[patch 01/55] tile: Convert VDSO timekeeping to the precise mechanism

The code was only halfarsed converted to the new VSDO update mechanism and still uses the inaccurate base value which lacks the fractional part of xtime_nsec. Fix it up. Signed-off-by: Thomas Gleixner --- arch/tile/kernel/time.c |9 -

[patch 32/55] delayacct: Remove braindamaged type conversions

Converting cputime to timespec and timespec to nanoseconds makes no sense. Use cputime_to_ns() and be done with it. Signed-off-by: Thomas Gleixner --- kernel/delayacct.c | 18 +++--- 1 file changed, 7 insertions(+), 11 deletions(-) Index: tip/kernel/delayacct.c

[patch 37/55] net: mlx5: Use ktime_get_ns()

This code is beyond silly: struct timespec ts = ktime_get_ts(); ktime_t ktime = timespec_to_ktime(ts); Further down the code builds the delta of two ktime_t values and converts the result to nanoseconds. Use ktime_get_ns() and replace all the nonsense. Signed-off-by: Thomas Gleixner

[patch 54/55] timekeeping: Provide fast and NMI safe access to CLOCK_MONOTONIC[_RAW]

Tracers want a correlated time between the kernel instrumentation and user space. We really do not want to export sched_clock() to user space, so we need to provide something sensible for this. Using separate data structures with an non blocking sequence count based update mechanism allows us to

[patch 53/55] seqcount: Provide raw_read_seqcount()

raw_read_seqcount opens a read critical section of the given seqcount without any lockdep checking and without checking or masking the LSB. Calling code is responsible for handling that. Preparatory patch to provide NMI safe clock monotonic[_raw] accessor functions. Signed-off-by: Thomas

[patch 39/55] hwmon: ibmaem: Use ktime_get_ns()

Using the wall clock time for delta time calculations is wrong to begin with because wall clock time can be set from userspace and NTP. Such data wants to be based on clock monotonic. The calcuations also are done on a nanosecond basis. Use the nanoseconds based interface right away.
