Hello Jiri,
Commit f09c62a1c27dcc43a06e5ebb27ae67306146277b ("time: adjtimex:
Validate the ADJ_FREQUENCY values", appeared first in 3.12.37,
upstream is 5e5aeb4367b450a28f447f6d5ab57d8f2ab16a5f) breaks the
adjtimex call on 32 bit systems. This was fixed upstream by commit
29183a70b0b828500816bd794
[sent again with Rodolfo in the list of recipients, something went

Hi all,
This patch adds memory barriers to the lock-less circular buffer in the n_tty
driver to fix the race condition described in [1] and [2] for SMP machines.
The patch is based on the instructions in Documentation/circular-buffers.txt
nt read_head _after_ the data
is placed in the buffer and thus fixes the race for non-SMP machines.
To fix the problem for SMP machines, memory barriers must be added in
a separate patch.

Is there a datasheet/application note/technical note from Micron
describing this issue? Like the TN-13-07 for the other M29EW fixes?
Are all M29EW types affected?
Thanks,
