x86:64:allnoconfig still fails to build.

To reproduce:
  make ARCH=x86_64 allnoconfig
  make ARCH=x86_64 arch/x86/entry/vdso/vma.o

arch/x86/entry/vdso/vma.c: In function ‘map_vdso’:
arch/x86/entry/vdso/vma.c:175:9: error:
	implicit declaration of function ‘pvclock_pvti_cpu0_va’

The function is declared in arch/x86/include/asm/pvclock.h, which is only 
indirectly included. For 32-bit allnoconfig builds, the include path is:
  arch/x86/entry/vdso/vma.c
    include/linux/mm.h
      ./arch/x86/include/asm/pgtable.h
        ./arch/x86/include/asm/pgtable_32.h

but pgtable_64.h doesn't include pgtable_32.h, and the declaration is
missing as result.

The include of asm/pvclock.h was added upstream with commit cc1e24fdb064d
("x86/vdso: Remove pvclock fixmap machinery") which applies cleanly to
v4.4.y. Please consider adding it, or at least add the missing include.

Thanks,
Guenter
