It seems that MCOUNT_INSN_OFFSET was calculating the distance between

The prototypes in syscalls.h all make sense for
microblaze, but for some of them, the actual implementation
in sys_microblaze.c needs to be adapted.

When legacy signal handling is disabled, the
arch/microblaze/kernel/signal.c implementation can
be much simpler, as most of it is handled generically
from kernel/signal.c.
This is also a prerequisite for using the generic
asm/unistd.h, which does not provide __NR_sigreturn,
because this macro is referenced by the current signal.c
implementation.

The call resource_size(res) returns res->end - res->start + 1 and thus the
second change is semantics-preserving. res_size is then used as the second
argument of a call to request_mem_region, and the memory allocated by this
call appears to be the same as what is released in the two calls to
release_mem_region. So the size argument for those calls should be
resource_size(size) as well. Alternatively, in the second call to
release_mem_region, the second argument could be res_size, as that variable
has already been initialized at the point of this call.
The problem was found using the following semantic patch:

It is currently possible for an asynchronous device unregister
to cause the same tun device to be unregistered twice. This
is because the unregister in tun_chr_close only checks whether
__tun_get(tfile) != NULL. This however has nothing to do with
whether the device has already been unregistered. All it tells
you is whether __tun_detach has been called.
This patch fixes this by using the most obvious thing to test
whether the device has been unregistered.
It also moves __tun_detach outside of rtnl_unlock since nothing
that it does requires that lock.

Fix the code so that the zl10353 version of the Terratec Cinergy T XS USB

GPIO definition for the digital side of the board, and setting of the
disable_i2c_gate_ctrl property for the zl10353 config, so that the i2c bus
doesn't get wedged the first time something tries to close the gate.
Also, add a printk() making clear that the mt352 version still isn't
supported. This issue is still being actively debugged, but in the meantime
at least the dmesg output will show a very clear error...

The original driver for Silvercrest cameras were using some values that

Instead of working with a table of precalculated values, fill them with
the proper values. Also, adds format functions that allow changing the
resolution, by cropping the image to the center of the sensor.
While here, move the sensor version check to the probe routine, to
indicate to the caller if the sensor is not supported by this driver.
Also, fixes a stupid bug where we're using &buffer[] instead of
buffer[].

Add DVB-T support for Yuan MPC-718 cards with an MT352 or ZL10353 demodulator.
There are apparently some units with a DiBcom demodulator which could be
supported by one of the dib7000 modules - but this is not implemented in the
cx18 driver (yet).
Due to lack of porgramming details for the MT352 and the mt352 module requiring
a "demod_init" function, a "firmware" must be obtained and loaded to get
DVB-T working for Yuan MPC-718 cards with an MT352.
