[PATCH 2.6.9-rc1-mm4 3/6] [m32r] Update to fix compile errors
This patch updates code to fix compile errors, and so on.

* arch/m32r/kernel/Makefile:
Change linker script's name from vmlinux.lds.s to vmlinux.lds.

* arch/m32r/kernel/process.c (sys_clone):
Fix the first parameter of do_fork() call.

* arch/m32r/kernel/signal.c:
(handle_signal): Add a new second argument, struct k_sigaction *ka.
(do_signal): Change get_signal_to_deliver() interface.

* include/asm-m32r/hardirq.h:
Some declarations are moved to linux/hardirq.h.

* include/asm-m32r/page.h:
Add devmem_is_allowed() macro.
