When I use kexec to change the kernel on Xen, it always appears an error “could
not get memory layout”? Why? Does it support to boot without bios on Xen with
kexec?

Hi Jens,
this series moves various helpers related to merging based on physical
addresses from the public headers into block/, moves the Xen special
case from arch hooks into common code, cleans up the code a bit, and
removes not nessecary includes from the block headers.
The actual recaculation of segments in __blk_recalc_rq_segments will
do this check, so there is no point in forcing it if we know it won't
succeed.

The wording here is confusing. It should have been written as:

This series goes through x86 code to make CONFIG_HVM work.
With this series, it is possible to build Xen with PV support only.
Running `xl info` on a host with PV only Xen:
root@lcy2-dt108:~# xl info
host : lcy2-dt108
release: 4.17.0-0.bpo.1-amd64

Previously PoD target was unconditionally set for both PV and HVM
guests, but in fact PoD has always been an HVM (now PVH as well) only
feature.
