Subject: [PATCH v4 12/17] arm64: trans_pgd: pass NULL instead of init_mm to *_populate functions
Date: Mon, 9 Sep 2019 14:12:16 -0400 [thread overview]
Message-ID: <20190909181221.309510-13-pasha.tatashin@soleen.com> (raw)
In-Reply-To: <20190909181221.309510-1-pasha.tatashin@soleen.com>
trans_pgd_* should be independent from mm context because the tables that
are created by this code are used when there are no mm context around, as
it is between kernels. Simply replace mm_init's with NULL.
