Merge branch 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cleanups from Ingo Molnar: "A handful of cleanups: dma-ops cleanups, missing boot time kcalloc() check, a Sparse fix and use struct_size() to simplify a vzalloc() call" * 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/pci: Clean up usage of X86_DEV_DMA_OPS x86/Kconfig: Remove the unused X86_DMA_REMAP KConfig symbol x86/kexec/crash: Use struct_size() in vzalloc() x86/mm/tlb: Define LOADED_MM_SWITCHING with pointer-sized number x86/platform/uv: Fix missing checks of kcalloc() return values
