The filename of the patch is: tools-objtool-makefile-don-t-assume-sync-check.sh-is-executable.patch and it can be found in the queue-4.14 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

commit 0f908ccbeca99ddf0ad60afa710e72aded4a5ea7 upstream.
patch(1) loses the x bit. So if a user follows our patching instructions in Documentation/admin-guide/README.rst, their kernel will not compile.

I'm curious. 3bd51c5a371de wasn't marked for any -stable so why is its fix being merged?
Because that commit is in the 4.14.10 release as part of the whole PTI mess. Distros like Gentoo that package the kernel as a patch on top of a clean tree break when trying to build the kernel without this commit.
thanks,
