[akpm]

The patch titled
     Subject: mm: faster kmalloc_array(), kcalloc()
has been removed from the -mm tree.  Its filename was
     mm-faster-kmalloc_array-kcalloc.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Alexey Dobriyan <adobriyan@gmail.com>
Subject: mm: faster kmalloc_array(), kcalloc()

When both arguments to kmalloc_array() or kcalloc() are known at compile
time then their product is known at compile time but search for kmalloc
cache happens at runtime not at compile time.
