Hi, I believe that the following packages should be removed: linux-mainline-ux31e [1] -- last updated in early 2012, orphaned, only three votes. broadcom-wl-mainline [2] -- last updated in late 2012, orphaned, zero votes, source gone, and apparently doesn't build anyway. There's a third package which appears to be semi-active: linux-mainline-dellxps [3], I've asked the maintainer whether the package still has any point, as she/he has said that the linux-mainline package works fine for them, so it may be worth keeping an eye on the comments. Cheers, WorMzy [1] https://aur.archlinux.org/packages/linux-mainline-ux31e/ [2] https://aur.archlinux.org/packages/broadcom-wl-mainline/ [3] https://aur.archlinux.org/packages/linux-mainline-dellxps/
