Josh Poimboeuf 3e70fa9005 objtool: Stop UNRET validation on UD2
[ Upstream commit 9f9cc012c2 ]

In preparation for simplifying INSN_SYSCALL, make validate_unret()
terminate control flow on UD2 just like validate_branch() already does.

README

Linux kernel

There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first.

In order to build the documentation, use make htmldocs or make pdfdocs. The formatted documentation can also be read online at:

https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
