I asked the same here: https://lore.kernel.org/r/[email protected] IIRC Baoquan said that there is a 1MB reserved for x86 anyway in the lower part, so that's equivalent in practice to starting from CRASH_ALIGN. Anyway, I agree the commit log should describe this. -- Catalin _______________________________________________ kexec mailing list [email protected] http://lists.infradead.org/mailman/listinfo/kexec
