Merge branch 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 apic updates from Thomas Gleixner: "This update provides: - Cleanup of the IDT management including the removal of the extra tracing IDT. A first step to cleanup the vector management code. - The removal of the paravirt op adjust_exception_frame. This is a XEN specific issue, but merged through this branch to avoid nasty merge collisions - Prevent dmesg spam about the TSC DEADLINE bug, when the CPU has disabled the TSC DEADLINE timer in CPUID. - Adjust a debug message in the ioapic code to print out the information correctly" * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (51 commits) x86/idt: Fix the X86_TRAP_BP gate x86/xen: Get rid of paravirt op adjust_exception_frame x86/eisa: Add missing include x86/idt: Remove superfluous ALIGNment x86/apic: Silence "FW_BUG TSC_DEADLINE disabled due to Errata" on CPUs without the feature x86/idt: Remove the tracing IDT leftovers x86/idt: Hide set_intr_gate() x86/idt: Simplify alloc_intr_gate() x86/idt: Deinline setup functions x86/idt: Remove unused functions/inlines x86/idt: Move interrupt gate initialization to IDT code x86/idt: Move APIC gate initialization to tables x86/idt: Move regular trap init to tables x86/idt: Move IST stack based traps to table init x86/idt: Move debug stack init to table based x86/idt: Switch early trap init to IDT tables x86/idt: Prepare for table based init x86/idt: Move early IDT setup out of 32-bit asm x86/idt: Move early IDT handler setup to IDT code x86/idt: Consolidate IDT invalidation ...
