From 0680eb1f485ba5aac2ee02c9f0622239c9a4b16c Mon Sep 17 00:00:00 2001 From: John Stultz Date: Wed, 13 Aug 2014 12:47:14 -0700 Subject: [PATCH] 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 Cc: Thomas Gleixner Cc: Ingo Molnar Cc: Benjamin Herrenschmidt Reported-by: Benjamin Herrenschmidt Reviewed-by: Thomas Gleixner Signed-off-by: John Stultz Signed-off-by: Linus Torvalds --- kernel/time/timekeeping.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/kernel/time/timekeeping.c b/kernel/time/timekeeping.c index f36b02838a47..fb4a9c2cf8d9 100644 --- a/kernel/time/timekeeping.c +++ b/kernel/time/timekeeping.c @@ -338,10 +338,11 @@ EXPORT_SYMBOL_GPL(ktime_get_mono_fast_ns); static inline void update_vsyscall(struct timekeeper *tk) { - struct timespec xt; + struct timespec xt, wm; xt = timespec64_to_timespec(tk_xtime(tk)); - update_vsyscall_old(&xt, &tk->wall_to_monotonic, tk->tkr.clock, tk->tkr.mult, + wm = timespec64_to_timespec(tk->wall_to_monotonic); + update_vsyscall_old(&xt, &wm, tk->tkr.clock, tk->tkr.mult, tk->tkr.cycle_last); } -- 2.30.2
