Hi Namhyung,
Is it possible to fix this before the updates to keep it buildable?
Maybe it's not feasible, I didn't check.
I did notice a build issue in the kvm tests after this update:
$ make O=../build/local/ summary=1 TARGETS=kvm kselftest
In file included from aarch64/aarch32_id_regs.c:14:
include/aarch64/processor.h:15:10: fatal error: asm/brk-imm.h: No such
file or directory
15 | #include <asm/brk-imm.h>
But I tried the same on v6.13-rc1 and got a different error, so I don't
know if it's any worse.
Thanks
James

I suspect it's an unrelated issue. This fix is about generating
descriptions of the flags for perf trace beautifier.
The below is the only change I made in this series for arm64.
Thanks,

Looked like some kind of stale build issue. A clean fixed it but I
wasn't able to reproduce it.
