Subject: [PATCH] ARM: mm: iomap: use is_vmalloc_addr
Date: Thu, 13 Jul 2017 23:30:52 -0500	[thread overview]
Message-ID: <20170714043052.GA27345@embeddedgus> (raw)

Instead of manually checking the bounds of VMALLOC_START and VMALLOC_END,
use is_vmalloc_addr. Such function was specifically designed for that
purpose.
