Commit aea1181b0bd0a09c54546399768f359d1e198e45 upstream [Backport to 3.0.y. Needed to compile ext4 for sparc32 since commit 503f4bdcc078e7abee273a85ce322de81b18a224]
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 <[email protected]> Signed-off-by: David S.
