      ACPI: ACPICA 20060623 · 967440e3
      由 Bob Moore 提交于 
      Implemented a new acpi_spinlock type for the OSL lock
interfaces.  This allows the type to be customized to
the host OS for improved efficiency (since a spinlock is
usually a very small object.)

Implemented support for "ignored" bits in the ACPI
registers.  According to the ACPI specification, these
bits should be preserved when writing the registers via
a read/modify/write cycle. There are 3 bits preserved
in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9],
and PM1_STATUS[11].
http://bugzilla.kernel.org/show_bug.cgi?id=3691

Implemented the initial deployment of new OSL mutex
interfaces.  Since some host operating systems have
separate mutex and semaphore objects, this feature was
requested. The base code now uses mutexes (and the new
mutex interfaces) wherever a binary semaphore was used
previously. However, for the current release, the mutex
interfaces are defined as macros to map them to the
existing semaphore interfaces.

Fixed several problems with the support for the control
method SyncLevel parameter. The SyncLevel now works
according to the ACPI specification and in concert with the
Mutex SyncLevel parameter, since the current SyncLevel is
a property of the executing thread. Mutual exclusion for
control methods is now implemented with a mutex instead
of a semaphore.

Fixed three instances of the use of the C shift operator
in the bitfield support code (exfldio.c) to avoid the use
of a shift value larger than the target data width. The
behavior of C compilers is undefined in this case and can
cause unpredictable results, and therefore the case must
be detected and avoided.  (Fiodor Suietov)

Added an info message whenever an SSDT or OEM table
is loaded dynamically via the Load() or LoadTable()
ASL operators. This should improve debugging capability
since it will show exactly what tables have been loaded
(beyond the tables present in the RSDT/XSDT.)

      ACPIPHP: prevent duplicate slot numbers when no _SUN · 95b38b3f
      由 Kristen Accardi 提交于 
      Dock bridges generally do not implement _SUN, yet show up as ejectable
slots.  If you have more than one ejectable slot that does not implement
SUN, with the current code you will get duplicate slot numbers.  So, if
there is no _SUN, use the current count of the number of slots found
instead.

      ACPIPHP: use ACPI dock driver · 4e8662bb
      由 Kristen Accardi 提交于 
      Modify the acpiphp driver to use the ACPI dock driver for dock
notifications.  Only load the acpiphp driver if we find we have pci dock
devices.

      ACPI: dock driver · a5e1b940
      由 Kristen Accardi 提交于 
      Create a driver which lives in the acpi subsystem to handle dock events.
This driver is not an "ACPI" driver, because acpi drivers require that the
object be present when the driver is loaded.
