powerpc: Wire up sys_bpf() syscall
This patch wires up the new syscall sys_bpf() on powerpc. Passes the tests in samples/bpf: #0 add+sub+mul OK #1 unreachable OK #2 unreachable2 OK #3 out of range jump OK #4 out of range jump2 OK #5 test1 ld_imm64 OK #6 test2 ld_imm64 OK #7 test3 ld_imm64 OK #8 test4 ld_imm64 OK #9 test5 ld_imm64 OK #10 no bpf_exit OK #11 loop (back-edge) OK #12 loop2 (back-edge) OK #13 conditional loop OK #14 read uninitialized register OK #15 read invalid register OK #16 program doesn't init R0 before exit OK #17 stack out of bounds OK #18 invalid call insn1 OK #19 invalid call insn2 OK #20 invalid function call OK #21 uninitialized stack1 OK #22 uninitialized stack2 OK #23 check valid spill/fill OK #24 check corrupted spill/fill OK #25 invalid src register in STX OK #26 invalid dst register in STX OK #27 invalid dst register in ST OK #28 invalid src register in LDX OK #29 invalid dst register in LDX OK #30 junk insn OK #31 junk insn2 OK #32 junk insn3 OK #33 junk insn4 OK #34 junk insn5 OK #35 misaligned read from stack OK #36 invalid map_fd for function call OK #37 don't check return value before access OK #38 access memory with incorrect alignment OK #39 sometimes access memory with incorrect alignment OK #40 jump test 1 OK #41 jump test 2 OK #42 jump test 3 OK #43 jump test 4 OK Signed-off-by: Pranith Kumar <bobby.prani@gmail.com> [mpe: test using samples/bpf] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
