Just for my own education, can anyone explain why loading the gp is
required in the definition of copy_user.S, and strncpy_from_user.S ?
(I perfectly see why the other changes are necessary, especially in
the assembler macros to force loading the gp when a subroutine called
is made). But in copy_user.S, the comment is "# we do exceptions -- we
need the gp" , but I have not found where in the exception code the gp
register of the possibly trapping code is used.
Besides, does somebody know to whom should I submit my previous two
lines adjtimex patch, as I cannot follow axp-list neither
linux-kernel, I do not feel like sending it there.
