-Subject: [PATCH 076/103] x86/retpoline: Remove compile time warning
-commit b8b9ce4b5aec8de9e23cabb0a26b78641f9ab1d6 upstream.
-Remove the compile time warning when CONFIG_RETPOLINE=y and the compiler
-does not have retpoline support. Linus rationale for this is:
- It's wrong because it will just make people turn off RETPOLINE, and the
- asm updates - and return stack clearing - that are independent of the
- compiler are likely the most important parts because they are likely the
- ones easiest to target.
- And it's annoying because most people won't be able to do anything about
- it. The number of people building their own compiler? Very small. So if
- their distro hasn't got a compiler yet (and pretty much nobody does), the
- warning is just annoying crap.
- It is already properly reported as part of the sysfs interface. The
- compile-time warning only encourages bad things.
-Fixes: 76b043848fd2 ("x86/retpoline: Add initial retpoline support")
