Subject: mm/memory_hotplug: pass online_type to online_memory_block() via arg
Date: Sun, 12 Jul 2026 11:44:57 -0400

Modify online_memory_block() to accept the online type through its arg
parameter rather than calling mhp_get_default_online_type() internally.

This prepares for allowing callers to specify explicit online types.

Update the caller in add_memory_resource() to pass the default online
type via a local variable.

No functional change.
