From 51ae253870f55e14ba2854ce9577ac2920efef0c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 15 Sep 2017 21:29:13 +0200 Subject: [PATCH] xen: x86: mark xen_find_pt_base as __init gcc-4.6 causes a harmless link-time warning: WARNING: vmlinux.o(.text.unlikely+0x48e): Section mismatch in reference from the function xen_find_pt_base() to the function .init.text:m2p() The function xen_find_pt_base() references the function __init m2p(). This is often because xen_find_pt_base lacks a __init annotation or the annotation of m2p is wrong. Newer compilers inline this function, so it never shows up, but marking it __init is the right way to avoid the warning.
