Will Deacon 1142b71d85 ARM: 6489/1: thumb2: fix incorrect optimisation in usracc ... Commit 8b592783 added a Thumb-2 variant of usracc which, when it is called with \rept=2, calls usraccoff once with an offset of 0 and secondly with a hard-coded offset of 4 in order to avoid incrementing the pointer again. If \inc != 4 then we will store the data to the wrong offset from \ptr. Luckily, the only caller that passes \rept=2 to this function is __clear_user so we haven't been actively corrupting user data. This patch fixes usracc to pass \inc instead of #4 to usraccoff when it is called a second time.
