When the kernel is\nstopped by kgdb inside code which holds watchdog_lock then kgdb dead\nlocks in clocksource_resume_watchdog().\n\nclocksource_resume_watchdog() is called from kbdg via\nclocksource_touch_watchdog() to avoid that the clock source watchdog\nmarks TSC unstable after the kernel has been stopped.\n\nSolve this by replacing spin_lock with a spin_trylock and just return\nin case the lock is held. Not resetting the watchdog might result in\nTSC becoming marked unstable, but that\u0027s an acceptable penalty for\nusing kgdb.\n\nThe timekeeping is anyway easily screwed up by kgdb when the system\nuses either jiffies or a clock source which wraps in short intervals\n(e.g. pm_timer wraps about every 4.6s), so we really do not have to\nworry about that occasional TSC marked unstable side effect.\n\nThe second caller of clocksource_resume_watchdog() is\nclocksource_resume().

Then we enable clocksource selection at late_initcall time. This\ncauses some problems for drivers that use gettimeofday for init\ncalibration routines (specifically the es1968 driver in this case),\nwhere durring module_init, the only clocksource available is the low-res\njiffies clocksource. This may cause slight calibration errors, due to\nthe small sampling time used.\n\nIt should be noted that drivers that require fine grained time may not\nfunction on architectures that do not have better then jiffies\nresolution timekeeping (there are a few). However, this does not\ndiscount the reasonable need for such fine-grained timekeeping at init\ntime.\n\nThus the solution here is to register clocksources earlier (ideally when\nthe hardware is being initialized), and then we enable clocksource\nselection at fs_initcall (before device_initcall).\n\nThis patch should probably get some testing time in -mm, since\nclocksource selection is one of the most important issues for correct\ntimekeeping, and I\u0027ve only been able to test this on a few of my own\nboxes.\n\nSigned-off-by: John Stultz \u003cjohnstul@us.ibm.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \"David S.
