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.

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

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.
