[Andrew Morton]

The quilt patch titled
     Subject: lib/test_vmalloc.c: use late_initcall() if built-in for init ordering
has been removed from the -mm tree.  Its filename was
     lib-test_vmallocc-use-late_initcall-if-built-in-for-init-ordering.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: lib/test_vmalloc.c: use late_initcall() if built-in for init ordering

When the vmalloc test code is compiled as a built-in, use late_initcall()
instead of module_init() to defer a vmalloc test execution until most
subsystems are up and running.

It avoids interfering with components that may not yet be initialized at
module_init() time.  For example, there was a recent report of memory
profiling infrastructure not being ready early enough leading to kernel
crash.

By using late_initcall() in the built-in case, we ensure the tests are run
at a safer point during a boot sequence.
