-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
Use the new __TRAILING_OVERLAP() helper to fix the following warning:
include/hyperv/hvgdk_mini.h:581:25: warning: structure containing a flexible
array member is not at the end of another structure
[-Wflex-array-member-not-at-end]
This helper creates a union between a flexible-array member (FAM) and a
set of MEMBERS that would otherwise follow it.
This overlays the trailing MEMBER u64 gva_list[]; onto the FAM
struct hv_tlb_flush_ex::hv_vp_set.bank_contents[], while keeping
the FAM and the start of MEMBER aligned.
The static_assert() ensures this alignment remains, and it's
intentionally placed inmediately after the related structure --no
blank line in between.

Applied. I fixed a typo in the commit message ("inmediately" ->
"immediately").
Awesome. :)
Thanks
