[ Upstream commit bff47c2302cc249bcd550b17067f8dddbd4b6f77 ]

When building with C=1, sparse issues a warning:

CHECK arch/x86/entry/vdso/vdso32-setup.c
arch/x86/entry/vdso/vdso32-setup.c:28:28: warning: symbol 'vdso32_enabled' was not declared. Should it be static?

Provide the missing header file.
