This series adds an eBPF JIT for sparc64. Sparc32 keeps having it's cBPF JIT after these changes.
Thanks to Daniel and Alexei for their invaluable feedback and review. Signed-off-by: David S. Miller <da...@davemloft.net> --- since RFC: -- rework register allocation so that we don't have to emit move instructions to get the arguments into place for calls -- allow FP as source for 64-bit ALU move operations -- don't emit NOP instructions in prologue, instead do multiple passes so that all the branch offsets settle down -- remove unnecessary checks on imm64 loads that verifier does -- consistently use bpf2sparc[] instead of direct register references
