[PATCH] usr/include: openrisc: don't HDRTEST bpf_perf_event.h

[PATCH] usr/include: openrisc: don't HDRTEST bpf_perf_event.h

[Randy Dunlap]

Since openrisc does not support PERF_EVENTS, omit the HDRTEST of
bpf_perf_event.h for arch/openrisc/.

Fixes a build error:
usr/include/linux/bpf_perf_event.h:14:28: error: field 'regs' has incomplete type

This looks ok to me, but do you have any pointer of how to reproduce this?

All I did was 'make allmodconfig' or 'make allyesconfig'. Either of them cause
this error.

Thanks, I was just now able to figure this out after some more reading of
usr/include/Makefile.  As long as I have CONFIG_UAPI_HEADER_TEST enabled the
HDRTEST's will run and I could produce this.

I suppose this should go via the Yamada-san's make tree. So:

Where can I get openrisc compiler that enables CONFIG_CC_CAN_LINK?

Never mind.
I downloaded a one from
https://github.com/stffrdhrn/or1k-toolchain-build/releases

Hmm, I did not observe an error like that.

Instead, I got a different error message.

Does HDRTEST use the #include files from the header that is being tested?

usr/include/linux/bpf_perf_event.h #includes <asm/bpf_perf_event.h>
(from usr/include/ ??) which #includes <asm-generic/bpf_perf_event.h>
(from usr/include/ ??) which #includes <linux/ptrace.h> (from usr/include/ ??)
which #includes <linux/types.h>.  I don't see this problem in my builds.

I do still continue to see this failure:

  HDRTEST usr/include/linux/bpf_perf_event.h
In file included from <command-line>:
./usr/include/linux/bpf_perf_event.h:14:28: error: field 'regs' has incomplete type
