Subject: [PATCH 0/3] xtensa: fix {get,put}_user() for 64bit values

Hello,

this series fixes return value, out-of-bound stack access and value
truncation in xtensa implementation of {get,put}_user() for 64bit
values. It also cleans up naming of assembly parameters in
__{get,put}_user_asm and __check_align_{1,2,4}.

Al Viro (1):
  xtensa: fix {get,put}_user() for 64bit values

Max Filippov (2):
  xtensa: clean up assembly arguments in uaccess macros
  xtensa: fix type conversion in __get_user_[no]check
