AUR package for building linux with the patch that fix BIOS bug https://bugzilla.kernel.org/show_bug.cgi?id=213579
Note that this is needed only to those that are affected by this BIOS bug and are unable to upgrade the firmware
Optionally change the config file
If you changed/added any file you have to regenerate the checksums with
$ updpkgsums
If you want to use parallel compilation you have to export the env variable $MAKEFLAGS.
Change the number according to the available processors. To find out how many there are run nproc
$ export MAKEFLAGS="-j8"
To build and install the packages just run
$ makepkg -s
$ pacman -U linux-custom-*
