From 8313524a0d466f451a62709aaedf988d8257b21c Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Tue, 3 Oct 2006 00:00:00 -0400 Subject: ACPI: ACPICA 20060310 Tagged all external interfaces to the subsystem with the new ACPI_EXPORT_SYMBOL macro. This macro can be defined as necessary to assist kernel integration. For Linux, the macro resolves to the EXPORT_SYMBOL macro. The default definition is NULL. Added the ACPI_THREAD_ID type for the return value from acpi_os_get_thread_id(). This allows the host to define this as necessary to simplify kernel integration. The default definition is ACPI_NATIVE_UINT. Valery Podrezov fixed two interpreter problems related to error processing, the deletion of objects, and placing invalid pointers onto the internal operator result stack. http://bugzilla.kernel.org/show_bug.cgi?id=6028 http://bugzilla.kernel.org/show_bug.cgi?id=6151 Increased the reference count threshold where a warning is emitted for large reference counts in order to eliminate unnecessary warnings on systems with large namespaces (especially 64-bit.) Increased the value from 0x400 to 0x800. Due to universal disagreement as to the meaning of the 'c' in the calloc() function, the ACPI_MEM_CALLOCATE macro has been renamed to ACPI_ALLOCATE_ZEROED so that the purpose of the interface is 'clear'. ACPI_MEM_ALLOCATE and ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and ACPI_FREE.
