[PATCH v5 1/5] ACPICA: Tables: Fix "UNLOAD" code path lock issues

ACPICA commit 39227380f5b99c51b897a3ffedd88508aa26789b The previous lock fixes didn't cover "Unload" opcode and table unload APIs, this patch fixes lock issues in the "Unload" code path. BZ 1325, Lv Zheng. Link: https://github.com/acpica/acpica/commit/39227380 Link:

[PATCH v5 0/5] ACPI 2.0: Stop defer-executing module level code

After fixing ACPICA internal locking issues, we can enable the correct grammar support for the table loading. The new grammar treats the entire table as TermList rather than ObjectList, thus the module level code should be executed right in place. MLC (module level code) is an ACPICA terminology

[PATCH v5 2/5] ACPICA: Parser: Fix a regression in LoadTable support

ACPICA commit a78506e0ce8ab1d20db2a055d99cf9143e89eb29 LoadTable allows an alternative RootPathString than the default "\", while the new table execution support fails to keep this logic. This regression can be detected by ASLTS - TLT0.tst4, this patch fixes this regression. Linux upstream is

[PATCH v5 3/5] ACPI 2.0 / AML: Enable correct ACPI subsystem initialization order for new table loading mode

This patch enables the following initialization order for the new table loading mode (which is enabled by setting acpi_gbl_parse_table_as_term_list to TRUE): 1. Install default region handlers (SystemMemory, SystemIo, PciConfig, EmbeddedControl via ECDT) without evaluating _REG; 2. Load

[PATCH v5 5/5] ACPI 2.0 / AML: Fix module level execution by correctly parsing table as TermList

This experiment follows de-facto standard behavior, parsing entire table as a single TermList, so that all module level executions are possible during the table loading. If regressions are found against the enabling of this experimental fix, this patch is the only one that should get bisected
