In commit b0302ab, the rtlwifi family of drivers was converted to use
asynchronous firmware loading. Unfortumately, the implementation was
racy, and the ieee80211 routines could be started before rtl_init_core()
was called to setup the data.
This patch fixes the bug noted in https://bugzilla.kernel.org/show_bug.cgi?id=43187.

- Add routing_algo
- Remove date from README:
The date has to be updated when a patch touches the README. Therefore, nearly
every feature will modify this date. It can happens quite often that not only
one feature is currently in development or waiting on the mailinglist. This
creates merge conflicts when applying a patchset.
The date itself doesn't provide any additional information when this file is
only available in a release tarball or as part of a SCM repository.

This eliminated most of the remaining users of btfixup.
There are some complications because of the special cases we
have for sun4d, leon, and some flavors of viking.
It was found that there are no cases where a flush_page_for_dma
method was not hooked up to something, so the "noflush" iommu
methods were removed.

sun4d.

This set of changes displays one major danger of btfixup, interface
signatures are not always type checked fully. As seen here the iounit

These were used on sun4c during floppy data transfers since on that
chip we had to lock the cpu mappings into the TLB because we cannot
take a TLB miss during the assembler floppy interrupt handler that
does the data transfer.
That is no longer necessary since we've removed sun4c support, thus
this stuff can disappear completely.

In case of a client X roaming from a generic node A to another node B, it is
possible that a third node C gets A's OGM but not B's. At this point in time, if
C wants to send data to X it will send a unicast packet destined to A. The
packet header will contain A's last ttvn (C got A's OGM and so it knows it).
The packet will travel towards A without being intercepted because the ttvn
contained in its header is the newest for A.
Once A will receive the packet, A's state will not report to be in a "roaming
phase" (because, after a roaming, once A sends out its OGM, all the changes are
committed and the node is considered not to be in the roaming state anymore)
and it will match the ttvn carried by the packet. Therefore there is no reason
for A to try to alter the packet's route, thus dropping the packet because the
destination client is not there anymore.
However, C is well aware that it's routing information towards the client X is
outdated as it received an OGM from A saying that the client roamed away.
Thanks to this detail, this patch introduces a small change in behaviour: as
long as C is in the state of not knowing the new location of client X it will
forward the traffic to its last known location using ttvn-1 of the destination.
By using an older ttvn node A will be forced to re-route the packet.
Intermediate nodes are also allowed to update the packet's destination as long
as they have the information about the client's new location.

Most PCI implementations perform simple root bus scanning. Rather than
having each group of platforms provide a duplicated bus scan function,
provide the PCI configuration ops structure via the hw_pci structure,
and call the root bus scanning function from core ARM PCI code.

Most PCI implementations use the standard PCI swizzle function, which
handles the well defined behaviour of PCI-to-PCI bridges which can be
found on cards (eg, four port ethernet cards.)
Rather than having almost every platform specify the standard swizzle
function, make this the default when no swizzle function is supplied.
Therefore, a swizzle function only needs to be provided when there is
something exceptional which needs to be handled.
This gets rid of the swizzle initializer from 47 files, and leaves us
with just two platforms specifying a swizzle function: ARM Integrator
and Chalice CATS.

This is at odds with the documentation in the file; it says pin 1 on
slots 24,25,26,27 map to IRQs 27,28,29,30, but the function will always
be entered with slot=0 due to the lack of swizzle function. Fix this
function to behave as the comments say, and use the standard PCI
swizzle.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
The Integrator swizzle function is almost the same as the standard PCI
swizzle, except for an initial check for pin = 0. Make the integrator
swizzle function a wrapper around the standard PCI swizzle function so
we preseve this behaviour while using common code.
