c760fc1997 [ARM] nommu: fixups for the exception vectors 
The high page vector (0xFFFF0000) does not supported in nommu mode.
This patch allows the vectors to be 0x00000000 or the begining of DRAM
in nommu mode.

fcca538b83 [ARM] 3270/1: ARM EABI: fix sigreturn and rt_sigreturn 
Patch from Nicolas Pitre

The signal return path consists of user code provided by the kernel.
Since a syscall is used, it has to be updated to work with EABI.

Noticed by Daniel Jacobowitz.

e00d349e77 [PATCH] ARM: Move signal return code into vector page 
Move the signal return code into the vector page instead of placing
it on the user mode stack, which will allow us to avoid flushing
the instruction cache on signals, as well as eventually allowing
non-exec stack.
