Hi, Here's a few patches that go on top of the previously posted series:
https://lkml.kernel.org/r/20210211173044.141215...@infradead.org https://lkml.kernel.org/r/20210218165938.213678...@infradead.org and can also be found, in full, here: git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git objtool/wip The purpose is to replace every compiler generated (tail) call to the retpoline thunks with an alternative, one that avoids the thunk when retpolines are disabled. Very lightly tested...
