Certain HMI's such as malfunction error propagate through
all threads/core on the system. If a thread was offline
prior to us crashing the system and jumping to the kdump
kernel, bad things happen when it wakes up due to an HMI
in the kdump kernel.
There are several possible ways to solve this pro

When pseries SR-IOV is enabled and after a PF driver
has resumed from EEH, platform has to be notified
of the event so the child VFs can be allowed to
resume their normal recovery path.
This patch makes the EEH operation allow unfreeze
platform dependent code and adds the call to
pseries EEH code.
When enabling SR-IOV in pseries platform,
the VF bar properties for a PF are reported on
the device node in the device tree.
This patch adds the IOV Bar resources to Linux

when configuring SR-IOV by PF driver.

So this patch shortens it by using an array (fsl_ssi_regvals,

two macros (TX and RX) to replace the wrapper structure. This

While reviewing the code I found that the flush assumes all
pages are of mmu_linear_psize, which is not correct. The patch
uses find_linux_pte to find the right page size and uses that
for launching the ATSD invalidation. A new helper is added
to abstract the invalidation from the various notifiers
