Hi,
Could you please cherry-pick the following upstream commit into the
active stable trees?
Commit: 81cc73be40c6f028f1ee3f438ace46afe666dbae
Title: fbdev: core: Fix pointer desynchronization in fb_io_read()
It fixes a deterministic out-of-bounds (OOB) hardware read caused by
a pointer desynchronization when copy_to_user() performs a partial
copy. The commit has been merged upstream and contains the Cc: stable
tag, but it seems to have missed the recent stable queues.
Thanks,
Mingyu Wang

This just landed in a -rc kernel, please give us a chance to catch up
given that the load on stable kernels now has exploded.
It is now queued up.
