Hi，marc
https://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git/log/?h=arm64/nmi
During the testing of this set of vNMI patches, it was discovered that
vNMI do not support live
migration. The reason is that GICD_INMIR/GICR_INMIR0 have not been
migrated, causing
irq->nmi to reset to 0 after migration. Therefore, to resolve this
issue, we need to complete the
migration of GICD_INMIR/GICR_INMIR0. This set of patches does not seem
to have been uploaded
to the mainline. I was wondering if these are scheduled for upload to
the mainline?
Thanks,
Jinqian

There patches are *dead*, and will *not* be upstreamed as such. You
can tell from the date and the base commit that they are old and
unmaintained.
Please do not pick random branches from my tree.
Thanks,

Noted with thanks — will avoid referencing outdated branches in the future.
