Chintan Pandya 05e3ff9505 mm: vmalloc: pass proper vm_start into debugobjects
Client can call vunmap with some intermediate 'addr' which may not be
the start of the VM area.  Entire unmap code works with vm->vm_start
which is proper but debug object API is called with 'addr'.  This could
be a problem within debug objects.

Pass proper start address into debug object API.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
