[PATCH] um: use KERN_CONT in stack dump

[Vegard Nossum]

Without KERN_CONT, the symbol will appear on a new line, making stack
traces completely unreadable:

    Call Trace:
     [<6008e891>] ?
    printk+0x0/0x94
     [<6001cce6>]
    show_stack+0xfe/0x15b
     [<600666ec>] ?
    dump_stack_print_info+0xe1/0xea
     [<6008e891>] ?
    printk+0x0/0x94
     [<6023e826>] ?
    bust_spinlocks+0x0/0x4f
     [<602343b8>]
    dump_stack+0x2a/0x2c
     [<6008e662>]
    panic+0x170/0x31e
     [<6008e4f2>] ?
    panic+0x0/0x31e

This makes it readable again:

    Call Trace:
     [<6008e891>] ? printk+0x0/0x94
     [<6001cce6>] show_stack+0xfe/0x15b
     [<600666ec>] ? dump_stack_print_info+0xe1/0xea
     [<6008e891>] ? printk+0x0/0x94
     [<6023e826>] ? bust_spinlocks+0x0/0x4f
     [<602343b8>] dump_stack+0x2a/0x2c
     [<6008e662>] panic+0x170/0x31e
