Shadow registers are consistent memory locations to which the chip
echos ring indexes in little endian format. These values need to
be endian swapped before referencing.
Note:
The register pointer declaration uses the volatile modifier which
causes warnings in checkpatch.
Per Documentation/volatile-considered-harmful.txt:
- Pointers to data structures in coherent memory which might be modified
by I/O devices can, sometimes, legitimately be volatile. A ring buffer
used by a network adapter, where that adapter changes pointers to
indicate which descriptors have been processed, is an example of this
type of situation.

The enc28j60 driver doesn't check whether the length of the packet as reported
by the hardware fits into the preallocated buffer. When stressed, the hardware
may report insanely large packets even tough the "Receive OK" bit is set. Fix

We store the firmware in its native big-endian form now, so the loop in
ace_copy() is modified to use be32_to_cpup() when writing it out.
We can forget the BSS,SBSS sections of the firmware, since we were
clearing all the device's RAM anyway. And the text,rodata,data sections
can all be loaded as a single chunk since they're contiguous (give or
take a few dozen bytes in between).

This set of patches introduces calls to the following set of functions:
usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)
In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:
USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC
In drivers/net/wireless/zd1211rw/zd_usb.c the code:
(endpoint->bEndpointAddress & USB_TYPE_MASK) == USB_DIR_OUT
is suspicious. If it is intended to use USB_ENDPOINT_DIR_MASK rather than
USB_TYPE_MASK, then the whole conditional test could be converted to a call
to usb_endpoint_is_bulk_in.
An extract of the semantic patch that makes these changes is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@r1@ struct usb_endpoint_descriptor *epd; @@
- ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) ==

if (...)
printk(KERN_WARNING "%s: Reset timed out status %04x, retrying...\n",

}
but this will become
while (!((rsst = scb_status(dev) & 0x8000) != 0) ...
because of the macro:
#define SCB_complete(s) ((s&0x8000)!=0)
so rsst can only become either 0x8000 or 0, but in the latter case the
loop ends, I think the wrong timed out status is printed. This also
cleans up similar macros.
