Subject: bpf: fix build issues on um due to mising bpf_perf_event.h
From: Daniel Borkmann <daniel@xxxxxxxxxxxxx>
commit ab95477e7cb35557ecfc837687007b646bab9a9f upstream.
[ Note, this is a Git cherry-pick of the following commit:
a23f06f06dbe ("bpf: fix build issues on um due to mising bpf_perf_event.h")
... for easier x86 PTI code testing and back-porting. ]
Since c895f6f703ad ("bpf: correct broken uapi for
BPF_PROG_TYPE_PERF_EVENT program type") um (uml) won't build
on i386 or x86_64:
[...]
CC init/main.o
In file included from ../include/linux/perf_event.h:18:0,
from ../include/linux/trace_events.h:10,
from ../include/trace/syscall.h:7,
from ../include/linux/syscalls.h:82,
from ../init/main.c:20:
../include/uapi/linux/bpf_perf_event.h:11:32: fatal error:
asm/bpf_perf_event.h: No such file or directory #include
<asm/bpf_perf_event.h>
[...]
Lets add missing bpf_perf_event.h also to um arch. This seems
to be the only one still missing.
Fixes: c895f6f703ad ("bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type")
