0002 patch is minor refactoring code to remove duplicate macro.
0003 patch is to add support arm64 raw syscalls numbers.
0004 patch is to document clang configuration so that can easily use
this program on both x86_64 and aarch64 platforms.

That's great! Thanks for advices, Mathieu & Suzuki.

Except the up mentioned issue, this patch looks good to me.
After applying this patch though I can see Coresight devices
under /sys/bus/coresight, but I cannot capture ETM trace data by
using below two commands:
perf record -e cs_etm/@ec036000.etf/ --per-thread ./main
perf record -e cs_etm/@ec033000.etr/ --per-thread ./main
I checked perf report command with '-D' option, I can see the
perf.data file doesn't contain any trace data from ETM. could you
tell me which test command you are using? At my side I will debug a
bit on my Hikey960 board and will keep you posted if find anything.

Thanks a lot for explaination, Marc.

ruggling to understand how you can set
the interrupt affinity for virtio device.
Do you set the physical interrupt affinity to CPU0/1 in host OS and
forward it to guest OS? Or set interrupt affinity in guest OS (I
tried on Juno board to set irq affinity in guest OS from
'/proc/irq/xxx/smp_affinity' but failed)? Or this is accomplished by
user space tool (lkvm or qemu)?
Sorry if I am asking a stupid question :)

The function kvm_vgic_inject_irq() is not only used by PPIs but also can
be used to inject interrupt for SPIs; this patch improves comment for
argument @cpuid to reflect support SPIs as well.

Looks good to me and tested on my Hikey board
to print string for instruction types.
This patch is to set branch instruction flags for instruction range
packet.
