Ben Hutchings 31b760202a sfc: Fix type of FALCON_SPI_MAX_LEN
FALCON_SPI_MAX_LEN has type size_t while other SPI lengths have type
unsigned int.  This results in warnings from min() on 64-bit

Ben Hutchings 13e9ab1143 sfc: Use CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS where appropriate
For some buffers we use a starting offset of either NET_IP_ALIGN or 0
depending on whether we believe the architecture supports efficient
access to unaligned words.  There is now a config macro specifying
whether this is the case, so check that rather than checking for
specific architectures.

Stop polling the RX_DESC_PTR_TBL to infer that a flush might have

To keep things quick, request flushes for every TX and RX queue up
front, and match up the events to requests.

Mats Erik Andersson da8de3929d 8139too: [cosmetic] fix incorrect register for flash-rom
I would like to submit a correction to the driver

     drivers/net/8139too.c,

which in no way changes the compiled driver, but does change
the value of a previously incorrect value for the configuration
register address of Flash PROM on the network processor rtl8139C.
This corrected value is in accordance with the datasheet
for rtl8139C, and in addition this new value is indeed used
in other functional drivers that use this adapter for
programming a Flash memory chip in situ. But as said,
the two new constants are never referenced in the driver
maintained by you: they are only informational and correct!

Matthew Wilcox f382a0a8e9 [netdrvr] atl1e: Don't take the mdio_lock in atl1e_probe
Lockdep warns about the mdio_lock taken with interrupts enabled then later
taken from interrupt context.  Initially, I considered changing these
to spin_lock_irq/spin_unlock_irq, but then I looked at atl1e_phy_init()
and saw that it calls msleep().  Sleeping while holding a spinlock is
not allowed either.

In the probe path, we haven't registered the interrupt handler, so
it can't poke at this card yet.  It's before we call register_netdev(),
so I don't think any other threads can reach this card either.  If I'm
right, we don't need a spinlock at all.

Seems like the spinlock for the AU1x00 ethernet device is initialised too
late, as it is already used in enable_mac(), which is called via
mii_probe() before the init takes place.

The attached patch is working here for a Linux Au1100 2.6.22.6 kernel,
and as far as I checked should also be applicable to the current head
(just line numbers differ).

this is due to some header shuffle in linux-next.  I didn't look to see what

avoid bisection breaks.

We strictly only need asm/pgtable.h, but going direct to asm includes always

the open function never does a pci_enable_device() and assumes that
