From: Sean Christopherson Date: Tue, 22 Jun 2021 20:05:15 +0000 (-0700) Subject: KVM: selftests: Use "standard" min virtual address for Hyper-V pages X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=95be3709ff4e3af848c285ebddea9916a24d6d0f;p=linux.git KVM: selftests: Use "standard" min virtual address for Hyper-V pages Use the de facto standard minimum virtual address for Hyper-V's hcall params page. It's the allocator's job to not double-allocate memory, i.e. there's no reason to force different regions for the params vs. hcall page. This will allow adding a page allocation helper with a "standard" minimum address.
