| It's not really expected - we factorize the CPU IDs (which are logical)
| so that the boot CPU is 0. But relying on cpu==0 is the boot cpu is not
| clean and the resulting code is harder to read.
Perhaps we need some is_bsp_cpu() helper? Though to cover all x86 places
we need some efforts to apply :/
