[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Patrik Jakobsson <patrik.r.jakobsson@xxxxxxxxx>

commit 0a97c81a9717431e6c57ea845b59c3c345edce67 upstream.

Hook up drm_compat_ioctl to support 32-bit userspace on 64-bit kernels.
It turns out that N2600 and N2800 comes with 64-bit enabled. We
previously assumed there where no such systems out there.
