Now that the network stack can handle inbound packets with partial
checksums, we should no longer clobber the ip_summed field in the
loopback driver. This is because CHECKSUM_UNNECESSARY implies that
the checksum field is actually valid which is not true for loopback
packets since it's only partial (and thus complemented).
This allows packets from lo to then be SNATed to an external source
while still preserving the checksum's validity.

Ethtool stats are 64-bits in length. net_device_stats members are
unsigned long types. When gathering information for
a get_ethtool_stats call, the driver will call a driver-private,
inlined get_stat64() function, which returns an unsigned long value.
This call will inadvertently mask off the upper 32-bits of a stat on
32-bit machines.

The git commit 7c5026aa9b ("tg3: Add
link state reporting to UMP firmware") introduced code that waits for
previous firmware events to be serviced before attempting to submit a
new event. Unfortunately that patch contained a bug that cause the
driver to wait 2.5 seconds, rather than 2.5 milliseconds as intended.
This patch fixes that bug.
This bug revealed that not all firmware versions service driver events
though. Since we do not know which versions of the firmware do and don't
service these events, the driver needs some way to minimize the effects
of the delay. This patch solves the problem by recording a jiffies
timestamp when it submits an event to the hardware. If the jiffies
counter shows that 2.5 milliseconds have already passed, a wait is not
needed and the driver can proceed to submit a new event.

When reviewing a recent patch I noticed a potential trouble spot in the
registration of new SPI devices. The SPI master driver is told to set
the device up before adding it to the driver model, so that it's always
properly set up when probe() is called. (This is important, because in
the case of inverted chipselects, this device can make the bus misbehave
until it's properly deselected. It's got to be set up even if no driver
binds to the device.)
The trouble spot is that it doesn't first verify that no other device
has been added using that chipselect. If such a device has been added,
its configuration gets trashed. (Fortunately this has not been a common
error!)
The fix here adds an explicit check, and a mutex to protect the relevant
critical region.

in an infinite loop. To fix this, we add one last check--if the
interface number we're looking for is higher than the number of

Previously the driver was only using DMI to prevent smbus probing on
non-Abit motherboards. However, since the manual probing method is
brittle and prone to failure on some Abit motherboards (esp. the Abit
IP35 Pro) it is better to use DMI to also read the board name and then
decide whether or not to probe the bus.
At the moment, we do not have a list of valid DMI name strings to use
for existing and supported motherboards. This patch only implements DMI
probing for the IP35 Pro. For motherboards that can not yet use DMI
probing, a warning will be printed to the kernel log asking those users
to email me their dmidecode output.
The existing manual probing mechanism will be used if CONFIG_DMI is not
enabled, if DMI probing fails (for DMI-unsupported motherboards), or if
DMI probing fails and the "force" option is set (for DMI-supported
motherboards). Ideally in the longer term this manual probing method
would be removed.
This patch should be safe to apply as it does not change the probing
behaviour for most of the supported motherboards, just the IP35 Pro,
which already has regressions filed against it in 2.6.26.

When EC is in Polling mode, OS will check the EC status continually by using
the following source code:
clear_bit(EC_FLAGS_WAIT_GPE, &ec->flags);
while (time_before(jiffies, delay)) {
if (acpi_ec_check_status(ec, event))
return 0;
msleep(1);
}
But msleep is realized by the function of schedule_timeout. At the same time
although one process is already waken up by some events, it won't be scheduled
immediately. So maybe there exists the following phenomena:
a. The current jiffies is already after the predefined jiffies.
But before timeout happens, OS has no chance to check the EC
status again.
b. If preemptible schedule is enabled, maybe preempt schedule will happen
before checking loop. When the process is resumed again, maybe
timeout already happens, which means that OS has no chance to check
the EC status.
In such case maybe EC status is already what OS expects when timeout happens.
But OS has no chance to check the EC status and regards it as AE_TIME.
So it will be more appropriate that OS will try to check the EC status again
when timeout happens. If the EC status is what we expect, it won't be regarded
as timeout. Only when the EC status is not what we expect, it will be regarded
as timeout, which means that EC controller can't give a response in time.
