+To: Martin Schwidefsky <schwidefsky@de.ibm.com>
+To: Heiko Carstens <heiko.carstens@de.ibm.com>
+Cc: linux-s390@vger.kernel.org
+Cc: linux-kernel@vger.kernel.org
+
+There's a build failure with gcc9:
+
+ ./arch/s390/include/asm/jump_label.h: Assembler messages:
+ ./arch/s390/include/asm/jump_label.h:23: Error: bad expression
+ ./arch/s390/include/asm/jump_label.h:23: Error: junk at end of line, first unrecognized character is `r'
+ make[1]: *** [scripts/Makefile.build:277: init/main.o] Error 1
+
+According to the toolchain people, the actual issue is the use of
+"X" constraint which is too permissive. Switch to using "i" instead.

-We need to handle mmc_of_parse() errors during probe.

-This finally fixes the wifi regression on Raspberry Pi 3 series.
-In error case the wifi chip was permanently in reset because of
-the power sequence depending on the deferred probe of the GPIO expander.

+Subject: [PATCH] include/linux/module.h: mark init/cleanup_module aliases as
+ __cold
+Message-ID: <20190123173707.GA16603@gmail.com>
+MIME-Version: 1.0

+
+The upcoming GCC 9 release adds the -Wmissing-attributes warnings
+(enabled by -Wall), which trigger for all the init/cleanup_module
+aliases in the kernel (defined by the module_init/exit macros),
+ending up being very noisy.
+
+These aliases point to the __init/__exit functions of a module,
+which are defined as __cold (among other attributes). However,
+the aliases themselves do not have the __cold attribute.
+
+Since the compiler behaves differently when compiling a __cold
+function as well as when compiling paths leading to calls
+to __cold functions, the warning is trying to point out
+the possibly-forgotten attribute in the alias.
+
+In order to keep the warning enabled, we choose to silence
+the warning by marking the aliases as __cold. This is possible
+marking either the extern declaration, the definition, or both.
+In order to avoid changing the behavior of callers, we do it
+only in the definition of the aliases (since those are not
+seen by any other TU).
+
+Suggested-by: Martin Sebor <msebor@gcc.gnu.org>

+---
+Note that an alternative is using the new copy attribute
+introduced by GCC 9 (Martin told me about it, as well as the
+new warning).
+
+What I am concerned about using __copy is that I am not sure
+we should be copying all the attributes (even if some are
+blacklisted by the copy itself), since:
+  - We have unknown-to-GCC attributes (e.g. from plugins).
+  - We wouldn't enjoy the fix for older compilers
+    (e.g. if the fix had an actual impact).
+
+So here I took the conservative approach for the moment,
+and we can discuss/apply whether another solution is best.
+
+Jessica: please review what I explain in the commit message.
+Do we actually want the __cold attribute in the declaration
+as well? If yes, AFAIK, GCC would assume paths that end up
+calling the __init/__exit functions are not meant to be taken
+(but when we are asked to load modules, that is the expected
+path, no?).
+
+I will put this in the compiler-attributes tree and get
+some time in linux-next, unless you want to pick it up!

+
+The upcoming GCC 9 release extends the -Wmissing-attributes warnings
+(enabled by -Wall) to C and aliases: it warns when particular function
+attributes are missing in the aliases but not in their target.
+
+In particular, it triggers here because crc32_le_base/__crc32c_le_base
+aren't __pure while their target crc32_le/__crc32c_le are.
+
+These aliases are used by architectures as a fallback in accelerated
+versions of CRC32. See commit 9784d82db3eb ("lib/crc32: make core crc32()
+routines weak so they can be overridden").
+
+Therefore, being fallbacks, it is likely that even if the aliases
+were called from C, there wouldn't be any optimizations possible.
+Currently, the only user is arm64, which calls this from asm.
+
+Still, marking the aliases as __pure makes sense and is a good idea
+for documentation purposes and possible future optimizations,
+which also silences the warning.
+
+Signed-off-by: Miguel Ojeda <miguel.ojeda.sandonis@gmail.com>
+---
+I am picking this up through the compiler-attributes tree
+and putting it into -next along with the other cleanup
+for -Wmissing-attributes (unless some other maintainer wants it).
