While operating from sysFS the TMC-ETR driver needs to make sure it has
memory to work with but doesn't allocate memory uselessly either.  Since
the main memory handle for this driver is drvdata::vaddr, use it throughout
function tmc_enable_etr_sink_sysfs() so that things are consistent.

With VMBus protocol 5.0, we're able to better support new features, e.g.
running two or more VMBus drivers simultaneously in a single VM -- note:
we can't simply load the current VMBus driver twice, instead, a secondary
VMBus driver must be implemented.

This patch adds the support for the new VMBus protocol, which is available
on new Windows hosts, by:

1) We still use SINT2 for compatibility;
2) We must use Connection ID 4 for the Initiate Contact Message, and for
subsequent messages, we must use the Message Connection ID field in
the host-returned VersionResponse Message.

Notes for developers of the secondary VMBus driver:
1) Must use VMBus protocol 5.0 as well;
2) Must use a different SINT number that is not in use.
3) Must use Connection ID 4 for the Initiate Contact Message, and for
subsequent messages, must use the Message Connection ID field in
the host-returned VersionResponse Message.
4) It's possible that the primary VMBus driver using protocol version 4.0
can work with a secondary VMBus driver using protocol version 5.0, but it's
recommended that both should use 5.0 for new Hyper-V features in the future.

binder_update_page_range needs down_write of mmap_sem because
vm_insert_page need to change vma->vm_flags to VM_MIXEDMAP unless
it is set. However, when I profile binder working, it seems
every binder buffers should be mapped in advance by binder_mmap.
It means we could set VM_MIXEDMAP in binder_mmap time which is
already hold a mmap_sem as down_write so binder_update_page_range
doesn't need to hold a mmap_sem as down_write.
Please use proper API down_read. It would help mmap_sem contention

New devices launching with Android P need to use the 64-bit
binder interface, even on 32-bit SoCs [0].

This change removes the Kconfig option to select the 32-bit
binder interface. We don't think this will affect existing
userspace for the following reasons:
1) The latest Android common tree is 4.14, so we don't
   believe any Android devices are on kernels >4.14.
2) Android devices launch on an LTS release and stick with
   it, so we wouldn't expect devices running on <= 4.14 now
   to upgrade to 4.17 or later. But even if they did, they'd
   rebuild the world (kernel + userspace) anyway.
3) Other userspaces like 'anbox' are already using the
   64-bit interface.

Note that this change doesn't remove the 32-bit UAPI
itself; the reason for that is that Android userspace
always uses the latest UAPI headers from upstream, and
userspace retains 32-bit support for devices that are
upgrading. This will be removed as well in 2-3 years,
at which point we can remove the code from the UAPI
as well.

Finally, this change introduces build errors on archs where
64-bit get_user/put_user is not supported, so make binder
unavailable on m68k (which wouldn't want it anyway).

 "Another set of x86 related updates:

   - Fix the long broken x32 version of the IPC user space headers which
     was noticed by Arnd Bergman in course of his ongoing y2038 work.
     GLIBC seems to have non broken private copies of these headers so
     this went unnoticed.

   - Two microcode fixlets which address some more fallout from the
     recent modifications in that area:

      - Unconditionally save the microcode patch, which was only saved
        when CPU_HOTPLUG was enabled causing failures in the late
        loading mechanism

      - Make the later loader synchronization finally work under all
        circumstances. It was exiting early and causing timeout failures
        due to a missing synchronization point.

   - Do not use mwait_play_dead() on AMD systems to prevent excessive
     power consumption as the CPU cannot go into deep power states from
     there.

   - Address an annoying sparse warning due to lost type qualifiers of
     the vmemmap and vmalloc base address constants.

   - Prevent reserving crash kernel region on Xen PV as this leads to
     the wrong perception that crash kernels actually work there which
     is not the case. Xen PV has its own crash mechanism handled by the
     hypervisor.

   - Add missing TLB cpuid values to the table to make the printout on
     certain machines correct.

   - Enumerate the new CLDEMOTE instruction

The comment claims that this helper will try not to loose bits, but for
64bit long it looses the high bits before hashing 64bit long into 32bit
int.  Use the helper hash_long() to do the right thing for 64bit long.
For 32bit long, there is no change.

All the callers of end_name_hash() either assign the result to
qstr->hash, which is u32 or return the result as an int value (e.g.
full_name_hash()).  Change the helper return type to int to conform to
its users.

[ It took me a while to apply this, because my initial reaction to it
  was - incorrectly - that it could make for slower code.

  After having looked more at it, I take back all my complaints about
  the patch, Amir was right and I was mis-reading things or just being
  stupid.

  I also don't worry too much about the possible performance impact of
  this on 64-bit, since most architectures that actually care about
  performance end up not using this very much (the dcache code is the
  most performance-critical, but the word-at-a-time case uses its own
  hashing anyway).

  So this ends up being mostly used for filesystems that do their own
  degraded hashing (usually because they want a case-insensitive
  comparison function).

  A _tiny_ worry remains, in that not everybody uses DCACHE_WORD_ACCESS,
  and then this potentially makes things more expensive on 64-bit
  architectures with slow or lacking multipliers even for the normal
  case.

  That said, realistically the only such architecture I can think of is
  PA-RISC. Nobody really cares about performance on that, it's more of a
  "look ma, I've got warts^W an odd machine" platform.

  So the patch is fine, and all my initial worries were just misplaced
  from not looking at this properly.   - Linus ]
