Cannot call up_cpu_index() or any other nonstandard OS application interface. This not only breaks the portable POSIX OS interface but also would break any PROTECTED or KERNEL mode SMP implementation.
If you want to do something like this in user space, the appropriate thing to do would be to extend prctl(). That is non-posix, but is at least Linux-like and will work in all build modes.
This reverts commit 715517b1a0.

Merged in masayuki2009/nuttx.apps/loadable_app (pull request #148)
loadable app support
* apps: Introduce a build system for loadable apps for nsh.
This PR consits of following changes. (NOTE: Changes to each
application will be provided separately)
apps/nshlib/Kconfig:
Add 'option modules' to NSH_FILE_APPS so that a user can change
an application configuration to tristate (y/n/m)
apps/Make.defs:
Override COMPILE and COMPILEXX macros to compile loadable apps.
To make loadable apps, -DLOADABLE_APP is added to the flags.
Also, introduce ELFLD to link a lodable app.
Please note that the variable 'LOADABLE' must be defined in
each application Makefile if you want to make a loadable app.
apps/Application.mk:
Add .build target in case of 'LOADABLE=y' which is used to
link a final loadable application and install the app to
apps/bin.
apps/Makefile:
Add SYMTABSRC and SYMTABOBJ variables for loadable apps which
will be generated under the apps directory.
Add make_symbols target which will be called when all applications
are installed to generate symtab_app.c which is used for
nsh to inform symbol information to the NuttX kernel.

* apps/examples/hello: Apply changes to support a lodable app.
Kconfig:
Change the application state from bool to tristate
Make.defs:
Change the condition to build. By default, the application is
not selected (i.e. 'n'), so if other states (i.e. y/m) are
selected, the application will be compiled.
Makefile:
If the application is specified to 'm', the variable 'LOADABLE'
must be defined here. Also note that other variables (PRIORITY
and STACKSIZE) can only be used for built-in apps.
hello_main.c
Add LOADABLE_APP condition to main().
