HashKey computation only needs to happen once per scatter/gather operation, save it between calls in gcm_context struct instead of on the stack. Since the asm no longer stores anything on the stack, we can use %rsp directly, and clean up the frame save/restore macros a bit. Hashkeys actually only need to be calculated once per key and could be moved to when set_key is called, however, the current glue code falls back to generic aes code if fpu is disabled.

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.
