I broke Emacs mouse support on the console
I accidentally broke Emacs mouse support on the Linux console. o_O
The TIOCLINUX patch for disabling dangerous IOCTLs for the Linux console driver (background discussed on the Wiki) ended up accidentally making the mouse cursor invisible on the Linux console (the proper text mode one, not xterm).
I apologize for breaking this. We luckily found a patch for it and it is now rolling out to stable Linux kernels.
If your mouse does not work as expected in Emacs on the Linux console, please update your kernel to a newer release.
It boggles me that this managed to slip through the cracks in the initial review, after we had done such an exhaustive search for remaining users in Debian code search. Lesson learned.
