When the user enables breakpoints through dr7, he can choose
between "local" or "global" enable bits but given how linux is
implemented, both have the same effect.
That said we don't keep track how the user enabled the breakpoints
so when the user requests the dr7 value, we only translate the
"enabled" status using the global enabled bits. It means that if
the user enabled a breakpoint using the local enabled bit, reading
back dr7 will set the global bit and clear the local one.
Apps like Wine expect a full dr7 POKEUSER/PEEKUSER match for emulated
softwares that implement old reverse engineering protection schemes.
We fix that by keeping track of the whole dr7 value given by the user
in the thread structure to drop this bug. We'll think about
something more proper later.
This fixes a 2.6.32 - 2.6.33-x ptrace regression.

Before we had a generic breakpoint API, ptrace was accepting
breakpoints on NULL address in x86. The new API refuse them,
without given strong reasons. We need to follow the previous
behaviour as some userspace apps like Wine need such NULL
breakpoints to ensure old emulated software protections
are still working.
This fixes a 2.6.32 - 2.6.33-x ptrace regression.

Move I2C IR initialization from just after I2C bus setup to right
before non-I2C IR initialization. This avoids the case where an I2C IR
device is blocking audio support (at least the PV951 suffers from
this). It is also more logical to group IR support together,
regardless of the connectivity.

I'm trying to fix it on the GCC side (PR43007), but the module is
quite stupid in using ULL constants to operate on u32 values:
static int apply_frontend_param (struct dvb_frontend* fe, struct
dvb_frontend_parameters *param)
{
...
static const u32 ppm = 8000;
u32 spi_bias;
...
spi_bias *= 1000ULL;
spi_bias /= 1000ULL + ppm/1000;
which causes current GCC 4.5 to emit calls to __udivdi3 for i?86 again.

Most laptops have keys that are intended to toggle all device state, not
just wifi. These are currently generally mapped to KEY_WLAN. As a result,
rfkill will only kill or enable wifi in response to the key press. This

and wwan devices.
This patch adds a new keycode, KEY_RFKILL. It indicates that the system
should toggle the state of all rfkillable devices.

There is 3 different distinct states for an indirect buffer (IB) :
1- free with no fence
2- free with a fence
3- non free (fence doesn't matter)
Previous code mixed case 2 & 3 in a single one leading to possible
catastrophique failure. This patch rework the handling and properly
separate each case. So when you get ib we set the ib as non free and
fence status doesn't matter. Fence become active (ie has a meaning
for the ib code) once the ib is scheduled or free. This patch also
get rid of the alloc bitmap as it was overkill, we know go through
IB pool list like in a ring buffer as the oldest IB is the first
one the will be free.

Currently we're gracefully tearing down each active connection
when fcoe.ko is removed. We shouldn't allow the user to destroy
connections by removing the module. We should force the user to
destroy each connection and then the module can be removed.
This patch makes it so a refrerence count on the module is taken
each time a fcoe_interface is created. The reference count
is dropped when the fcoe_interface is destroyed. This makes it
so that module_exit() doesn't get called unless all fcoe_interfaces
have been destroyed.
This patch leaves the removal of interfaces in the module_exit
routine so that if the user does a 'rmmod -f' we'll clean everything
up before removing the module.
The module_put line was put before the out_putdev goto line because
we should only be decrementing the reference count if a
fcoe_interface is actually destroyed. If we can't find the netdev
or the fcoe_interface then it's assumed that something else has
destroyed the fcoe_interface and it would have decremented the
reference count at that time.

When controlling an industrial radio modem it can be necessary to
manipulate the handshake lines in order to control the radio modem's
transmitter, from userspace.
The transmitter should not be turned off before all characters have been
transmitted. serial8250_tx_empty() was reporting that all characters were
transmitted before they actually were.

Discovered in parallel with more testing and analysis by Kees Schoenmakers
as follows:
I ran into an NetMos 9835 serial pci board which behaves a little
different than the standard. This type of expansion board is very common.
"Standard" 8250 compatible devices clear the 'UART_LST_TEMT" bit together
with the "UART_LSR_THRE" bit when writing data to the device.
The NetMos device does it slightly different
I believe that the TEMT bit is coupled to the shift register. The problem
is that after writing data to the device and very quickly after that one
does call serial8250_tx_empty, it returns the wrong information.
My patch makes the test more robust (and solves the problem) and it does
not affect the already correct devices.
Alan:
We may yet need to quirk this but now we know which chips we have a
way to do that should we find this breaks some other 8250 clone with
dodgy THRE.
