v7:
- fix type of 'flags' in memalloc_noio_save()/memalloc_noio_restore()
- rebase on v3.8-rc2-next-20130104
v6:
- replace GFP_IO with __GFP_IO to fix compile failure
/ethtool_ops is still set dynamically
inside bind().
especially as this not protected by a lock.
Looks lock isn't needed since probe/remove and open/close path
can't be concurrent.

V1:
- return -EPROBE_DEFER only for -ENODEV case as pointed

still wrong, what you should do is that when you can't get the phy, you
set status to -EPROBE_DEFER, instead of -ENODEV.
The above code does set status to to -EPROBE_DEFER when phy can't
be got, doesn't it?

This patch applies the introduced usbnet_read_cmd_nopm() and
usbnet_write_cmd_nopm() in the callback of resume and suspend
to avoid deadlock if USB runtime PM is considered into
usbnet_read_cmd() and usbnet_write_cmd().

This patch fixes memory leak in smsc95xx_suspend.
Also, it isn't necessary to bother mm to allocate 8bytes/16byte,
and we can use stack variable safely.

This patche gets the runtime PM reference count before calling
usbnet_read[write]_cmd, and puts it after completion of the
usbnet_read[write]_cmd, so that the usb control message can always
be sent to one active device in the non-PM context.

should be fine.

the race described above.
I have thought about this. IMO, pm_runtime_get_memalloc_noio should
return true always if CONFIG_PM_RUNTIME is unset.

Sorry, that doesn't work, runtime_suspend need that too because memory
