This fixes a regression introduced when we switched to using the core
pci_set_power_state(). The chip seems to need the state to be written
over and over again until it sticks, so we do that.
Note that the code is a bit blunt, without timeout, etc... but that's
pretty much because I put back in there the code exactly as it used to
be before the regression. I still add a call to pci_set_power_state()
at the end so that ACPI gets called appropriately on x86.

This patch adds suspend/resume support to the LCDC
driver for SuperH Mobile - sh_mobile_lcdcfb.
We simply stop hardware on suspend and start it again
on resume. For RGB panels this is trivial, but for SYS
panels in deferred io mode this becomes a bit more
difficult - we need to wait for a frame end interrupt
to make sure the clocks are balanced before stopping
the actual hardware.

hvc_console: Remove tty->low_latency on pseries backends
powerpc: fix linkstation and storcenter compilation breakage
powerpc/4xx: Enable SERIAL_OF support by default for Virtex platforms
radeonfb and aty128fb have a special hook called by the PowerMac platform
code very very early on resume from sleep to bring the screen back. This
is useful for debugging wakup problems, but unfortunately, this also became
a source of problems of its own.
The hook is called extremely early, with interrupts still off, and the code
path involved with that code nowadays rely on things like taking mutexes,
GFP_KERNEL allocations, etc...
In addition, the driver now relies on the PCI core to restore the standard
config space before calling resume which doesn't happen with this early
code path.
I'm keeping the code in but commented out along with a fixup call to
pci_restore_state(). The reason is that I still want to make it easy to
re-enable temporarily to track wake up problems, and it's possible that
I can revive it at some stage if we make sleeping things save to call
in early resume using a system state.
In the meantime, this should fix several reported regressions.

Prevent the kernel from being crashed by a divide-by-zero operation when
supplied an incorrectly filled 'struct fb_var_screeninfo' from userland.
Previously i810_main.c:1005 (i810_check_params) was using the global
'yres' symbol previously defined at i810_main.c:145 as a module parameter
value holder (i810_main.c:2174). If i810fb is compiled-in or if this
param doesn't get a default value, this direct usage leads to a
divide-by-zero at i810_main.c:1005 (i810_check_params). The patch simply
replace the 'yres' global, perhaps undefined symbol usage by a given
parameter structure lookup.
This problem occurs with directfb, mplayer -vo fbdev, SDL library.

For historical reason, this driver used its own saving/restoring
of the PCI config space, and used the state of it on resume as
an indication as to whether it needed to re-POST the chip or not.
This methods breaks with the later core changes since the core will
have restored things for us.
This patch fixes it by removing that custom code, using standard
core methods to save/restore state, and testing for the need to
re-POST by comparing the content of a few key PLL registers.

Migration helper.
The i915 driver recently added a 'depends on FB' rule to its
Kconfig entry - which silently turns off DRM_I915 if someone
has a working config but no CONFIG_FB selected, and upgrades
to the latest upstream kernel.
Norbert Preining reported this problem:
Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12599
Subject : dri /dev node disappeared with 2.6.29-rc1
So change it to "select FB", which auto-selects framebuffer
support. This way the driver keeps working, regardless of
whether FB was enabled before or not.
Kconfig select's of interactive options can be problematic to
dependencies and can cause build breakages - but in this case
it's safe because it's a leaf entry with no dependencies of its
own.
( There is some minor circular dependency fallout as FB_I810
and FB_INTEL also used 'depends on FB' constructs - update
those to "select FB" too. )

Currently, netlink_broadcast() reports errors to the caller if no
messages at all were delivered:
1) If, at least, one message has been delivered correctly, returns 0.
2) Otherwise, if no messages at all were delivered due to skb_clone()
failure, return -ENOBUFS.
3) Otherwise, if there are no listeners, return -ESRCH.
With this patch, the caller knows if the delivery of any of the
messages to the listeners have failed:
1) If it fails to deliver any message (for whatever reason), return
-ENOBUFS.
2) Otherwise, if all messages were delivered OK, returns 0.
3) Otherwise, if no listeners, return -ESRCH.
In the current ctnetlink code and in Netfilter in general, we can add
reliable logging and connection tracking event delivery by dropping the
packets whose events were not successfully delivered over Netlink. Of
course, this option would be settable via /proc as this approach reduces
performance (in terms of filtered connections per seconds by a stateful
firewall) but providing reliable logging and event delivery (for
conntrackd) in return.
This patch also changes some clients of netlink_broadcast() that
may report ENOBUFS errors via printk. This error handling is not
of any help. Instead, the userspace daemons that are listening to
those netlink messages should resync themselves with the kernel-side
if they hit ENOBUFS.
BTW, netlink_broadcast() clients include those that call
cn_netlink_send(), nlmsg_multicast() and genlmsg_multicast() since they
internally call netlink_broadcast() and return its error value.

Since the complete re-write in 2.6.10, some PowerMacs (At least PowerMac 5500

be written to the chip. This patch uses a value calculated by aty_init_pll_ct

The code to draw penguin logos always uses some properties of the main logo.
This is incorrect if additional logos (CONFIG_FB_LOGO_EXTRA=y) have different
types than the main logo, which causes corrupted logo images.
http://bugzilla.kernel.org/show_bug.cgi?id=12181
Hence skip additional logos that are not compatible with the main logo.
Technically, it's possible to draw multiple logos of different types on
truecolor displays, but this would complicate the (already quite
complicated) logo drawing code even more.
This patch fixes a problem with Debian's linux-image-2.6.26-1-powerpc64

When I viewed drivers/video/modedb.c, I noticed a very old typo already
contained in 2.6.0.
This typo remained unheeded at least 5 years. Clear evidence of its
importance. ;)

Use the newly introduced pci_ioremap_bar() function in drivers/video.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.

The function viafb_cursor() uses 2 stack-variables of CURSOR_SIZE bits;
CURSOR_SIZE is defined as (8 * 1024). Using up twice 1k on stack is too
much for 4k-stack (though it works with 8k-stacks). Make those two
variables kzalloc'ed to preserve stack space.
Also merge the whole lot of local struct's in viafb_ioctl into a union so
the stack usage gets minimized here as well. (struct's are only accessed
in their indicidual IOCTL case) This second part is only compile-tested as
I know of no userspace app using the IOCTLs.
