Christoph Hellwig 0c33b27deb [SCSI] fusion SAS support (mptsas driver)
Adds the actual mptsas driver, based upon the LSI driver with new work
for SAS transport class integration from Eric Moore and me.

This obviously depends on the SAS transport class.

Christoph Hellwig 82ffb67164 [SCSI] fusion core changes for SAS support
- various bits for SAS support from the LSI driver.
 - use the device private data for the fusion target private data.
   this should be using the midlayer target data framework, but we
   can't move over to that until fusion has been switched to the
   generic DV code
 - use target ID and channel from the fusion target private data,
   because those in scsi_device will be different for mptsas

James Bottomley 3ed7a4704b [SCSI] Fix thread termination for the SCSI error handle
From: 	Alan Stern <stern@rowland.harvard.edu>

This patch (as561) fixes the error handler's thread-exit code.  The
kthread_stop call won't wake the thread from a down_interruptible, so
the patch gets rid of the semaphore and simply does

        set_current_state(TASK_INTERRUPTIBLE);

James Bottomley 939647ee30 [SCSI] fix oops on usb storage device disconnect
We fix the oops by enforcing the host state model.  There have also
been two extra states added: SHOST_CANCEL_RECOVERY and
SHOST_DEL_RECOVERY so we can take the model through host removal while
the recovery thread is active.

Alan Stern a64358db12 [SCSI] SCSI scanning and removal fixes
This patch (as545) fixes the list traversals in __scsi_remove_target and
scsi_forget_host.  In each case the existing code list_for_each_entry_safe
in an _unsafe_ manner, because the list was not protected from outside
modification while the iteration was running.

The new scsi_forget_host routine takes the moderately controversial step
of iterating over devices for removal rather than iterating over targets.
This makes more sense to me because the current scheme treats targets as
second-class citizens, created and removed on demand, rather than as
objects corresponding to actual hardware.  (Also I couldn't figure out any
safe way to iterate over the target list, since it's not so easy to tell
when a target has already been removed.)

Andreas Herrmann 1832a5862f [SCSI] change port speed definitions for scsi_transport_fc
obviously FC Port Speeds in scsi_transport_fc.h are defined according
to FC-HBA:

#define FC_PORTSPEED_1GBIT              1
#define FC_PORTSPEED_2GBIT              2
#define FC_PORTSPEED_10GBIT             4
#define FC_PORTSPEED_4GBIT              8

Problem is, whoever invented FC-HBA did not care about FC-FS or
FC-GS-x. Following FC-FS/FC-GS-x defintions of port speeds would look
like:

1 GBit: 0x0001
2 GBit: 0x0002
4 GBit: 0x0004
10GBit: 0x0008

(and new in FC-LS:
8 Gbit: 0x0010
16GBit: 0x0020)

I really appreciate if scsi_transport_fc.h would define port speeds
according to FC-GS-x/FC-FS. Thus mapping of port speed capabilities to
values defined in scsi_transport_fc.h can be avoided in the LLDD.

Attached is a patch to change the definitions.

OK, my fault.  Your fix is almost correct .. I was going to do this
eventually, honest, because there's no need to unprep and reprep a
command that comes in through scsi_queue_insert().

However, I decided to leave it in to exercise the scsi_unprep_request()
path just to make sure it was working.  What's happening, I think, is
that we also use this path for retries.  Since we kill and reget the
command each time, the retries decrement is never seen, so we're
retrying forever.

James Bottomley a89f29f6ea [SCSI] aic7xxx: move to dma_get_required_mask() and correct 39 bit assumptions
This patch moves aic7xxx over to the dma_get_required_mask() API and
dumps its open coded memory check.

It also appears from this bug:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=167049

That 39 bit addressing doesn't work on older cards.  I surmise that the
AHC_LARGE_SCBS flag is the one that marks cards capable of using 39 bit
addressing, so I also folded that check into the code.

Ralf Baechle e21ce8c7c0 [NETROM]: Implement G8PZT Circuit reset for NET/ROM
NET/ROM is lacking a connection reset like TCP's RST flag which at times
may result in a connecting having to slowly timing out instead of just being
reset.  An earlier attempt to reset the connection by sending a
NR_CONNACK | NR_CHOKE_FLAG transport was inacceptable as it did result in
crashes of BPQ systems.  An alternative approach of introducing a new
transport type 7 (NR_RESET) has be implemented several years ago in
Paula Jayne Dowie G8PZT's Xrouter.

Implement NR_RESET for Linux's NET/ROM but like any messing with the state
engine consider this experimental for now and thus control it by a sysctl
(net.netrom.reset) which for the time being defaults to off.
