Sorry, I was imprecise. I was referring to the kernel's kallsyms tables produced by scripts/kallsyms.c. This patch left them in the the kallsyms tables and filtered them out from /proc/kallsyms.
Yes, but it isn't easy to do it by script/kallsyms.c , and IMO, it should be correct to hide them for user space but keep them in kallsyms table.
It's weird that cpu_v7_suspend_size appeared above, since kallsyms should filter out 'A' symbols already.
Sorry, the 'A' symbol is a mistake, but the others do exist in /proc/kallsyms. Thanks, -- Ming Lei
