tmpfs: fix XATTR N overriding POSIX_ACL Y
Choosing TMPFS_XATTR default N was switching off TMPFS_POSIX_ACL,

Make TMPFS_POSIX_ACL select TMPFS_XATTR (and depend upon TMPFS),

commit

introduced a CONFIG_HIGHRES_TIMERS (should be CONFIG_HIGH_RES_TIMERS)
typo, which caused applications depending on CLOCK_REALTIME timers to
become sluggy due to the fact that the time base of the realtime
timers was not updated when the wall clock time was set.
This causes anything from 100% CPU use for some applications to odd

It occurs because we are able to change the slave configuarion of a bond while
the bond interface is down. The bonding driver initializes some data structures
only after its ndo_open routine is called. Among them is the initalization of
the alb tx and rx hash locks. So if we add or remove a slave without first
opening the bond master device, we run the risk of trying to lock/unlock a
spinlock that has garbage for data in it, which results in our above softlock.
Note that sometimes this works, because in many cases an unlocked spinlock has
the raw_lock parameter initialized to zero (meaning that the kzalloc of the
net_device private data is equivalent to calling spin_lock_init), but thats not
true in all cases, and we aren't guaranteed that condition, so we need to pass
the relevant spinlocks through the spin_lock_init function.
Fix it by moving the spin_lock_init calls for the tx and rx hashtable locks to
the ndo_init path, so they are ready for use by the bond_store_slaves path.
Change notes:
v2) Based on conversation with Jay and Nicolas it seems that the ability to
enslave devices while the bond master is down should be safe to do. As such
this is an outlier bug, and so instead we'll just initalize the errant spinlocks
in the init path rather than the open path, solving the problem. We'll also
remove the warnings about the bond being down during enslave operations, since
it should be safe
v3) Fix spelling error

isdn: netjet - blacklist Digium TDM400P
[2nd try ... 1st attempt didn't make it to netdev mailing list]
A quick google search reveals that people with this card are blacklisting it
in the initramfs and in the module blacklist based on a statement that it
is unsupported. Since the older Digium is also unsupported I'm pretty
confident that this newer card is also not supported.

The Asterisk Voice Card, DIGIUM TDM400P is unsupported by the netjet driver.
Blacklist it like the Digium X100P/X101P card.

via-velocity: don't annotate MAC registers as packed
On ARM, memory accesses through packed pointers behave in unexpected
ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163
for discussion.
In this particular case, 32-bit I/O registers are accessed bytewise,
causing incorrect setting of the DMA address registers which in turn
leads to an error interrupt storm that brings the system to a halt.
Since the mac_regs structure does not need any packing anyway, this patch
simply removes the attribute to fix the issue.

The abituguru drivers are only built on X86, where DMI support is now

following gains:
* Robustness and safety. Detection of these devices is weak and uses
non-standard methods, it should really be limited to Abit boards
unless the user explicitly asks otherwise.
* Code simplicity. The code is easier to read without ifdefs.
* Better build testing coverage. Now there's only one way to build the
