      [media] cx88: make core less verbose · 02615ed5
      Mauro Carvalho Chehab authored 
      Along the time, several debug messages were added at cx88-cards.
While those are still useful to track some troubles with
tuners, they're too verbose:
[ 5768.281801] cx88[0]: Calling XC2028/3028 callback
[ 5768.287388] cx88[0]: Calling XC2028/3028 callback

[ 5768.306244] cx88[0]: Calling XC2028/3028 callback
...

and, most of the time, useless.

So, disable them, except if core_debug modprobe parameter
is used.

This is caused by commit c7a45e5b,
that added support for two I2C buses. A partial fix was applied
at 3de09fbb, but it doesn't cover
all cases, as the DVB core fills fe->dvb->priv with adapter->priv.

       * The EFI variable anti-bricking algorithm merged in -rc8 broke booting
   on some Apple machines because they implement EFI spec 1.10, which
   doesn't provide a QueryVariableInfo() runtime function and the logic
   used to check for the existence of that function was insufficient.
   Fix from Josh Boyer.

 * The anti-bricking algorithm also introduced a compiler warning on
   32-bit. Fix from Borislav Petkov.

      parisc: use spin_lock_irqsave/spin_unlock_irqrestore for PTE updates · bda079d3
      John David Anglin authored 
      User applications running on SMP kernels have long suffered from instability
and random segmentation faults.  This patch improves the situation although
there is more work to be done.

One of the problems is the various routines in pgtable.h that update page table
entries use different locking mechanisms, or no lock at all (set_pte_at).  This
change modifies the routines to all use the same lock pa_dbit_lock.  This lock
is used for dirty bit updates in the interruption code. The patch also purges
the TLB entries associated with the PTE to ensure that inconsistent values are
not used after the page table entry is updated.  The UP and SMP code are now
identical.

The change also includes a minor update to the purge_tlb_entries function in
cache.c to improve its efficiency.

      parisc: disable -mlong-calls compiler option for kernel modules · cf71130d
      Helge Deller authored 
      CONFIG_MLONGCALLS was introduced in commit
ec758f98 to overcome linker issues when linking
huge linux kernels, e.g. with many modules linked in.

But in the kernel module loader there is no support yet for the new relocation
types, which is why modules built with -mlong-calls can't be loaded.
Furthermore, for modules long calls are not really necessary, since we already
use stub sections which resolve long distance calls.

So, let's just disable this compiler option when compiling kernel modules.

      parisc: uaccess: fix compiler warnings caused by __put_user casting · 0f28b628
      Will Deacon authored 
      When targetting 32-bit processors, __put_user emits a pair of stw
instructions for the 8-byte case. If the type of __val is a pointer, the
marshalling code casts it to the wider integer type of u64, resulting
in the following compiler warnings:

  kernel/signal.c: In function 'copy_siginfo_to_user':
  kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
  kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
  [...]

This patch fixes the warnings by removing the marshalling code and using
the correct output modifiers in the __put_{user,kernel}_asm64 macros
so that GCC will allocate the right registers without the need to
extract the two words explicitly.

      The 'help' section of the Kconfig entry for this driver is missing
an extra alignment. That seems to violate what's stated at:
	Documentation/kbuild/kconfig-language.txt

Even if it works, the better is to add 2 extra spaces there, as
this is the common practice and helps human reading of the file.

Also, the way it is, it breaks backport trees.

      [media] cx25821-alsa: get rid of a __must_check warning · f327cabf
      Mauro Carvalho Chehab authored 
      The hole reason for __must_check is to not ignore an error.

However, a "ret" value is used at cx25821 just to avoid the
Kernel compilation to compain about it.

That, however, produces another warning (with W=1):

drivers/media/pci/cx25821/cx25821-alsa.c: In function 'cx25821_audio_fini':
drivers/media/pci/cx25821/cx25821-alsa.c:727:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable]

With the current implementation of driver_for_each_device() and
cx25821_alsa_exit_callback(), there's actually just one
very unlikely condition where it will currently produce
an error: if driver_find() returns NULL.

Ok, there's not much that can be done, as it is on a driver's
function that returns void, but it can at least print some message
if the error happens.

      [media] dib8000: Fix sub-channel range · 746f7ae0
      Mauro Carvalho Chehab authored 
      isdbt_sb_subchannel is unsigned with 8 bits. So, it will
never be -1. Instead, any value bigger than 13 is invalid.

As is, the current code generates the following warnings:

drivers/media/dvb-frontends/dib8000.c: In function 'dib8000_set_isdbt_common_channel':
drivers/media/dvb-frontends/dib8000.c:2358:3: warning: comparison is always true due to limited range of data type [-Wtype-limits]

drivers/media/dvb-frontends/dib8000.c:3160:5: warning: comparison is always false

It should also be noticed that ARIB STD-B31, item
"3.15.6.8 Number of segments" at TMCC table defines the
value 15 for unused segment, and 14 as reserved.

So, better to change the check to consider any value
bigger than 13 to mean that sub-channels should be
disabled, fixing the warning and doing the right thing
even if an invalid value is filled by userspace.
