Restore function signatures from bool to int so that we can report
memory allocation failures or similar using -ENOMEM rather than
always having to pass -EINVAL back.
This semantic patch may not be too precise (checking for functions
that use xt_mtchk_param rather than functions referenced by
xt_match.checkentry), but reviewed, it produced the intended result.

The order of the IPv6 raw table is currently reversed, that makes impossible
to use the NOTRACK target in IPv6: for example if someone enters
ip6tables -t raw -A PREROUTING -p tcp --dport 80 -j NOTRACK
and if we receive fragmented packets then the first fragment will be
untracked and thus skip nf_ct_frag6_gather (and conntrack), while all
subsequent fragments enter nf_ct_frag6_gather and reassembly will never
successfully be finished.

In the extended CSD register the CARD_TYPE is an 8-bit value of which the
upper 6 bits were reserved in JEDEC specifications prior to version 4.4.
In version 4.4 two of the reserved bits were designated for identifying
support for the newly added High-Speed Dual Data Rate. Unfortunately the
mmc_read_ext_csd() function required that the reserved bits be zero
instead of ignoring them as it should.
This patch makes mmc_read_ext_csd() ignore the CARD_TYPE bits that are
reserved or not yet supported. It also stops the function jumping to the
end as though an error occurred, when it is only warns that the CARD_TYPE
bits (that it does interpret) are invalid.

Commit 57fe60df ("reiserfs: add atomic addition of selinux attributes
during inode creation") contains a bug that will cause it to oops when
mounting a file system that didn't previously contain extended attributes
on a system using security.* xattrs.
The issue is that while creating the privroot during mount
reiserfs_security_init calls reiserfs_xattr_jcreate_nblocks which
dereferences the xattr root. The xattr root doesn't exist, so we get an
oops.

Add support for basic configuration of a connection quality monitoring to the
nl80211 interface, and basic support for notifying about triggered monitoring
events.
Via this interface a user-space connection manager may configure and receive
pre-warning events of deteriorating WLAN connection quality, and start
preparing for roaming in advance, before the connection is already lost.
An example usage of such a trigger is starting scanning for nearby AP's in
an attempt to find one with better connection quality, and associate to it
before the connection characteristics of the existing connection become too bad
or the association is even lost, leading in a prolonged delay in connectivity.
The interface currently supports only RSSI, but it could be later extended
to include other parameters, such as signal-to-noise ratio, if need for that
arises.

The dma map fields in the skb_shared_info structure no longer has any users
and can be dropped since it is making the skb_shared_info unecessarily larger.
Running slabtop show that we were using 4K slabs for the skb->head on x86_64 w/
an allocation size of 1522. It turns out that the dma_head and dma_maps array
made skb_shared large enough that we had crossed over the 2k boundary with
standard frames and as such we were using 4k blocks of memory for all skbs.

This macro worked only when applied to variables named 'kobj'.
While this could have been fixed by simply renaming the macro argument,
a more type-safe replacement by an inline function would be preferred.
However, nobody uses this macro, so it's simpler to just remove it.

Create a common platform data header file for the
shdma dmaengine driver. This is done by moving
common structures from sh asm/dmaengine.h to
linux/sh_dma.h. DMA registers are also copied from
sh asm/dma-register.h to make the code architecture
independent.
The sh header file asm/dmaengine.h is still kept
with the slave id enum. This allows us to keep the
old processor specific code as is and slowly move
over to slave id enums in per-processor headers.

This patch replaces the sh_dmae_slave_chan_id enum
with an unsigned int. The purpose of this chainge is
to make it possible to separate the slave id enums
from the dmaengine header.
The slave id enums varies with processor model, so in
the future it makes sense to put these in the processor
specific headers together with the pinmux enums.

Its currently hard to diagnose when ACK frames are dropped because an
application set TCP_DEFER_ACCEPT on its listening socket.
See http://bugzilla.kernel.org/show_bug.cgi?id=15507
This patch adds a SNMP value, named TCPDeferAcceptDrop
netstat -s | grep TCPDeferAcceptDrop
TCPDeferAcceptDrop: 0
This counter is incremented every time we drop a pure ACK frame received
by a socket in SYN_RECV state because its SYNACK retrans count is lower
than defer_accept value.

USB 3 and Wireless USB specify a logarithmic encoding of the endpoint
interval that matches the USB 2 specification. usb_fill_int_urb() didn't
know that and was filling in the interval as if it was USB 1.1. Fix
usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case
alone, because David Vrabel wants to keep the old encoding.
Update the struct urb kernel doc to note that SuperSpeed URBs must have
urb->interval specified in microframes.
Add a missing break statement in the usb_submit_urb() interrupt URB
checking, since wireless USB and SuperSpeed USB encode urb->interval
differently. This allows xHCI roothubs to actually register with khubd.

Commit e1108a63e10d344284011cccc06328b2cd3e5da3 ("usb_serial: Use the
shutdown() operation") breaks the ability to use a usb console
starting in 2.6.33. This was observed when using
console=ttyUSB0,115200 as a boot argument with an FTDI device. The
error is:
ftdi_sio ttyUSB0: ftdi_submit_read_urb - failed submitting read urb, error -22
The handling of the ASYNCB_INITIALIZED changed in 2.6.32 such that in
tty_port_shutdown() it always clears the flag if it is set. The fix
is to add a variable to the tty_port struct to indicate when the tty
port is a console.

The TTY layer takes some care to ensure that only sub-page allocations
are made with interrupts disabled. It does this by setting a goal of
"TTY_BUFFER_PAGE" to allocate. Unfortunately, while TTY_BUFFER_PAGE takes the
size of tty_buffer into account, it fails to account that tty_buffer_find()
rounds the buffer size out to the next 256 byte boundary before adding on
the size of the tty_buffer.
This patch adjusts the TTY_BUFFER_PAGE calculation to take into account the
size of the tty_buffer and the padding. Once applied, tty_buffer_alloc()
should not require high-order allocations.

a VT_RELDISP ioctl call"
This reverts commit eec9fe7d1ab4a0dfac4cb43047a7657fffd0002f.
Ari writes as the reason this should be reverted:
The problems with this patch include:
1. There's at least one subtlety I overlooked - switching
between X servers (i.e. from one X VT to another) still requires
the cooperation of both X servers. I was assuming that KMS
eliminated this.
2. It hasn't been tested at all (no X server patch exists which
uses the new mode).
As he was the original author of the patch, I'll revert it.
