Subject: [PATCH bpf-next 0/2] BPF kselftest cross-build/RISC-V fixes

From: Björn Töpel <bjorn@...osinc.com>

This series has two minor fixes, found when cross-compiling for the
RISC-V architecture.

Some RISC-V systems do not define HAVE_EFFICIENT_UNALIGNED_ACCESS,
which made some of tests bail out. Fix the failing tests by adding
F_NEEDS_EFFICIENT_UNALIGNED_ACCESS.

...and some RISC-V systems *do* define
HAVE_EFFICIENT_UNALIGNED_ACCESS. In this case the autoconf.h was not
correctly picked up by the build system.


Cheers,
Björn
