The rtc-omap driver currently assumes that the rtc's registers are at a
fixed address and already mapped into virtual memory space. Remove those
assumptions so the same driver can be used for similar devices that reside
at different physical addresses (e.g., TI's DA8xx/OMAP-L13x SoC's).
Also allow the possibility for the timer and alarm interrupts to use the
same IRQ.

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.

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.

We need to be able to cope with the directory mutex being held during

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.

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.

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.
