After XPC has been up and running on multiple partitions for any length of
time, if XPC on one of the partitions is stopped and restarted (either by
a rmmod/insmod or a system restart), it is possible for the XPCs running
on the other partitions to falsely detect a lack of heartbeat from the XPC
that was just restarted. This false detection will occur if the restarted
XPC comes up within the five-seconds preceding one of the other XPC's
heartbeat check (which occurs once every twenty seconds).
The detection of no heartbeat results in the detecting XPC deactivating
from the just restarted XPC. The only remedy is to restart one of the
XPCs and hope that one doesn't hit this five-second window on any of the
other partitions.

On alpha, we have to map some stuff in the VMALLOC space very early in the
boot process (to make SRM console callbacks work and so on, see
arch/alpha/mm/init.c). For old VM allocator, we just manually placed a
vm_struct onto the global vmlist and this worked for ages.
Unfortunately, the new allocator isn't aware of this, so it constantly
tries to allocate the VM space which is already in use, making vmalloc on
alpha defunct.
This patch forces KVA to import vmlist entries on init.

A number of drivers in drivers/gpio return -ENODEV when confronted with
missing setup parameters such as the platform data. However, returning
-ENODEV causes the driver layer to silently ignore the driver as it
assumes the probe did not find anything and was only speculative.
To make life easier to discern why a driver is not being attached, change
to returning -EINVAL, which is a better description of the fact that the
driver data was not valid.
Also add a set of dev_dbg() statements to the error paths to provide an
better explanation of the error as there may be more that one point in the
driver.

For some reason I have to slowdown clock to touchscreen device.
In atmel_spi_setup() there is comment that max_speed_hz == 0 means as slow
as possible and divider is set to maximum value. But in
atmel_spi_transfer() function is check against not zero max_speed_hz with
EINVAL returned.
Probably driver should setup divider for each transfer based on
transfer->speed_hz value, but I think that would be not necessary overhead
as all used devices have constant clock.

b44 chip has some hardware limitations, that need GFP_DMA bounce
buffers in some situations.
In order to not deplete DMA zone, we should keep allocated GFP_DMA skb
only for driver use. At rx time, we copy such skb to newly allocated
skb, reusing existing copybreak infrastructure.
On machines with low amount of memory, all skb meet the hardware limitation,
so no copy is needed. We detect this situation using a new device flag, set
to one if one GFP_DMA skb was ever allocated by b44_alloc_rx_skb().
Previously allocated skb, even outside from DMA zone will then be recycled,
to have minimal impact on DMA zone use.

The switch-over to using DMI board strings to identify abituguru3 compatible
mainboards works most of the time, but sometimes the vendor has substantially
modified the board string between BIOS revisions.
We have found that the vendor chipset identification string (provided in
brackets) changes frequently and is of no use to us. The rest of the board
string sometimes changes in subtle ways, e.g. whitespace or variations in
capitalization.
The new comparison code checks only a part of the supplied DMI board string,
trimming the bracketed content, whitespace, and ignoring case as necessary.
This fixes a bug where an IP35 Pro running an early BIOS would not be
detected without the force=1 module parameter, and also speculatively
fixes other similiar issues.

in a multisocket system have similar characteristics, e.g.
(1) provide temperature sensor interface (>=RevC && <RevF)
(2) are affected by erratum #141 (>=RevF)
Thus it is sufficient to check the revision of the boot CPU.

This was not implemented correctly for the pnx8xxx_uart driver.
[From further discussion:
Correct, you can look to it as two separate bugs:
a) the next character is not ignored while it should;
b) the status bits 31-8 are copied to the 'ch' variable while they shouldn't.
Both bugs prevent correct break signal handling (and therefore correct
behaviour of the magic SysRq key). Bug b didn't cause too much trouble
earlier because in most situations the status bits are all zero; for
this case they unfortunately aren't.
