2013-08-12n_tty: Fix termios_rwsem lockdep false positivePeter Hurley
Lockdep reports a circular lock dependency between atomic_read_lock and termios_rwsem [1]. However, a lock order deadlock is not possible since CPU1 only holds a read lock which cannot prevent CPU0 from also acquiring a read lock on the same r/w semaphore. Unfortunately, lockdep cannot currently distinguish whether the locks are read or write for any particular lock graph, merely that the locks _were_ previously read and/or write. Until lockdep is fixed, re-order atomic_read_lock so termios_rwsem can be dropped and reacquired without triggering lockdep.

2013-08-05vt: make the default color configurableClemens Ladisch
The virtual console has (undocumented) module parameters to set the colors for italic and underlined text, but the default text color was hardcoded for some reason. This made it impossible to change the color for startup messages, or to set the default for new virtual consoles. Add a module parameter for that, and document the entire bunch. Any hacker who thinks that a command prompt on a "black screen with white font" is not supicious enough can now use the kernel parameter vt.color=10 to get a nice, evil green.

2013-08-05serial: mxs: remove the MXS_AUART_DMA_CONFIGHuang Shijie
The MXS_AUART_DMA_CONFIG is originally used to check if the DT node is configured with the DMA property. But now, the MXS_AUART_DMA_CONFIG is set unconditionally in the serial_mxs_probe_dt(), so the check in the mxs_auart_settermios() is not necessary anymore. This patch removes this macro.

2013-08-05serial: mxs: enable the DMA only when the RTS/CTS is validHuang Shijie
The original DMA support works only when RTS/CTS is enabled. (see the "e800163 serial: mxs-auart: add the DMA support for mx28") But after several patches, DMA support has lost this limit. (see the "bcc20f9 serial: mxs-auart: move to use generic DMA helper") So an UART without the RTS/CTS lines may also enables the DMA support, in which case the UART may gets unpredictable results. This patch adds an optional property for the UART DT node which indicates the UART has RTS and CTS lines, and it also means you enable the DMA support for this UART. This patch also adds a macro MXS_AUART_RTSCTS, and uses it to check RTS/CTS before we enable the DMA for the UART.

Here is the short-changelog: This round of parisc updates includes mostly fixes for the C8000 workstation. We have a new defconfig file for this machine, as well as fixes for it's serial port, the AGP driver and the cache routines to cope with the vmas of the FireGL card in a C8000.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management fixes from Rafael Wysocki: - Revert two cpuidle commits added during the 3.8 development cycle that turn out to have introduced a significant performance regression as requested by Jeremy Eder. - The recent patches that made the freezer less heavy-weight introduced a regression causing user-space-driven hibernation using the ioctl() interface to block indefinitely when the hibernate process executes try_to_freeze(). Fix from Colin Cross addresses this by adding a process flag to mark the hibernate/suspend process to inform the freezer that that process should be ignored. - One of the recent cpufreq reverts uncovered a problem in the core causing the cpufreq driver module refcount to become negative after a system suspend-resume cycle. Fix from Rafael J Wysocki. - The evaluation of the ACPI battery _BIX method has never worked correctly, because the commit that added support for it forgot to take the "Revision" field in the return package into account. As a result, the reading of battery info doesn't work at all on some systems, which is addressed by a fix from Lan Tianyu. * tag 'pm+acpi-3.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: freezer: set PF_SUSPEND_TASK flag on tasks that call freeze_processes ACPI / battery: Fix parsing _BIX return value cpufreq: Fix cpufreq driver module refcount balance after suspend/resume Revert "cpuidle: Quickly notice prediction failure for repeat mode" Revert "cpuidle: Quickly notice prediction failure in general case"
