[patch 4/5] vmalloc: fix the owner argument for the new __vmalloc_node_range callers

[Andrew Morton <akpm@linux-foundation.org>]

From: Christoph Hellwig <hch@lst.de>
Subject: vmalloc: fix the owner argument for the new __vmalloc_node_range callers

Fix the recently added new __vmalloc_node_range callers to pass the
correct values as the owner for display in /proc/vmallocinfo.

Link: http://lkml.kernel.org/r/20200627075649.2455097-1-hch@lst.de
Fixes: 800e26b81311 ("x86/hyperv: allocate the hypercall page with only read and execute bits")
Fixes: 10d5e97c1bf8 ("arm64: use PAGE_KERNEL_ROX directly in alloc_insn_page")
Fixes: 7a0e27b2a0ce ("mm: remove vmalloc_exec")
