Subject: [PATCH 06/13] x86/kconfig/64: Enable the KVM host in the defconfig
Date: Thu, 15 May 2025 15:27:12 +0200	[thread overview]
Message-ID: <20250515132719.31868-7-mingo@kernel.org> (raw)
In-Reply-To: <20250515132719.31868-1-mingo@kernel.org>

These days all distros enable KVM, and since the x86 defconfig
aims to be a distro kernel work-alike with fewer drivers and
a shorter build time, enable the KVM host in the defconfig too.
