cache removal fallout. Some other minor fixes all around.
1) Fix RCU of cached routes, particular of output routes which require
liberation via call_rcu() instead of call_rcu_bh(). From Eric
Dumazet.
2) Make sure we purge net device references in cached routes properly.

Pull battery updates from Anton Vorontsov:
"The tag contains just a few battery-related changes for v3.6. It's is
all pretty straightforward, except one thing.
One of our patches added thermal support for power supply class, but
thermal/ subsystem changed under our feet. We (well, Stephen, that
is) caught the issue and it was decided[1] that I'd just delay the
battery pull request, and then will fix it up by merging upstream back
into battery tree at the specific commit.
That's not all though: another[2] small fixup for thermal subsystem
was needed to get rid of a warning in power supply subsystem (the
warning was not drivers/power's "fault", the thermal registration
function just needed a proper const annotation, which is also done by
a small commit on top of the merge.
So, to sum this up:
- The 'master' branch of the battery tree was in the -next tree for
weeks, was never rebased, altered etc. It should be all OK;
- Although, for-v3.6 tag contains the 'master' branch + merge + the
warning fix.

This fixes a few issues in rbd_header_from_disk():
- There is a check intended to catch overflow, but it's wrong in
two ways.
- First, the type we don't want to overflow is size_t, not
unsigned int, and there is now a SIZE_MAX we can use for
use with that type.
- Second, we're allocating the snapshot ids and snapshot
image sizes separately (each has type u64; on disk they
grouped together as a rbd_image_header_ondisk structure).
So we can use the size of u64 in this overflow check.
- If there are no snapshots, then there should be no snapshot
names. Enforce this, and issue a warning if we encounter a
header with no snapshots but a non-zero snap_names_len.
- When saving the snapshot names into the header, be more direct
in defining the offset in the on-disk structure from which
they're being copied by using "snap_count" rather than "i"
in the array index.
- If an error occurs, the "snapc" and "snap_names" fields are
freed at the end of the function. Make those fields be null
pointers after they're freed, to be explicit that they are
no longer valid.
- Finally, move the definition of the local variable "i" to the
innermost scope in which it's needed.

All of the callers of rbd_req_sync_op() except one pass a non-null
"ops" pointer. The only one that does not is rbd_req_sync_read(),
which passes CEPH_OSD_OP_READ as its "opcode" and, CEPH_OSD_FLAG_READ
for "flags".
By allocating the ops array in rbd_req_sync_read() and moving the
special case code for the null ops pointer into it, it becomes
clear that much of that code is not even necessary.
In addition, the "opcode" argument to rbd_req_sync_op() is never
actually used, so get rid of that.

The "id" field of an rbd device structure represents the unique

image will have another id--the image id--and each snapshot has its
own id as well. The simple name "id" no longer conveys the
information one might like to have.

In rbd_header_add_snap() there is code to set snapc->seq to the
just-added snapshot id. This is the only remnant left of the
use of that field for recording which snapshot an rbd_dev was
associated with. That functionality is no longer supported,
so get rid of that final bit of code.
Doing so means we never actually set snapc->seq any more. On the
server, the snapshot context's sequence value represents the highest
snapshot id ever issued for a particular rbd image. So we'll make
it have that meaning here as well. To do so, set this value
whenever the rbd header is (re-)read. That way it will always be
consistent with the rest of the snapshot context we maintain.

In rbd_header_set_snap(), there is logic to make the snap context's
seq field get set to a particular snapshot id, or 0 if there is no
snapshot for the rbd image.
This seems to be an artifact of how the current snapshot id for an
rbd_dev was recorded before the rbd_dev->snap_id field began to be
used for that purpose.
There's no need to update the value of snapc->seq here any more, so
stop doing it. Tidy up a few local variables in that function
while we're at it.

In what appears to be an artifact of a different way of encoding
whether an rbd image maps a snapshot, __rbd_refresh_header() has
code that arranges to update the seq value in an rbd image's
snapshot context to point to the first entry in its snapshot
array if that's where it was pointing initially.
We now use rbd_dev->snap_id to record the snapshot id--using the
special value CEPH_NOSNAP to indicate the rbd_dev is not mapping a
snapshot at all.
There is therefore no need to check for this case, nor to update the
seq value, in __rbd_refresh_header(). Just preserve the seq value
that rbd_read_header() provides (which, at the moment, is nothing).

When the driver detects that the clock time is invalid, it attempts to
write a sane time into the hardware. We curently assume that everything
is OK if those writes succeeded. But it is better to re-read the time
from the hardware to ensure that the new settings got there OK.

r9701_get_datetime() calls rtc_valid_tm() and returns the value returned
by rtc_valid_tm(), which can be used in the `if', so calling
rtc_valid_tm() a second time is not required.

The pl031 interrupt is shared between the timer part and the clockwatch
part of the same HW block on the ux500, so mark it IRQF_SHARED on this
variant.
This patch also adds the IRQF_NO_SUSPEND flag to the rtc irq on all
variants as we don't want this pretty important IRQ to be disabled in
suspend.
