This patch eliminates a kernel panic with the igb driver in 2.6.25-rc2 when
running on a Intel 82575 Ethernet controller with a 1000BASE-SX PHY. The
panic does not happen with the 1000BASE-T PHY, only with a SX connection.

This patch adds kdump support to the ehea driver. As the firmware doesn't free
resource handles automatically, the driver has to run an as simple as possible
free resource function in case of a crash shutdown. The function iterates over
two arrays freeing all resource handles which are stored there. The arrays are
kept up-to-date during normal runtime. The crash handler fn is triggered by the
recently introduced PPC crash shutdown reg/unreg functions.

when setting up the tx descriptors for the hardware we must account for any
padding between the header and the data we might have added previously. frame
len is the length of the frame in the air (including FCS but no padding) and
buffer len is the length of the buffer (including padding, but without FCS).
changing the way ah_setup_tx_desc is called: now excluding the FCS, since it's
easier to add that in the function where we need it.
before this fix we sent trailing zero bytes after the packet (because frame len
included the padding) which was not a big problem without WEP, but with WEP
this resultes in a wrong WEP checksum and the packet is discarded - which is
how i noticed at all ;)
an easy way to run into header padding problems, btw, is to connect to a QoS
(WME) enabled access point (eg. madwifi) - QoS data frames are 2 byte longer
and will require padding.

mlx4_table_find (for FMR MPTs) requires that ICM memory already be
mapped. Before this fix, FMR allocation depended on ICM memory
already being mapped for the MPT entry. If all currently mapped
entries are taken, the find operation fails (even if the MPT ICM table
still had more entries, which were just not mapped yet).
This fix moves the mpt find operation to fmr_enable, to guarantee that
any required ICM memory mapping has already occurred.

Use the flags in the IRQ resource to specify the type of
IRQ being requested, so that systems which do not have
level-based interrupts, or change the interrupt in some
other way can specify this without making an #ifdef mess
in the driver.
This is specifically designed to undo the change in commit
4e4fc05a2b which hardwires the
type for everyone but blackfin to IRQT_RISING, which breaks
all a number of Simtec boards which use (and setup in the
bootloader) active low IRQs.
Note, although there where originally objections due to
the use of IORESOURCE_IRQ and IRQT_ flags not sharing the

these are the same.

The e1000 driver stores the content of the PCI resources into
unsigned long's before ioremapping. This breaks on 32 bits
platforms that support 64 bits MMIO resources such as ppc 44x.
This fixes it by removing those temporary variables and passing
directly the result of pci_resource_start/len to ioremap.
The side effect is that I removed the assignments to the netdev
fields mem_start, mem_end and base_addr, which are totally useless
for PCI devices.

Add support for dual network (net_device) interface so that ethernet
and wireless can own separate ethX interfaces.
V2
- Fix the bug that bringing down and up the interface keeps rx
disabled.
- Make 'gelic_net_poll_controller()' extern , as David Woodhouse
pointed out at the previous submission.
- Fix weird usage of member names for the rx descriptor chain
V1
- Export functions which are convenient for both interfaces
- Move irq allocation/release code to driver probe/remove handlers
because interfaces share interrupts.
- Allocate skbs by using dev_alloc_skb() instead of netdev_alloc_skb()
as the interfaces share the hardware rx queue.
- Add gelic_port struct in order to abstract dual interface handling
- Change handlers for hardware queues so that they can handle dual
{source,destination} interfaces.

<4> <0>Kernel panic - not syncing: Fatal exception in interrupt
<4>
After looking at the code and the dump I think the following scenario
happened: Ifup was running on cpu2 and the interrupt arrived on cpu0.
Now virtnet_open on cpu 2 managed to execute napi_enable and disable_cb
but did not execute rx_schedule. Meanwhile on cpu 0 skb_recv_done was
called by vring_interrupt, executed netif_rx_schedule_prep, which
succeeded and therefore called disable_cb. This triggered the BUG_ON,
as interrupts were already disabled by cpu 2.
I think the proper solution is to make the call to disable_cb depend on
the atomic update of NAPI_STATE_SCHED by using netif_rx_schedule_prep
in the same way as skb_recv_done.

The PHY Lib now uses mutexes instead of spin_locks. ucc_geth
and gianfar both grab the locks in their mdio_reset functions,
so they need to use mutex_(un)lock instead. This was not caught
until someone tested it on an SMP system.

The driver needs to ack only the phy status bits that it is currently
handling and preserve the other bits for the other handlers. For
example, when reading/writing from the phy, it should not clear the link
change interrupt bit. This will cause a missing link change interrupt.

This patch converts cpmac to the new Fixed PHY infrastructure, though it
doesn't fix all the problems with that driver. I didn't even bother to
test this patch to compile, because cpmac driver is broken in several ways:
1. This driver won't compile by itself because lack of its header describing
platform data;
2. It assumes that fixed PHYs should be created by the ethernet driver.
It is wrong assumption: fixed PHYs creation is platform code authority,
driver must blindly accept bus_id and phy_id platform data variables
instead.
Also, it seem that that driver doesn't have actual in-tree users, so
nothing to fix further.
The main purpose of that patch is to get rid of the following Kconfig
warning:
scripts/kconfig/conf -s arch/powerpc/Kconfig
drivers/net/Kconfig:1713:warning: 'select' used by config symbol
'CPMAC' refers to undefined symbol 'FIXED_MII_100_FDX'

When CONFIG_PROC_FS is not set and CONFIG_PPPOL2TP is set,
we have the following warning in build:
drivers/net/pppol2tp.c: In function 'pppol2tp_init':
drivers/net/pppol2tp.c:2472: warning: label
'out_unregister_pppox_proto' defined but not used
This patches fixes this warning by adding appropriate #ifdef.

This checks if the DMA address is bigger than what the controller can manage.
It will reallocate the buffers in the GFP_DMA zone in that case.
