cda1fd5a60 microblaze: Cleanup compiled-in rootfs in BSS section 
This patch is based on patch from Steve Magnani.

There were bug for compiled-in rootfs. We have to move
moving rootfs which is in BSS section to _ebss section
which is at the end of kernel and then clear bss section
not vice-versa.

1dff89a9c7 microblaze: Fix early cmdline for CMDLINE_FORCE 
This patch fixed parsing early parameters because
current implementation does that early parse DTS
command line and then parse CMDLINE line which is compiled-in.

For case that DTS doesn't contain command line is
copied command line from kernel with is done in prom.c
that's why I can remove it from machine_early_init.

a6029d1c8c microblaze: prepare signal handling for generic unistd.h 
We need to define set_restore_sigmask() in order to
get pselect and ppoll. Also, the setup_frame function
can not be used when __NR_sigreturn is not defined.

70f4cc2935 microblaze: kill incorrect __bad_xchg definition 
The whole point of the __bad_xchg declaration in
system.h is to give a linker error when a variable
of invalid size is passed to __xchg. The out
of line definition in traps.c defeats this purpose
and does not any value, so remove it here.

353b431baf microblaze: fix __user annotations 
The microblaze signal handling code gets some __user

This adds the annotations where appropriate and
change sys_rt_sigreturn to correctly pass a user
stack down to do_sigaltstack instead of a kernel
structure.
