Date: Sun, 08 Sep 2013 03:52:01 +0100 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org CC: akpm@...ux-foundation.org, "David S. Miller" <davem@...emloft.net>, "Sam Ravnborg" <sam@...nborg.org> Subject: [097/121] sparc32: support atomic64_t 3.2.51-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Sam Ravnborg <sam@...nborg.org> commit aea1181b0bd0a09c54546399768f359d1e198e45 upstream. There is no-one that really require atomic64_t support on sparc32. But several drivers fails to build without proper atomic64 support. And for an allyesconfig build for sparc32 this is annoying. Include the generic atomic64_t support for sparc32. This has a text footprint cost: $size vmlinux (before atomic64_t support) text data bss dec hex filename 3578860 134260 108781 3821901 3a514d vmlinux $size vmlinux (after atomic64_t support) text data bss dec hex filename 3579892 130684 108781 3819357 3a475d vmlinux text increase (3579892 - 3578860) = 1032 bytes data decreases - but I fail to explain why! I have rebuild twice to check my numbers. Signed-off-by: Sam Ravnborg <sam@...nborg.org> Signed-off-by: David S.
