+Subject: sparc32: support atomic64_t
+
+From: Sam Ravnborg <sam@ravnborg.org>
+
+commit aea1181b0bd0a09c54546399768f359d1e198e45 upstream, 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.
