    Pull arm64 fixes from Catalin Marinas:
     "Fix SDEI (software delegated exception interface) handlers taking
      nested exceptions (looping on the KPTI trampoline vectors and
      clobbering the interrupted context's exception registers), TPIDR2_EL0
      preservation across CPU suspend, a kexec_file_load() memory leak and
      an overflow in the /dev/mem valid_mmap_phys_addr_range() check:

       - Fix nested exceptions taken by SDEI event handlers.

         With KPTI, an event interrupting user space left the trampoline
         vectors installed and any exception in the handler looped forever.
         Also save and restore ELR/SPSR/ESR/FAR around the handler since an
         event can interrupt exception entry or return where these registers
         are live

       - Save and restore TPIDR2_EL0 across CPU suspend.

         Its value is UNKNOWN after a warm reset and the task initiating
         suspend could return to user space with a corrupted value

       - Fix an overflow in valid_mmap_phys_addr_range() allowing /dev/mem
         to map out-of-range PFNs

       - Fix an elf_headers memory leak in the kexec_file segment placement
         retry loop"
