The callee may set a field in st_other to 1 to indicate r2 should
be
treated as caller-saved. This means a trampoline must be used to
save
the current TOC before calling it and restore it afterwards, much
like
external calls.
The 'callee', what is that here in that context ?

Don't you mean the 'linker' instead ?
Should probably explain explicitly that this is the .localentry NAME, 1
directive.
