Merge branch 'x86-kaslr-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perparatory x86 kasrl changes from Ingo Molnar: "This contains changes from the ongoing KASLR work, by Kees Cook. The main changes are the use of a read-only IDT on x86 (which decouples the userspace visible virtual IDT address from the physical address), and a rework of ELF relocation support, in preparation of random, boot-time kernel image relocation." * 'x86-kaslr-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, relocs: Refactor the relocs tool to merge 32- and 64-bit ELF x86, relocs: Build separate 32/64-bit tools x86, relocs: Add 64-bit ELF support to relocs tool x86, relocs: Consolidate processing logic x86, relocs: Generalize ELF structure names x86: Use a read-only IDT alias on all CPUs
