Throughout the OpenRISC kernel port VMA is passed as NULL when flushing kernel tlb entries. Somehow this was missed when I was testingc28b27416d("openrisc: Implement proper SMP tlb flushing") and now the SMP kernel fails to completely boot. In OpenRISC VMA is used only to determine which cores need to have their TLB entries flushed. This patch updates the logic to flush tlbs on all cores when the VMA is passed as NULL. Also, we update places VMA is passed as NULL to use flush_tlb_kernel_range instead. Now, the only place VMA is passed as NULL is in the implementation of flush_tlb_kernel_range.

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.
