It is for most of it, but I needed to know what bit represents a BAKR
call vs. a PC. This is all I could find:

---
Bytes 288-295 contain the entry
descriptor. EXTRACT STACKED STATE sets the
condition code to indicate whether the entry-type
code in the entry descriptor specifies a branch state
entry or a program-call state entry.
---

I can't very well issue ESTA looking at a dump. For BAKR and non-
fastpath PC calls that create the linkage stack, the registers are
stored in the USTA which also I can't find documented anywhere other
than the aforementioned Share presentation.
