Also this patch is problematic on LoongArch.
The original patch is to search physical cpuid rather than logic cpuid.
We want to make ipi module better and better, however now it comes back
to initial state at the beginning :(
Isn't arch_id the "physical id" you want? "cs->cpu_index" is the logical ID
for QEMU.
arch_id is setup by arch code, like APIC ID for x86.
I had come across the old ipi_getcpu implementation, and I'm sure we were
looking at arch_id as well.
So, where is implementation code for function get_arch_id() looking for
vcpu with physical index?

hw/intc/loongson_ipi: Replace ipi_getcpu with cpu_by_arch_id
cpu_by_arch_id is doing the same thing as our ipi_getcpu logic.
