Hi,
In doing my tests last night before sending out my patch series this
morning, I found that s390 build didn't work, but it wasn't due to my
patches. I removed all my patches and built with latest mainline (which
builds fine), and then merged the current tip/perf/core. The result
didn't build.
I kicked off a ktest git bisect with last night's Linus tree as good,
and with the merged in tip/perf/core as bad. It ended up with this patch
that broke the build (which looks like a likely suspect).
The break is this:
LD .tmp_vmlinux1
arch/s390/oprofile/built-in.o: In function `oprofile_arch_exit':
(.text+0x3f52): undefined reference to `oprofile_timer_exit'
make[1]: *** [.tmp_vmlinux1] Error 1
make: *** [sub-make] Error 2
The patch the bisect found that breaks the build is this:
commit 75c43a20b220f885c39ffa7cdbbb1191e257a9a9

oprofile: Remove exit function for timer mode
Remove exit functions by moving init/exit code to oprofile's setup/
shutdown functions. Doing so the oprofile module exit code will be
easier and less error-prone.
