If you could also provide your exact .config, I could see whether I

Builds perfectly fine with 5.4.0 here.
Thank you for testing.
I wonder whether I indeed missed something. I have switched to 5.4.0
again (from 9.3.0) and rechecked, a build issue was still present.
I even downloaded 5.4.0 sources and built them to try to build Xen, and
got the same effect. What I noticed is that for non-debug builds the
build issue wasn't present.
Then I decided to build today's staging
(414be7b66349e7dca42bc1fd47c2b2f5b2d27432 xen/memory: Fix compat
XENMEM_acquire_resource for size requests) instead of 9-day's old one when
I had initially reported about that build issue
(7ba2ab495be54f608cb47440e1497b2795bd301a x86/p2m: Fix
paging_gva_to_gfn() for nested virt). Today's staging builds perfectly
fine with 5.4.0.
It seems that commit in the middle
(994f6478a48a60e3b407c7defc2d36a80f880b04 xsm/dummy: harden against
speculative abuse) indirectly fixes that weird build issue with 5.4.0...
