Replace internal sg_count() function and the convoluted logic around it with the standard sg_nents_for_len() function. src_nents, dst_nents now hold the number of SW S/G entries, instead of the HW S/G table entries. With this change, null (zero length) input data for AEAD case needs to be handled in a visible way. req->src is no longer (un)mapped, pointer address is set to 0 in SEQ IN PTR command.

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.
