[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.

[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. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
