Hi Adam, Thanks, this is looking good. powerpc will be able to use the generic header.

Well you can't use asm/arch_hweight.h in a generic header of course. I would suggest just including linux/ variants where practical for the asm-generic/asm-prototypes.h header. We should probably just bring all these arch patches through the kbuild tree. I'm sorry for the breakage: I didn't realize it broke the build with some configs, otherwise I would have given Michal a heads up before his pull request, and worked to get this stuff in first.

Yeah this seems to be the issue, it apparently slipped past all the automated builds. It seems like the existing CRC warnings in the tree only trigger in rare circumstances too, so something could be a bit fragile there.

I upgraded from 4.8 to 4.9-rc2 and noticed that kernel modules fail to load (log below). After investigating for some time I found this thread and apparently this is not still fixed, at least not in Linus' tree. Reverting 784d5699eddc5 fixed the issue for me. As I don't see any fix available (please correct me if I'm wrong) we should just revert that commit until it's properly fixed. Also note that there's a related fix from Steven: [PATCH] x86: Fix export for mcount and __fentry__ https://marc.info/?l=linux-kernel&m=147733572502413 For compiling the kernel I'm using Ubuntu 12.04: ii binutils 2.22-6ubuntu1.4 GNU assembler, linker and binary utilities ii gcc 4:4.6.3-1ubuntu5 GNU C compiler The kernel is running on a separate machine with Ubuntu 14.04.

With these two patches (on top of ath-201610251249 from ath.git, in practice 4.9-rc2 + latest wireless patches) module loading works again.

I'm pretty sure modules are correctly installed as I have used the same procedure for years: on my workstation I do 'make bindeb-pkg', copy the .deb to the test laptop and install the deb there. Also once I revert 784d5699eddc5 it starts immeadiately working.

I added this report to the list of regressions for Linux 4.9. I'll watch this thread for further updates on this issue to document progress in my weekly reports. Please let me know via regressions@leemhuis.info in case the discussion moves to a different place (bugzilla or another mail thread for example).

I believe inclusion of <linux/bitops.h> is the right thing to do, but if not, the patch would also need: extern unsigned int __sw_hweight8(unsigned int w); extern unsigned int __sw_hweight16(unsigned int w); extern unsigned int __sw_hweight32(unsigned int w); extern unsigned long __sw_hweight64(__u64 w); There's also the issue of mcount/__fentry__, but that's apparently already dealt with in 5de0a8c, already in mainline. > are you submitting a new version of your x86 asm-prototypes.h patch? The update is trivial, but yeah, I can resubmit. If I'm wrong about where __sw_hweight{8,16,32,64} should come from, please say so. Meow!
