Subject: [PATCH 0/3] xtensa: fix {get,put}_user() for 64bit values
Date: Fri, 11 Oct 2019 17:07:08 -0700 [thread overview]
Message-ID: <20191012000711.3775-1-jcmvbkbc@gmail.com> (raw)
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}.

xtensa: clean up assembly arguments in uaccess macros
xtensa: fix type conversion in __get_user_[no]check
