Research direction
Start by reading the linked Linux exception-tables documentation and the issue's description of get_user fault recovery. Determine how Binary Ninja's instruction representation could express the access and recovery relationship; done means a reviewed design and API instruction specification that captures this documented control flow.
Written by the indexing model from the issue text.
Description
In the Linux kernel, there is a generic fault-recovery mechanism [1] that is used in things like get_user (read data through a user-space pointer) to recover from a faulting memory access. The access is implemented in assembly, and a recovery code is also specified in the assembly, and a table entry is added to a seperate section the "links" the two. It would be nice if Binary Ninja were aware of these special and documented control-flows, and had an instruction for expressing them. I think this type of instruction would be more generally useful in the future.
