Is this really a full header sync? I'd have expected it to
have non-ARM changes
With current implementation the vgic is initialized implicitly,
on-demand. This patch forces the init in the vgic finalize function.
At that point all the dimensioning parameters are known.
A new group/attribute in VGIC KVM device is used for that:
KVM_DEV_ARM_VGIC_GRP_CTRL/KVM_DEV_ARM_VGIC_CTRL_I
This patch forces vgic initialization in the vgic realize function.
It uses a new group/attribute that allows such operation.
This earlier initialization allows, for example, to setup VFIO
signaling and irqfd after vgic initialization, on a reset notifier.

It has always been a page header, not a block header. Once there, the
flag argument was only passed to make a bit or with it, just do the or

No need to pass it through all the callers. Once there, update

Hi
(Li special edition)
Current migration code returns number of bytes transferred and from
there we decide if we.have sent something or not. Problem, we need
two results: number of pages written, and number of bytes written
(depending on compression, zero pages, etc, it is not possible to
deriv

It used to be an int, but then we can't pass directly the
bytes_transferred parameter, that would happen later in the series.

Add main working flow feature and loading elf64 tilegx binary feature,
based on Linux kernel tilegx 64-bit implementation.
After this patch, qemu can successfully load elf64 tilegx binary for
linux-user, and the working flow reaches 1st instruction "__start".
