4bdd03e61b [SCSI] lpfc: fix problems with -Werror 
Commit d38bd3aef ("Add -Werror compilation flag") is causing build breakage
with random gcc incarnations.  These look like gcc problems, but we shouldn't
break the build because of a bad gcc.  Fix this by adding a make flag

WARNINGS_BECOME_ERRORS=1

which is the same as aic7xxx uses so ordinarily the build doesn't use -Werror

5d32c88f0b Merge branch 'akpm' (Andrew's patch-bomb) 
Merge batch of fixes from Andrew Morton:
 "The simple_open() cleanup was held back while I wanted for laggards to
  merge things.

  I still need to send a few checkpoint/restore patches.  I've been
  wobbly about merging them because I'm wobbly about the overall
  prospects for success of the project.  But after speaking with Pavel
  at the LSF conference, it sounds like they're further toward
  completion than I feared - apparently davem is at the "has stopped
  complaining" stage regarding the net changes.  So I need to go back
  and re-review those patchs and their (lengthy) discussion."

234e340582 simple_open: automatically convert to simple_open() 
Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op.  This leads to a
proliferation of the default_open() implementation across the entire
tree.

Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().

This replacement was done with the following semantic patch:

<smpl>
@ open @
identifier open_f != simple_open;
identifier i, f;
@@
-int open_f(struct inode *i, struct file *f)
-{
(
-if (i->i_private)
-f->private_data = i->i_private;
|
-f->private_data = i->i_private;
)
-return 0;
-}

@ has_open depends on open @
identifier fops;
identifier open.open_f;
@@
struct file_operations fops = {
...
-.open = open_f,
+.open = simple_open,
...
};
</smpl>
