Subject: [PATCH v2 09/19] ARC: mm: switch to asm-generic/pgalloc.h
Date: Thu, 12 Aug 2021 16:37:43 -0700	[thread overview]
Message-ID: <20210812233753.104217-10-vgupta@kernel.org> (raw)
In-Reply-To: <20210812233753.104217-1-vgupta@kernel.org>

With previous patch ARC pgalloc functions are same as generic, hence
switch to that.
