The error handling for the mpc5200 fec interrupt is broken. The intended
behaviour is like this:
* If one of FEC_IEVENT_RFIFO_ERROR and FEC_IEVENT_XFIFO_ERROR happens,
the datasheet says (MPC5200B User's Guide R1.2, p. 14-13): "When this
occurs, software must ensure both the FIFO Controller and BestComm are
soft-reset".
* On any other error (non-TFINT) interrupt, just issue a debug message.

TBIPA needs to be set to a value (on connected MDIO buses) that
doesn't conflict with PHYs on the bus. By hardcoding it to 0x1f,
we were preventing boards with PHYs at 0x1f from working properly.
Instead, scan the bus when it comes up, and find an address that
doesn't have a PHY on it. The TBI PHY configuration code then
trusts that the value in TBIPA is either safe, or doesn't matter
(ie - it's not an active bus with other PHYs).

This patch adds ibm_newemac PHY clock workaround for 440EP/440GR EMAC

The PowerPC 440GX Taishan board fails to reset EMAC3 (reset timeout

chip. The older ibm_emac driver had a workaround for that: the
EMAC_CLK_INTERNAL/EMAC_CLK_EXTERNAL macros, which toggle the Ethernet
Clock Select bit in the SDR0_MFR register. This patch does the same for
"ibm,emac-440gx" compatible chips. The workaround forces clock on -all-
EMACs, so we select clock under global emac_phy_map_lock.

only supports changing/reading rx-usecs which has special
values for 0, 1 and 3:
0 - no irq moderation whatsoever
1 - normal moderation favoring regular mixed traffic (default)
3 - best attempt at low latency possible at cost of CPU
For values between 10 and 10000 the rx-usecs defines "the minimum

Several stats registers are completely unused and we just waste pci

GOTC counters. We can just read clear them and only read the low registers.
Mii-tool can also break es2lan if it executes a MII PHY register
ioctl while the device is in autonegotiation. Unfortunately it seems
that several applications and installations still perform this ioctl
call periodically and especially in this crucial startup time. We
can fool the ioctl by providing fail safe information that mimics
the "down" link state and only perform the dangerous PHY reads once
after link comes up to fill in the real values. As long as link
stays up the information will not change.

Before getting merged, xen-blkfront was xenblk and
xen-netfront was xennet.
Temporarily adding compatibility module aliases
eases upgrades from older versions by e.g. allowing
mkinitrd to find the new version of the module.

The PS3 gelic network driver depends on the wake-on-lan support
provided by the PS3 sys manager driver. Add that dependency
to the GELIC_NET Kconfig option.
Prevents these build errors:

The IFF_UP test is a bit racey, because other entities
outside of this driver's ioctl handler can modify that
state, even though this ioctl handler runs under
lock_kernel().

Commit b716bb91 ("iwlwifi: Cancel scanning upon association") moved the
test of priv->vif in iwl{3945,4964}_mac_config_interface() outside of
where priv->mutex is held, but still tries to do mutex_unlock() on
return. This is clearly wrong and triggers a nasty lockdep warning when
this codepath is triggered. Fix this by removing the mutex_unlock().

Some mainboards/CPUs don't allow DMA masks bigger than a certain limit.
Some VIA crap^h^h^h^hdevices have an upper limit of 0xFFFFFFFF. So in this
case a 64-bit b43 device would always fail to acquire the mask.
Implement a workaround to fallback to lower DMA mask, as we can always
also support a lower mask.

This adds a workaround for invalid bluetooth SPROM settings
on ASUS PCI cards.
This will stop the microcode from poking with the BT GPIO line.
This fixes data transmission on this device, as the BT GPIO line
is used for something TX related on this device
(probably the power amplifier or the radio).
This also adds a modparam knob to help debugging this in the future,
as more devices with this bug may show up.
