From 7702a9c2856794b6bf961b408eba3bacb753bd5b Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 27 Oct 2025 09:44:40 +0100 Subject: entry: Inline irqentry_enter/exit_from/to_user_mode() There is no point to have this as a function which just inlines enter_from_user_mode(). The function call overhead is larger than the function itself.
