nx_build_sg_list - build an NX scatter list describing a single buffer
: pointer to the first scatter list element to build : pointer to the linear buffer : length of the data at : the largest number of scatter list elements we're allowed to create
This function will start writing nx_sg elements at and keep writing them until all of the data from is described or until sgmax elements have been written. Scatter list elements will be created such that none of the elements describes a buffer that crosses a 4K boundary.

nx_build_sg_lists - walk the input scatterlists and build arrays of NX scatterlists based on them.
: NX crypto context for the lists we're building : the block cipher descriptor for the operation : destination scatterlist : source scatterlist : length of data described in the scatterlists : destination for the iv data, if the algorithm requires it
This is common code shared by all the AES algorithms. It uses the block cipher walk routines to traverse input and output scatterlists, building corresponding NX scatterlists

Author: Kent Yoder yoder1@us.ibm.com nx_hcall_sync - make an H_COP_OP hcall for the passed in op structure
: the crypto context handle : PFO operation struct to pass in : flag indicating the request can sleep
Make the hcall, retrying while the hardware is busy. If we cannot yield the thread, limit the number of retries to 10 here.

nx_walk_and_build - walk a linux scatterlist and build an nx scatterlist
: pointer to the first nx_sg element to write : max number of nx_sg entries we're allowed to write : pointer to the source linux scatterlist to walk : number of bytes to fast-forward past at the beginning of : number of bytes to walk in
