2005-09-07[PATCH] detect soft lockupsIngo Molnar
This patch adds a new kernel debug feature: CONFIG_DETECT_SOFTLOCKUP. When enabled then per-CPU watchdog threads are started, which try to run once per second. If they get delayed for more than 10 seconds then a callback from the timer interrupt detects this condition and prints out a warning message and a stack dump (once per lockup incident). The feature is otherwise non-intrusive, it doesnt try to unlock the box in any way, it only gets the debug info out, automatically, and on all CPUs affected by the lockup.

2005-07-16[MTD] NAND: Fix broken bad block scan for 16 bit devicesThomas Gleixner
The previous change to read a single byte from oob breaks the bad block scan on 16 bit devices, when the byte is on an odd address. Read the complete oob for now. Remove the unused arguments from check_short_pattern() Move the wait for ready function so it is only executed when consecutive reads happen. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-06-29[MTD] NAND: Reorganize chip lockingThomas Gleixner
The code was wrong in several aspects. The locking order was inconsistent, the device aquire code did not reset a variable after a wakeup and the wakeup handling was not working for applications where multiple chips are sharing a single hardware controller. When a hardware controller is available the locking is now reduced to the hardware controller lock and the waitqueue is moved to the hardware controller structure in order to avoid a wake_up_all(). The problem was pointed out by Ben Dooks, who also found the missing variable reset as main cause for his deadlock problem. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

This reworks the XIP locking to make sure no lock primitive is ever called from XIP disabled paths even if in theory they should not cause any reschedule. Relying on the current spinlock implementation is rather fragile and not especially clean from an abstraction pov. The recent RT work makes it even more obvious.
