[PATCH] futex: Fix additional regressions

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

Naresh reported another architecture that was broken by the same typo
that I already fixed for three architectures: mips also refers to the
futex_atomic_op_inuser_local() function by the wrong name and runs into
a missing closing '}' as well.

Going through the source tree I found that I also had the same typo in the
documentation as well as the xtensa code, both of which ended up escaping
the regression testing so far. In the case of xtensa, it appears that
the broken code path is only used when building for platforms that are
not supported by the default gcc configuration, so they are impossible
to test for with my setup.

After going through these more carefully and fixing up the typos, I
build-tested all architectures again to ensure I'm not introducing a
new regression or missing one more obvious issue with my series.

Fixes: 4e0d84634445 ("futex: Fix sparc32/m68k/nds32 build regression")
Fixes: 3f2bedabb62c ("futex: Ensure futex_atomic_cmpxchg_inatomic() is present")
