module_free()/vfree() takes care of details, we no longer need a wrapper
and a work_struct.

filter: bpf_jit_comp: refactor and unify BPF JIT image dump output2013-03-21T21:25:56ZDaniel Borkmann2013-03-21T21:22:03Zurn:sha1:79617801ea0c0e6664cb497d4c1892c2ff407364
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.

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.
