Subject: [PATCH V2] Skip unnecessary pte makeup when clearing it
Date: Mon, 30 Jan 2012 09:43:11 +0800 [thread overview]
Message-ID: <1327887792-3103-1-git-send-email-bill4carson@gmail.com> (raw)
If we are only about to clear a hardware pte entry, then pte makeup code is
unnecessary for cpu_v7_set_pte_ext and armv6_set_pte_ext, so just skip it.

Changes for V2:
- Use "1f" instead of "set_pte" as label
- Build/bootup test with thumb mode
- checkpatch script shows:
total: 0 errors, 0 warnings, 44 lines checked
./0001-Skip-unnecessary-pte-makeup-when-clearing-it.patch has no obvious style problems and is ready for submission.
