Implemented support for Buffer and String objects (as per ACPI 2.0) for the following ASL operators: LEqual, LGreater, LLess, LGreaterEqual, and LLessEqual.

Completed a new design and implementation for EBDA (Extended BIOS Data Area) support in the RSDP scan code. The original code improperly scanned for the EBDA by simply scanning from memory location 0 to 0x400. The correct method is to first obtain the EBDA pointer from within the BIOS data area, then scan 1K of memory starting at the EBDA pointer. There appear to be few if any machines that place the RSDP in the EBDA, however. http://bugme.osdl.org/show_bug.cgi?id=2415 Integrated a fix for a possible fault during evaluation of BufferField arguments. Obsolete code that was causing the problem was removed. (Asus laptop boot crash) https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=121760 Found and fixed a problem in the Field Support Code where data could be corrupted on a bit field read that starts on an aligned boundary but does not end on an aligned boundary. Merged the read/write "datum length" calculation code into a common procedure.

Fixed a problem where hardware GPE enable bits sometimes not set properly during and after GPE method execution. Result of ACPICA 20040427 changes. Removed extra "clear all GPEs" when sleeping/waking. Removed acpi_ht_enable_gpe and acpi_hw_disable_gpe, replaced by the single acpi_hw_write_gpe_enable_reg. Changed a couple of calls to the functions above to the new acpi_ev* calls as appropriate. ACPI_OS_NAME was removed from the OS-specific headers. The default name is now "Microsoft Windows NT" for maximum compatibility. However this can be changed by modifying the acconfig.h file. Fixes EHCI probe issue: http://bugme.osdl.org/show_bug.cgi?id=1762 Allow a single invocation of acpi_install_notify_handler for a handler that traps both types of notifies (System, Device). Use ACPI_ALL_NOTIFY flag. Run _INI methods on ThermalZone objects. This is against the ACPI specification, but there is apparently ASL code in the field that has these _INI methods, and apparently "other" AML interpreters execute them. Performed a full 16/32/64 bit lint that resulted in some small changes.

discovered with IOAPIC disabled. The problem was that drivers/serial/8250_acpi.c found COM1 in the ACPI namespace and called acpi_register_gsi() to set up its IRQ. ACPI tells us that the COM1 IRQ is edge triggered, active high, but acpi_register_gsi() was ignoring the edge_level argument, so it blindly set the COM1 IRQ to be level-triggered.

I noticed that insert_resource() incorrectly handles the case of an existing parent resource with the same ending address as a newly added child. This results in incorrect nesting, like the following: # cat /proc/ioports <snip> 002f0000-002fffff : PCI Bus #48 00200000-002fffff : /pci@800000020000003 </snip> Signed-off-by: John Rose <johnrose@austin.ibm.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

PIO handlers under CONFIG_IDE_TASKFILE_IO=n are never used for bio based requests (rq->bio is always NULL) so we can use rq->buffer directly instead of calling ide_[un]map_buffer(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@elka.pw.edu.pl> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

These handlers are nowadays used only for REQ_DRIVE_TASKFILE requests (rq->bio is always NULL) which aren't retried et all so remove code 'rewinding' rq->current_nr_sectors and some FIXMEs.

- do not unregister ide-pnp driver while detaching random IDE device from random IDE device driver if IDE is modular (somebody added this in 2.3.51) - clear 'hw_regs_t hw' allocated from stack - mark idepnp_init() with __init - use ide_std_init_ports() instead of ide_setup_ports() Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@elka.pw.edu.pl> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

From: Geert Uytterhoeven <geert@linux-m68k.org> The IDE sparse fixups cause 2 warnings (unused variables `val' and `reg') on m68k and APUS. However, the reason why this code was commented out is gone. So just remove the special case.
