[PATCH 00/10] FLASK updates: MSI interrupts, cleanups
This patch set adds XSM security labels to useful debugging output
locations, and fixes some assumptions that all interrupts behaved like
GSI interrupts (which had useful non-dynamic IDs). It also cleans up the
policy build process and adds an example of how to use the user field in
the security context.
Debug output:
[PATCH 01/10] xsm: Add security labels to event-channel dump
[PATCH 02/10] xsm:
