69f2a08047 Drop three omap3 legacy board-*.c files
We want to get omap3 moved over to device tree only based booting.
 
 These three board-*.c files seem to be inactive, so let's attempt
 to drop them now rather than later. With these dropped, we have
 omap3 device tree conversion status in a known state. Then we know
 that we have .dts support for the remaining omap3 board-*.c files,
 or it's being worked on.
 
 By dropping these files now, we can simply revert them if really
 needed for the next few merge cycles if we run into suprises.
 Reverting things later on will not be so easily done.

342f346af1 Few omap2plus_defconfig updates to add commonly used drivers as
loadable modules.
 
 Note that I'll do patches for armv7_defconfig for these at some
 point too once we're happy with omap2plus_defconfig to avoid
 extra churn on the defconfig files.

d30323f810 usb: musb: dsps: fix build on i386 when COMPILE_TEST is set
Commit 3e457371f4 ("usb: musb: Fix fifo reads for dm816x with musb_dsps")
fixed a USB error on dm816x, but introduced a new build error on i386
when COMPILE_TEST is set:

drivers/usb/musb/musb_dsps.c: In function ‘dsps_read_fifo32’:
drivers/usb/musb/musb_dsps.c:624:3: error: implicit declaration of function
‘readsl’ [-Werror=implicit-function-declaration]
readsl(fifo, dst, len >> 2);

Let's fix this by using ioread32_rep() instead of readsl() as that's
more portable.

Fixes: 3e457371f4 ("usb: musb: Fix fifo reads for dm816x with musb_dsps")

2e7056c433 jhash: Update jhash_[321]words functions to use correct initval
Looking over the implementation for jhash2 and comparing it to jhash_3words
I realized that the two hashes were in fact very different.  Doing a bit of
digging led me to "The new jhash implementation" in which lookup2 was
supposed to have been replaced with lookup3.

In reviewing the patch I noticed that jhash2 had originally initialized a
and b to JHASH_GOLDENRATIO and c to initval, but after the patch a, b, and
c were initialized to initval + (length << 2) + JHASH_INITVAL.  However the
changes in jhash_3words simply replaced the initialization of a and b with
JHASH_INITVAL.

This change corrects what I believe was an oversight so that a, b, and c in
jhash_3words all have the same value added consisting of initval + (length
<< 2) + JHASH_INITVAL so that jhash2 and jhash_3words will now produce the
same hash result given the same inputs.

Intel Wired LAN Driver Updates 2015-04-03

This series contains updates to i40e and i40evf only.

Anjali provides a fix for verifying outer UDP receive checksum.  Also
adds helpful information to display when figuring out the cause of
HMC errors.

Mitch provides a fix to prevent a malicious or buggy VF driver from
sending an invalid index into the VSI array which could panic the host.
Cleans up the code where a function was moved, but the message did
not follow.  Adds protection to the VLAN filter list, same as the
MAC filter list, to protect from corruption if the watchdog happens
to run at the same time as a VLAN filter is being added/deleted.

Jesse changes several memcpy() statements to struct assignments which
are type safe and preferable.  Fixed a bug when skb allocation fails,
where we should not continue using the skb pointer.  Also fixed a void
function in FCoE which should not be returning anything.

Greg fixes both i40e and i40evf to set the Ethernet protocol correctly
when transmit VLAN offloads are disabled.

Shannon fixes up VLAN messages when ports are added or removed, which
were giving bogus index info.  Also aligned the message text style
with other messages in the driver.

576b7cd2f6 netns: don't allocate an id for dead netns
First, let's explain the problem.
Suppose you have an ipip interface that stands in the netns foo and its link
part in the netns bar (so the netns bar has an nsid into the netns foo).
Now, you remove the netns bar:
 - the bar nsid into the netns foo is removed
 - the netns exit method of ipip is called, thus our ipip iface is removed:
   => a netlink message is built in the netns foo to advertise this deletion
   => this netlink message requests an nsid for bar, thus a new nsid is
      allocated for bar and never removed.

This patch adds a check in peernet2id() so that an id cannot be allocated for
a netns which is currently destroyed.

ipv4: coding style - comparisons with NULL

Per the suggestion of Joe Perches, attached is a patch which aligns the
coding style in ipv4 for comparisons with NULL.

The code uses multiple different styles when comparing with NULL (I.e.
x == NULL and !x as well as x != NULL and x). Generally the latter form
is preferred in netdev and so this changes aligns the code to this style.

2bfd4d1f8c ftracetest: Do not use usleep directly
The usleep is only provided on distros from Redhat so running ftracetest
on other distro resulted in failures due to the missing usleep.

The reason of using [u]sleep in the test was to generate (scheduler)
events.  It can be done various ways like this:

yield() {  ping localhost -c 1 || sleep .001 || usleep 1 || sleep 1; }

e12fb97222 ext4: make fsync to sync parent dir in no-journal for real this time
Previously commit 14ece1028b added a
support for for syncing parent directory of newly created inodes to
make sure that the inode is not lost after a power failure in
no-journal mode.

However this does not work in majority of cases, namely:
 - if the directory has inline data
 - if the directory is already indexed
 - if the directory already has at least one block and:
	- the new entry fits into it
	- or we've successfully converted it to indexed

So in those cases we might lose the inode entirely even after fsync in
the no-journal mode. This also includes ext2 default mode obviously.

I've noticed this while running xfstest generic/321 and even though the
test should fail (we need to run fsck after a crash in no-journal mode)
I could not find a newly created entries even when if it was fsynced
before.

Fix this by adjusting the ext4_add_entry() successful exit paths to set
the inode EXT4_STATE_NEWENTRY so that fsync has the chance to fsync the
parent directory as well.
