2009-12-16rtc-mv: add support for AlarmSaeed Bishara
This patch adds the Alarm support, this mode enabled when adding IORESOURCE_IRQ to the platform device resources. The patch also enables the wakeup mode, so the wakealarm sysfs file (under /sys/class/rtc/rtcX/) can be used to configure the alarm clock.

2009-12-16rtc: pcf50633: manage RTC alarm "pending" flagWerner Almesberger
Add setting and clearing of the "pending" flag of the RTC alarm. The semantics follow the UEFI specification 2.2 available at http://www.uefi.org/specs/, i.e., the "pending" flag is cleared by disabling the alarm, but not by any other condition (such as the passing of time, a successful wakeup, or setting of a new alarm.)

2009-12-16efirtc: explicitly set llseek to no_llseekJohn Kacur
Now that we've removed the BKL here, let's explicitly set llseek to no_llseek since the default llseek is not used here. The default_llseek function still contains the BKL. When we are auditing code to see if we can remove the BKL, this is one of the hidden considerations we need to take into account. i.e., is there syncronization between code that has the BKL and llseek. At the same time we remove the BKL it would be a good idea to do indicate when no llseek function is required, so we don't have to revisit this code again, when we are trying to determine if we can remove the BKL from the default_llseek.

- Call dev_set_drvdata before rtc device creation. - Use its own spinlock instead of rtc->irq_lock. Because pdata->rtc must be initialized to use the irq_lock (pdata->rtc->irq_lock). There is a small window which rtc methods can be called before pdata->rtc is initialized. And there is no need use the irq_lock to protect hardware registers. The driver's own spinlock shoule be enough. - Check pdata->rtc before calling rtc_update_irq. - Use alarm_irq_enable and remove ioctl routine. - Use devres APIs and simplify error/remove path.

2009-12-16rtc: disable hpet emulation on suspendMaxim Levitsky
I noticed that rtc wont generate interrupts after a resume from disk. Here hpet rtc emulation is used. Problem is that rtc hpet comparator, isn't reinitialized after resume. Easiest way to solve this, is always mask all hpet interrupts on suspend This is triggered, when suspending with alarm set. Otherwise, hpet driver will think it doesn't need to reinitialize the rtc comparator, thus rtc interrupts won't work. This emulation isn't need for wakealarm.

2009-12-16autofs4: always use lookup for lookupIan Kent
We need to be able to cope with the directory mutex being held during ->d_revalidate() in some cases, but not all cases, and not necessarily by us. Because we need to release the mutex when we call back to the daemon to do perform a mount we must be sure that it is us who holds the mutex so we must redirect mount requests to ->lookup() if the mutex is held.

2009-12-16autofs4: eliminate d_unhashed in path walk checksIan Kent
We unhash the dentry (in a subsequent patch) in ->d_revalidate() in order to send mount requests to ->lookup(). But then we can not rely on d_unhased() to give reliable results because it may be called at any time by any code path. The d_unhashed() function is used by __simple_empty() in the path walking callbacks but autofs mount point dentrys should have no directories at all so a list_empty() on d_subdirs should be (and is) sufficient.

2009-12-16oom-kill: fix NUMA constraint check with nodemaskKAMEZAWA Hiroyuki
Fix node-oriented allocation handling in oom-kill.c I myself think of this as a bugfix not as an ehnancement. In these days, things are changed as - alloc_pages() eats nodemask as its arguments, __alloc_pages_nodemask(). - mempolicy don't maintain its own private zonelists. (And cpuset doesn't use nodemask for __alloc_pages_nodemask()) So, current oom-killer's check function is wrong. This patch does - check nodemask, if nodemask && nodemask doesn't cover all node_states[N_HIGH_MEMORY], this is CONSTRAINT_MEMORY_POLICY. - Scan all zonelist under nodemask, if it hits cpuset's wall this faiulre is from cpuset. And - modifies the caller of out_of_memory not to call oom if __GFP_THISNODE. This doesn't change "current" behavior. If callers use __GFP_THISNODE it should handle "page allocation failure" by itself. - handle __GFP_NOFAIL+__GFP_THISNODE path. This is something like a FIXME but this gfpmask is not used now.

I don't have any need for brightness control, and its code is *completely* separate from the on/off controls implemented here. If anyone else wants it, I'd be happy to look into adding it, but I don't care enough for now. Except for the probe routines, I rewrote most of it. I also Note that I don't have any hardware documentation except for the original driver.

2009-12-16V4L/DVB (13685): Correct code taking the size of a pointerJulia Lawall

2009-12-16V4L/DVB (13680b): DocBook/media: create links for included sourcesBen Hutchings
If docs are being built in a separate directory, xmlto and xsltproc can't find included sources. Make links back to the source directory. I would much prefer to have xmlto and xsltproc look in the source directory for included entities but couldn't see how to do that. This needs to be solved in some way for 2.6.32, even if this patch isn't the right way to do it.
