[PATCH 0/3] Handle delay slot for extable lookup

[Jiaxun Yang]

Hi all,

This series fixed extable handling for architecture delay slot (MIPS).

Please see previous discussions at [1].

There are some other places in kernel not handling delay slots properly,
such as uprobe and kgdb, I'll sort them later.

Thanks!
