Subject: [PATCH net-next 0/2] sparc64 eBPF JIT


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.

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
