From de68e4daea9084df4c614d31e2061d5d31bf24f4 Mon Sep 17 00:00:00 2001 From: Pavel Tatashin Date: Wed, 4 Dec 2019 10:59:15 -0500 Subject: kexec: add machine_kexec_post_load() It is the same as machine_kexec_prepare(), but is called after segments are loaded. This way, can do processing work with already loaded relocation segments. One such example is arm64: it has to have segments loaded in order to create a page table, but it cannot do it during kexec time, because at that time allocations won't be possible anymore.
