From: Christophe Leroy Date: Tue, 22 Mar 2022 15:40:18 +0000 (+0100) Subject: powerpc/code-patching: Don't call is_vmalloc_or_module_addr() without CONFIG_MODULES X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cb3ac45214c03852430979a43180371a44b74596;p=linux.git powerpc/code-patching: Don't call is_vmalloc_or_module_addr() without CONFIG_MODULES If CONFIG_MODULES is not set, there is no point in checking whether text is in module area. This reduced the time needed to activate/deactivate ftrace by more than 10% on an 8xx.
