	On 32-bit x86 when building with clang-9, the 'division' loop gets turned back into an inefficient division that causes a link error: kernel/time/vsyscall.o: In function `update_vsyscall': vsyscall.c:(.text+0xe3): undefined reference to `__udivdi3' Use the existing __iter_div_u64_rem() function which is used to address the same issue in other places.

2019-06-22	timekeeping: Provide a generic update_vsyscall() implementation	Vincenzo Frascino
	The new generic VDSO library allows to unify the update_vsyscall[_tz]() implementations. Provide a generic implementation based on the x86 code and the bindings which need to be implemented in architecture specific code. [ tglx: Moved it into kernel/time where it belongs. Removed the pointless line breaks in the stub functions.
