Subject: [ 30/30] sparc32: support atomic64_t
Date: Mon, 29 Apr 2013 12:02:54 -0700 [thread overview]
Message-ID: <20130429184358.679521952@linuxfoundation.org> (raw)
In-Reply-To: <20130429184355.299556377@linuxfoundation.org>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
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.
