Subject: [PATCH v2 0/2] fix missing handling of __user in nommu's uaccess()
Date: Fri, 29 May 2020 21:02:16 +0200	[thread overview]
Message-ID: <20200529190218.36560-1-luc.vanoostenryck@gmail.com> (raw)

I received a bug report for an unrelated patch when used with m68k-nommu.
It appears that the origin of the problem is that __get_user() and
__put_user() doesn't handle correctly __user. These 2 patches fix this.

Note: this is only minimaly tested but is quite straightforward and
      since this only change __user annotation it will not change the
      generated code.


Changes since v1:
* fix typo: s/plan/plain/
* appease checkpatch with better style: s/__force*/__force */
* avoid excessive line length caused by the added cast.

Luc Van Oostenryck (2):
  m68k,nommu: add missing __user in uaccess' __ptr() macro
  m68k,nommu: fix implicit cast from __user in __{get,put}_user_asm()
