      [ACPI] restore PCI Interrupt Link Devices upon resume · 06df8085
      Nathan Bryant authored 
      * register as as a sys_device so that we can get resume callbacks and restore
  interrupt routing state.
* add acpi_pci_link_resume(), which will be called when resuming from a suspend
  state that needs IRQ routing to be restored. This fixes issues reported on
  the mailing lists, e.g.:
http://marc.theaimsgroup.com/?l=acpi4linux&m=109142999328643&w=2
* rename setonboot --> initialized
* change to test acpi_noirq in init

We want to initialize everything on S3 resume in case the BIOS points an
interrupt link somewhere we didn't expect. (Doing so avoids "missing interrupt"
or "irq x: nobody cared" problems.) According to Len, past experience has shown
that it's a good idea to initialize only devices that exist or were explicitly
asked for, so we try to initialize only the IRQ's that were previously
initialized at some point before suspend, by checking the "initialized" flag.
This corresponds to links that have PCI devices attached.  Everything else, we
leave alone. Assuming the BIOS does the same thing on resume that it did on
boot, this will leave all the unused links in the same state that they were on
boot.

We are registered as a sysdev in order to do this work fairly early during
resume, before devices are resumed; some devices may not call
pci_device_enable.

Previous "setonboot once" behavior is left in place, to be conservative.

      Restructured the internal HW GPE interfaces to pass/track
the current state of interrupts (enabled/disabled) in
order to avoid possible deadlock and increase flexibility
of the interfaces.

Implemented a "lexicographical compare" for String and
Buffer objects within the logical operators -- LGreater,
LLess, LGreaterEqual, and LLessEqual -- as per further
clarification to the ACPI specification.  Behavior is
similar to C library "strcmp".

Completed a major reduction in CPU stack use for the
acpi_get_firmware_table external function.  In the 32-bit
non-debug case, the stack use has been reduced from 168
bytes to 32 bytes.

Deployed a new run-time configuration flag,
acpi_gbl_enable_interpeter_slack, whose purpose is to allow
the AML interpreter to forgive certain bad AML constructs.
Default setting is FALSE.

Implemented the first use of acpi_gbl_enable_interpeter_slack
in the Field IO support code.  If enabled, it allows field
access to go beyond the end of a region definition if the
field is within the region length rounded up to the next
access width boundary (a common coding error.)

Renamed OSD_HANDLER to acpi_osd_handler, and
OSD_EXECUTION_CALLBACK to acpi_osd_exec_callback for
consistency with other ACPI symbols.  Also, these symbols
are lowercased by the latest version of the acpisrc tool.

The prototypes for the PCI interfaces in acpiosxf.h
have been updated to rename "register" to simply "reg"
to prevent certain compilers from complaining.

      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.

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.
