2009-10-13ASoC: Serialize access to dapm_power_widgets()Eero Nurkkala
Access to damp_power_widgets() is assumed to be single-threaded. Concurrent accesses to dapm_power_widgets() may result in unpredictable behavior. Calls from: close_delayed_work() soc_codec_close() soc_pcm_prepare() soc_suspend() soc_resume_deferred() to snd_soc_dapm_stream_event() do not have the codec->mutex taken to cover the call to dapm_power_widgets(). Thus, take the mutex in these paths also to assure single-threaded use of dapm_power_widgets().

2009-10-04Linux 2.6.32-rc3Linus Torvalds
I'm skipping -rc2 because the -rc1 Makefile mistakenly said -rc2, so in order to avoid confusion, I'm jumping from -rc1 to -rc3. That way, when 'uname' (or an oops report) says 2.6.32-rc2, there's no confusion about whether people perhaps meant -rc1 or -rc2.

2009-10-03tty: Avoid dropping ldisc_mutex over hangup tty re-initializationLinus Torvalds
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.

2009-10-04m32r: Fix IPI function calls for SMPToshihiro HANAWA
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.

2009-10-03ACPI: Fix bound checks for copy_from_user in the acpi /proc codeArjan van de Ven
The ACPI /proc write() code takes an unsigned length argument like any write() function, but then assigned it to a *signed* integer called "len". Only after this is a sanity check for len done to make it not larger than 4. Due to the type change a len < 0 is in principle also possible; this patch adds a check for this.
