| |
Hi,
Here's a few patches that go on top of the previously posted series:
https://lkml.kernel.org/r/20210211173044.141215027@infradead.org https://lkml.kernel.org/r/20210218165938.213678824@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...
