

bbafbecb24 ACPI: SBS: Host controller must initialize before SBS.
In static case sbshc must be compiled ahead of sbs, so that
hc is configured first.
