Merge branch 'x86-asmlinkage-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 asmlinkage (LTO) changes from Peter Anvin: "This patchset adds more infrastructure for link time optimization (LTO). This patchset was pulled into my tree late because of a miscommunication (part of the patchset was picked up by other maintainers). However, the patchset is strictly build-related and seems to be okay in testing" * 'x86-asmlinkage-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, asmlinkage, xen: Fix type of NMI x86, asmlinkage, xen, kvm: Make {xen,kvm}_lock_spinning global and visible x86: Use inline assembler instead of global register variable to get sp x86, asmlinkage, paravirt: Make paravirt thunks global x86, asmlinkage, paravirt: Don't rely on local assembler labels x86, asmlinkage, lguest: Fix C functions used by inline assembler
