      MN10300: Fix flush_icache_range() · 57cf4f78
      David Howells authored
      
      
      flush_icache_range() is given virtual addresses to describe the region.  It
      deals with these by attempting to translate them through the current set of
      page tables.
      
      This is fine for userspace memory and vmalloc()'d areas as they are governed by
      page tables.  However, since the regions above 0x80000000 aren't translated
      through the page tables by the MMU, the kernel doesn't bother to set up page
      tables for them (see paging_init()).
      
      This means flush_icache_range() as it stands cannot be used to flush regions of
      the VM area between 0x80000000 and 0x9fffffff where the kernel resides if the
      data cache is operating in WriteBack mode.
      
      To fix this, make flush_icache_range() first check for addresses in the upper
      half of VM space and deal with them appropriately, before dealing with any
      range in the page table mapped area.
      
      Ordinarily, this is not a problem, but it has the capacity to make kprobes and
      kgdb malfunction.  It should not affect gdbstub, signal frame setup or module
      loading as gdb has its own flush functions, and the others take place in the
      page table mapped area only.

      reiserfs: fix unwanted reiserfs lock recursion · 9d8117e7
      Frederic Weisbecker authored
      
      
      Prevent from recursively locking the reiserfs lock in reiserfs_unpack()
      because we may call journal_begin() that requires the lock to be taken
      only once, otherwise it won't be able to release the lock while taking
      other mutexes, ending up in inverted dependencies between the journal
      mutex and the reiserfs lock for example.

      reiserfs: fix dependency inversion between inode and reiserfs mutexes · 3f259d09

      the inode mutex in reiserfs_unpack() without using the safe locking API,

      MAINTAINERS: update matroxfb & ncpfs status · 52653199
      Petr Vandrovec authored
      
      
      I moved couple years ago, so let's update my email and snail mail.
      
      And I do not have any access to Matrox hardware anymore, and I'm quite
      unresponsive to matroxfb bug reports (sorry Alan), so saying that I'm
      maintainer is a bit far fetched.
      
      For ncpfs I do not use ncpfs in my daily life either, but at least I can
      test that one, so I can stay listed here for odd fixes.

      proc: make /proc/pid/limits world readable · 3036e7b4
      Jiri Olsa authored
      
      
      Having the limits file world readable will ease the task of system
      management on systems where root privileges might be restricted.
      
      Having admin restricted with root priviledges, he/she could not check
      other users process' limits.
      
      Also it'd align with most of the /proc stat files.

      lib/list_sort: do not pass bad pointers to cmp callback · f015ac3e
      Don Mullis authored
      
      
      If the original list is a POT in length, the first callback from line 73
      will pass a==b both pointing to the original list_head.  This is dangerous
      because the 'list_sort()' user can use 'container_of()' and accesses the
      "containing" object, which does not necessary exist for the list head.  So
      the user can access RAM which does not belong to him.  If this is a write
      access, we can end up with memory corruption.
