I don't think they are related to the thread_info changes except very incidentally. >From the errors ("expected ':' before '__stringify'") it looks like __stringify() isn't defined there, and I do think that header file should include to get it. I don't actually see how that merge commit you bisected to could possibly matter (the diff doesn't show any header file include changes, or any parisc ones), but I suspect you might have bisected to it because we did end up having actual thread_info errors on parsic that weren't fixed until commit 2a2e8202c7a1 ("parisc: move CPU field back into thread_info"). So I suspect the parisc build problems started with thread_info issues at that merge commit you pinpoint, and then by commit 2a2e8202c7a1 some other header file simplification had exposed that "no __stringify()" thing). Helge - apparently from allmodconfig and others, we have: arch/parisc/include/asm/jump_label.h: In function 'arch_static_branch': arch/parisc/include/asm/jump_label.h:18:18: error: expected ':' before '__stringify' and others, which does look like just a missing header file (that was presumably previously implicitly included earlier, and now the implicit include is gone).
