Michael J. Ruhl 34ab4de77f IB/hif1: Remove static tracing from SDMA hot path
The hfi1_cdbg() macro can be instantiated in the hot path even when it
is not in use.  This shows up on perf profiles.

Rework the macros (for SDMA and MMU), to use the trace interface directly
to eliminate this performance hit.

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.
