+Subject: ARM: fix put_user() for gcc-8
+
+Building kernels before linux-4.7 with gcc-8 results in many build failures
+when gcc triggers a check that was meant to catch broken compilers:
+
+/tmp/ccCGMQmS.s:648: Error: .err encountered
+
+According to the discussion in the gcc bugzilla, a local "register
+asm()" variable is still supposed to be the correct way to force an
+inline assembly to use a particular register, but marking it 'const'
+lets the compiler do optimizations that break that, i.e the compiler is
+free to treat the variable as either 'const' or 'register' in that case.
+
+Upstream commit 9f73bd8bb445 ("ARM: uaccess: remove put_user() code
+duplication") fixed this problem in linux-4.8 as part of a larger change,
+but seems a little too big to be backported to 4.4.
+
+Let's take the simplest fix and change only the one broken line in the
+same way as newer kernels.
