2015-08-24 Thread Pavel Fedin
This large region is necessary for some devices like ivshmem and video cards 32-bit kernels can be built without LPAE support. In this case such a kernel will not be able to use PCI controller which has windows in high addresses. In order to work around the problem, "highmem" option is introduced.
