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. 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") Reported-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Link: http://lkml.kernel.org/r/20200627075649.2455097-1-hch@lst.de Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
