Currently we always use memory map[] to help hvmloader construct e820 table
but hvmloader may have relocated RAM to support mmio allocation or just
populated ram to ensure we can have enough room to load ovmf. Anyway we
need to sync these changes into memory map[].

Git blame shows that the change that crashes hvmloader was part of the

Currently, the event channel rebind code is gated with the presence of
the vector callback.
The virtual interrupt controller on ARM has the concept of per-CPU
interrupt (PPI) which allow us to support per-VCPU event channel.
Therefore there is no need of vector callback for ARM.

Most other workloads seem to be stable, however, I do see similar crashes

x86-specific hook cleans up the pirq-emuirq mappings, destroys all ioreq
servers and and replaces the shared_info frame with an empty page to support
subsequent XENMAPSPACE_shared_info call.
ARM-specific hook is -ENOSYS for now.

The privcmd code is mixing the usage of GFN and MFN within the same
functions which make the code difficult to understand when you only work
with auto-translated guests.
The privcmd driver is only dealing with GFN so replace all the mention
of MFN into GFN.
The ioctl structure used to map foreign
The PV driver xen-fbfront is only dealing with GFN and not MFN. Rename
all the occurence of MFN to GFN.
Also take the opportunity to replace to usage of pfn_to_gfn by
page_to_pfn.

ARM guests are assimilated to HVM guest on ARM. The current
implementation is assuming a 1:1 mapping which is only true for DOM0 and
may not be at all in the future.
Furthermore, all the helpers but arbitrary_virt_to_machine are used in
x86 specific code (or only compiled for).
The helper arbitra
All the caller of xen_tmem_{get,put}_page have a struct page * in hand
and call pfn_to_gfn for the only benefits of these 2 functions.
Rather than passing the pfn in parameter, pass directly the page and use
directly page_to_gfn.

HVM_PARAM_CONSOLE_PFN is used to retrieved the console PFN for HVM
guest. It returns a PFN (aka GFN) and not a MFN.
Furthermore, use directly virt_to_gfn for both PV and HVM domain rather
than doing a special case for each of the them.

The swiotlb is required when programming a DMA address on ARM when a

In this case, the DMA address should always be equal to the machine address.
For DOM0 memory, Xen ensure it by have an identity mapping between the
