All the last 3 arguments of KiIpiSendPacket should be the 3 parameters iirc.

KPRCB IPI Stuff:

+0x8a0 CurrentPacket    : [3] Ptr32 Void => The last 3 parameters of 
KiIpiSendPacket, which are also the 3 parameters of KIPI_WORKER go here.
   +0x8ac TargetSet        : Uint4B  => Processors (1st argument) goes here.
   +0x8b0 WorkerRoutine    : Ptr32   => PKIPI_ROUTINE goes here.
   +0x8b4 IpiFrozen        : Uint4B => IPI State flags if IPIs are 
frozen by CPU Freeze functions
