[Qemu-devel] [PULL v2 022/106] trace: pc: add PC_DIMM slot & address allocation

[Michael S. Tsirkin]

From: Igor Mammedov <address@hidden>

Add mhp_pc_dimm_assigned_slot & mhp_pc_dimm_assigned_address
events to trace which address and slot where assigned to
plugged in PC_DIMM device on target-i386 machine.
