The number and types of parameters is such that no ARM-specific processing is needed, so wiring up sys_accept4() just requires defining __NR_accept4 and adding a direct call in the syscall entry table. Tested with an EABI 2.6.35 kernel and Ulrich Drepper's original accept4() test program, modified to define __NR_accept4 for ARM. Using the updated unistd.h also eliminates a warning then building glibc (2.10.2 and newer) about accept4() being unimplemented.

If a video head and keyboard are hooked up, specifying "console=ttyS0" or similar to use a serial console will not work properly. The key issue is that we must register all serial console capable devices with register_console(), otherwise the command line specified device won't be found. The sun serial drivers would only register themselves as console devices if the OpenFirmware specified console device node matched. To fix this part we now unconditionally get the serial console register by setting serial_drv->cons always. Secondarily we must not add_preferred_console() using the firmware provided console setting if the user gaven an override on the kernel command line using "console=" The "primary framebuffer" matching logic was always triggering o n openfirmware device node match, make it not when a command line override was given.

This is because do_execve() passes a pointer to the filename (now const) to copy_strings_kernel(). A simpler alternative would be to cast the filename pointer in do_execve() when it's passed to copy_strings_kernel(). do_execve() may not change any of the strings it is passed as part of the argv or envp lists as they are some of them in .rodata, so marking these strings as const should be fine. Further kernel_execve() and sys_execve() need to be changed to match. This has been test built on x86_64, frv, arm and mips.
