Message-Id: <20131230184100.D99DCA7E@viggo.jf.intel.com> Date: Mon, 30 Dec 2013 10:41:00 -0800 From: Dave Hansen <dave@...1.net> To: linux-kernel@...r.kernel.org Cc: x86@...nel.org, Dave Hansen <dave@...1.net> Subject: [PATCH 11/12] x86 Kconfig: move paravirt under virtualization From: Dave Hansen <dave.hansen@...ux.intel.com> Right now, there is a "Enable paravirtualization code" option in the "Processor Features" menu, which means Xen. There is also a group of paravirtualization options specific to KVM under the top-level "Virtualization" menu. This creates a new hypervisor-indemendent arch/x86/Kconfig.virt file, and moves the "Virtualization" menu to be defined in there. This also removes the very counterintuitive references to lguest/vhost code *from* kvm-specific code. This also removes the silly: depends on HAVE_KVM || X86 dependency. It makes zero sense to have entried defined in arch/x86 depend on x86.
