Description
I am trying to lift an andoird kernel binary but I am facing the following error:
Missing type for register number: 51204
storeRegister() unhandled reg.
Missing type for register number: 51204
storeRegister() unhandled reg.
[capstone2llvmir]: Missing type for register number: 245
Is there any direct way to fix this? Also how can I locate the missing registers and add the definition to the tool?

Research direction
Start with the capstone2llvmir register-handling path, especially storeRegister(), and reproduce the error using the Android kernel binary described in the report. Trace how register numbers are mapped to types and identify where the missing definitions should be added; done means the binary lifts without the reported unhandled-register and missing-type messages.
