This version is a rebase on top of latest Linus tree which includes the fix 8f2b468aadc ("s390/vtime: correct system time accounting").
Also a small change: I have moved account_system_index_scaled() to s390 in patch "s390/cputime: delayed accounting of system time" because it is the only user of the function. git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git vtime/acc-v2 Thanks, Frederic --- Frederic Weisbecker (9): powerpc32: Fix stale scaled stime on context switch ia64: Fix wrong start cputime assignment on task switch cputime: Allow accounting system time using cpustat index cputime: Export account_guest_time powerpc: Prepare accounting structure for cputime flush on tick powerpc: Migrate stolen_time field to accounting structure powerpc/vtime: Accumulate cputime and account only on tick/task switch ia64: Accumulate cputime and account only on tick/task switch vtime: Rename vtime_account_user() to vtime_flush() Martin Schwidefsky (1): s390/cputime: delayed accounting of system time arch/ia64/include/asm/thread_info.h | 6 ++ arch/ia64/kernel/time.c | 66 +++++++++++----- arch/powerpc/include/asm/accounting.h | 14 +++- arch/powerpc/include/asm/paca.h | 1 - arch/powerpc/kernel/asm-offsets.c | 8 +- arch/powerpc/kernel/time.c | 138 +++++++++++++++++++++------------- arch/powerpc/xmon/xmon.c | 8 +- arch/s390/include/asm/lowcore.h | 65 ++++++++-------- arch/s390/include/asm/processor.h | 3 + arch/s390/kernel/vtime.c | 138 ++++++++++++++++++++++------------ include/linux/kernel_stat.h | 5 +- include/linux/vtime.h | 7 +- kernel/sched/cputime.c | 16 ++-- 13 files changed, 302 insertions(+), 173 deletions(-)
