Subject: [PATCH 2/4] arm64: support huge vmap vmalloc
Date: Mon, 10 Jun 2019 14:38:36 +1000	[thread overview]
Message-ID: <20190610043838.27916-2-npiggin@gmail.com> (raw)
In-Reply-To: <20190610043838.27916-1-npiggin@gmail.com>

Applying huge vmap to vmalloc requires vmalloc_to_page to walk huge
pages. Define pud_large and pmd_large to support this.
