TLB dropins require updates to the CBR instruction istatus field. This is needed to resolve race conditions in the chip. The code currently uses the user address of the CBR. This works but opens up additional endcases related to stealing of contexts and accessing the CBR from tasks that do not have access to the user address space. (Some of this non-user task access is debug code that is not currently being pushed to the community). User CBRs are also directly accessible using the kernel mapping of the CBR. Change the TLB dropin code to use the the kernel mapping of the CBR.
