Subject: [patch 2/3] uml: fix link error from prefixing of i386 syscalls with ptregs_

From: Miklos Szeredi <mszeredi@...e.cz>

Fix the following link error:

arch/um/sys-i386/built-in.o: In function `sys_call_table':
(.rodata+0x11c): undefined reference to `ptregs_fork'
arch/um/sys-i386/built-in.o: In function `sys_call_table':
(.rodata+0x140): undefined reference to `ptregs_execve'
arch/um/sys-i386/built-in.o: In function `sys_call_table':
(.rodata+0x2cc): undefined reference to `ptregs_iopl'

arch/um/sys-i386/built-in.o: In function `sys_call_table':
(.rodata+0x40c): undefined reference to `ptregs_vfork'

This was introduced by commit 253f29a4, "x86: pass in pt_regs pointer
for syscalls that need it"
