[akpm]

The patch titled
     Subject: lib/test_vmalloc.c: extend max value of nr_threads parameter
has been removed from the -mm tree.  Its filename was
     lib-test_vmallocc-add-a-new-nr_threads-parameter-fix.patch

This patch was dropped because it was folded into lib-test_vmallocc-add-a-new-nr_threads-parameter.patch

Subject: lib/test_vmalloc.c: extend max value of nr_threads parameter

Currently a maximum value is set to 1024 workers the user can
create during the test. It might be that for some big systems
it is not enough. Since it is a test thing we can give testers
more flexibility.

Increase that number till USHRT_MAX that corresponds to 65535.
