This is an attempt to resurrect Sumit's old patch series [1] that
allowed us to use the arm64 pseudo-NMI to get backtraces of CPUs and
also to round up CPUs in kdb/kgdb. The last post from Sumit that I
could find was v7, so I called this series v8. I haven't copied all of
his old changelongs here,

There are many places that enable and disable AER interrput, so move
them into helpers.

PCIe service that shares IRQ with PME may cause spurious wakeup on
system suspend.
PCIe Base Spec 5.0, section 5.2 "Link State Power Management" states
that TLP and DLLP transmission is disabled for a Link in L2/L3 Ready

PCIe service that shares IRQ with PME may cause spurious wakeup on

Since AER is conditionally disabled in previous patch, also apply the
same logic to disable DPC which depends on AER to work.

Hello Michael,
I was looking into the Bug: 199106
(https://bugzilla.linux.ibm.com/show_bug.cgi?id=199106).
In the Bug, Mellanox driver was timing out when enabling SRIOV device.
I tested, Alexey's patch and it fixes the issue with Mellanox driver.
The down side
to Alexey's fix is that even
Layerscape has PME interrupt, which can be use as linkup notifer.
Set CFG_READY bit when linkup detected.
