[SCSI] Fix async scanning double-add problems

Stress-testing and some thought has revealed some places where
asynchronous scanning needs some more attention to locking.

 - Since async_scan is a bit, we need to hold the host_lock while
   modifying it to prevent races against other CPUs modifying the word
   that bit is in.  This is probably a theoretical race for the moment,
   but other patches may change that.
 - The async_scan bit means not only that this host is being scanned
   asynchronously, but that all the devices attached to this host are not
   yet added to sysfs.  So we must ensure that this bit is always in sync.
   I've chosen to do this with the scan_mutex since it's already acquired
   in most of the right places.
 - If the host changes state to deleted while we're in the middle of
   a scan, we'll end up with some devices on the host's list which must
   be deleted.  Add a check to scsi_sysfs_add_devices() to ensure the
   host is still running.
 - To avoid the async_scan bit being protected by three locks, the
   async_scan_lock now only protects the scanning_list.

[SCSI] tgt: add I_T nexus support

tgt uses scsi_host as I_T nexus. This works for ibmvstgt because it
creates one scsi_host for one initiator. However, other target drivers
don't work like that.

This adds I_T nexus support, which enable one scsi_host to handle
multiple initiators. New scsi_tgt_it_nexus_create/destroy functions
are expected be called transport classes. For example, ibmvstgt
creates an initiator remote port, then the srp transport calls
tgt_it_nexus_create. tgt doesn't manages I_T nexus, instead it tells
tgtd, user-space daemon, to create a new I_T nexus.

On the receiving the response from tgtd, tgt calls
shost->transportt->it_nexus_response. transports should notify a
lld. The srp transport uses it_nexus_response callback in
srp_function_template to do that.

[GFS2] soft lockup detected in databuf_lo_before_commit

This is part 2 of the patch for bug #245832, part 1 of which is already
in the git tree.

The problem was that sdp->sd_log_num_databuf was not always being
protected by the gfs2_log_lock spinlock, but the sd_log_le_databuf
(which it is supposed to reflect) was protected.  That meant there
was a timing window during which gfs2_log_flush called
databuf_lo_before_commit and the count didn't match what was
really on the linked list in that window.  So when it ran out of
items on the linked list, it decremented total_dbuf from 0 to -1 and
thus never left the "while(total_dbuf)" loop.

The solution is to protect the variable sdp->sd_log_num_databuf so
that the value will always match the contents of the linked list,
and therefore the number will never go negative, and therefore, the
loop will be exited properly.

[DLM] fix basts for granted PR waiting CW

Fix a long standing bug where a blocking callback would be missed
when there's a granted lock in PR mode and waiting locks in both
PR and CW modes (and the PR lock was added to the waiting queue
before the CW lock).  The logic simply compared the numerical values
of the modes to determine if a blocking callback was required, but in
the one case of PR and CW, the lower valued CW mode blocks the higher
valued PR mode.  We just need to add a special check for this PR/CW
case in the tests that decide when a blocking callback is needed.

[IPVS]: Use IP_VS_WAIT_WHILE when encessary.

For architectures that don't have a volatile atomic_ts constructs like
while (atomic_read(&something)); might result in endless loops since a
barrier() is missing which forces the compiler to generate code that

[NET]: Share correct feature code between bridging and bonding

http://bugzilla.kernel.org/show_bug.cgi?id=8797 shows that the
bonding driver may produce bogus combinations of the checksum
flags and SG/TSO.

For example, if you bond devices with NETIF_F_HW_CSUM and
NETIF_F_IP_CSUM you'll end up with a bonding device that
has neither flag set.  If both have TSO then this produces
an illegal combination.

The bridge device on the other hand has the correct code to
deal with this.

In fact, the same code can be used for both.  So this patch
moves that logic into net/core/dev.c and uses it for both
bonding and bridging.

In the process I've made small adjustments such as only
setting GSO_ROBUST if at least one constituent device
supports it.

[IPCONFIG]: ip_auto_config fix

The following commandline:

makes ip_auto_config fall back to DHCP and complain "IP-Config: Incomplete
network configuration information." depending on if CONFIG_IP_PNP_DHCP is
set or not.

The only way I can make ip_auto_config accept my IP config is to add an
entry for the server IP:

ip=192.168.1.10:192.168.1.15::255.255.255.0:localhost.localdomain:eth1:off

I think this is a bug since I am not using a NFS root FS.

The following patch fixes the above problem.

From: Andrew Morton <akpm@linux-foundation.org>

Davem said (in February!):

  Well, first of all the change in question is not in 2.4.x either.  I just
  checked the current 2.4.x GIT tree and the test is exactly:

if (ic_myaddr == INADDR_NONE ||
#ifdef CONFIG_ROOT_NFS
    (MAJOR(ROOT_DEV) == UNNAMED_MAJOR
     && root_server_addr == INADDR_NONE
     && ic_servaddr == INADDR_NONE) ||
#endif
    ic_first_dev->next) {

  which matches 2.6.x

  I even checked 2.4.x when it was branched for 2.5.x and the test was the
  same at the point in time too.

  Looking at the proposed change a bit it appears that it is probably
  correct, as it's trying to check that ROOT_DEV is nfs root.  But if it is
  correct then the UNNAMED_MAJOR comparison in the same code block should be
  removed as it becomes superfluous.

  I'm happy to apply this patch with that modification made.

Do not replace whole memcpy in apply alternatives

apply_alternatives uses memcpy() to apply alternatives.  Which has the
unfortunate effect that while applying memcpy alternative to memcpy
itself it tries to overwrite itself with nops - which causes #UD fault
as it overwrites half of an instruction in copy loop, and from this
point on only possible outcome is triplefault and reboot.

So let's overwrite only first two instructions of memcpy - as long as
the main memcpy loop is not in first two bytes it will work fine.

ACPI: thermal: add DMI hooks to handle AOpen's broken Award BIOS

Use DMI to:
1. enable polling (BIOS thermal events are broken)
2. disable active trip points (BIOS fan control is broken)
3. disable passive trip point (BIOS hard-codes it too low)

The actual temperature reading does work,
and with the aid of polling, the critical
trip point should work too.
