It's *wrong* to have
			#define log2(n) ffz(~(n))
It should be *reversed*:
			#define log2(n) flz(~(n))
or
			#define log2(n) fls(n)
or just use
			ilog2(n) defined in linux/log2.h.

This patch follows the last solution, recommended by Andrew Morton.

Driver for the CompactFlash slot on the PA Semi Electra eval board. It's
a simple device sitting on localbus, with interrupts and detect/voltage
control over GPIO.

The driver is implemented as an of_platform driver, and adds localbus
as a bus being probed by the of_platform framework.

This memcpy looks so strange, in fact it's merely a pointer dereference, so I
change the parameter's type to refer it more directly, this could make the
memcpy not needed anymore.

In the function nbd_read_stat where nbd_find_request is only once called, the
parameter served should be transformed accordingly.

The Synchronous Serial Controller (SSC) on Atmel microprocessors are
capable of tranceiving many frame based protocols, like I2S.  Tested on the
AT32AP7000/ATSTK1000.

This driver is used in the ALSA sound driver for the AT73C213 external DAC
on the ATSTK1000 development board for AVR32.  This sound driver will be
submitted soon.

Hardware documentation can be found in the AT32AP7000 data sheet, which can
be downloaded from

main change:
* greatly improve per-NIC probe diagnostic output.  Similar to other
  net drivers, print out MAC address, PHY info, and various hardware and
  software flags that may be relevant.

other changes:
* similar to other net drivers, only print the initial version message
  when we have found at least one board.

* don't bother to print error message when pci_enable_device() fails,
  it will do so for us.

* use dev_printk() rather than printk() in nv_probe().  This gives
  use a standardized output similar to the rest of the kernel, and
  eliminates the need to manually print out PCI bus id.

* use DRV_NAME constant where appropriate

* clean struct pci_driver indentation
