quota: Fix dquot_transfer for filesystems different from ext4

Commit fd8fbfc1 modified the way we find amount of reserved space
belonging to an inode. The amount of reserved space is checked
from dquot_transfer and thus inode_reserved_space gets called
even for filesystems that don't provide get_reserved_space callback
which results in a BUG.
Fix the problem by checking get_reserved_space callback and return 0 if
the filesystem does not provide it.

Bail out if we don't find an enclosing IOC. Previously, if we didn't
find one, we tried to set things up using garbage for the SBA/IOC register
address, which causes a crash.
This crash only happens if firmware supplies a defective ACPI namespace, so
it doesn't fix any problems in the field.

Commit 15b8dd53f5ffa changed the string in info->hardware_id from a static
array to a pointer and added a length field. But instead of changing
"sizeof(array)" to "length", we changed it to "sizeof(length)" (== 4),
which corrupts the string we're trying to null-terminate.
We no longer even need to null-terminate the string, but we *do* need to
check whether we found a HID. If there's no HID, we used to have an empty
array, but now we have a null pointer.
The combination of these defects causes this oops:
Unable to handle kernel NULL pointer dereference (address 0000000000000003)
modprobe[895]: Oops 8804682956800 [1]

While investigating a kmemleak detected leak, I encountered the
agp_add_bridge function. It appears to be responsible for freeing
the agp_bridge_data in the case of a failure, but it is only doing
so for some errors.
Fix it to always free the bridge data if a failure condition is
encountered.

Currently Nouveau will unvalidate all buffers if it is forced to wait on
one, and then start revalidating from the beginning. While doing so, it
destroys the operation fence, causing nouveau_fence_emit to crash.
This patch fixes this bug by taking the fence object out of validate_op
and creating it just before emit. The fence pointer is initialized to 0
and unref'ed unconditionally.
In addition to fixing the bug, this prevents its reintroduction and
simplifies the code.

The below is mainly an educated guess at what's going on, docs would
sure be handy... NVIDIA? :P
It appears it's possible for a ctxprog to run even while a GPU exception
is pending. The GF8 and up ctxprogs appear to have a small snippet of
code which detects this, and stalls the ctxprog until it's been handled,
which essentially looks like:
if (r2 & 0x00008000) {
r0 |= 0x80000000;
while (r0 & 0x80000000) {}
}
I don't know of any way that flag would get cleared unless the driver
intervenes (and indeed, in the cases I've seen the hang, nothing steps
in to automagically clear it for us). This patch causes the driver to
clear the flag during the PGRAPH IRQ handler.

This should avoid a race condition on nv0x, if we're doing it with
actual PGRAPH objects and a there's a fence within the FIFO DMA fetch
area when a context switch kicks in.
In that case we get an ILLEGAL_MTHD interrupt as expected, but the
values in PGRAPH_TRAPPED_ADDR aren't calculated correctly and they're
almost useless (e.g. you can see ILLEGAL_MTHDs for the now inactive
channel, with a wrong offset/data pair).

R300 family will hard lockup if host path read cache flush is
done through MMIO to HOST_PATH_CNTL. But scheduling same flush
through ring seems harmless. This patch remove the hdp_flush
callback and add a flush after each fence emission which means
a flush after each IB schedule. Thus we should have same behavior
without the hard lockup.
Tested on R100,R200,R300,R400,R500,R600,R700 family.
