Bug Description

There was a regression in intel mesa driver that caused raise of SIGFPE signal which resulted in startup error messages (about division by zero or invalid floating point operation) in some applications and games sensitive to this behavior.

Currently it resolved in upstream:
https://bugs.freedesktop.org/show_bug.cgi?id=95419
By following commit:
https://cgit.freedesktop.org/mesa/mesa/commit/?id=01c89ccc5d1529aa1efbae80c8ef641a59abbd93
Is it possible to include foregoing patch to avoid bug in current distributions?

Distribution: Ubuntu 16.04
Video card: Intel HD 4600
Mesa version: 11.2.0-1ubuntu2.2

Should not it be backported to 16.04 since it's LTS and it is requires only trivial patch?
