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 29183a70b0b828500816bd794b3fe192fce89f73 ("ntp: Fixup adjtimex freq validation on 32-bit systems"). If you haven't already done this, please consider applying the fix to the 3.12 series. Thank you!
