f08e9b6a73 vmm: device_manager: Return PciDeviceInfo from a hotplugged device
In order to provide the device name and PCI b/d/f associated with a
freshly hotplugged device, the hotplugging functions from the device
manager return a new structure called PciDeviceInfo.

3f18f93f40 docs: Add a guide for testing on AArch64
The support of AArch64 is in very early stage. The steps in building and
runing on X86 and AArch64 can not align well yet. Adding AArch64 content
to README.md would produce much divergence.
Adding a guide in docs/ folder could be a better way to start now.

bf37ebdcb6 arch: x86_64: Add 5th level of paging when needed
For correctness, when the CPUID supports the LA57 feature, the VMM sets
the CR4.LA57 register, which means a fifth level of page table might be
needed. Even if it's not needed because the kernel should not use
addresses over 1GiB, it's better to define this new level anyway.

This patch only applies to the Linux boot codepath, which means it
affects both vmlinux without PVH and bzImage binaries. The bzImage
does not need this since the page tables and CR4 registers are set in
the decompression code from the kernel.

And for vmlinux with PVH, if we follow the PVH specification, the kernel
must be responsible for setting things up, but the implementation is
missing. This means for now that PVH does not support LA57 with 5 levels
of paging.

In order to workaround a Linux bug that happens when we place devices at

we reduce the MMIO address space by one 4k page. This way, nothing gets
allocated in the last 4k of the address space, which is negligible given
the amount of space in the address space.
