Subject: ACPI: add missing _OSI strings
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=aa165971c2923d05988f920c978e438dbc7b0de6;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ACPI: add missing _OSI strings

Linux supports some optional features, but it should notify the BIOS about
them via the _OSI method.  Currently Linux doesn't notify any, which might
make such features not work because the BIOS doesn't know about them.

Jarosz has a system which needs this to make ACPI processor aggregator
device work.
