Xi Wang 98ffd22bd1 RDMA/hns: Fixs hw access invalid dma memory error 
[ Upstream commit ec5bc2cc69 ]

When smmu is enable, if execute the perftest command and then use 'kill
-9' to exit, follow this operation repeatedly, the kernel will have a high
probability to print the following smmu event:

  arm-smmu-v3 arm-smmu-v3.1.auto: event 0x10 received:
  arm-smmu-v3 arm-smmu-v3.1.auto:  0x00007d0000000010
  arm-smmu-v3 arm-smmu-v3.1.auto:  0x0000020900000080
  arm-smmu-v3 arm-smmu-v3.1.auto:  0x00000000f47cf000
  arm-smmu-v3 arm-smmu-v3.1.auto:  0x00000000f47cf000

This is because the hw will periodically refresh the qpc cache until the
next reset.

This patch fixed it by removing the action that release qpc memory in the
'hns_roce_qp_free' function.

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.
