Subject: [PATCH v1 03/19] powerpc/40x: Remove stale PTE_ATOMIC_UPDATES macro
Date: Mon, 11 Sep 2023 21:03:09 +0200 [thread overview]
Message-ID: <3decc02a589d43172f4b7b59e88f3f5ec9c4bcda.1694443576.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1694443576.git.christophe.leroy@csgroup.eu>
40x TLB handlers were reworked by commit 2c74e2586bb9 ("powerpc/40x:
Rework 40x PTE access and TLB miss") to not require PTE_ATOMIC_UPDATES
anymore.
Then commit 4e1df545e2fa ("powerpc/pgtable: Drop PTE_ATOMIC_UPDATES")
removed all code related to PTE_ATOMIC_UPDATES.
Remove left over PTE_ATOMIC_UPDATES macro.
Fixes: 2c74e2586bb9 ("powerpc/40x: Rework 40x PTE access and TLB miss")
