Modified the subsystem initialization sequence to improve GPE support. The GPE initialization has been split into two parts in order to defer execution of the _PRW methods (Power Resources for Wake) until after the hardware is fully initialized and the SCI handler is installed. This allows the _PRW methods to access fields protected by the Global Lock. This will fix systems where a NO_GLOBAL_LOCK exception has been seen during initialization. Fixed a regression with the ConcatenateResTemplate() ASL operator introduced in the 20051021 release. Implemented support for "local" internal ACPI object types within the debugger "Object" command and the acpi_walk_namespace() external interfaces. These local types include RegionFields, BankFields, IndexFields, Alias, and reference objects. Moved common AML resource handling code into a new file, "utresrc.c". This code is shared by both the Resource Manager and the AML Debugger. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

Implemented support for the EM64T and other x86_64 processors. This essentially entails recognizing that these processors support non-aligned memory transfers. Previously, all 64-bit processors were assumed to lack hardware support for non-aligned transfers. Completed conversion of the Resource Manager to nearly full table-driven operation. Specifically, the resource conversion code (convert AML to internal format and the reverse) and the debug code to dump internal resource descriptors are fully table-driven, reducing code and data size and improving maintainability. The OSL interfaces for Acquire and Release Lock now use a 64-bit flag word on 64-bit processors instead of a fixed 32-bit word. (Alexey Starikovskiy) Implemented support within the resource conversion code for the Type-Specific byte within the various ACPI 3.0 *WordSpace macros. Fixed some issues within the resource conversion code for the type-specific flags for both Memory and I/O address resource descriptors. For Memory, implemented support for the MTP and TTP flags. For I/O, split the TRS and TTP flags into two separate fields. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2005-12-10[ACPI] ACPICA 20050930Bob Moore
Completed a major overhaul of the Resource Manager code - specifically, optimizations in the area of the AML/internal resource conversion code. The code has been optimized to simplify and eliminate duplicated code, CPU stack use has been decreased by optimizing function parameters and local variables, and naming conventions across the manager have been standardized for clarity and ease of maintenance (this includes function, parameter, variable, and struct/typedef names.) All Resource Manager dispatch and information tables have been moved to a single location for clarity and ease of maintenance. One new file was created, named "rsinfo.c". The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to guarantee that the argument is not evaluated twice, making them less prone to macro side-effects. However, since there exists the possibility of additional stack use if a particular compiler cannot optimize them (such as in the debug generation case), the original macros are optionally available. Note that some invocations of the return_VALUE macro may now cause size mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to eliminate these. (From Randy Dunlap) Implemented a new mechanism to enable debug tracing for individual control methods. A new external interface, acpi_debug_trace(), is provided to enable this mechanism. The intent is to allow the host OS to easily enable and disable tracing for problematic control methods. This interface can be easily exposed to a user or debugger interface if desired. See the file psxface.c for details. acpi_ut_callocate() will now return a valid pointer if a length of zero is specified - a length of one is used and a warning is issued. This matches the behavior of acpi_ut_allocate(). Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2005-12-03Link USB drivers later in the kernelLinus Torvalds
We want to link the "regular" SCSI drivers before the USB storage driver, since historically we've always detected internal SCSI disks before the external USB storage modules. The link order matters for initcall ordering, and this got broken by mistake by commit 7586269c0b52970f60bb69fcb86e765fc1d72309 which moved the USB host controller PCI quirk handling around.

Commit 64c7c8f88559624abdbe12b5da6502e8879f8d28 broke the ACPI C2 and C3 sleep states, because it left TIF_POLLING_NRFLAG active even though those states do not actually poll the reschedule flag at all. As a result, the CPU wouldn't get sent an IPI when it was to be woken up, and would only notice that it had runnable processes on the next timer tick.

2005-12-02[SCSI] sg: fix a bug in st_map_user_pages failure pathHugh Dickins
sg's st_map_user_pages is modelled on an earlier version of st's sgl_map_user_pages, and has the same bug: if get_user_pages got some but not all of the pages, then those got were released, but the positive res code returned implied that they were still to be freed.

2005-12-02[SCSI] sg and st unmap_user_pages allow PageReservedHugh Dickins
2.6.15-rc1 made sg's st_unmap_user_pages and st's sgl_unmap_user_pages BUG on a PageReserved page. But that's wrong: they could be unmapping the ZERO_PAGE, which is marked PG_reserved; and perhaps others (while get_user_pages is still permitted on VM_PFNMAP areas - that may change). More change is needed here: sg claims to dirty even pages written from, and st claims not to dirty even pages read into; and SetPageDirty is not adequate for this nowadays. Fixes to those follow in a later patch: for the moment just fix the 2.6.15 regression.

2005-12-01[SCSI] st: fix a bug in sgl_map_user_pages failure path Hugh Dickins
Nick and I had already been looking at drivers/scsi/{sg.c,st.c}, brought there by __put_page in sg.c's peculiar sg_rb_correct4mmap, which we'd like to remove. But that's irrelevant to your pain, except... One extract from the patches I'd like to send Doug and Kai for 2.6.15 or 2.6.16 is this below: since the incomplete get_user_pages path omits to reset res, but has already released all the pages, it will result in premature freeing of user pages, and behaviour just like you've seen. Though I'd have thought incomplete get_user_pages was an exceptional case, and a bit surprised you'd encounter it. Perhaps there's some other premature freeing in the driver, and this instance has nothing whatever to do with it. If the problem were easily reproducible, it'd be great if you could try this patch; but I think you've said it's not :-( Signed-off-by: Kai Makisara <kai.makisara@kolumbus.fi> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
