commit ca47480921587ae30417dd234a9f79af188e3666 upstream.
Return 0 if the operation was successful, not the userspace memory
value. Check that userspace value equals passed oldval, not itself.
Don't update *uval if the value wasn't read from userspace memory.
This fixes process hang due to infinite loop in futex_lock_pi.
It also fixes a bunch of glibc tests nptl/tst-mutexpi*.

Use Kbuild infrastructure to handle the asm-generic headers
and remove the wrapper headers that call them.
This only affects headers that do nothing but include the generic
equivalent. It does not touch any header that does a little more.

Move all header files for xtensa to arch/xtensa/include and platform and
variant header files to the appropriate arch/xtensa/platforms/ and
arch/xtensa/variants/ directories.
Moving the files gets also rid of all uses of symlinks in the Makefile.
This has been completed already for the majority of the architectures
and xtensa is one out of six missing.
