Add set_irq_wake() support to intc using sysdev and suspend.

The intc controllers are put on a list at registration time
and registered as sysdev devices later on during the boot.

The sysdev class suspend callback is used to find irqs with
wakeup enabled belonging to our intc controller. Such irqs
are simply enabled so wakeup interrupts may reach the cpu.

Modify the intc code to install a disable callback. The current
solution without a disable callback results in use of the
generic default_disable() function. This function is a no-op
so suspend_device_irqs() will not disable any intc interrupts
at suspend time without this patch. Also, install enable and
shutdown callbacks while at it.

  x86, setup: guard against pre-ACPI 3 e820 code not updating %ecx

Commit 64ef8957 ("qeth: remove EDDP")
removed the qeth_core_offl.[hc] files, but ended up doing so by just
patching them to zero size, rather than removing them properly.

Actually remove the files.

  [PATCH] sysrq: include interrupt.h instead of irq.h

The current logic for dmi matching in efifb does not allow efifb to load
on all hardware that we can dmi match for.

For a real world example, boot with elilo (3.7 or 3.8 vanilla) and on a
Apple (MacBook) and EFI framebuffer driver will not load (you will have no
video).  This specific hardware is efi v1.10, so we have UGA and not GOP.
Without special bootloader magic (i.e.  extra elilo patches for UGA
graphics detection) no screen info will be passed to the kernel and as a
result efifb will not load.

This patch allows the dmi match to happen by moving it to earlier in
efifb_init, and sets the video type (in set_system) so that efifb can load
when we have a valid dmi match and already know the specifics of the
hardware.

Without this patch the efifb driver will fail to load in the event screen
info is not found and passed in by the bootloader, being that we will
never get to look for a dmi match.  A primary reason for matching with dmi
is because not all bootloaders detect the video info properly.  The
solution is that in the event of a dmi match, we should set
screen_info.orig_video_isVGA.  Most bootloaders fail to set screen info on
Apple hardware, and this is a big problem for people who use Apple
hardware.

Tested on a MacBook SantaRosa with elilo-3.8 (vanilla) and resolves the
issue, the dmi match now works, EFI framebuffer now loads and video works.

A tridentfb driver has all the functionality of the cyblafb driver without
the bugs of the latter.

Changes to the tridentfb driver:

- FBINFO_READS_FAST added to the tridentfb.  The cyblafb used a blitter
  for scrolling which is faster than color expansion on Cyberblade
  chipsets.  The blitter is slower on a discrete Blade3D core.  Use the
  blitter for scrolling in the tridentfb only for integrated Blade3D
  cores.  Now, scrolling speed is about equal for the tridentfb and the
  cyblafb.

- a copyright notice addition is done on request of Jani Monoses (the
  first author of the tridentfb).
