fb: fsync() method for deferred I/O flush.
There are cases when we do not want to wait on the delay for automatically
updating the "real" framebuffer, this implements a simple ->fsync() hook
for explicitly flushing the deferred I/O work. The ->page_mkwrite()

fbdev: mm: Deferred IO support
This implements deferred IO support in fbdev. Deferred IO is a way to delay
and repurpose IO. This implementation is done using mm's page_mkwrite and
page_mkclean hooks in order to detect, delay and then rewrite IO. This
functionality is used by hecubafb.

This is useful for graphics hardware with no directly addressable/mappable
framebuffer. Implementing this will allow the "framebuffer" to be accesible
from user space via mmap().
fbdev: ignore VESA modes if framebuffer is disabled
If the option vga=<VESA graphics mode> is added to the boot parameter, it will
activate graphics mode, but without any framebuffer support, the user is left
with an unusable display.
Change the behavior such that the user is instead prompted for another mode
(ala vga=ask).
NOTE: People can always use vbetool to set a graphics mode if this is really
desired, but the number of people doing this approaches zero.

I have a problem with blanking. The soundcard uses speakers of the monitor.
Sound is muted when the screen blanks due to a bug in aty128fb.c.
Here is a fragment of linux/fb.h
/* VESA Blanking Levels */
#define VESA_NO_BLANKING 0
#define VESA_VSYNC_SUSPEND 1
#define VESA_HSYNC_SUSPEND 2
#define VESA_POWERDOWN 3

/* screen: unblanked, hsync: on, vsync: on */
FB_BLANK_UNBLANK = VESA_NO_BLANKING,
/* screen: blanked, hsync: on, vsync: on */
FB_BLANK_NORMAL = VESA_NO_BLANKING + 1,
/* screen: blanked, hsync: on, vsync: off */
FB_BLANK_VSYNC_SUSPEND = VESA_VSYNC_SUSPEND + 1,
So FB_BLANK_NORMAL is 1, FB_BLANK_VSYNC_SUSPEND is 2,
FB_BLANK_HSYNC_SUSPEND is 3, FB_BLANK_POWERDOWN is 4.
And now:
blank = FB_BLANK_NORMAL (1)
blank & FB_BLANK_HSYNC_SUSPEND (1 & 3) is true,
so normal blank caused hsync suspend and sound is muted.

x86, serial: convert legacy COM ports to platform devices
Make x86 COM ports into platform devices and don't probe for them
if we have PNP.
This prevents double discovery, where a device was found both by
the legacy probe and by 8250_pnp, e.g.,
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
This also means IRDA devices without a UART PNP ID will no longer be
claimed by the serial driver, which might require changes in IRDA
drivers and administration.
In addition to this patch, you may need to configure a setserial init
script, e.g., /etc/init.d/setserial, so it doesn't poke legacy UART
stuff back in. On Debian, "dpkg-reconfigure setserial" with the "kernel"
option does this.
To force the old legacy probe behavior even when we have PNPBIOS or
ACPI, load the new legacy_serial module (or build 8250 static) with
the "legacy_serial.force" option.

smsc-ircc2: add PNP support
Claim devices using PNP, unless the user explicitly specified device
addresses. This can be disabled with the "smsc-ircc2.nopnp" option.
This removes the need for probing legacy addresses and helps untangle IR
devices from serial8250 devices.
Sometimes the SMC device is at a legacy COM port address but does not use the
legacy COM IRQ. In this case, claiming the device using PNP rather than 8250
legacy probe means we can automatically use the correct IRQ rather than
forcing the user to use "setserial" to set the IRQ manually.
If the PNP claim doesn't work, make sure you don't have a setserial init
script, e.g., /etc/init.d/setserial, configured to poke in legacy COM port
resources for the IRDA device. That causes the serial driver to claim
resources needed by this driver.

PNP: notice whether we have PNP devices (PNPBIOS or PNPACPI)
This series converts i386 and x86_64 legacy serial ports to be platform
devices and prevents probing for them if we have PNP.
This prevents double discovery, where a device was found both by the legacy
probe and by 8250_pnp.
This also prevents the serial driver from claiming IRDA devices (unless they
have a UART PNP ID). The serial legacy probe sometimes assumed the wrong IRQ,
so the user had to use "setserial" to fix it.
Removing the need for setserial to make IRDA devices work seems good, but it
does break some things. In particular, you may need to keep setserial from
poking legacy UART stuff back in by doing something like "dpkg-reconfigure
setserial" with the "kernel" option. Otherwise, the setserial-discovered
"UART" will claim resources and prevent the IRDA driver from loading.
This patch:
If we can discover devices using PNP, we can skip some legacy probes. This
flag ("pnp_platform_devices") indicates that PNPBIOS or PNPACPI is enabled and
should tell us about builtin devices.

I agree (with Andi Kleen) this typeof is not needed and more error

probably to circumvent a circular dependency between system.h and
atomic.h on powerpc (which my patch addresses). Therefore, it makes
sense to use inline functions that will provide type checking.
