Commitf15f05b0a5("crypto: ccm - switch to separate cbcmac driver") refactored the CCM driver to allow separate implementations of the underlying MAC to be provided by a platform. However, in doing so, it moved some data from the linear region to the stack, which violates the SG constraints when the stack is virtually mapped. So move idata/odata back to the request ctx struct, of which we can reasonably expect that it has been allocated using kmalloc() et al.

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.
