Hi all,
After merging the modules tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
kernel/trace/ftrace.c: In function 'ftrace_lookup_symbols':
kernel/trace/ftrace.c:8316:52: error: passing argument 1 of 'module_kallsyms_on_each_symbol' from incompatible pointer type [-Werror=incompatible-pointer-types]

Caused by commit
90de88426f3c ("livepatch: Improve the search performance of module_kallsyms_on_each_symbol()")
from the modules tree interatcing with commit
3640bf8584f4 ("ftrace: Add support to resolve module symbols in ftrace_lookup_symbols")
from the next-next tree.
I have no idea how to easily fix this up, so I have used the modules
tree from next-20221111 for today in the hope someone will send me a fix.
