Merge branch 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86/pti fixes from Thomas Gleixner: "Three fixes related to melted spectrum: - Sync the cpu_entry_area page table to initial_page_table on 32 bit. Otherwise suspend/resume fails because resume uses initial_page_table and triggers a triple fault when accessing the cpu entry area. - Zero the SPEC_CTL MRS on XEN before suspend to address a shortcoming in the hypervisor. - Fix another switch table detection issue in objtool" * 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/cpu_entry_area: Sync cpu_entry_area to initial_page_table objtool: Fix another switch table detection issue x86/xen: Zero MSR_IA32_SPEC_CTRL before suspend
