Bug#625752: linux-latest-2.6: Add sys_accept4 to arm

[Johannes Schauer <j.schauer@email.de>]

Package: linux-latest-2.6
Version: 2.6.32+27~bpo50+1
Severity: normal

the accept4 syscall is available since 2.6.28 - at least
for x86 architecture.
Support for accept4 on arm was added for 2.6.36 and the
patch is very simple:

I discovered that when updating udev from 167 to 168 (on
a 2.6.32 kernel). Udev from 168 onward requires accept4.

After applying the patch accept4 worked and so did udev.

Since accept4 is supposed to be in the kernel since
2.6.28 it should at least be put into the .32 stable
version for arm.
