This change forces the link down when a mailbox timeout has occurred.
Previously it was possible for a mailbox timeout to occur but for the
interface to stay up. The problem with this was that it became possible
for an interface to stay up and miss multiple requests resulting in a
possible issue since the interface will be running in an unknown state.

Add support for the anti-spoofing feature in the HW. Packets from
VF devices with spoofed MAC addresses or VLAN tags will be blocked
and an event generated. When the watchdog task runs it will call a
function to check if any spoof events occurred. If an event was
detected then a warning message is dumped to the system log.

This patch does the following:
1. Changes the existing supported device id's so now DH89xxCC is not supported when EEPROM is not read.
2. Adds two more device ids for DH89xxCC in backplane mode and SFP.
3. Driver now initializes previously possibly uninitialized value in igb_reset_mdicnfg_82580().

Low level drivers may behave differently depending on the current
link->lpm_policy. During ata_eh_set_lpm(), DIPM enable commands are
issued after the successful completion of ap->ops->set_lpm(), which
means that the controller is already in the target state. This causes
DIPM enable commands to be processed with mismatching controller power
state and link->lpm_policy value.
In ahci, link->lpm_policy is used to ignore certain PHY events if LPM
is enabled; however, as DIPM commands are issued with stale
link->lpm_policy, they sometimes end up triggering these conditions
and get aborted leading to LPM configuration failure.
Fix it by updating link->lpm_policy before issuing DIPM enable
commands.

ata_qc_complete() contains special handling for certain commands. For
example, it schedules EH for device revalidation after certain
configurations are changed. These shouldn't be applied to EH
commands but they were.
In most cases, it doesn't cause an actual problem because EH doesn't
issue any command which would trigger special handling; however, ACPI
can issue such commands via _GTF which can cause weird interactions.
Restructure ata_qc_complete() such that EH commands are always passed
on to __ata_qc_complete().

While separating out BMDMA irq handler from SFF, commit c3b28894
(libata-sff: separate out BMDMA irq handler) incorrectly made
__ata_sff_port_intr() consider an IRQ to be an idle one if the host
state was transitioned to HSM_ST_ERR by ata_bmdma_port_intr().
This makes BMDMA drivers ignore IRQs reporting host bus error which
leads to timeouts instead of triggering EH immediately. Fix it by
making __ata_sff_port_intr() consider the IRQ to be an idle one iff
the state is HSM_ST_IDLE. This is equivalent to adding HSM_ST_ERR to
the "break"ing case but less error-prone.

If we are registering an i2c device that has a device tree node like
this real-world example:
rtc@68 {
compatible = "dallas,ds1337";
reg = <0x68>;
};
of_i2c_register_devices() will try to load a module called ds1337.ko.
There is no such module, so it will fail. If we look in modules.alias
we will find entries like these:
.
.
.
alias i2c:ds1339 rtc_ds1307
alias i2c:ds1338 rtc_ds1307
alias i2c:ds1337 rtc_ds1307
alias i2c:ds1307 rtc_ds1307
alias i2c:ds1374 rtc_ds1374
.
.
.
The module we want is really called rtc_ds1307.ko. If we request a
module called "i2c:ds1337", the userspace module loader will do the
right thing (unless it is busybox) and load rtc_ds1307.ko. So we add
the I2C_MODULE_PREFIX to the request_module() string.

The default for non-READ_BACK GPIO regs is to have the clear bits set;
this means that our original errata fix was too simplistic. This
changes it to the following behavior:
- when setting GPIOs, ignore the higher order bits (they're for
clearing, we don't need to care about them).
- when clearing GPIOs, keep all the bits, but unset (via XOR) the
lower order bit that negates the clear bit that we care about. That
is, if we're clearing GPIO 26 (val = 0x04000000), we first XOR what's
currently in the register with 0x0400 (GPIO 26's SET bit), and then
OR that with the GPIO 26's CLEAR bit.

The edge detect status GPIOs function differently from the other atomic

but writing 1 to the lower bits also clears the bit.
This means that read-modify-write doesn't actually work for it, so don't
apply the errata here. If a negative edge status gets lost after
