Michael J. Ruhl d7d626179f IB/hfi1: Fix incorrect available receive user context count
The addition of the VNIC contexts to num_rcv_contexts changes the
meaning of the sysfs value nctxts from available user contexts, to
user contexts + reserved VNIC contexts.

User applications that use nctxts are now broken.

Update the calculation so that VNIC contexts are used only if there are
hardware contexts available, and do not silently affect nctxts.

Update code to use the calculated VNIC context number.

Update the sysfs value nctxts to be available user contexts only.

README

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

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
