USB: Move runtime PM callbacks to usb_device_pm_ops
USB defines usb_device_type pointing to usb_device_pm_ops that
provides system-wide PM callbacks only and usb_bus_type pointing to
usb_bus_pm_ops that provides runtime PM callbacks only. However,
the USB runtime PM callbacks may be defined in usb_device_pm_ops
which makes it possible to drop usb_bus_pm_ops and will allow us
to consolidate the handling of subsystems by the PM core code.

fs: call security_d_instantiate in d_obtain_alias V2
While trying to track down some NFS problems with BTRFS, I kept noticing I was
getting -EACCESS for no apparent reason. Eric Paris and printk() helped me
figure out that it was SELinux that was giving me grief, with the following
denial
Turns out this is because in d_obtain_alias if we can't find an alias we create
one and do all the normal instantiation stuff, but we don't do the
security_d_instantiate.
Usually we are protected from getting a hashed dentry that hasn't yet run
security_d_instantiate() by the parent's i_mutex, but obviously this isn't an
option there, so in order to deal with the case that a second thread comes in
and finds our new dentry before we get to run security_d_instantiate(), we go
ahead and call it if we find a dentry already. Eric assures me that this is ok
as the code checks to see if the dentry has been initialized already so calling
security_d_instantiate() against the same dentry multiple times is ok. With
this patch I'm no longer getting errant -EACCESS values.

grab namespace_sem

x86: Flush TLB if PGD entry is changed in i386 PAE mode
According to intel CPU manual, every time PGD entry is changed in i386 PAE
mode, we need do a full TLB flush. Current code follows this and there is
comment for this too in the code.
But current code misses the multi-threaded case. A changed page table
might be used by several CPUs, every such CPU should flush TLB. Usually
this isn't a problem, because we prepopulate all PGD entries at process
fork. But when the process does munmap and follows new mmap, this issue
will be triggered.
When it happens, some CPUs keep doing page faults:

x86, dumpstack: Correct stack dump info when frame pointer is available
Current stack dump code scans entire stack and check each entry
contains a pointer to kernel code. If CONFIG_FRAME_POINTER=y it
could mark whether the pointer is valid or not based on value of
the frame pointer. Invalid entries could be preceded by '?' sign.
However this was not going to happen because scan start point
was always higher than the frame pointer so that they could not
meet.
Commit 9c0729dc8062 ("x86: Eliminate bp argument from the stack
tracing routines") delayed bp acquisition point, so the bp was
read in lower frame, thus all of the entries were marked
invalid.
This patch fixes this by reverting above commit while retaining
stack_frame() helper as suggested by Frederic Weisbecker.

Blackfin: punt unused HDMA masks
No code uses these, and the short define names are polluting the global
namespace where they collide with things like common irq files. So just
punt the damned things. If in the future we need HDMA support, we can
make a standalone header for these things.

Blackfin/ipipe: fix deferred pipeline sync for the root stage
This patch makes sure to sync the pipeline for the root stage only
from the outer interrupt level, when resuming kernel code after an
interrupt.
This fixes a bug causing EVT15 to be spuriously popped off upon nested
interrupts, which in turn would cause the preempted kernel code to
resume without supervisor privileges.

In order to safely work around anomaly 05000491, we have to execute IFLUSH
from L1 instruction sram. The trouble with multi-core systems is that all
L1 sram is visible only to the active core. So we can't just place the
functions into L1 and call it directly. We need to setup a jump table and
place the entry point in external memory. This will call the right func
based on the active core.
In the process, convert from the manual relocation of a small bit of code
into Core B's L1 to the more general framework we already have in place
for loading arbitrary pieces of code into L1.

Blackfin: split optimization settings more
We need to place icache flush funcs into L1 inst sram to work around a
hardware anomaly. But this currently breaks SMP support as the L1 inst
sram is per-core and cannot be called directly. So in preparation for
making that work, split the two options.
Further, split out the SMP depend so that we can allow some for SMP.

I don't have the specs for this beast, but it looks a lot like the PXA

Acknowleding the edge detect status after handling one or more gpio
interrupts looks wrong. We might lose an edge which came in while we
handled the previous one.
