Subject: [PATCH v2 01/11] powerpc/mm: fix erroneous duplicate slb_addr_limit init
Date: Thu, 25 Apr 2019 14:29:27 +0000 (UTC) [thread overview]
Message-ID: <3814377306ac3acdd404e2f23ff05dcf7e6bee26.1556202029.git.christophe.leroy@c-s.fr> (raw)
In-Reply-To: <cover.1556202028.git.christophe.leroy@c-s.fr>
Commit 67fda38f0d68 ("powerpc/mm: Move slb_addr_linit to
early_init_mmu") moved slb_addr_limit init out of setup_arch().
Commit 701101865f5d ("powerpc/mm: Reduce memory usage for mm_context_t
for radix") brought it back into setup_arch() by error.
This patch reverts that erroneous regress.
Fixes: 701101865f5d ("powerpc/mm: Reduce memory usage for mm_context_t for radix")
