Dean Luick dffa4afa98 IB/hfi1: Fix expected receive setup error exit issues 
[ Upstream commit e0c4a422f5 ]

Fix three error exit issues in expected receive setup.
Re-arrange error exits to increase readability.

Issues and fixes:
1. Possible missed page unpin if tidlist copyout fails and
   not all pinned pages where made part of a TID.
   Fix: Unpin the unused pages.

2. Return success with unset return values tidcnt and length
   when no pages were pinned.
   Fix: Return -ENOSPC if no pages were pinned.

3. Return success with unset return values tidcnt and length when
   no rcvarray entries available.
   Fix: Return -ENOSPC if no rcvarray entries are available.

Fixes: 7e7a436ecb ("staging/hfi1: Add TID entry program function body")
Fixes: 97736f36db ("IB/hfi1: Validate page aligned for a given virtual addres")
Fixes: f404ca4c7e ("IB/hfi1: Refactor hfi_user_exp_rcv_setup() IOCTL")

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.

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.
