2017-06-13x86/boot/64: Rename init_level4_pgt and early_level4_pgtKirill A. Shutemov
With CONFIG_X86_5LEVEL=y, level 4 is no longer top level of page tables. Let's give these variable more generic names: init_top_pgt and early_top_pgt. Signed-off-by: Kirill A.

2017-02-07xen/pvh: Bootstrap PVH guestBoris Ostrovsky
Start PVH guest at XEN_ELFNOTE_PHYS32_ENTRY address. Setup hypercall page, initialize boot_params, enable early page tables. Since this stub is executed before kernel entry point we cannot use variables in .bss which is cleared by kernel. We explicitly place variables that are initialized here into .data. While adjusting xen_hvm_init_shared_info() make it use cpuid_e?x() instead of cpuid() (wherever possible).
