The crashed member of struct iss_device is documented to be a bitmask,
but a bool doesn't hold that many (usable) bits. Lines 589 and 659 of
iss.c strongly suggest that "unsigned int" was meant (the same type as
struct iss_pipeline::entities). Currently, any crashed entity will be
blamed on index 0, which is unlikely to be what was intended.

Patch originally written by Konrad. Rebased on current linux media tree.
Under Xen, vmalloc_32() isn't guaranteed to return pages which are really
under 4G in machine physical addresses (only in virtual pseudo-physical
addresses). To work around this, implement a vmalloc variant which
allocates each page with dma_alloc_coherent() to guarantee that each
page is suitable for the device in question.

Some fe drivers will have to do additional initialization
in their fe ops.init interfaces when called during resume.
Without the additional initialization, fe and tuner driver
resume fails. A new fe exit flag value DVB_FE_DEVICE_RESUME
is necessary to detect resume case. This patch adds a new
define and changes dvb_frontend_resume() to set it prior to
calling fe init and tuner init calls and resets it back to
DVB_FE_NO_EXIT once fe and tuner init is done.

Some fe drivers attempt to access the device for power control from
their release routines. When release routines are called after device
is disconnected, the attempts fail. fe drivers should avoid accessing
the device, from their release interfaces when called from disconnect
path. dvb-frontend maintains exit flag to keep track when fe device is
disconnected in its private data structures. Export the flag in fe to
enable drivers to check the device status from their release interfaces.

This tries to make them more like other remotes, and/or
the button labels.
Notably, the (>>) button is made KEY_FASTFORWARD, which is the
correct opposite of (<<)'s KEY_REVERSE. (It was KEY_FORWARD,
something else entirely.)
Likewise, KEY_STOP is the Sun keyboard "interrupt program" key;
the media key is KEY_STOPCD.
A restriction is that I try to avoid keycodes above 255, as the X11
client/server protocol is limited to 8-bit key codes. If not for
this, I would have used the KEY_NUMERIC_x codes for the numbers.

An input report is 4 bytes long, but there are only 12 bits
of actual payload. The 4 bytes are:
data[0] = 0x14
data[1] = data[2] + data[3] + 0xd5 (a checksum byte)
data[2] = the raw scancode (plus toggle bit in msbit)
data[3] = channel << 4 (the low 4 bits must be zero)

The hole point of IR_dprintk() is that, once a level is
given at debug parameter, all enabled IR parsers will show their
debug messages.
While converting it to dynamic_printk might be a good idea,
right now it just makes very hard to debug the drivers, as
one needs to both pass debug=1 or debug=2 to rc-core and
to use the dynamic printk to enable all the desired lines.
That doesn't make sense!
So, revert to the old way, as a single line is changed,
and the debug parameter will now work as expected.
