HI Gregory,

walk_system_ram_res_rev() erroneously discards resource flags when passing the information to the callback.
This causes systems with IORESOURCE_SYSRAM_DRIVER_MANAGED memory to have these resources selected during kexec to store kexec buffers if that memory happens to be at placed above normal system ram.
Sorry about that. I haven't checked IORESOURCE_SYSRAM_DRIVER_MANAGED memory carefully, wondering if res could be set as 'IORESOURCE_SYSTEM_RAM | IORESOURCE_BUSY' plus IORESOURCE_SYSRAM_DRIVER_MANAGED in iomem_resource tree.
Anyway, the change in this patch is certainly better. Thanks.
Can we get more test cases in the respective module, please?
