* ACPI: Move definition of PREFIX from acpi_bus.h to internal..hLen Brown2009-08-28
| | | | | | | | | | | | | 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. Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI: scheduling in atomic via acpi_evaluate_integer ()Pavel Machek2008-11-26
| | | | | | | | | | | | | | | Now I know why I had strange "scheduling in atomic" problems: acpi_evaluate_integer() does malloc(..., irqs_disabled() ? GFP_ATOMIC : GFP_KERNEL)... which is (of course) broken. There's no way to reliably tell if we need GFP_ATOMIC or not from code, this one for example fails to detect spinlocks held. Fortunately, allocation seems small enough to be done on stack. Signed-off-by: Pavel Machek <pavel@suse.cz> Acked-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI: Change acpi_evaluate_integer to support 64-bit on 32-bit kernelsMatthew Wilcox2008-10-11
| | | | | | | | | | | | | 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() Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPICA: Fixes for external Reference ObjectsBob Moore2008-04-22
| | | | | | | | | | | | All Reference Objects returned via the AcpiEvaluteObject interface are now marked as type "REFERENCE" instead of "ANY". The type ANY is now reservered for NULL objects - either NULL package elements or unresolved named references.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
