      [ACPI] add boot parameters "acpi_osi=" and "acpi_serialize" · fea5b72f
      Len Brown authored
        acpi_osi= will disable the _OSI method -- which by default
      	tells the BIOS to behave as if Windows is the OS.
        acpi_serialize is for debugging AE_ALREADY_EXISTS failures

      [ACPI] ACPICA 20040311 from Bob Moore · 954c9189

      Fixed a problem where errors occurring during the parse phase of control
      method execution did not abort cleanly.  For example, objects created
      and installed in the namespace were not deleted.  This caused all
      subsequent invocations of the method to return the AE_ALREADY_EXISTS
      exception.
      
      Implemented a mechanism to force a control method to "Serialized"
      execution if the method attempts to create namespace objects.
      (The root of the AE_ALREADY_EXISTS problem.)
      
      Implemented support for the predefined _OSI "internal" control method.
      Initial supported strings are "Linux", "Windows 2000", "Windows 2001",
      and "Windows 2001.1", and can be easily upgraded for new strings as
      necessary.  This feature allows Linux to execute
      the fully tested, "Windows" code path through the ASL code
      
      Global Lock Support:  Now allows multiple acquires and releases with any
      internal thread.  Removed concept of "owning thread" for this special
      mutex.
      
      Fixed two functions that were inappropriately declaring large objects on
      the CPU stack: ps_parse_loop() and ns_evaluate_relative().
      Reduces the stack usage during method execution considerably.
      
      Fixed a problem in the ACPI 2.0 FACS descriptor (actbl2.h) where the
      S4Bios_f field was incorrectly defined as UINT32 instead of UINT32_BIT.
      
      Fixed a problem where acpi_ev_gpe_detect() would fault
      if there were no GPEs defined on the machine.
      
      Implemented two runtime options:  One to force all control method
      execution to "Serialized" to mimic Windows behavior, another to disable
      _OSI support if it causes problems on a given machine.
