Subject: [PATCH 3.2 122/131] sparc: use asm-generic version of types.h

3.2.63-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Sam Ravnborg <sam@...nborg.org>

commit cbf1ef6b3345d2cc7e62407eec6a6f72a8b1346f upstream.

In sparc headers we use the following pattern:

    #if defined(__sparc__) && defined(__arch64__)

    sparc64 specific stuff

    #else

    sparc32 specific stuff

    #endif

In types.h this pattern was not followed and here
we only checked for __sparc__ for no good reason.
It was a left-over from long time ago.

I checked other architectures - and most of them
do not have any such checks. And all the recently
merged versions uses the asm-generic version.

[bwh: Guenter backported this to 3.2:
 - Adjusted filenames, context
 - There's no duplicate export of types.h to delete]
