 ----------------------------------------
+25 March 2014. Summary of changes for version 20140325:
+
+1) ACPICA kernel-resident subsystem:
+
+Updated the auto-serialize feature for control methods. This feature 
+automatically serializes all methods that create named objects in order 
+to prevent runtime errors. The update adds support to ignore the 
+currently executing AML SyncLevel when invoking such a method, in order 
+to prevent disruption of any existing SyncLevel priorities that may exist 
+in the AML code. Although the use of SyncLevels is relatively rare, this 
+change fixes a regression where an AE_AML_MUTEX_ORDER exception can 
+appear on some machines starting with the 20140214 release.
+
+Added a new external interface to allow the host to install ACPI tables 
+very early, before the namespace is even created. AcpiInstallTable gives 
+the host additional flexibility for ACPI table management. Tables can be 
+installed directly by the host as if they had originally appeared in the 
+XSDT/RSDT. Installed tables can be SSDTs or other ACPI data tables 
+(anything except the DSDT and FACS). Adds a new file, tbdata.c, along 
+with additional internal restructuring and cleanup. See the ACPICA 
+Reference for interface details. Lv Zheng.
+
+Added validation of the checksum for all incoming dynamically loaded 
+tables (via external interfaces or via AML Load/LoadTable operators). Lv 
+Zheng.
+
+Updated the use of the AcpiOsWaitEventsComplete interface during Notify 
+and GPE handler removal. Restructured calls to eliminate possible race 
+conditions. Lv Zheng.
+
+Added a warning for the use/execution of the ASL/AML Unload (table) 
+operator. This will help detect and identify machines that use this 
+operator if and when it is ever used. This operator has never been seen 
+in the field and the usage model and possible side-effects of the drastic 
+runtime action of a full table removal are unknown.
+
+Reverted the use of #pragma push/pop which was introduced in the 20140214 
+release. It appears that push and pop are not implemented by enough 
+compilers to make the use of this feature feasible for ACPICA at this 
+time. However, these operators may be deployed in a future ACPICA 
+release.
+
+Added the missing EXPORT_SYMBOL macros for the install and remove SCI 
+handler interfaces.
+
+Source code generation:
+1) Disabled the use of the "strchr" macro for the gcc-specific 
+generation. For some versions of gcc, this macro can periodically expose 
+a compiler bug which in turn causes compile-time error(s).
+2) Added support for PPC64 compilation. Colin Ian King.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and 
+has a much larger code and data size.
+
+  Current Release:
+    Non-Debug Version:  97.0K Code, 27.2K Data, 124.2K Total
+    Debug Version:     189.7K Code, 79.5K Data, 269.2K Total
+  Previous Release:
+    Non-Debug Version:  96.5K Code, 27.2K Data, 123.7K Total
+    Debug Version:     188.6K Code, 79.0K Data, 267.6K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Disassembler: Added several new features to improve the readability of 
+the resulting ASL code. Extra information is emitted within comment 
+fields in the ASL code:
+1) Known _HID/_CID values are decoded to descriptive text.
+2) Standard values for the Notify() operator are decoded to descriptive 
+text.
+3) Target operands are expanded to full pathnames (in a comment) when 
+possible.
+
+Disassembler: Miscellaneous updates for extern() handling:
+1) Abort compiler if file specified by -fe option does not exist.
+2) Silence unnecessary warnings about argument count mismatches.
+3) Update warning messages concerning unresolved method externals.
+4) Emit "UnknownObj" keyword for externals whose type cannot be 
+determined.
+
+AcpiHelp utility:
+1) Added the -a option to display both the ASL syntax and the AML 
+encoding for an input ASL operator. This effectively displays all known 
+information about an ASL operator with one AcpiHelp invocation.
+2) Added substring match support (similar to a wildcard) for the -i 
+(_HID/PNP IDs) option.
+
+iASL/Disassembler: Since this tool does not yet support execution on big-
+endian machines, added detection of endianness and an error message if 
+execution is attempted on big-endian. Support for big-endian within iASL 
+is a feature that is on the ACPICA to-be-done list.
+
+AcpiBin utility:
+1) Remove option to extract binary files from an acpidump; this function 
+is made obsolete by the AcpiXtract utility.
+2) General cleanup of open files and allocated buffers.
