When the module is about the unload we release its call records. The ftrace_release function was given wrong values representing the module core boundaries, thus not releasing its call records.

The state char variable S should be reassigned, if S == 0. We are missing the state of the task that is going to sleep for the context switch events (in the raw mode). Fortunately the problem arises with the sched_switch/wake_up tracers, not the sched trace events. The formers are legacy now. But still, that was buggy.

In the event->profile_enable() failure path, we release the per cpu buffers using kfree which is wrong because they are per cpu pointers. Although free_percpu only wraps kfree for now, that may change in the future so lets use the correct way.

A couple of people have hit the WARN_ON() in drivers/char/tty_io.c, tty_open() that is unhappy about seeing the tty line discipline go away during the tty hangup. See for example http://bugzilla.kernel.org/show_bug.cgi?id=14255 and the reason is that we do the tty_ldisc_halt() outside the ldisc_mutex in order to be able to flush the scheduled work without a deadlock with vhangup_work. However, it turns out that we can solve this particular case by - using "cancel_delayed_work_sync()" in tty_ldisc_halt(), which waits for just the particular work, rather than synchronizing with any random outstanding pending work. This won't deadlock, since the buf.work we synchronize with doesn't care about the ldisc_mutex, it just flushes the tty ldisc buffers. - realize that for this particular case, we don't need to wait for any hangup work, because we are inside the hangup codepaths ourselves. so as a result we can just drop the flush_scheduled_work() entirely, and then move the tty_ldisc_halt() call to inside the mutex. That way we never expose the partially torn down ldisc state to tty_open(), and hold the ldisc_mutex over the whole sequence.

This patch fixes the m32r SMP kernel after 2.6.27. A part of the following patch breaks m32r SMP operation. > m32r: convert to generic helpers for IPI function calls > commit 7b7426c8 In the above patch, a CALL_FUNC_SINGLE_IPI was newly introduced, but the its IPI vector number was wrong in the patch code. The m32r SMP kernel hanged-up during boot operation, because the CPU_BOOT_IPI was called instead of CALL_FUNC_SINGLE_IPI (CPU_BOOT_IPI had no side effect at that time because the 2nd core had already been started up), as a result, csd_unlock() was not called, then a dead lock occurred in csd_lock_wait() after the detection of Compact Flash memory as IDE generic disk.

On a 256M filesystem, doing this in a loop: xfs_io -F -f -d -c 'pwrite 0 64m' test rm -f test eventually leads to ENOSPC. (the xfs_io command does a 64m direct IO write to the file "test") As with other block allocation callers, it looks like we need to potentially retry the allocations on the initial ENOSPC.

Currently, on ARMv6 and ARMv7, if an application tries to execute code (or garbage) on non-executable page it hangs. It caused by incorrect prefetch abort handling. Now every prefetch abort processes as a translation fault. To fix this we have to analyze instruction fault status register to figure out reason why we've got the abort and process it accordingly. To make IFSR different from DFSR we set bit 31 which is reserved in both IFSR and DFSR. This patch also tries to protect from future hangs on unexpected exceptions. An application will be killed if unexpected exception type was received. Signed-off-by: NKirill A. Shutemov <kirill@shutemov.name> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Instruction fault status register, IFSR, was introduced on ARMv6 to provide status information about the last insturction fault. It needed for proper prefetch abort handling. Now we have three prefetch abort model: * legacy - for CPUs before ARMv6. They doesn't provide neither IFSR nor IFAR. We simulate IFSR with section translation fault status for them to generalize code; * ARMv6 - provides IFSR, but not IFAR; * ARMv7 - provides both IFSR and IFAR. Signed-off-by: NKirill A.
