git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management fixes from Rafael Wysocki: "These are three stable-candidate fixes, one for the ACPI thermal driver and two for cpufreq drivers. Specifics: - A workqueue is destroyed too early during the ACPI thermal driver module unload which leads to a NULL pointer dereference in the driver's remove callback. Fix from Aaron Lu. - A wrong argument is passed to devm_regulator_get_optional() in the probe routine of the cpu0 cpufreq driver which leads to resource leaks if the driver is unbound from the cpufreq platform device. Fix from Lucas Stach. - A lock is missing in cpufreq_governor_dbs() which leads to memory corruption and NULL pointer dereferences during system suspend/resume, for example. Fix from Bibek Basu" * tag 'pm+acpi-3.15-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / thermal: fix workqueue destroy order cpufreq: cpu0: drop wrong devm usage cpufreq: remove race while accessing cur_policy

2014-05-29staging: ion: shrink highmem pages on kswapdHeesub Shin
ION system heap keeps pages in its pool for better performance. When the system is under memory pressure, slab shrinker calls the callback registered and then the pages pooled get freed. When the shrinker is called, it checks gfp_mask and determines whether the pages from highmem need to be freed or the pages from lowmem. Usually, slab shrinker is invoked on kswapd context which gfp_mask is always GFP_KERNEL, so only lowmem pages are released on kswapd context. This means that highmem pages in the pool are never reclaimed until direct reclaim occurs. This can be problematic when the page pool holds excessive amounts of highmem. For now, the shrinker callback cannot know exactly which zone should be targeted for reclamation, as enough information are not passed to. Thus, it makes sense to shrink both lowmem and highmem zone on kswapd context.

2014-05-29staging: ion: remove struct ion_page_pool_itemHeesub Shin
The page pool uses an internal data structure, ion_page_pool_item, for wrapping pooled pages and constructing a list.

And we need to also enable ecc hardware support for am43xx. - Enable the modem support for n900 that was dropped earlier because we had to fix the related hwmod entry first with patch ARM: OMAP2+: Fix ssi hwmod entry to allow idling. - And finally, add the omap2 clock dts files.

2014-05-29serial: kgdb_nmi: Improve console integration with KDB I/ODaniel Thompson
kgdb_nmi_tty_enabled is used for two unrelated purposes, namely to suppress normal TTY input handling and to suppress console output (although it has no effect at all on TTY output). A much better way to handle muting the console is to not have to mute it in the first place! That's what this patch does.

2014-05-29serial: cpm_uart: No LF conversion in put_poll_char()Daniel Thompson
In (c7d44a02a serial_core: Commonalize crlf when working w/ a non open console port) the core was modified to make the UART poll_put_char() automatically convert LF to CRLF. This driver's poll_put_char() adds a CR itself and this was not disabled by the above patch meaning currently it sends two CR characters. The code to issue a character is shared by the console write code (where driver must do LF to CRLF conversion, although it can make use of the uart_console_write() helper function) and the poll_put_char (where driver must not do the conversion). For that reason we add a flag rather than simply rip out the conversion code.

If scan has not finished in some reasonable time (10sec), interpret it as if firmware error occurs but was not reported. Firmware should report scan completion for every scan request, so it is error condition indeed. Perform firmware recovery procedure.

2014-05-29wil6210: limit fw error recovery attemptsVladimir Kondratiev
In case there is something fundamentally wrong with the firmware (example: RF cable disconnected), FW will always crash immediately after reset. This leads to infinite fw error recovery loop. Count consecutive unsuccessful error recovery attempts in a short period of time, and stop doing recovery after some reasonable count. It is still possible to manually reset fw doing interface down/up sequence. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
