4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wang Nan <wangnan0@huawei.com>
commit 44df1afdb174fd6038e419f80efd914c0b5f2f85 upstream.
Fix a compile error:
... CC util/libunwind/x86_32.o In file included from util/libunwind/x86_32.c:33:0: util/libunwind/../../arch/x86/util/unwind-libunwind.c: In function 'libunwind__x86_reg_id': util/libunwind/../../arch/x86/util/unwind-libunwind.c:110:11: error: 'EINVAL' undeclared (first use in this function) return -EINVAL; ^ util/libunwind/../../arch/x86/util/unwind-libunwind.c:110:11: note: each undeclared identifier is reported only once for each function it appears in mv: cannot stat 'util/libunwind/.x86_32.o.tmp': No such file or directory make[4]: *** [util/libunwind/x86_32.o] Error 1 make[3]: *** [util] Error 2 make[2]: *** [libperf-in.o] Error 2 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2
It happens when libunwind-x86 feature is detected.
