| * sparc64: remove cast from output constraints in math asm statementsSam Ravnborg2014-05-181-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following asm statements generated a sparse warning: asm("addcc \n\t" : "=r" (((USItype)(r2))) warning: asm output is not an lvalue When asking on the sparse mailing list Linus replyed: " Those casts to (USItype) are all pointless to begin with (since the values are of that type already!) and they mean that the expression isn't something you can assign to (lvalue). " In the math emulation code drop all casts in the output parts of the asm statements. This fixes a lot of "warning: asm output is not an lvalue" sparse warnings in math_64.c.

| * | | net: filter: get rid of BPF_S_* enumDaniel Borkmann2014-06-011-81/+73

Currently, the code performs unnecessary encode and decode workarounds in seccomp and filter migration itself when a filter is being attached in order to overcome BPF_S_* encoding which is not used anymore by the new interpreter resp. JIT compilers. Keeping it around would mean that also in future we would need to extend and maintain this enum and related encoders/decoders. We can get rid of all that and save us these operations during filter attaching. Naturally, also JIT compilers need to be updated by this. Before JIT conversion is being done, each compiler checks if A is being loaded at startup to obtain information if it needs to emit instructions to clear A first. Since BPF extensions are a subset of BPF_LD | BPF_{W,H,B} | BPF_ABS variants, case statements for extensions can be removed at that point. To ease and minimalize code changes in the classic JITs, we have introduced bpf_anc_helper(). Tested with test_bpf on x86_64 (JIT, int), s390x (JIT, int), arm (JIT, int), i368 (int), ppc64 (JIT, int); for sparc we unfortunately didn't have access, but changes are analogous to the rest.
