      Disable the __builtin_return_address() warning globally after all · ef6000b4
      Linus Torvalds authored
      This affectively reverts commit 377ccbb4 ("Makefile: Mute warning
      for __builtin_return_address(>0) for tracing only") because it turns out
      that it really isn't tracing only - it's all over the tree.
      
      We already also had the warning disabled separately for mm/usercopy.c
      (which this commit also removes), and it turns out that we will also
      want to disable it for get_lock_parent_ip(), that is used for at least
      TRACE_IRQFLAGS.  Which (when enabled) ends up being all over the tree.
      
      Steven Rostedt had a patch that tried to limit it to just the config
      options that actually triggered this, but quite frankly, the extra
      complexity and abstraction just isn't worth it.  We have never actually
      had a case where the warning is actually useful, so let's just disable
      it globally and not worry about it.

       "Some final updates and fixes for this merge window for the parisc
        architecture. Changes include:
      
         - Fix boot problems with new memblock allocator on rp3410 machine
      
         - Increase initial kernel mapping size for 32- and 64-bit kernels,
           this allows to boot bigger kernels which have many modules built-in
      
         - Fix kernel layout regarding __gp and move exception table into RO
           section
      
         - Show trap names in crashes, use extable.h header instead of
           module.h"
