1.  From Petr Vandrovec <vandrove@vc.cvut.cz>.

Begin quote

        yesterday I finally found why 2.6.x has problems with taking
        over vgacon.  Problem is that take_over_console does:

  	if (IS_VISIBLE)
    	save_screen(i);
  	...
  	visual_init(i, 0);
  	...

        so code nicely saves screen contents, and calls visual_init,
        which calls fbcon's init, which in turn can issue vc_resize.  And this
        vc_resize will trigger read from vc->vc_origin.  But vc_origin still
        points to videomemory, not to the buffer where save_screen() copied
        its data.

End quote

So updating vc->vc_origin to point to screenbuf after the previous console
deinitializes allows fbcon to correctly update the screen from the screen
buffer.  This change makes the clearing of vram (using fillrect) unnecessary.

2.  If FBINFO_MISC_MODESWITCH flag is set in info, do the set_par() in
fbcon_switch() instead of piggy-backing the set_par() on fbcon_resize().  This
preserves the current var, skipping the unnecessary fb_find_mode() step.

Ugly workaround.  When switching from KD_GRAPHICS to KD_TEXT, the event is
captured at fbcon_blank() allowing fbcon to reinitialize the hardware.
However, some hardware requires the reinitialization to be done
immediately, others require it to be done later.  Others may need it to be
done immediately and later, this is the worst case.

This patch introduces a notifier chain for cpu idle.  There are two events
CPU_IDLE and CPU_NOT_IDLE that are called just before the cpu goes to sleep
and right after the cpu woke up again.  The notifier is used to simplify the
no-hz-timer-in-idle feature and the virtual cpu timers.  In addition the
virtual cpu timer functions have been moved to arch/s390/kernel/vtime.c, which
gives a nice separation between the timer functions related to real time and
the timer functions related to virtual cpu time.

This patch makes netlink_connect() return the value of err instead of 0.
It doesn't actually make any difference since the current implementation
of netlink_autobind() never fails.  But since we went to all this trouble
to check the return status of autobind, might as well return the correct
value :)

While getting hands-on with netkit (www.netkit.org), a networking
simulation environment based on UML, it struck me that ifconfig wasn't
capable of calculating the proper broadcast address for a subnetted
interface. Some browsing through newsgroups and on the Debian package
site (nettools), showed that this leads to misconfigured interfaces and
a couple of bugreports on ifconfig.

Digging a bit deeper revealed that it actually is an issue with
SIOIFNETMASK. Once you bring up an interface with SIOIFADDR, a classfull
netmask and broadcast address is set (if applicable for the type of
interface), in order to get a properly configured interface. But if you
subnet the network using SIOIFNETMASK no proper broadcast address is
set. So you always have to calculate it yourself, obviously leading to
configuration errors.

This patch takes care of this. First of all it doesn't change
existing functionality, eg. a command like 'ifconfig eth0 192.168.1.1
netmask 255.255.255.240 broadcast 192.168.1.0' still works. But if you
omit the broadcast address, a proper 'all ones' broadcast address for the
subnet is set. 'ifconfig eth0 192.168.1.1 netmask 255.255.255.240' gives
you 'eth0 inet addr:192.168.1.1 Bcast:192.168.1.15 Mask:255.255.255.240'
and this should solve some real life problems.
