      omap_mmc_probe lives in .init.text, so using platform_driver_register to · 8766d1d5
      Uwe Kleine-König authored 
      register it is wrong because binding a device after the init memory is
discarded (e.g.  via sysfs) results in an oops.

As requested by David Brownell platform_driver_probe is used instead of
moving the probe function to .devinit.text as proposed initially.  This
saves some memory, but devices registered after the driver is probed are
not bound (probably there are none) and binding via sysfs isn't possible.

      Add a new function to the flex_array API: · fef32d89
      David Rientjes authored 
      	int flex_array_shrink(struct flex_array *fa)

This function will free all unused second-level pages.  Since elements are
now poisoned if they are not allocated with __GFP_ZERO, it's possible to
identify parts that consist solely of unused elements.

flex_array_shrink() returns the number of pages freed.

      Newly initialized flex_array's and/or flex_array_part's are now poisoned · 8987e728
      David Rientjes authored 
      with a new poison value, FLEX_ARRAY_FREE.  It's value is similar to
POISON_FREE used in the various slab allocators, but is different to
distinguish between flex array's poisoned kmem and slab allocator poisoned
kmem.

This will allow us to identify flex_array_part's that only contain free
elements (and free them with an addition to the flex_array API).  This
could also be extended in the future to identify `get' uses on elements
that have not been `put'.

If __GFP_ZERO is passed for a part's gfp mask, the poisoning is avoided. 
These elements are considered to be in-use since they have been
initialized.
