9f2394c9be Revert "ext4: allow readdir()'s of large empty directories to be interrupted"
This reverts commit 1028b55bafb7611dda1d8fed2aeca16a436b7dff.

It's broken: it makes ext4 return an error at an invalid point, causing
the readdir wrappers to write the the position of the last successful
directory entry into the position field, which means that the next
readdir will now return that last successful entry _again_.

You can only return fatal errors (that terminate the readdir directory
walk) from within the filesystem readdir functions, the "normal" errors
(that happen when the readdir buffer fills up, for example) happen in
the iterorator where we know the position of the actual failing entry.

I do have a very different patch that does the "signal_pending()"
handling inside the iterator function where it is allowable, but while
that one passes all the sanity checks, I screwed up something like four
times while emailing it out, so I'm not going to commit it today.

So my track record is not good enough, and the stars will have to align
better before that one gets committed.  And it would be good to get some
review too, of course, since celestial alignments are always an iffy
debugging model.

IOW, let's just revert the commit that caused the problem for now.

Pull parisc fixes from Helge Deller:
 "Since commit 0de798584bde ("parisc: Use generic extable search and
  sort routines") module loading is boken on parisc, because the parisc
  module loader wasn't prepared for the new R_PARISC_PCREL32 relocations.

  In addition, due to that breakage, Mikulas Patocka noticed that
  handling exceptions from modules probably never worked on parisc.  It
  was just masked by the fact that exceptions from modules don't happen
  during normal use.

  This patch series fixes those issues and survives the tests of the
  lib/test_user_copy kernel module test.  Some patches are tagged for
  stable"

289b7bfd48 GPIO fixes for the V4.6 series:
Core fixes:
 - Defer GPIO device setup until after gpiolib is initialized.
   It turns out that a few very tightly integrated GPIO platform
   drivers initialize so early (befor core_initcall()) so that
   the gpiolib isn't even initialized itself. That limits what
   the library can do, and we cannot reference uninitialized
   fields until later. Defer some of the initialization until
   right after the gpiolib is initialized in these (rare) cases.
 - As a consequence: do not use devm_* resources when allocating
   the states in the initial set-up of the gpiochip.
 
 Driver fixes:
 - In ACPI retrieveal: ignore GpioInt when looking for output
   GPIOs.
 - Fix legacy builds on the PXA without a backing pin controller.
 - Use correct datatype on pca953x register writes.
