Without these patches, specifically the
0001-Do-not-assume-fixed-line-lengths-for-proc-acpi-wakeu.patch (wakeu
patch typo from upstream,) acpitool will consume 100% CPU when reading
long lines (>40 characters) like:
ADP1 S4 *disabled platform:ACPI0003:00
Some of these should be longDescriptions, but most others just
shouldn't contain newlines. E.g. write
description = "Bla";
and not
description = ''
Bla
'';
This pollutes "nix-env -qa --description" output.
