grp->slot_shift is between 22 and 41, so using 32bit wide variables is
probably a typo.

It was found (by Sasha) that if you use a futex located in the gate
area we get stuck in an uninterruptible infinite loop, much like the
ZERO_PAGE issue.
While looking at this problem, PeterZ realized you'll get into similar
trouble when hitting any install_special_pages() mapping. And are there
still drivers setting up their own special mmaps without page->mapping,
and without special VM or pte flags to make get_user_pages fail?
In most cases, if page->mapping is NULL, we do not need to retry at all:
Linus points out that even /proc/sys/vm/drop_caches poses no problem,
because it ends up using remove_mapping(), which takes care not to
interfere when the page reference count is raised.
But there is still one case which does need a retry: if memory pressure
called shmem_writepage in between get_user_pages_fast dropping page
table lock and our acquiring page lock, then the page gets switched from
filecache to swapcache (and ->mapping set to NULL) whatever the refcount.
Fault it back in to get the page->mapping needed for key->shared.inode.

The sanity check (timeout < 0) never works; the dividend is unsigned
and so is the division, which should have been a signed division.
long timeout = (ct->timeout.expires - jiffies) / HZ;
if (timeout < 0)
timeout = 0;
This patch converts the time values to signed for the division.

Just like set_frontend, use the dvb cache properties for get_frontend.
This is more consistent, as both functions are now symetric. Also,
at the places get_frontend is called, it makes sense to update the
cache.
Most of this patch were generated by this small perl script:
while (<>) { $file .= $_; }
if ($file =~ m/\.get_frontend\s*=\s*([\d\w_]+)/) {
my $get = $1;
$file =~ s/($get)(\s*\([^\,\)]+)\,\s*struct\s+dtv_frontend_properties\s*\*\s*([_\d\w]+)\)\s*\{/\1\2)\n{\n\tstruct dtv_frontend_properties *\3 = &fe->dtv_property_cache;/g;
}
print $file;
Of course, the changes at dvb_frontend.[ch] were made by hand,
as well as the changes on a few other places, where get_frontend()
is called internally inside the driver.
On some places, get_frontend() were just a void function. Those
occurrences were removed, as the DVB core handles such cases.

Now that all frontends are implementing DVBv5, don't export the
DVBv3 specific stuff to the drivers. Only the core should be
aware of that, as it will keep providing DVBv3 backward compatibility.

The cx23885-dvb driver has a dirty hack:
1) it hooks the DVBv3 legacy call to FE_SET_FRONTEND;
2) it uses internally the DVBv3 struct to decide some
configs.
Replace it by a change during the gate control. This will
likely work, but requires testing. Anyway, the current way
will break, as soon as we stop copying data for DVBv3 for
pure DVBv5 calls.
Compile-tested only.

Just like the other DVB algorithms, drivers should use the DVBv5
way to retrieve parameters: via the cache struct.
Actually, several drivers were partially using the DVBv3 struct
and partially using the DVBv5 way, with is confusing and may
lead into troubles.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
As all parameters are passed via DVBv5 to the frontends, there's
no need to pass them again via fops. Also, most drivers weren't using
it anyway. So, instead, just pass a parameter to indicate if the
hardware algorithm wants the driver to re-tune or not.

In the past, dvb_frontent_parameters were passed inside the
struct where get_tuner_settings should store their result.
This is not needed anymore, as all parameters needed are stored
already at the fe property cache. So, use it, where needed.
