[bpf-next,v2,0/4] Various RISC-V BPF improvements

Message

Unfortunately selftest/bpf does not build for RV64. This series fixes
that.

* JIT requires more iterations to converge
* Some Makefile issues
* bpf_tracing.h was missing RISC-V macros for PT_REGS

More details are in each commit.

There are still many failing tests, but this is a start.


Cheers,
Björn

v1->v2: A newline sneaked into the Makefile for patch 4, which broke the build. Removed.

Björn Töpel (4):
  riscv, bpf: Increase the maximum number of iterations
  tools build: Add RISC-V to HOSTARCH parsing
  riscv, libbpf: Add RISC-V (RV64) support to bpf_tracing.h
  selftests/bpf: Fix broken riscv build
