Huang Xiaojia 684fbd42d3 arm64: Constify struct kobj_type
'struct kobj_type' is not modified. It is only used in kobject_init()
which takes a 'const struct kobj_type *ktype' parameter.

Constifying this structure moves some data to a read-only section,
so increase over all security.

On a x86_64, compiled with arm defconfig:
Before:
======
   text	   data	    bss	    dec	    hex	filename
   5602	    548	    352	   6502	   1966	arch/arm64/kernel/cpuinfo.o

After:
======
   text    data     bss     dec     hex filename
   5650     500     352    6502    1966 arch/arm64/kernel/cpuinfo.o

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
