Hi,
This 3rd version of the series which fixes %p uses in kprobes.
Some by replacing with %pS, some by replacing with %px but
masking with kallsyms_show_value().
I've read the thread about %pK and if I understand correctly
we shouldn't print kernel addresses. However, kprobes debugfs
interface can not stop to show the actual probe address because
it should be compared with addresses in kallsyms for debugging.
So, it depends on that kallsyms_show_value() allows to show
address to user, because if it returns true, anyway that user
can dump /proc/kallsyms.
Other error messages are replaced it with %pS or just removed.
This series also including some fixes for arch ports too.
Changes in this version;
- [2/7]: Updated for the latest linus tree.
- [4/7][5/7]: Do not use %px.
Thank you,
