Sebastian Ott 34196f82b1 [S390] chsc: consolidate memory allocations ... Most wrappers around the channel subsystem call have their own logic to allocate memory (with proper alignment) or use preallocated or static memory. This patch converts most users of the channel subsystem call to use the same preallocated page (proteced by a spinlock). Note: The sei_page which is used in our crw handler to call "store event information" has to coexist, since a) in crw context, while accessing the sei_page, sleeping is allowed (which will conflict with the spinlock protection of the chsc_page) b) in crw context, while accessing the sei_page, channel subsystem calls are allowed (which itself would require the page).
