All uses of list_for_each_rcu() can be profitably replaced by the

Instead of assigning values for the struct cpu_reg's at runtime,
we already know these values at compile time. Therefore, we can use
designated initializers, to initialize these structures and not have
to incur this assignment cost at run-time.

The rx_offset field is set to a constant value and initialized
only once. By replacing all references to the rx_offset field,
we can eliminate rx_offset from the bnx2 structure. This will
save 4 bytes for every bnx2 instance.

Andy Gospodarek <andy@greyhouse.net> found that netconsole would
panic when resetting bnx2 devices.
>From Andy:
"The issue is the bnx2_set_link in bnx2_init_nic will print a link-status
message before we are fully initialized and ready to start polling.
Polling is currently disabled in this state, but since the
__LINK_STATE_RX_SCHED is overloaded to not only try and disable polling
but also to make the system aware there is something waiting to be
polled, we really have to fix this in drivers.
The problematic call is the one to netif_rx_complete as it tries to
remove an entry from the poll_list when there isn't one."
While this netconsole problem should be fixed separately, we really
should not reset the PHY when changing ring sizes, MTU, or other
similar settings. The PHY reset causes several seconds of unnecessary
link disruptions.

adds various options to cifs_show_options
(displayed when you cat /proc/mounts with a cifs mount). I limited
the new ones to values that are associated with the mount with the
exception of "seal" (which is a per tree connection property, but I
thought was important enough to show through).
Eventually cifs's parse_mount_options also needs to
be rewritten to use the match_token API but that would be a big enough
change that I would prefer that changing parse_mount_options wait
until next release.

The mthca driver returns the maximum number of scatter/gather entries
returned by the firmware as the max_sge value when device properties
are queried. However, the firmware also reports a limit on the
maximum descriptor size allowed, and because mthca takes into account
the worst case send request overhead when checking whether to allow a
QP to be created, the largest number of scatter/gather entries that
can be used with mthca may be limited by the maximum descriptor size
rather than just by the actual s/g entry limit.
This means that applications cannot actually create QPs with
max_send_sge equal to the limit returned by ib_query_device(). Fix
this by checking if the maximum descriptor size imposes a lower limit
and if so returning that lower limit.

Parent _can_ be a clone task, contrary to the comment. Moreover,
more files could be opened while we allocate a copy, in which case
we end up copying only part into new descriptor table. Since what
we get _is_ affected by all changes in the old range, we can get
rather weird effects - e.g.
dup2(0, 1024); close(0);
in parallel with fork() resulting in child that sees the effect of
close(), but not that of dup2() done just before that close().
What we need is to recalculate the open_count after having reacquired
->file_lock and if external fdtable we'd just allocated is too small for
it, free the sucker and redo allocation.

Since commit e38bad4766
mac80211: make ieee80211_iterate_active_interfaces not need rtnl
rt2500usb and rt73usb broke down due to attempting register access
in atomic context (which is not possible for USB hardware).
This patch restores ieee80211_iterate_active_interfaces() to use RTNL lock,
and provides the non-RTNL version under a new name:
ieee80211_iterate_active_interfaces_atomic()
So far only rt2x00 uses ieee80211_iterate_active_interfaces(), and those
drivers require the RTNL version of ieee80211_iterate_active_interfaces().
Since they already call that function directly, this patch will automatically
fix the USB rt2x00 drivers.

NFSv3 get_sb operations call into the LSM layer to set security options passed
from userspace. NFSv4 hooks were not originally added since it was reasonably
late in the merge window and NFSv3 was the only thing that had regressed (v4
has never supported any LSM options)
This patch makes NFSv4 call into the LSM to set security options rather than
just blindly dropping them with no notice to the user as happens today. This
patch was tested in a simple NFSv4 environment with the context= option and
appeared to work as expected.

If decode_compound_hdr_arg() returns a resource error, then we cannot
proceed to process the callback. Return a 'GARBAGE_ARGS' rpc-level error to
the caller instead.
If, however, the minor version field is incorrect, then we need to
propagate the resulting NFS4ERR_MINOR_VERS_MISMATCH error back as the
compound status field (setting the nops field to 0).
Finally, if encode_compound_hdr_res() returns an error, we need to return
an RPC_SYSTEM_ERR to the caller.

Both the 'noac' and 'actimeo=0' mount options should ensure that attributes
are not cached, however a bug in nfs_attribute_timeout() means that
currently, the attributes may in fact get cached for up to one jiffy. This
has been seen to cause corruption in some applications.
The reason for the bug is that the time_in_range() test returns 'true' as
long as the current time lies between nfsi->read_cache_jiffies and
nfsi->read_cache_jiffies + nfsi->attrtimeo. In other words, if jiffies
equals nfsi->read_cache_jiffies, then we still cache the attribute data.
