Subject: [PATCH 2/2] Remove depends on X86_32 from PARAVIRT & PARAVIRT_GUEST
Date: Tue, 22 Jan 2008 16:52:40 -0200 [thread overview]
Message-ID: <20080122185239.GZ7338@blackpad> (raw)
In-Reply-To: <20080122185018.GY7338@blackpad>
With this, the paravirt_ops code can be enabled on x86_64 also.
Each guest implementation (Xen, VMI, lguest) now depends on X86_32. The
dependencies can be dropped for each one when they start to support
x86_64.

This changes the kernel so it can modify itself when it is run
under a hypervisor, potentially improving performance significantly
