      Pull x86 fixes from Thomas Gleixner:
       "A set of fixes and updates for x86:
      
         - Address a swiotlb regression which was caused by the recent DMA
           rework and made driver fail because dma_direct_supported() returned
           false
      
         - Fix a signedness bug in the APIC ID validation which caused invalid
           APIC IDs to be detected as valid thereby bloating the CPU possible
           space.
      
         - Fix inconsisten config dependcy/select magic for the MFD_CS5535
           driver.
      
         - Fix a corruption of the physical address space bits when encryption
           has reduced the address space and late cpuinfo updates overwrite
           the reduced bit information with the original value.
      
         - Dominiks syscall rework which consolidates the architecture
           specific syscall functions so all syscalls can be wrapped with the
           same macros. This allows to switch x86/64 to struct pt_regs based
           syscalls. Extend the clearing of user space controlled registers in
           the entry patch to the lower registers"

      Pull x86 pti updates from Thomas Gleixner:
       "Another series of PTI related changes:
      
         - Remove the manual stack switch for user entries from the idtentry
           code. This debloats entry by 5k+ bytes of text.
      
         - Use the proper types for the asm/bootparam.h defines to prevent
           user space compile errors.
      
         - Use PAGE_GLOBAL for !PCID systems to gain back performance
      
         - Prevent setting of huge PUD/PMD entries when the entries are not
           leaf entries otherwise the entries to which the PUD/PMD points to
           and are populated get lost"

      Pull scheduler fixes from Thomas Gleixner:
       "A few scheduler fixes:
      
         - Prevent a bogus warning vs. runqueue clock update flags in
           do_sched_rt_period_timer()
      
         - Simplify the helper functions which handle requests for skipping
           the runqueue clock updat.
      
         - Do not unlock the tunables mutex in the error path of the cpu
           frequency scheduler utils. Its not held.
      
         - Enforce proper alignement for 'struct util_est' in sched_avg to
           prevent a misalignment fault on IA64"
