Commit 8382c668ce4f ("x86/vdso: Add support for exception fixup in vDSO functions") added a printf of len which is size_t. Compilers now complain on 32b: In file included from arch/x86/entry/vdso/vdso2c.c:162: arch/x86/entry/vdso/vdso2c.h: In function 'extract64': arch/x86/entry/vdso/vdso2c.h:38:52: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'size_t' {aka 'unsigned int'}
So use proper modifier (%zu) for size_t.
