Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
produced these warnings:

In file included from arch/x86/vdso/vdso2c.c:161:0:
arch/x86/vdso/vdso2c.c: In function 'main':
arch/x86/vdso/vdso2c.h:118:6: warning: assuming signed overflow does not occur when assuming that (X + c) < X is always false [-Wstrict-overflow]
In file included from arch/x86/vdso/vdso2c.c:165:0:
arch/x86/vdso/vdso2c.h:118:6: warning: assuming signed overflow does not occur when assuming that (X + c) < X is always false [-Wstrict-overflow]

Probably introduced by commit e6577a7ce99a ("x86, vdso: Move the vvar
area before the vdso text").

Cheers,
