Bob Pearson 65a81b61d8 RDMA/rxe: Fix memory allocation while in a spin lock 
rxe_mcast_add_grp_elem() in rxe_mcast.c calls rxe_alloc() while holding
spinlocks which in turn calls kzalloc(size, GFP_KERNEL) which is
incorrect.  This patch replaces rxe_alloc() by rxe_alloc_locked() which
uses GFP_ATOMIC.  This bug was caused by the below mentioned commit and
failing to handle the need for the atomic allocate.

Fixes: 4276fd0ddd ("RDMA/rxe: Remove RXE_POOL_ATOMIC")

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.
