Subject: [PATCH v17 03/24] KVM: x86: Select KVM_GENERIC_PRIVATE_MEM directly from KVM_SW_PROTECTED_VM
Date: Tue, 29 Jul 2025 15:54:34 -0700	[thread overview]
Message-ID: <20250729225455.670324-4-seanjc@google.com> (raw)
In-Reply-To: <20250729225455.670324-1-seanjc@google.com>

Now that KVM_SW_PROTECTED_VM doesn't have a hidden dependency on KVM_X86,
select KVM_GENERIC_PRIVATE_MEM from within KVM_SW_PROTECTED_VM instead of
conditionally selecting it from KVM_X86.

No functional change intended.
