       "I know it's *very* late in the 3.9 release cycle, but since there
        aren't that many people testing the parisc linux kernel, a few (for

        time.
      
        What's in it?
         - add missing __ucmpdi2 symbol, which is required for btrfs on 32bit
           kernel.
         - change kunmap() macro to static inline function.  This fixes a
           debian/gcc-4.4 build error.
         - add locking when doing PTE updates.  This fixes random userspace
           crashes.
         - disable (optional) -mlong-calls compiler option for modules, else
           modules can't be loaded at runtime.
         - a smart patch by Will Deacon which fixes 64bit put_user() warnings
           on 32bit kernel."

      efivars: only check for duplicates on the registered list · f464246d
      Matt Fleming 提交于
      variable_is_present() accesses '__efivars' directly, but when called via
      gsmi_init() Michel reports observing the following crash,
      
        BUG: unable to handle kernel NULL pointer dereference at (null)
        IP: variable_is_present+0x55/0x170
        Call Trace:
          register_efivars+0x106/0x370
          gsmi_init+0x2ad/0x3da
          do_one_initcall+0x3f/0x170
      
      The reason for the crash is that '__efivars' hasn't been initialised nor
      has it been registered with register_efivars() by the time the google
      EFI SMI driver runs.  The gsmi code uses its own struct efivars, and
      therefore, a different variable list.  Fix the above crash by passing
      the registered struct efivars to variable_is_present(), so that we
      traverse the correct list.

      TTY: fix atime/mtime regression · 37b7f3c7
      Jiri Slaby 提交于
      In commit b0de59b5 ("TTY: do not update atime/mtime on read/write")
      we removed timestamps from tty inodes to fix a security issue and waited
      if something breaks.  Well, 'w', the utility to find out logged users
      and their inactivity time broke.  It shows that users are inactive since
      the time they logged in.
      
      To revert to the old behaviour while still preventing attackers to
      guess the password length, we update the timestamps in one-minute
      intervals by this patch.

      parisc: use spin_lock_irqsave/spin_unlock_irqrestore for PTE updates · bda079d3
      John David Anglin 提交于
      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 提交于
      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 提交于
      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.

      efi: Check EFI revision in setup_efi_vars · f697036b
      Josh Boyer 提交于
      We need to check the runtime sys_table for the EFI version the firmware
      specifies instead of just checking for a NULL QueryVariableInfo.  Older
      implementations of EFI don't have QueryVariableInfo but the runtime is
      a smaller structure, so the pointer to it may be pointing off into garbage.
      
      This is apparently the case with several Apple firmwares that support EFI
      1.10, and the current check causes them to no longer boot.  Fix based on
      a suggestion from Matthew Garrett.
