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.
A gentle ping :-) This series fixes a regression, perhaps it should go through fixes tree. Thanks - Jiaxun
