This patch removes redundant code where ever logical volumes are added or
removed. It adds 3 new functions that are called instead of having the same
code spread throughout the driver. It also removes the cciss_getgeometry
function.
The patch is fairly complex but we haven't figured out how to make it any
simpler and still do everything that needs to be done. Some of the
complexity comes from having to special case booting from cciss. Otherwise
the gendisk doesn't get added in time and the switchroot will fail.

This patch makes the rebuild_lun_table smart enough to not rip a logical
volume out from under the OS. Without this fix if a customer is running
hpacucli to monitor their storage the driver will blindly remove and re-add
the disks whenever the utility calls the CCISS_REGNEWD ioctl. Unfortunately,
both hpacucli and ACUXE call the ioctl repeatedly. Customers have reported
IO coming to a standstill. Calling the ioctl is the problem, this patch is
the fix.

This re-introduces commit 2b14290078,
which was reverted due to the regression it caused by commit
fca082c9f1.
That regression was not root-caused by the original commit, it was just
uncovered by it, and the real fix was done by Alan Stern in commit
580da34847 ("Fix USB storage hang on
command abort").
We can thus re-introduce the change that was confirmed by Alan Jenkins
to be still required by his odd card reader.

From: Stephen Hemminger <shemminger@vyatta.com>
Based upon original patch by Herbert Xu, which contained
the following problem description:
--------------------
When the forward delay is set to zero, we still delay the setting
of the forwarding state by one or possibly two timers depending
on whether STP is enabled. This could either turn out to be
instantaneous, or horribly slow depending on the load of the
machine.
As there is nothing preventing us from enabling forwarding straight
away, this patch eliminates this potential delay by executing the
code directly if the forward delay is zero.
The effect of this problem is that immediately after the carrier
comes on a port, the bridge will drop all packets received from
that port until it enters forwarding mode, thus causing unnecessary
packet loss.
Note that this patch doesn't fully remove the delay due to the
link watcher. We should also check the carrier state when we
are about to drop an incoming packet because the port is disabled.
But that's for another patch.
--------------------
This version of the fix takes a different approach, in that
it just does the state change directly.

Hugh adds: in fact, none of find_vma_prepare's callers use those values
when a vma is found to be already covering addr, it's either an error or
an occasion to munmap and repeat. Okay, let's quieten the compiler (but I
would prefer it if pprev, rb_link and rb_parent were meaningful in that
case, rather than whatever's in them from descending the tree).

get_order() takes byte-sized input, not a page-granular one.
Irrespective of this fix I'm inclined to believe that this doesn't work
right anyway - bitmap_allocate_region() has an implicit assumption of
'pos' being suitable for 'order', which this function doesn't seem to
enforce (and since it's being called with a byte-granular value there's no
reason to believe that the callers would make sure device_addr is passed
accordingly - it's also not documented that way).

I have a new PCI-E radeon RV380 series card (PCI device ID 5b64) that
hangs in my sparc64 boxes when the init scripts set the font. The problem
goes away if I disable acceleration.
I haven't figured out that bug yet, but along the way I found some
corrections to make based upon some auditing.
1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver
and the XORG video driver differ. I've made the kernel
match what XORG is using.
2) In radeonfb_engine_reset() we have top-level code structure
that roughly looks like:
if (family is 300, 350, or V350)
do this;
else
do that;
...
if (family is NOT 300, OR
family is NOT 350, OR
family is NOT V350)
do another thing;
this last conditional makes no sense, is always true,
and obviously was likely meant to be "family is NOT
300, 350, or V350". So I've made the code match the
intent.
