The Arm zImage loader currently computes the kernel load address and
places the DTB/initrd in one local flow. The hardware-domain memory
allocator needs to reuse those placement rules before it chooses bank 0,
but open-coding the same calculations there would make the fix harder to
audit.
Split the existing logic into small helpers:
- kernel_zimage_place_in_bank() computes the zImage load address for a
given bank.
- first_bank_can_fit_modules() checks the aggregate first-bank
footprint.
- find_dtb_initrd_placement() chooses the DTB/initrd location within a
known bank and kernel range.
Rename place_modules() to place_dtb_initrd() so the code distinguishes
the kernel image from the DTB/initrd placement area. Also update the
comments linking the hypervisor and toolstack placement paths.
While moving the code, spell the 2MB alignment mask with MB(2) rather
than open-coding (2 << 20). This is mechanical and keeps the generated
value unchanged.
The caller still panics in the same cases as before, so this is intended
to be behavior preserving.

it never got wired into any toolstacks. In the meantime, how we handle CPUID

Decompressing the kernel is necessary to inspect the ELF notes, but the
dombuilder will gunzip() secondary modules too. Specifically gunzip(), no
other decompression algorithms.
This may have been necessary in the dim and distant past, but it is broken
today. Linux specifically supports concatenating CPIO fragments of differing
compressions, and any attempt to interpret it with a single algorithm may
corrupt later parts.
This was an unexpected discovery while trying to test Xen's gunzip()
logic (Xen as a PVH guest, with a gzipped XTF kernel as dom0).
Interpreting secondary modules should be left as an exercise to the guest.
This reduces work done in dom0.

xc_cpuid_apply_policy() provides compatibility for migration of a pre-4.14 VM
where no CPUID data was provided in the stream.
It guesses the various max-leaf limits, based on what was true at the time of
writing, but this was not correctly adapted when speculative security issues
forced the advertisement of new feature bits. Of note are:
* LFENCE-DISPATCH, in leaf 0x80000021.eax
* BHI-CTRL, in leaf 0x7[2].edx
In both cases, a VM booted on a security-patched Xen 4.13, and then migrated
on to any newer version of Xen on the same or compatible hardware would have
these features stripped back because Xen is still editing the cpu-policy for
sanity behind the back of the toolstack.
For VMs using BHI_DIS_S to mitigate Native-BHI, this resulted in a failure to
restore the guests MSR_SPEC_CTRL setting:
(XEN) HVM d7v0 load MSR 0x48 with value 0x401 failed

xc_dom_alloc_segment() is passed a size in bytes, calculates a size in pages

This causes the module information given to the guest (MB, or PVH) to have
incorrect sizes; specifically, sizes rounded up to the next page.
This in turn is problematic for Xen. When Xen finds a gzipped module, it
peeks at the end metadata to judge the decompressed size, which is a -4

The procedure used to customize the domain CPU policy is broken when
toolstack tries to set leaves (with subleaves) that the hypervisor didn't
need to serialise (i.e: because they where empty subleaves).
During typical domain creation xg does the following:
1. Probe Xen for max #leaves that a policy may have
2. Allocate memory for that many leaves
3. Tell the hypervisor to dump the policy in the allocated buffer
4. Deserialise it
5. Modify it
6. Reserialise it
7. Send it back to Xen
The problem is that (3) overrides nr_leaves, which then makes (6) fail in
the case where (5) has added subleaves that Xen understands but didn't need
to serialize on (3).
The fix uses an opaque CPU policy object so we can (a) avoid probing Xen
for sizes, and (b) trivially have knowledge of the actual size of the
buffer.

For unstable libs, we only needs the symver to be different from a
