Mike Rapoport 94393c7896 mm/mprotect.c: fix compilation warning because of unused 'mm' variable 
Since 0cbe3e26ab ("mm: update ptep_modify_prot_start/commit to take
vm_area_struct as arg") the only place that uses the local 'mm' variable
in change_pte_range() is the call to set_pte_at().

Many architectures define set_pte_at() as macro that does not use the 'mm'
parameter, which generates the following compilation warning:

 CC      mm/mprotect.o
mm/mprotect.c: In function 'change_pte_range':
mm/mprotect.c:42:20: warning: unused variable 'mm' [-Wunused-variable]
  struct mm_struct *mm = vma->vm_mm;
                    ^~

Fix it by passing vma->mm to set_pte_at() and dropping the local 'mm'
variable in change_pte_range().

README 

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 Restructured Text 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.
