Subject: objtool: Add vpanic() to the noreturn list
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=90a01bdcbd01513d6b7f79a98a03daf2c7b5ccde;p=thirdparty%2Flinux.git

objtool: Add vpanic() to the noreturn list

vpanic() does not return. However, objtool doesn't know this and gets
confused:
kernel/trace/rv/reactor_panic.o: warning: objtool: rv_panic_reaction(): unexpected end of section .text

Add vpanic() to the list of noreturn functions.
