[PATCH v2 15/20] KVM: selftests: Use TEST_EXTRA region in x86's smaller MAXPHYADDR test

From: Sean Christopherson <seanjc@google.com>
Date: 2026-09-02 16:41:46
Also in: kvm, kvm-riscv, kvmarm, linux-riscv, lkml, loongarch
Subsystem: kernel selftest framework, kernel virtual machine (kvm), kernel virtual machine for x86 (kvm/x86), the rest · Maintainers: Shuah Khan, Shuah Khan, Paolo Bonzini, Sean Christopherson, Linus Torvalds

Use the TEST_EXTRA region/memslot for x86's smaller MAXPHYADDR test instead
of a custom memslot, so that the primary vm_phy_pages_alloc() APIs can be
reworked to take a region type instead of a raw memslot.

For all intents and purposes, no functional change intended, as
vm_add_extra_mem_region() is barely more than a wrapper for
vm_userspace_mem_region_add().
