cfs_rq->tasks list is used by the load balancer to iterate
over all the tasks. Currently it holds all the entities
(both task and group entities) because of which there is
a need to check for group entities explicitly during load
balancing. This patch changes the cfs_rq->tasks list to
hold only task entities.

Currently, GART alloc_coherent tries to allocate pages with GFP_DMA32
for a device having dma_masks > 24bit < 32bits. If GART gets an
address that a device can't access to, GART try to map the address to
a virtual I/O address that the device can access to.
But Andi pointed out, "The GART is somewhere in the 4GB range so you
cannot use it to map anything < 4GB. Also GART is pretty small."
http://lkml.org/lkml/2008/9/12/43
That is, it's possible that GART doesn't have virtual I/O address
space that a device can access to. The above behavior doesn't work for
a device having dma_masks > 24bit < 32bits.
This patch restores old GART alloc_coherent behavior (before the
alloc_coherent rewrite).

x86: make GART to respect device's dma_mask about virtual mappings
I wrote the above commit to fix a GART alloc_coherent regression, that
can't handle a device having dma_masks > 24bit < 32bits, introduced by
the alloc_coherent rewrite:
http://lkml.org/lkml/2008/8/12/200
After the alloc_coherent rewrite, GART alloc_coherent tried to
allocate pages with GFP_DMA32. If GART got an address that a device
can't access to, GART mapped the address to a virtual I/O address. But
GART mapping mechanism didn't take account of dma mask, so GART could
use a virtual I/O address that the device can't access to again.
Alan pointed out:
" This is indeed a specific problem found with things like older
AACRAID where control blocks must be below 31bits and the GART
is above 0x80000000. "
The above commit modified GART mapping mechanism to take care of dma
mask. But Andi pointed out, "The GART is somewhere in the 4GB range so
you cannot use it to map anything < 4GB. Also GART is pretty small."
http://lkml.org/lkml/2008/9/12/43
That means it's possible that GART doesn't have virtual I/O address
space that a device can access to. The above commit (to modify GART
mapping mechanism to take care of dma mask) can't fix the regression
reliably so let's avoid making GART more complicated.
We need a solution that always works for dma_masks > 24bit <
32bits. That's how GART worked before the alloc_coherent rewrite.

With 2.6.27-rc3 I noticed the following messages in my boot log:

0000:01:00.0: eth0: (PCI Express:2.5GB/s:Width x1) 00:16:76:04:ff:09
The second seems correct, but the first has a silly repetition of the
PCI device before the actual message. The message originates from
e1000_eeprom_checks in e1000e/netdev.c.
With this patch below the first message becomes
e1000e 0000:01:00.0: Warning: detected DSPD enabled in EEPROM
which makes it similar to directly preceding messages.
Use dev_warn instead of e_warn in e1000_eeprom_checks() as the interface
name has not yet been assigned at that point.

Removing the module would cause a kernel oops as platform_driver_probe
failed to detect a device and unregistered the platform driver on module
init, and cleanup_module would unregister the already unregistered driver.
The suspend and resume functions weren't being called.
platform_driver support was added earlier, but without any
platform_device_register* calls I don't think it was being used. Now all
devices are registered using platform_device_register_simple and pointers
are kept to unregister the ones that the probe failed for or unregister
all devices on module shutdown. init_module no longer calls ne_init to
reduce confusion (and multiple unregister paths that caused the rmmod
oops). With the devices now registered they are added to the platform
driver and get suspend and resume events.
netif_device_detach(dev) was added before unregister_netdev(dev) when
removing the region as occationally I would see a race condition where the
device was still being used in unregister_netdev.

The loop with the timeout used "while (... && timeout--)", which means
than when the timeout occurs, "timeout" will be -1 after the loop has
exited. The code that checks if the looped exited because of a timeout
used "if (timeout <= 0)". Seems ok, except timeout is unsigned, and
(unsigned)-1 isn't less than zero!
Using "--timeout" in the loop fixes this problem, as now "timeout" will be
0 when the loop times out.
This also fixes a bug in the existing code, where it will erroneously think
a timeout occurred if the condition the loop was waiting for is satisfied
on the final iteration before a timeout.
