rtnl_setlink doesn't allow to change subsets of the flags, just to override
the set entirely by a new one. This means that for simply setting a device
up or down userspace first needs to query the current flags, change it and
send the changed flags back, which is racy and needlessly complicated.
Mask the flags using ifi_change since this is what it is intended for.
For backwards compatibility treat ifi_change == 0 as ~0 (even though it
seems quite unlikely that anyone has been using this so far).

Prevent legacy drivers from issuing uevents for device creation/removal,

Unwinding a running task has proven problematic.
In one instance, the running task was attempting to unwind itself and
received an interrupt between when get_wchan allocated local variables on

in unw_init_frame_info to place this tasks task_struct pointer over the
switch stack's ar_bspstore entry.

Sam's recent change in 7664709b44
broke things for us because we ended up with *(.text.*) before
*(.text), whereas previously *(.text) was first. This was
important because the start of the text section contains the
kernel entry point.
In fact, we don't need that *(.text.*) thing anymore and it
incorrectly matched .text.init.refok, thus putting it before
.text. .. ouch !

the only other call to netif_poll_enable is in e1000_up() which is only
