2012-01-11cpu: Register a generic CPU device on architectures that currently do notBen Hutchings
frv, h8300, m68k, microblaze, openrisc, score, um and xtensa currently do not register a CPU device. Add the config option GENERIC_CPU_DEVICES which causes a generic CPU device to be registered for each present CPU, and make all these architectures select it.

2012-01-11cpu: Do not return errors from cpu_dev_init() which will be ignoredBen Hutchings
cpu_dev_init() is only called from driver_init(), which does not check its return value. Therefore make cpu_dev_init() return void. We must register the CPU subsystem, so panic if this fails. If sched_create_sysfs_power_savings_entries() fails, the damage is contained, so ignore this (as before).

2012-01-10drivers/rtc/interface.c: fix alarm rollover when day or month is out-of-rangeBen Hutchings
Commit f44f7f96a20a ("RTC: Initialize kernel state from RTC") introduced a potential infinite loop. If an alarm time contains a wildcard month and an invalid day (> 31), or a wildcard year and an invalid month (>= 12), the loop searching for the next matching date will never terminate. Treat the invalid values as wildcards.

2012-01-10backlight/ld9040.c: regulator control in the driverDonghwa Lee
This patch supports regulator power control in the driver. Current ld9040 driver was controlled power on/off sequence by callback function in the board file. But, by doing this, there's no need to register lcd power on/off callback function in the board file.

Support for the Avionic Design Xanthos backlight device got added in commit 3b96ea9ef8 ("backlight: Add support for the Avionic Design Xanthos backlight device."). That support depends on ARCH_PXA_ADX. The code that should have provided that Kconfig symbol never got submitted. It has never been possible to even build this driver. Remove it.

2012-01-11md/raid1: perform bad-block tests for WriteMostly devices too.NeilBrown
We normally try to avoid reading from write-mostly devices, but when we do we really have to check for bad blocks and be sure not to try reading them. With the current code, best_good_sectors might not get set and that causes zero-length read requests to be send down which is very confusing. This bug was introduced in commit d2eb35acfdccbe2 and so the patch is suitable for 3.1.x and 3.2.x Reported-and-tested-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Reported-and-tested-by: Art -kwaak- van Breemen <ard@telegraafnet.nl> Signed-off-by: NeilBrown <neilb@suse.de> Cc: stable@vger.kernel.org
2012-01-11md: notify the 'degraded' sysfs attribute on failure.NeilBrown
We currently only 'notify' changes to the 'degraded' attribute when it decreases, not when it increases. Notifying on failure is a little awkward as it happen in interrupt context. So instead, notify when we remove the failed device from the array, which is very soon afterwards.
