[merged] mm-switch-the-test_vmalloc-module-to-use-__vmalloc_node.patch removed from -mm tree

[akpm]

The patch titled
     Subject: mm: switch the test_vmalloc module to use __vmalloc_node
has been removed from the -mm tree.  Its filename was
     mm-switch-the-test_vmalloc-module-to-use-__vmalloc_node.patch

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

------------------------------------------------------
From: Christoph Hellwig <hch@lst.de>
Subject: mm: switch the test_vmalloc module to use __vmalloc_node

No need to export the very low-level __vmalloc_node_range when the test
module can use a slightly higher level variant.

[akpm@linux-foundation.org: add missing `node' arg]
[akpm@linux-foundation.org: fix riscv nommu build]
