The problem with the asm-generic/termios.h thing is it only works
if your copying functions are just a copy_{to,from}_user() and you
can define that __ARCH_* macro.

In retrospect what that header should do is, outside of the
ARCH_* block, define the foo_1 interfaces plainly to foo.

Alternatively, here is a patch that gets sparc compiling and
working again in the current tree.

This whole termios thing hasn't been handled very well, and it's maybe
not what we should be doing so late in the -rc cycle.  And yes,
this is coming from the guy who added the TCP oops'er two weeks ago
:-P

[SPARC]: Fix build due to termios changes.
