[PATCH 0/9] Improve trap handling for nested traps

[Anup Patel]

Nested traps will be a common when dealing with RAS error traps so
this series improves trap handling for nested traps by introducing
a linked-list based trap context chain.

These patches can also be found the trap_handling_imp_v1 branch at
https://github.com/avpatel/opensbi.git
