Those patches prepare BPF ant its JITs for removal of VLAN_TAG_PRESENT.
The set depends on "Preparation for VLAN_TAG_PRESENT cleanup" patchset.

The series is supposed to be bisect-friendly and that requires temporary
insertion of #define VLAN_TAG_PRESENT in BPF code to be able to split
JIT changes per architecture.

Michał Mirosław (6):
   net/skbuff: add macros for VLAN_PRESENT bit
   net/bpf_jit: ARM: split VLAN_PRESENT bit handling from VLAN_TCI
   net/bpf_jit: MIPS: split VLAN_PRESENT bit handling from VLAN_TCI
   net/bpf_jit: PPC: split VLAN_PRESENT bit handling from VLAN_TCI
   net/bpf_jit: SPARC: split VLAN_PRESENT bit handling from VLAN_TCI
   net/bpf: split VLAN_PRESENT bit handling from VLAN_TCI

Please add a proper changelog to all the individual patches, right now
they have none. Also, how was this runtime tested? Did you run BPF selftest
suite with them? Seems like they weren't even compile tested properly
given the kbuild bot barking on sparc ...

Compile bot is barking because it doesn't have patches, which this set depends on.
Sorry about that.
