Heiko Carstens 45a9877d6c s390/uaccess: add missing earlyclobber annotations to __clear_user()
commit 89aba4c26fae4e459f755a18912845c348ee48f3 upstream.

Add missing earlyclobber annotation to size, to, and tmp2 operands of the
__clear_user() inline assembly since they are modified or written to before
the last usage of all input operands. This can lead to incorrect register
allocation for the inline assembly.

Fixes: 6c2a9e6df6 ("[S390] Use alternative user-copy operations for new hardware.")
