We make the bcm_sf2 driver override ds->ops which points to
b53_switch_ops since b53_switch_alloc() did the assignent. This is all
well and good until a second b53 switch comes in, and ends up using the
bcm_sf2 operations. Make a proper local copy, substitute the ds->ops
pointer and then override the operations.

So it can race with driver close or ethtool reconfigurations.  Fix the

The adapter->pmac_id[0] item is used for primary MAC address but
this is not true for adapter->uc_list[0] as is assumed in
be_set_uc_list(). There are N UC addresses copied first from net_device
to adapter->uc_list[1..N] and then N UC addresses from
adapter->uc_list[0..N-1] are sent to HW. So the last UC address is never
stored into HW and address 00:00:00:00;00:00 (from uc_list[0]) is used
instead.

For proper IRQ generation by DP83867 phy the INT/PWDN pin has to be
programmed as an interrupt output instead of a Powerdown input in
Configuration Register 3 (CFG3), Address 0x001E, bit 7 INT_OE = 1. The
current driver doesn't do this and as result IRQs will not be generated by
DP83867 phy even if they are properly configured in DT.

Hence, fix IRQ generation by properly configuring CFG3.INT_OE bit and
ensure that Link Status Change (LINK_STATUS_CHNG_INT) and Auto-Negotiation
Complete (AUTONEG_COMP_INT) interrupt are enabled. After this the DP83867
driver will work properly in interrupt enabled mode.

net: systemport: Fix padding vs. TSB insertion

This patch series fixes how we pad the packets submitted to the SYSTEMPORT
adapter, and how the transmit status block (prepended 8 bytes) fits in the
picture. The first patch is not technically a bug fix, but is required for the
second path to be applied and to greatly simplify the skb length calculation.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Inserting the TSB means adding an extra 8 bytes in front the of packet
that is going to be used as metadata information by the TDMA engine, but
stripped off, so it does not really help with the packet padding.

For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP)
we can end-up padding them after the TSB insertion, thus making them 64
bytes, but with the TDMA stripping off the first 8 bytes, they could
still be smaller than 64 bytes which is required to ingress the switch.

Fix this by swapping the padding and TSB insertion, guaranteeing that
the packets have the right sizes.

There is a race window between write_cache_pages calling
clear_page_dirty_for_io and XFS calling set_page_writeback, in which
the mapping for an inode is tagged neither as dirty, nor as writeback.

If the COW shrinker hits in exactly that window we'll remove the delayed
COW extents and writepages trying to write it back, which in release
kernels will manifest as corruption of the bmap btree, and in debug
kernels will trip the ASSERT about now calling xfs_bmapi_write with the
COWFORK flag for holes.  A complex customer load manages to hit this
window fairly reliably, probably by always having COW writeback in flight
while the cow shrinker runs.

This patch adds another check for having the I_DIRTY_PAGES flag set,
which is still set during this race window.  While this fixes the problem
I'm still not overly happy about the way the COW shrinker works as it
still seems a bit fragile.
