printk: Add new timestamps
Subsystems (32)
v6 cover printk: Add new timestamps
printk.time=1/CONFIG_PRINTK_TIME=1 adds a unmodified local hardware clock timestamp to printk messages. The local hardware clock loses time each day making it difficult to determine exactly when an issue has occurred in the kernel log, and making it difficult to determine how kernel and hardware issues relate to each other in real time.
Add monotonic, boottime, and real clock timestamps in addition to the existing local hardware clock timestamp.

PATCH v6 1/2 time: Make fast functions return 0 before timekeeping is initialized
printk timestamps will be extended to include mono and boot time by using the fast timekeeping functions ktime_get_mono|boot_fast_ns() functions. The functions can return garbage before timekeeping is initialized resulting in garbage timestamps.
The fast time functions must return 0 before timekeeping is initialized.
v6: Separate these changes out into their own patch.

printk timestamps will be extended to include mono and boot time by using the fast timekeeping functions ktime_get_mono|boot_fast_ns() functions. The functions can return garbage before timekeeping is initialized resulting in garbage timestamps.
The fast time functions must return 0 before timekeeping is initialized.
This looks reasonable. I can queue it, but you still have feedback to address on 2/2, so I may wait until that is sorted.

PATCH v6 2/2 printk: Add monotonic, boottime, and realtime timestamps
In reply to Prarit Bhargavaprintk.time=1/CONFIG_PRINTK_TIME=1 adds a unmodified local hardware clock timestamp to printk messages. The local hardware clock loses time each day making it difficult to determine exactly when an issue has occurred in the kernel log, and making it difficult to determine how kernel and hardware issues relate to each other in real time.
Make printk output different timestamps by adding options for no timestamp, the local hardware clock, the monotonic clock, the boottime clock, and the real clock. Allow a user to pick one of the clocks by using the printk.time kernel parameter. Output the type of clock in /sys/module/printk/parameters/time so userspace programs can interpret the timestamp.
Real clock & 32-bit systems: Selecting the real clock printk timestamp may lead to unlikely situations where a timestamp is wrong because the real time without the protection of a sequence lock when printk_get_ts() is set printk_get_real_ns().
v2: Use peterz's suggested Kconfig options. Merge patchset together. Fix i386 !CONFIG_PRINTK builds.
v3: Fixed x86_64_defconfig. Added printk_time_type enum and printk_time_str for better output. Added BOOTTIME clock functionality.
v4: Fix messages, add additional printk.time options, and fix configs.
v5: Renaming of structures, and allow printk_time_set() to evaluate substrings of entries (eg: allow 'r', 'real', 'realtime'). From peterz, make fast functions return 0 until timekeeping is initialized (removes timekeeping_active & ktime_get_boot|real_log_ts() suggested by
tglx and adds ktime_get_real_offset()). Switch to a function pointer
for printk_get_ts() and reference fast functions. Make timestamp_sources enum match choice options for CONFIG_PRINTK_TIME (adds PRINTK_TIME_UNDEFINED).
v6: Define PRINTK_TIME_UNDEFINED for !CONFIG_PRINTK builds. Separate timekeeping changes into separate patch. Minor include file cleanup.

I am really nervous about the default case, despite PRINTK_TIME_UNDEFINED being declared impossible. Either set printk_get_ts to local_clock for default: (which I prefer), or return (printk_get_ts != printk_set_timestamp) ? printk_get_ts() : 0; (which at least prevents the infinite loop).

(I've asked this before) Could we add something like #ifndef PRINTK_TIME_DEBUG around the following to allow the option to chose for those that like to 'play' with the value?

You need to drop the prompt on this, as it ends up with this insane setup where you chose from the choice list, but then you can go and set the PRINTK_TIME manually to something else?
So PRINTK_TIME_REAL can be y, but PRINTK_TIME can be 2... Yuck.
I'm still annoyed enough with this Kconfig/defconfig noise in the patch that I'm going to take my own shot at it ( hopefully there's a better way, but likely it will help me understand why it was done this way :).
thanks
