      Merge tag 'efi-urgent' into x86/urgent · 697dfd88

       * The EFI variable anti-bricking algorithm merged in -rc8 broke booting
         on some Apple machines because they implement EFI spec 1.10, which
         doesn't provide a QueryVariableInfo() runtime function and the logic
         used to check for the existence of that function was insufficient.
         Fix from Josh Boyer.
      
       * The anti-bricking algorithm also introduced a compiler warning on
         32-bit. Fix from Borislav Petkov.

      parisc: use spin_lock_irqsave/spin_unlock_irqrestore for PTE updates · bda079d3
      John David Anglin authored
      
      
      User applications running on SMP kernels have long suffered from instability
      and random segmentation faults.  This patch improves the situation although
      there is more work to be done.
      
      One of the problems is the various routines in pgtable.h that update page table
      entries use different locking mechanisms, or no lock at all (set_pte_at).  This
      change modifies the routines to all use the same lock pa_dbit_lock.  This lock
      is used for dirty bit updates in the interruption code. The patch also purges
      the TLB entries associated with the PTE to ensure that inconsistent values are
      not used after the page table entry is updated.  The UP and SMP code are now
      identical.
      
      The change also includes a minor update to the purge_tlb_entries function in
      cache.c to improve its efficiency.

      parisc: disable -mlong-calls compiler option for kernel modules · cf71130d
      Helge Deller authored
      CONFIG_MLONGCALLS was introduced in commit
      ec758f98
      
       to overcome linker issues when linking
      huge linux kernels, e.g. with many modules linked in.
      
      But in the kernel module loader there is no support yet for the new relocation
      types, which is why modules built with -mlong-calls can't be loaded.
      Furthermore, for modules long calls are not really necessary, since we already
      use stub sections which resolve long distance calls.
      
      So, let's just disable this compiler option when compiling kernel modules.

      parisc: uaccess: fix compiler warnings caused by __put_user casting · 0f28b628
      Will Deacon authored
      
      
      When targetting 32-bit processors, __put_user emits a pair of stw
      instructions for the 8-byte case. If the type of __val is a pointer, the
      marshalling code casts it to the wider integer type of u64, resulting
      in the following compiler warnings:
      
        kernel/signal.c: In function 'copy_siginfo_to_user':
        kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
        kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
        [...]
      
      This patch fixes the warnings by removing the marshalling code and using
      the correct output modifiers in the __put_{user,kernel}_asm64 macros
      so that GCC will allocate the right registers without the need to
      extract the two words explicitly.

      parisc: Change kunmap macro to static inline function · 87be2f88
      John David Anglin authored
      
      
      Change kunmap macro to static inline function to fix build error
      compiling drivers/base/dma-buf.c.
      
      Without the change, the following error can occur:
      
         CC      drivers/base/dma-buf.o
      drivers/base/dma-buf.c: In function 'dma_buf_kunmap':
      drivers/base/dma-buf.c:427:46:
      error: macro "kunmap" passed 3 arguments, but takes just 1
      
      I believe parisc is the only arch to implement kunmap using a macro.

      parisc: Provide __ucmpdi2 to resolve undefined references in 32 bit builds. · ca0ad83d
      John David Anglin authored
      
      
      The Debian experimental linux source package (3.8.5-1) build fails
      with the following errors:
      ...
      MODPOST 2016 modules
      ERROR: "__ucmpdi2" [fs/btrfs/btrfs.ko] undefined!
      ERROR: "__ucmpdi2" [drivers/md/dm-verity.ko] undefined!
      
      The attached patch resolves this problem.  It is based on the s390
      implementation of ucmpdi2.c.
