timekeeping: Another fix to the VSYSCALL_OLD update_vsyscall
Benjamin Herrenschmidt pointed out that I further missed modifying update_vsyscall after the wall_to_mono value was changed to a timespec64. This causes issues on powerpc32, which expects a 32bit timespec. This patch fixes the problem by properly converting from a timespec64 to a timespec before passing the value on to the arch-specific vsyscall logic. [ Thomas is currently on vacation, but reviewed it and wanted me to send this fix on to you directly. ] Cc: LKML <linux-kernel@vger.kernel.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Reported-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Reviewed-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: John Stultz <john.stultz@linaro.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
