From 52fc0b026e99b5d5d585095148d997d5634bbc25 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Mon, 2 Oct 2006 00:00:00 -0400 Subject: [ACPI] ACPICA 20060210 Removed a couple of extraneous ACPI_ERROR messages that appeared during normal execution. These became apparent after the conversion from ACPI_DEBUG_PRINT. Fixed a problem where the CreateField operator could hang if the BitIndex or NumBits parameter referred to a named object. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5359 Fixed a problem where a DeRefOf operation on a buffer object incorrectly failed with an exception. This also fixes a couple of related RefOf and DeRefOf issues. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5360 http://bugzilla.kernel.org/show_bug.cgi?id=5387 http://bugzilla.kernel.org/show_bug.cgi?id=5392 Fixed a problem where the AE_BUFFER_LIMIT exception was returned instead of AE_STRING_LIMIT on an out-of-bounds Index() operation. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5480 Implemented a memory cleanup at the end of the execution of each iteration of an AML While() loop, preventing the accumulation of outstanding objects. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5427 Eliminated a chunk of duplicate code in the object resolution code. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5336 Fixed several warnings during the 64-bit code generation.
