When p9pdu_readf() is called with "s" attribute, it allocates a pointer that
will store a string. In p9dirent_read(), this pointer is not being released,
leading to out of memory errors.
This patch releases this pointer after string is copyed to dirent->d_name.

So when enabled, it enables internal-MAC loopback.

Michał Mirosław's patch (http://patchwork.ozlabs.org/patch/94421/) fixes the
issue (http://patchwork.ozlabs.org/patch/94188/) about not populating FCoE related
flags correctly on vlan devices. However, only NETIF_F_FCOE_CRC is part of the
NETIF_F_ALL_TX_OFFLOADS right now, where weed NETIF_F_FCOE_MTU and NETIF_F_FSO
as well.
Therefore, add NETIF_F_ALL_FCOE to indicate feature flags used by FCoE TX offloads.
These include NETIF_F_FCOE_CRC, NETIF_F_FCOE_MTU, and NETIF_F_FSO and add them to
be part of NETIF_F_ALL_TX_OFFLOADS. This would eventually make sure all FCoE needed
flags are populated properly to vlan devices.

Fix VLAN features propagation for devices which change vlan_features.
For this to work, driver needs to make sure netdev_features_changed()
gets called after the change (it is e.g. after ndo_set_features()).
Side effect is that a user might request features that will never
be enabled on a VLAN device.

When removing last vlan from a device, garp_uninit_applicant() calls
synchronize_rcu() to make sure no user can still manipulate struct
garp_applicant before we free it.
Use call_rcu() instead, as a step to further net_device dismantle
optimizations.
Add the temporary garp_cleanup_module() function to make sure no pending
call_rcu() are left at module unload time [ this will be removed when
kfree_rcu() is available ]

This is a fix for the SGI Altix-UV Broadcast Assist Unit code,
which is used for TLB flushing.
Certain hardware configurations (that customers are ordering)
cause nasids (numa address space id's) to be non-consecutive.
Specifically, once you have more than 4 blades in a IRU
(Individual Rack Unit - or 1/2 rack) but less than the maximum
of 16, the nasid numbering becomes non-consecutive. This
currently results in a 'catastrophic error' (CATERR) detected by
the firmware during OS boot. The BAU is generating an 'INTD'
request that is targeting a non-existent nasid value. Such
configurations may also occur when a blade is configured off
because of hardware errors. (There is one UV hub per blade.)
This patch is required to support such configurations.
The problem with the tlb_uv.c code is that is using the
consecutive hub numbers as indices to the BAU distribution bit
map. These are simply the ordinal position of the hub or blade
within its partition. It should be using physical node numbers
(pnodes), which correspond to the physical nasid values. Use of
the hub number only works as long as the nasids in the partition
are consecutive and increase with a stride of 1.
This patch changes the index to be the pnode number, thus
allowing nasids to be non-consecutive.
It also provides a table in local memory for each cpu to
translate target cpu number to target pnode and nasid.
And it improves naming to properly reflect 'node' and 'uvhub'
versus 'nasid'.

Avoid multiple queues when MSI or MSI-X not available
Limit number of Tx queues to 1 if MSI/MSI-X support is not configured in
the kernel. This will make number of tx and rx queues equal when MSI/X
is not configured thus providing better performance.

While trying to remove useless synchronize_rcu() calls, I found l2tp is
indeed incorrectly using two of such calls, but also bumps tunnel
refcount after list insertion.
tunnel refcount must be incremented before being made publically visible
by rcu readers.
This fix can be applied to 2.6.35+ and might need a backport for older
kernels, since things were shuffled in commit fd558d186d
(l2tp: Split pppol2tp patch into separate l2tp and ppp parts)
