  FROMGIT: binder: create node flag to request sender's security context

  Modify include/uapi/linux/android/binder.h, as commit:

  FROMGIT: binder: create node flag to request sender's security context

  introduces enums and structures, which are already defined in other
  userspace files that include the binder uapi file. Thus, the
  redeclaration of these enums and structures can lead to
  build errors. To avoid this, guard the redundant declarations
  in the uapi header with the __KERNEL__ header guard, so they
  are not exported to userspace.
