[PULL 17/27] linux-user/nios2: Properly emulate EXCP_TRAP

From: Richard Henderson The real kernel has to load the instruction and extract the imm5 field; for qemu, modify the translator to do this. The use of R_AT for this in cpu_loop was a bug. Handle the other trap numbers as per the kernel's trap_table. Reviewed-by: Alex Bennée Signed-off-by: Ric

[PULL 08/27] linux-user: Disable more prctl subcodes

From: Richard Henderson Create a list of subcodes that we want to pass on, a list of subcodes that should not be passed on because they would affect the running qemu itself, and a list that probably could be implemented but require extra work. Do not pass on unknown subcodes. Reviewed-by: Lauren
