[Xen-devel] [PATCH v4 1/3] efi: remove old SetVirtualAddressMap() arrangement

2019-10-23 Thread Marek Marczykowski-Górecki
Remove unused (#ifdef-ed out) code. Reviving it in its current shape won't fly because: - SetVirtualAddressMap() needs to be called with 1:1 mapping, which isn't the case at this time - it uses directmap, which may go away soon - it uses directmap, which is mapped with NX, breaking EfiRuntime
