Freescale eSDHC controller has the special order for
the HOST version register. that is not same as the other's
registers. The address of HOSTVER in spec is 0xFE, and
we need use the in_be16(0xFE) to access it, not in_be16(0xFC).

Especially with Sandisk SDHC cards, the second SWITCH command was failing
with a timeout and the card was not recognized at all.  However if the
system was busy, or debugging was enabled, or a udelay(100) was inserted
before the second SWITCH command in the core code, then the timing was
so that the card started to work.

With some unusual block sizes, the data FIFO status doesn't indicate a
"empty" state right away when the data transfer is done.  Queuing
another data transfer in that condition results in a transfer timeout.

The empty FIFO bit eventually get set by itself in less than 50 usecs
when it is not set right away. So let's just poll for that bit before
configuring the controller with a new data transfer.

Empirical evidences show that this is causing far more problems than it
solves when this mode is enabled in the host hardware.  Amongst those
cards that are known to be non functional when this bit is set are:

	A-Data "Speedy" 2GB SD card
	Kodak 512MB SD card
	Ativa 1GB MicroSD card
	Marvell 8688 (WIFI/Bluetooth) SDIO card

Since those cards do work on other host controllers which do honnor the
hs timing, the issue must be with this particular host hardware.

net_cls: fix unconfigured struct tcf_proto keeps chaining and avoid kernel panic when we use cls_cgroup

This patch fixes a bug which unconfigured struct tcf_proto keeps
chaining in tc_ctl_tfilter(), and avoids kernel panic in
cls_cgroup_classify() when we use cls_cgroup.

When we execute 'tc filter add', tcf_proto is allocated, initialized
by classifier's init(), and chained.  After it's chained,
tc_ctl_tfilter() calls classifier's change().  When classifier's
change() fails, tc_ctl_tfilter() does not free and keeps tcf_proto.

In addition, cls_cgroup is initialized in change() not in init().  It
accesses unconfigured struct tcf_proto which is chained before
change(), then hits Oops.

	Patch to fix bad length checking in e1000.  E1000 by default does two
things:

1) Spans rx descriptors for packets that don't fit into 1 skb on recieve
2) Strips the crc from a frame by subtracting 4 bytes from the length prior to
doing an skb_put

Since the e1000 driver isn't written to support receiving packets that span
multiple rx buffers, it checks the End of Packet bit of every frame, and
discards it if its not set.  This places us in a situation where, if we have a
spanning packet, the first part is discarded, but the second part is not (since
it is the end of packet, and it passes the EOP bit test).  If the second part of
the frame is small (4 bytes or less), we subtract 4 from it to remove its crc,
underflow the length, and wind up in skb_over_panic, when we try to skb_put a
huge number of bytes into the skb.  This amounts to a remote DOS attack through
careful selection of frame size in relation to interface MTU.  The fix for this
is already in the e1000e driver, as well as the e1000 sourceforge driver, but no
one ever pushed it to e1000.  This is lifted straight from e1000e, and prevents
small frames from causing the underflow described above

Add a phy_power_down parameter to forcedeth: set to 1 to power down the
phy and disable the link when an interface goes down; set to 0 to always
leave the phy powered up.

The phy power state persists across reboots; Windows, some BIOSes, and
older versions of Linux don't bother to power up the phy again, forcing
users to remove all power to get the interface working (see
http://bugzilla.kernel.org/show_bug.cgi?id=13072).  Leaving the phy
powered on is the safest default behavior.  Users accustomed to seeing
the link state reflect the interface state and/or wanting to minimize
power consumption can set phy_power_down=1 if compatibility with other
OSes is not an issue.

In the case where growing a filesystem would leave the last AG
too small, the fixup code has an overflow in the calculation
of the new size with one fewer ag, because "nagcount" is a 32

this causes a problem resulting in an EINVAL return from growfs:

Regreesion from commit ef8f7fc5, which rearranged the code in
xfs_swap_extents() leading to double unlock of xfs inode ilock.
That resulted in xfs_fsr deadlocking itself on platforms, which
don't handle double unlock of rw_semaphore nicely. It caused the
count go negative, which represents the write holder, without
really having one. ia64 is one of the platforms where deadlock
was easily reproduced and the fix was tested.

A quirk that we've always supported is having an sg entry that's
bigger than a page, or more generally an sg entry that crosses
page boundaries.  Even though it would be better to explicitly have
to sg entries for this, we need to support it for the existing users,
in particular, IPsec.

The new ahash sg walking code did try to handle this, but there was
a bug where we didn't increment the page so kept on walking on the
first page over an dover again.

This patch fixes it.
