The old drivers/char/rtc.c driver was originally the implementation
for x86 PCs but got subsequently replaced by the rtc class driver
on all architectures except alpha.

Move alpha over to the portable driver and remove the old one
for good.

The CONFIG_JS_RTC option was only ever used on SPARC32 but
has not been available for many years, this was used to build
the same rtc driver with a different module name.

When I first wrote binderfs the new mount api had not yet landed. Now
that it has been around for a little while and a bunch of filesystems
have already been ported we should do so too. When Al sent his
mount-api-conversion pr he requested that binderfs (and a few others) be
ported separately. It's time we port binderfs. We can make use of the
new option parser, get nicer infrastructure and it will be easier if we
ever add any new mount options.

This survives testing with the binderfs selftests:

for i in `seq 1 1000`; do ./binderfs_test; done

including the new stress tests I sent out for review today:

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

 "We've been accruing these for a couple of weeks, so the batch is a bit
  bigger than usual.

  Largest delta is due to a led-bl driver that is added -- there was a
  miscommunication before the merge window and the driver didn't make it
  in. Due to this, the platforms needing it regressed. At this point, it
  seemed easier to add the new driver than unwind the changes.

  Besides that, there are a handful of various fixes:

   - AMD tee memory leak fix

   - A handful of fixlets for i.MX SCU communication

Pull rdma fixes from Jason Gunthorpe:
 "Nothing particularly exciting, some small ODP regressions from the mmu
  notifier rework, another bunch of syzkaller fixes, and a bug fix for a
  botched syzkaller fix in the first rc pull request.

   - Fix busted syzkaller fix in 'get_new_pps' - this turned out to
     crash on certain HW configurations

   - Bug fixes for various missed things in error unwinds

   - Add a missing rcu_read_lock annotation in hfi/qib

   - Fix two ODP related regressions from the recent mmu notifier
     changes

   - Several more syzkaller bugs in siw, RDMA netlink, verbs and iwcm

   - Revert an old patch in CMA as it is now shown to not be allocating
     port numbers properly"
