Subject: [PATCH 5/5] mm, hmm: mark hmm_devmem_{add, add_resource} EXPORT_SYMBOL_GPL
Date: Mon, 21 May 2018 15:35:40 -0700	[thread overview]
Message-ID: <152694214044.5484.1081005408496303826.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <152694211402.5484.2277538346144115181.stgit@dwillia2-desk3.amr.corp.intel.com>

The routines hmm_devmem_add(), and hmm_devmem_add_resource() are small
wrappers around devm_memremap_pages(). The devm_memremap_pages()
interface is a subset of the hmm functionality which has more and deeper
ties into the kernel memory management implementation. It was an
oversight that these symbols were not marked EXPORT_SYMBOL_GPL from the
outset due to how they originally copied (and now reuse)
devm_memremap_pages().
