The r8169 driver supports 3 different families of network chips
(RTL8169, RTL8168 and RTL8101). When an unknown version is found, the
driver currently always defaults to the RTL8169 variant. This has very
little chance to ever work for chips of the other families. So better
define a per-family default.

Both atl1.c and atl2.c include atlx.h, which defines some modinfo

If we loaded the driver with out a SFP module plugged in it would
leave it in a state that make it later unable to link when a module
was plugged in. This patch corrects that by:
ixgbe_probe() - moving the check for IXGBE_ERR_SFP_NOT_PRESENT from
after get_invariants() to after reset_hw() as now reset_hw() is
where this condition will be indentified.
ixgbe_reset_hw_82598() - Enable this function to now return
IXGBE_ERR_SFP_NOT_PRESENT.
ixgbe_identify_sfp_module_generic() - This where the lack of SFP
module is detected. Modifications are added to allow a different
return value for modules that just haven't been plugged in yet.
Other functions were updated to allow correct logging.

Based on previous patch from Jesper Dangaard Brouer.
The RNBC (Receive No Buffers Count) register for the 82576, indicate
that frames were received when there were no available buffers in host
memory to store those frames (receive descriptor head and tail
pointers were equal). The packet is still received by the NIC if
there is space in the FIFO on the NIC.
As the RNBC value is not a packet drop, the driver stores this value
in net_stats.rx_fifo_errors to indicate that there were no system
buffers available for the incoming packet. Actual dropped packets
are counted in the MPC value.
Saving the stats in dev->net_stats makes it visible via
/proc/net/dev as "fifo", and thus viewable to ifconfig
as "overruns" and 'netstat -i' as "RX-OVR".
The Receive No Buffers Count (RNBC) can already be queried by
ethtool -S as "rx_no_buffer_count".

Implement reading the per queue drop stats register
RQDPC (Receive Queue Drop Packet Count). It counts the number of
packets dropped by a queue due to lack of descriptors available.
Notice RQDPC (Receive Queue Drop Packet Count) stats only gets
incremented, if the DROP_EN bit it set (in the SRRCTL register
for that queue). If DROP_EN bit is NOT set, then the some what
equivalent count is stored in RNBC (not per queue basis).
The RQDPC register is only 12 bit, thus the precision might
suffer due to overrun in-netween the watchdog polling interval.

This reverts commit 33f00dcedb.
While it was a good idea to try to use the mm/vmalloc.c allocator instead
of our own (in fact, ours is itself a dup on an old variant of the vmalloc
one), unfortunately, the approach is terminally busted since
dma_alloc_coherent() can be called at interrupt time or in atomic contexts
and there's little chances we'll make the code in mm/vmalloc.c cope with\ that :-(
Until we can get the generic code to forbid that idiocy and fix all
drivers abusing it, we pretty much have no choice but revert to
our custom virtual space allocator.
There's also a problem with SMP safety since freeing such mapping
would require an IPI which cannot be done at interrupt time.
However, right now, I don't think we support any platform that is
both SMP and has non-coherent DMA (don't laugh, I know such things
do exist !) so we can sort that out later.

On the 865, but not the 855, the clflush we do appears to not actually make
it out to the hardware all the time. An easy way to safely reproduce was
X -retro, which would show that some of the blits involved in drawing the
lovely root weave didn't make it out to the hardware. Those blits are 32
bytes each, and 1-2 would be missing at various points around the screen.
Other experimentation (doing more clflush, doing more AGP chipset flush,
poking at some more device registers to maybe trigger more flushing) didn't
help. krh came up with the wbinvd as a way to successfully get all those
blits to appear.

The pitch field is an exponent on pre-965, so we were rejecting buffers
on 8xx that we shouldn't have. 915 got lucky in that the largest legal
value happened to match (8KB / 512 = 0x10), but 8xx has a smaller tile width.
Additionally, we programmed that bad value into the register on 8xx, so the
only pitch that would work correctly was 4096 (512-1023 pixels), while others
would probably give bad rendering or hangs.

The current default file mode is 02767 and dir mode is 0777. This is
extremely "loose". Given that CIFS is a single-user protocol, these
permissions allow anyone to use the mount -- in effect, giving anyone on
the machine access to the credentials used to mount the share.
Change this by making the default permissions restrict write access to
the default owner of the mount. Give read and execute permissions to
everyone else. These are the same permissions that VFAT mounts get by
default so there is some precedent here.
Note that this patch also removes the mandatory locking flags from the
default file_mode. After having looked at how these flags are used by
the kernel, I don't think that keeping them as the default offers any
real benefit. That flag combination makes it so that the kernel enforces
mandatory locking.
Since the server is going to do that for us anyway, I don't think we
want the client to enforce this by default on applications that just
want advisory locks. Anyone that does want this behavior can always
enable it by setting the file_mode appropriately.

There's no reason to limit the size of a symlink that we can read to

the buffer. The size of the header has already been accounted for when
creating the slabcache, so CIFSMaxBufSize should be the correct size to
