Fix to fall back to find a probe point in symbols if perf fails to find
it in debuginfo.

This can happen when the target function is an alias of another
function. Such alias doesn't have an entry in debuginfo but in symbols.

David Ahern reported this problem in https://lkml.org/lkml/2014/12/29/355

I ensured the problem and deeper investigation discovers it.

All these entires have no instances (all of them are declarations)
This is why the perf probe failed to find it in debuginfo.

However, there are some malloc instances in symbols.

 -----
As you an see, malloc and __libc_malloc have same address, and actually
__libc_malloc has an entry in debuginfo. So you can set up a probe on
__libc_malloc.

To fix this problem shortly, perf probe simply falls back to find probe
point(malloc) in symbols if it is not found in debuginfo.

This reverts commit 24a0aa21.

It's causing severe userspace breakage.  Namely, all the utilities from
wireless-utils which are relying on CONFIG_WEXT (which means tools like
'iwconfig', 'iwlist', etc) are not working anymore.  There is a 'iw'
utility in newer wireless-tools, which is supposed to be a replacement
for all the "deprecated" binaries, but it's far away from being
massively adopted.

Please see [1] for example of the userspace breakage this is causing.

In addition to that, Larry Finger reports [2] that this patch is also
causing ipw2200 driver being impossible to build.

To me this clearly shows that CONFIG_WEXT is far, far away from being
"deprecated enough" to be removed.

Unfortunately, while commit 4a928436 ("audit: correctly record file
names with different path name types") fixed a problem where we were
not recording filenames, it created a new problem by attempting to use
these file names after they had been freed.  This patch resolves the
issue by creating a copy of the filename which the audit subsystem
frees after it is done with the string.

At some point it would be nice to resolve this issue with refcounts,
or something similar, instead of having to allocate/copy strings, but
that is almost surely beyond the scope of a -rcX patch so we'll defer
that for later.  On the plus side, only audit users should be impacted
by the string copying.

  mmc: core: stop trying to switch width when only one bit is supported

Pull thermal management updates from Zhang Rui:
 "First of all, the most important change is the thermal cpu cooling
  fixes.  The major fix here is to have proper sequencing between
  cpufreq layer and thermal cpu cooling registration.  A take away of
  this fix is an improvement in the thermal drivers code.  Thermal
  drivers that require cpu cooling do not need to check for cpufreq
  layer.  The requirement now is to propagate the error code, if any,
  while registering cpu cooling device.  Thanks to Viresh for
  implementing the required CPUfreq changes.

  Second, a new driver is introduced for int340x processor thermal
  device.  Given that int340x thermal is disabled by default, and this
  processor thermal device is only available on limited platforms, plus
  the driver does nothing but exposes some thermal limitation
  information for user space to use, thus I think it is safe to include
  it in this pull request after missing 3.19-rc2.

  Specifics:

   - Thermal cpu cooling fixes and cleanups.

   - introduce INT340X processor thermal reporting device driver.

   - several small fixes and cleanups for int340x thermal drivers"

Commit 2457aec6 ("mm: non-atomically mark page accessed during page
cache allocation where possible") has added a separate parameter for
specifying gfp mask for radix tree allocations.

Not only this is less than optimal from the API point of view because it
is error prone, it is also buggy currently because
grab_cache_page_write_begin is using GFP_KERNEL for radix tree and if
fgp_flags doesn't contain FGP_NOFS (mostly controlled by fs by
AOP_FLAG_NOFS flag) but the mapping_gfp_mask has __GFP_FS cleared then
the radix tree allocation wouldn't obey the restriction and might
recurse into filesystem and cause deadlocks.  This is the case for most
filesystems unfortunately because only ext4 and gfs2 are using
AOP_FLAG_NOFS.

Let's simply remove radix_gfp_mask parameter because the allocation
context is same for both page cache and for the radix tree.  Just make
sure that the radix tree gets only the sane subset of the mask (e.g.  do
not pass __GFP_WRITE).

Long term it is more preferable to convert remaining users of
AOP_FLAG_NOFS to use mapping_gfp_mask instead and simplify this
interface even further.

If the probe of an fb driver has been deferred due to missing
dependencies, and the probe is later ran when a module is loaded, the
fbdev framework will try to find a logo to use.

However, the logos are __initdata, and have already been freed. This
causes sometimes page faults, if the logo memory is not mapped,
sometimes other random crashes as the logo data is invalid, and
sometimes nothing, if the fbdev decides to reject the logo (e.g. the
random value depicting the logo's height is too big).

This patch adds a late_initcall function to mark the logos as freed. In
reality the logos are freed later, and fbdev probe may be ran between
this late_initcall and the freeing of the logos. In that case we will
miss drawing the logo, even if it would be possible.
