The original code was lost accidently, it was not generated along with the following commit of mechanism improvements and thus not get merged: Commit: d5a36100 Subject: ACPICA: Add mechanism for early object repairs on a per-name basis Adds the framework to allow object repairs very early in the return object analysis. Enables repairs like string->unicode, etc. This patch restores the implementation of the NULL element repair code for ACPI_RTYPE_NONE. In the original design, ACPI_RTYPE_NONE is defined to collect simple NULL object repairs. Lv Zheng.

Use push and pop to both guarantee that the correct alignment is used, and to restore the alignment to whatever it was before the header was included. It is reported that the #pragma pack(push/pop) directives are not supported by the specific GCCs, but this patch still doesn't affect kernel build as there are already #pragma pack([1]) directives used in the old ACPICA headers, which means there shouldn't be GCCs that are currently used to compile the ACPI kernels do not support #pragma pack() directives.

Sometimes, there might be bugs caused by unexpected AML which is compliant to the Windows but not compliant to the Linux implementation. There is a predefined validation mechanism implemented in ACPICA to repair the unexpected AML evaluation results that are caused by the unexpected AMLs. For example, BIOS may return misorder _CST result and the repair mechanism can make an ascending order on the returned _CST package object based on the C-state type. This mechanism is quite useful to implement an AML interpreter with better compliance with the real world where Windows is the de-facto standard and BIOS codes are only tested on one platform thus not compliant to the ACPI specification. But if a compliance issue hasn't been figured out yet, it will be difficult for developers to identify if the unexpected evaluation result is caused by this mechanism or by the AML interpreter. For example, _PR0 is expected to be a control method, but BIOS may use Package: "Name(_PR0, Package(1) {P1PR})". This boot option can disable the predefined validation mechanism so that developers can make sure the root cause comes from the parser/executer. This patch adds a new kernel parameter to disable this feature. A build test has been made on a Dell Inspiron mini 1100 (i386 z530) machine when this patch is applied and the corresponding boot test is performed w/ or w/o the new kernel parameter specified.

They will be optimized out during link stage for normal builds.

The utility has the capability to load some various tables to test features of ACPICA. However, there are enough of them that the output of the utility became confusing. With this change, only the required local tables are displayed (RSDP, XSDT, etc.) along with the actual tables loaded via the command line specification. This makes the default output simler and easier to understand. The -el command line option restores the original behavior for testing purposes.

Commit c420619d "pinctrl: pinconf: remove checks on ops->pin_config_get" removed the check on (ops != NULL) when performing pinconf_pins_show() or pinconf_groups_show(). As these entries are always enabled, even if pinconf is not supported, reading will result in an oops due to NULL ops. Instead of checking for ops, remove the corresponding debugfs entries if pinconf and/or pinmux are not implemented. Tested on OMAP3 (pinctrl-single).

When a context is first referenced in the command stream, make sure that all scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that all bound resources are put on the resource validate list. This is needed for legacy emulation, since legacy user-space drivers will typically not re-emit shader bindings.
