Merge branch 'bpf-volatile-compare'
Alexei Starovoitov says:
====================
bpf: volatile compare
From: Alexei Starovoitov <[email protected]>
v2->v3:
Debugged profiler.c regression. It was caused by basic block layout.
Introduce bpf_cmp_likely() and bpf_cmp_unlikely() macros.
Debugged redundant <<=32, >>=32 with u32 variables. Added cast workaround.
v1->v2:
Fixed issues pointed out by Daniel, added more tests, attempted to convert profiler.c,
but barrier_var() wins vs bpf_cmp(). To be investigated.
Patches 1-4 are good to go, but 5 needs more work.
