I ran into a 4.9 build regression in randconfig testing, starting with the KAISER patches:
arch/x86/mm/kaiser.c: In function 'kaiser_init': arch/x86/mm/kaiser.c:347:8: error: 'vsyscall_pgprot' undeclared (first use in this function); did you mean 'massage_pgprot'?
This is easy enough to fix, we just need to make the declaration visible outside of the #ifdef. This works because the code using it is optimized away when vsyscall_enabled() returns false at compile time.

Thanks for these, I'll queue them up in the next round after these kernels get released in a few days.
