68ae6639b6 Bluetooth: Fix regression with L2CAP configuration in Basic Mode
Basic Mode is the default mode of operation of a L2CAP entity. In
this case the RFC (Retransmission and Flow Control) configuration
option should not be used at all.

Normally remote L2CAP implementation should just ignore this option,
but it can cause various side effects with other Bluetooth stacks
that are not capable of handling unknown options.

a0e55a32af Bluetooth: Select Basic Mode as default for SOCK_SEQPACKET
The default mode for SOCK_SEQPACKET is Basic Mode. So when no

This is important for current application to keep working as

93f19c9fc8 Bluetooth: Set general bonding security for ACL by default
This patch fixes double pairing issues with Secure Simple
Paring support. It was observed that when pairing with SSP
enabled, that the confirmation will be asked twice.

http://www.spinics.net/lists/linux-bluetooth/msg02473.html

This also causes bug when initiating SSP connection from
Windows Vista.

The reason is because bluetoothd does not store link keys
since HCIGETAUTHINFO returns 0. Setting default to general
bonding fixes these issues.

8812304cf1 r8169: Fix receive buffer length when MTU is between 1515 and 1536
In r8169 driver MTU is used to calculate receive buffer size.
Receive buffer size is used to configure hardware incoming packet filter.

For jumbo frames:
Receive buffer size = Max frame size = MTU + 14 (ethernet header) + 4
(vlan header) + 4 (ethernet checksum) = MTU + 22

Bug:
driver for all MTU up to 1536 use receive buffer size 1536

As you can see from formula, this mean all IP packets > 1536 - 22
(for vlan tagged, 1536 - 18 for not tagged) are dropped by hardware
filter.

Example:

host_good>  ifconfig eth0 mtu 1536
host_r8169> ifconfig eth0 mtu 1536
host_good>  ping host_r8169
Ok
host_good>  ping -s 1500 host_r8169
Fail
host_good>  ifconfig eth0 mtu 7000
host_r8169> ifconfig eth0 mtu 7000
host_good>  ping -s 1500 host_r8169
Ok

Bonus: got rid of magic number 8

b93cf3f0bb can: Fix driver Kconfig structure
In 2.6.32-rc the new EMS USB CAN driver was contributed and added the Kconfig
entry right behind an entry of the same *vendor*. This teared the SJA1000
based driver selection into pieces.

This fix cleans up the 2.6.32-rc Kconfig files for the CAN drivers and moves
the SJA1000 and USB Kconfig portions into the belonging directories.

As there are many new CAN drivers in the queue getting this cleanup into
2.6.32-rc would massively reduce the problems for the upcoming drivers.

Thanks,

Due commit 4b77b0a2ba, it is not more
possible to pci_restore_state() more than once without calling
pci_save_state() in the middle.

Actually running a ethtool test on s2io makes the card inactive,

keep the old behaviour

a78102e74e sctp: Set socket source address when additing first transport
Recent commits
	sctp: Get rid of an extra routing lookup when adding a transport
and
	sctp: Set source addresses on the association before adding transports

changed when routes are added to the sctp transports.  As such,
we didn't set the socket source address correctly when adding the first
transport.  The first transport is always the primary/active one, so
when adding it, set the socket source address.  This was causing
regression failures in SCTP tests.

introduced a regression cought by the user regression test
suite.  In particular, the API requires the user library to

This change corrects that regression by passing the original
address buffer to the kernel unmodified, but still allows for
a returned association id.

409b95aff3 sctp: Set source addresses on the association before adding transports
Recent commit 8da645e101
	sctp: Get rid of an extra routing lookup when adding a transport
introduced a regression in the connection setup.  The behavior was

different between IPv4 and IPv6.  IPv4 case ended up working because the
route lookup routing returned a NULL route, which triggered another
route lookup later in the output patch that succeeded.  In the IPv6 case,
a valid route was returned for first call, but we could not find a valid
source address at the time since the source addresses were not set on the
association yet.  Thus resulted in a hung connection.

The solution is to set the source addresses on the association prior to
adding peers.

c430452954 MIPS: Make local arrays with CL_SIZE static __initdata
Since commit 22242681cf ("MIPS: Extend
COMMAND_LINE_SIZE"), CL_SIZE is 4096 and local array variables with this
size will cause an build failure with default CONFIG_FRAME_WARN settings.

Although current users of such array variables are all early bootstrap
code and not likely to cause real stack overflow (thread_info corruption),
it is preferable to  to declare these arrays static with __initdata.

f8ac04255d MIPS: Add DMA declare coherent memory support
The ohci-sm501 driver requires dma_declare_coherent_memory().  It is used
by the driver's local memory allocation with dma_alloc_coherent().

Tested on TANBAC TB0287(VR4131 + SM501).

[Ralf: Fixed reject in dma-default.c and removed the entire #if 0'ed block
 in dma-mapping.h instead of just the #if 0.]

da0bac3341 MIPS: Fix emulation of 64-bit FPU on FPU-less 64-bit CPUs.
Running a 64-bit kernel on a 64-bit CPU without an FPU would cause the
emulator to run in 32-bit mode.  The c0_Status.FR bit is wired to zero
on systems without an FPU, so using that bit to decide how the emulator
behaves doesn't allow for proper emulation on 64-bit FPU-less
processors.

Instead, we need to select the emulator mode based on the user-space
ABI.  Since the thread flag TIF_32BIT_REGS is used to set c0_Status.FR,
we can just use it to decide if the emulator should be in 32-bit or
64-bit mode.
