+Subject: [PATCH] give up on gcc ilog2() constant optimizations
+
+commit 474c90156c8dcc2fa815e6716cc9394d7930cb9c upstream.
+
+gcc-7 has an "optimization" pass that completely screws up, and
+generates the code expansion for the (impossible) case of calling
+ilog2() with a zero constant, even when the code gcc compiles does not
+actually have a zero constant.
+
+And we try to generate a compile-time error for anybody doing ilog2() on
+a constant where that doesn't make sense (be it zero or negative).  So
+now gcc7 will fail the build due to our sanity checking, because it
+created that constant-zero case that didn't actually exist in the source
+code.
+
+There's a whole long discussion on the kernel mailing about how to work
+around this gcc bug.  The gcc people themselevs have discussed their
+"feature" in
+
+   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=72785
+
+but it's all water under the bridge, because while it looked at one
+point like it would be solved by the time gcc7 was released, that was
+not to be.
+
+So now we have to deal with this compiler braindamage.
+
+And the only simple approach seems to be to just delete the code that
+tries to warn about bad uses of ilog2().
+
+So now "ilog2()" will just return 0 not just for the value 1, but for
+any non-positive value too.
+
+It's not like I can recall anybody having ever actually tried to use
+this function on any invalid value, but maybe the sanity check just
+meant that such code never made it out in public.

+Subject: [PATCH] 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.
