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
