[Crash-utility] [PATCH] arm64: move irq/overflow/stackframe init to POST_VM phase
When percpu data is in vmalloc area (pcpu_page_first_chunk fallback on
large NUMA systems), arm64_kvtop() cannot translate vmalloc addresses
during POST_GDB because vt->vmalloc_start is not yet initialized by
vm_init(). Moving the stack init functions to POST_VM ensures
vt->vmalloc_start and vt->kernel_pgd are ready before readmem calls.
