If bpf_jit_enable > 1, then we dump the emitted JIT compiled image after creation. Currently, only SPARC and PowerPC has similar output as in the reference implementation on x86_64. Make a small helper function in order to reduce duplicated code and make the dump output uniform across architectures x86_64, SPARC, PPC, ARM (e.g. on ARM flen, pass and proglen are currently not shown, but would be interesting to know as well), also for future BPF JIT implementations on other archs.

Fix mixed space and tabs. Put bpf_jit_load_*[] externs into bpf_jit.h "while(0)" --> "while (0)" "COND (X)" --> "COND(X)" Document branch offset calculations, and bpf_error's return sequence. Document the reason we need to emit three nops between the %y register write and the divide instruction. Remove erroneous trailing semicolons from emit_read_y() and emit_write_y(). Based upon feedback from Sam Ravnborg. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Correct conventions comments. %o4 and %o5 were swapped, %g3 was not documented. Use r_TMP instead of r_SKB_DATA + r_OFF where possible in assembler stubs. Correct discussion of %o4 and %o5 in one of bpf_jit_compile()'s comments. Based upon feedback from Richard Mortimer. Signed-off-by: NDavid S. Miller <davem@davemloft.net>
