6c78dcbd47 [VLAN]: Fix promiscous/allmulti synchronization races
The set_multicast_list function may be called without holding the rtnl
mutex, resulting in races when changing the underlying device's promiscous
and allmulti state. Use the change_rx_mode hook, which is always invoked
under the rtnl.

a0a400d79e [NET]: dev_mcast: add multicast list synchronization helpers
The method drivers currently use to synchronize multicast lists is not
very pretty:

- walk the multicast list
- search each entry on a copy of the previous list
- if new add to lower device
- walk the copy of the previous list
- search each entry on the current list
- if removed delete from lower device
- copy entire list

This patch adds a new field to struct dev_addr_list to store the
synchronization state and adds two helper functions for synchronization
and cleanup.

24023451c8 [NET]: Add net_device change_rx_mode callback
Currently the set_multicast_list (and set_rx_mode) callbacks are
responsible for configuring the device according to the IFF_PROMISC,
IFF_MULTICAST and IFF_ALLMULTI flags and the mc_list (and uc_list in
case of set_rx_mode).

These callbacks can be invoked from BH context without the rtnl_mutex
by dev_mc_add/dev_mc_delete, which makes reading the device flags and
promiscous/allmulti count racy. For real hardware drivers that just
commit all changes to the hardware this is not a real problem since
the stack guarantees to call them for every change, so at least the
final call will not race and commit the correct configuration to the
hardware.

For software devices that want to synchronize promiscous and multicast
state to an underlying device however this can cause corruption of the
underlying device's flags or promisc/allmulti counts.

When the software device is concurrently put in promiscous or allmulti
mode while set_multicast_list is invoked from bottem half context, the
device might synchronize the change to the underlying device without
holding the rtnl_mutex, which races with concurrent changes to the
underlying device.

Add a dev->change_rx_flags hook that is invoked when any of the flags
that affect rx filtering change (under the rtnl_mutex), which allows
drivers to perform synchronization immediately and only synchronize
the address lists in set_multicast_list/set_rx_mode.

e6c9116d1d [RFKILL]: fix net/rfkill/rfkill-input.c bug on 64-bit systems
Subject: [patch] net/input: fix net/rfkill/rfkill-input.c bug on 64-bit systems

this recent commit:

 commit cf4328cd94
 Author: Ivo van Doorn <IvDoorn@gmail.com>
 Date:   Mon May 7 00:34:20 2007 -0700

     [NET]: rfkill: add support for input key to control wireless radio

added this 64-bit bug:

        ....
	unsigned int flags;
 
 	spin_lock_irqsave(&task->lock, flags);
        ....

irq 'flags' must be unsigned long, not unsigned int. The -rt tree has 
strict checks about this on 64-bit so this triggered a build failure.

Using the new POSIX unlink, which Samba has supported for a few

7689e82efd [SCSI] don't build scsi_dma_{map,unmap} for !HAS_DMA
With

 dma-mapping-prevent-dma-dependent-code-from-linking-on.patch

scsi fails to build on !HAS_DMA architectures:

: undefined reference to `dma_map_sg'
drivers/built-in.o(.text+0x20b5c): In function `scsi_dma_unmap':
: undefined reference to `dma_unmap_sg'

I split those functions out into a new file. Builds on s390 and i386.

Move scsi_dma_{map,unmap} into scsi_lib_dma.c which is only build if
HAS_DMA is set.

c59fd9ebc4 [SCSI] lpfc: fix NPIV mapping problems
This patch uses dma_map_sg with phba->pcidev->dev instead of
scsi_dma_map.

scsi_dma_map doesn't work for NPIV since fc_vport->dev isn't fully
initialized. check_addr() in arch/x86_64/kernel/pci-nommu.c leads to
the crash since dev->dma_mask is NULL.
