Some further updates for net-next:
 * fix network-manager which was broken by the previous changes
 * fix delete-station events, which were broken by me making the
   genlmsg_end() mistake
 * fix a timer left running during suspend in some race conditions
   that would cause an annoying (but harmless) warning
 * (less important, but in the tree already) remove 80+80 MHz rate
   reporting since the spec doesn't distinguish it from 160 MHz;
   as the bitrate they're both 160 MHz bandwidth

operations" subsection for information on where to use these.
(*) dma_wmb();
(*) dma_rmb();
These are for use with consistent memory to guarantee the ordering
of writes or reads of shared memory accessible to both the CPU and a
DMA capable device.
For example, consider a device driver that shares memory with a device
and uses a descriptor status value to indicate if the descriptor belongs
to the device or the CPU, and a doorbell to notify it when new
descriptors are available:
if (desc->status != DEVICE_OWN) {
/* do not read data until we own descriptor */
dma_rmb();
/* read/modify data */
read_data = desc->data;
desc->data = write_data;
/* flush modifications before status update */
dma_wmb();
/* assign ownership */
desc->status = DEVICE_OWN;
/* force memory to sync before notifying device via MMIO */
wmb();
/* notify device of new descriptors */
writel(DESC_NOTIFY, doorbell);
}
The dma_rmb() allows us guarantee the device has released ownership
before we read the data from the descriptor, and he dma_wmb() allows
us to guarantee the data is written to the descriptor before the device
can see it now has ownership. The wmb() is needed to guarantee that the
cache coherent memory writes have completed before attempting a write to
the cache incoherent MMIO region.
See Documentation/DMA-API.txt for more information on consistent memory.
