* ltc4215/ltc4245: Discard obsolete detect methodsJean Delvare2009-10-04
| | | | | | | | | | | | | | There is no point in implementing a detect callback for the LTC4215 and LTC4245, as these devices can't be detected. It was there solely to handle "force" module parameters to instantiate devices, but now we have a better sysfs interface that can do the same. So we can get rid of the ugly module parameters and the detect callbacks. This shrinks the binary module sizes by 36% and 46%, respectively.

| | | | | | | | | | | | | | There is no point in implementing a detect callback for the MAX6875, as this device can't be detected. It was there solely to handle "force" module parameters to instantiate devices, but now we have a better sysfs interface that can do the same. So we can get rid of the ugly module parameters and the detect callback. This basically divides the binary module size by 2.

| * m32r: Fix IPI function calls for SMPToshihiro HANAWA2009-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 7b7426c8a615cf61df9a77b9df7d5b75d91e3fa0 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.

* | tty: Avoid dropping ldisc_mutex over hangup tty re-initializationLinus Torvalds2009-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | | | | ARM: 5728/1: Proper prefetch abort handling on ARMv6 and ARMv7Kirill A. Shutemov2009-10-02

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: Kirill A. Shutemov <kirill@shutemov.name> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

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: Kirill A.

The modified expression results in the apparent /dev/mem size being 2 bytes smaller than what it actually is. This patch reworks the expression to correctly check the address, while maintaining use of a valid address to __pa().
