[PATCH] x86: add a bootparameter to reserve high linear address space
Add a boot parameter to reserve high linear address space for hypervisors. This is necessary to allow dynamically loaded hypervisor modules, which might not happen until userspace is already running, and also provides a useful tool to benchmark the performance impact of reduced lowmem address space.
