#     Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 fixes from Thomas Gleixner:
#      "A set of fixes for x86:
#     
#        - Fix the bogus detection of 32bit user mode for uretprobes which
#          caused corruption of the user return address resulting in
#          application crashes. In the uprobes handler in_ia32_syscall() is
#          obviously always returning false on a 64bit kernel. Use
#          user_64bit_mode() instead which works correctly.
#     
#        - Prevent large page splitting when ftrace flips RW/RO on the kernel
#          text which caused iTLB performance issues. Ftrace wants to be
#          converted to text_poke() which avoids the problem, but for now
#          allow large page preservation in the static protections check when
#          the change request spawns a full large page.
#     
#        - Prevent arch_dynirq_lower_bound() from returning 0 when the IOAPIC
#          is configured via device tree. In the device tree case the GSI 1:1
#          mapping is meaningless therefore the lower bound which protects the
#          GSI range on ACPI machines is irrelevant. Return the lower bound
#          which the core hands to the function instead of blindly returning 0
#          which causes the core to allocate the invalid virtual interupt
#          number 0 which in turn prevents all drivers from allocating and
#          requesting an interrupt.
#     
#        - Remove the bogus initialization of LDR and DFR in the 32bit bigsmp
#          APIC driver. That uses physical destination mode where LDR/DFR are
#          ignored, but the initialization and the missing clear of LDR caused
#          the APIC to be left in a inconsistent state on kexec/reboot.
#     
#        - Clear LDR when clearing the APIC registers so the APIC is in a well
#          defined state.
#     
#        - Initialize variables proper in the find_trampoline_placement()
#          code.
#     
#        - Silence GCC( build warning for the real mode part of the build"
#     
#     * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
