BugLink: https://bugs.launchpad.net/bugs/1819921 V2: Fix non-x86 building error. [Impact] Some lenovo laptops failed to boot at a very early stage, only blackscreen shown. [Fix] Some system BIOS set definition in if statement, it would be deferred to be loaded. Some devices would not work properly and cause a system lockup. add a quirk for these laptops to execute all acpi tables and make system work properly. [Test] Tested on several laptops, the laptop that failed to boot boots well. Other laptops still works fine. Build passed on arm arch. [Regression Potential] SAUCE patch. Low, specific change depends on hardware. Upstream fix: commit 5a8361f7ecceaed64b4064000d16cb703462be49 Author: Schmauss, Erik <erik.schmauss@intel.com> Date: Thu Feb 15 13:09:30 2018 -0800 ACPICA: Integrate package handling with module-level code Due to the lots of changes in this commit and other regressions concern So made a sauce patch in Bionic kernel with the specific BIOS series. Verified on several laptops. Fix boot failure and no regression found. The upstream fix is in 4.17-rc1, so only Bionic/OEM 4.15 kernels need it.
