Nobody used those flags. Anyone who wanted to temporarily turn on
interrupts just did
When I had lockdep turned on and dropped into kgdb I got a nice splat
on my system. Specifically it hit:
DEBUG_LOCKS_WARN_ON(current->hardirq_context)
Specifically it looked like this:
sysrq: SysRq : DEBUG
[ cut here ]
DEBUG_LOCKS_WARN_ON(current->hardirq_context)

This series was originally part of the series ("serial: Finish kgdb on
qcom_geni; fix many lockdep splats w/ kgdb") but it made sense to
split it up.
It's believed that dropping into kgdb should be more robust once these
patches are applied.
Changes in v4:
- Removed smp_mb() calls.
- Also clear
On pseries systems, performing changes to a partition's affinity
can result in altering the nodes a CPU is assigned to the
current system. For example, some systems are subject to resource
balancing operations by the operator or control software. In such
environments, system CPUs may be in node

There are still PS3 users out there. They are hobbyists who
