We currently run IST interrupt handlers on the IST stack. Changing it may simplify a few things. See patch 2 for details.
Patch 1 is a fix for a not-quite-bug in uprobes that Oleg noticed that would be exposed by patch 2.
Andy Lutomirski (2): x86, entry: Switch stacks on a paranoid entry from userspace uprobes, x86: Fix _TIF_UPROBE vs _TIF_NOTIFY_RESUME
