  1. qpnp-fg-gen3: Fix fg_sram_write() call in clear_cycle_counter() 

    This not only passes the incorrect size to fg_sram_write(), but also
uses incorrect syntax to pass the pointer of the payload to be written.
`chip->cyc_ctr.count` is defined as an array so there shouldn't be an
ampersand in front of it to get its address. We can also get its size
with just a plain sizeof().

  2. fs: aio: Optimization for SSD-only machines 

    If the system is running on NAND-based storage, without
mechanical drives, we don't need to manage the plug/unplug
of the actual block because we don't have to count the
time for the head to reach that disk physical location.
Solid state storage have no head to move and no location
to "physically reach", as the block is being retrieved
in the exact moment we request it.

The do_io_submit function expects the storage device to
be ready to deliver the block (aka - next block of the
queue to process), therefore it's safe to remove useless
waits on systems using only that type of storage.

This patch adds a configuration option to enable the
SSD-only optimization for the Linux Asynchronous IO
framework.
Enabling it on systems with rotational storage (or mixed)
WILL hit storage performance A LOT.

  3. FROMLIST: HID: nintendo: add nintendo switch controller driver 

    The hid-nintendo driver supports the Nintendo Switch Pro Controllers and
the Joy-Cons. The Pro Controllers can be used over USB or Bluetooth.

The Joy-Cons each create their own, independent input devices, so it is
up to userspace to combine them if desired.

  5. arm64: support __int128 on gcc 5+ 

    Versions of gcc prior to gcc 5 emitted a __multi3 function call when
dealing with TI types, resulting in failures when trying to link to
libgcc, and more generally, bad performance. However, since gcc 5,
the compiler supports actually emitting fast instructions, which means
we can at long last enable this option and receive the speedups.

The gcc commit that added proper Aarch64 support is:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=d1ae7bb994f49316f6f63e6173f2931e837a351d
This commit appears to be part of the gcc 5 release.

There are still a few instructions, __ashlti3 and __ashrti3, which
require libgcc, which is fine. Rather than linking to libgcc, we
simply provide them ourselves, since they're not that complicated.

  6. arm64: support __int128 with clang 

    Commit fb87227 ("arm64: support __int128 on gcc 5+") added support
for arm64 __int128 with gcc with a version-conditional, but neglected to
enable this for clang, which in fact appears to support aarch64 __int128.
This commit therefore enables it if the compiler is clang, using the
same type of makefile conditional used elsewhere in the tree.
