09aaf268eb fbdev: add fb_read/fb_write functions for framebuffers in system RAM
The functions fb_read() and fb_write in fbmem.c assume that the framebuffer
is in IO memory.  However, we have 3 drivers (hecubafb, arcfb, and vfb)
where the framebuffer is allocated from system RAM (via vmalloc). Using
__raw_read/__raw_write (fb_readl/fb_writel) for these drivers is
illegal, especially in other platforms.

Create file read and write methods for these types of drivers.  These are
named fb_sys_read() and fb_sys_write().

3f9b0880e4 fbdev: pass struct fb_info to fb_read and fb_write
It is unnecessary to pass struct file to fb_read() and fb_write() in struct
fb_ops. For consistency with the other methods, pass struct fb_info instead.

68648ed1f5 fbdev: add drawing functions for framebuffers in system RAM
The generic drawing functions (cfbimgblt, cfbcopyarea, cfbfillrect) assume
that the framebuffer is in IO memory.  However, we have 3 drivers (hecubafb,
arcfb, and vfb) where the framebuffer is allocated from system RAM (via
vmalloc). Using _raw_read/write and family for these drivers (as used in
the cfb* functions) is illegal, especially in other platforms.

Create 3 new drawing functions, based almost entirely from the original
except that the framebuffer memory is assumed to be in system RAM.
These are named as sysimgblt, syscopyarea, and sysfillrect.

70802c6037 fbdev: don't show logo if driver or fbcon are modular
It was always intended for the logo to be drawn only if both fbcon and the
driver that is mapped to it are both compiled statically.  Currently, if fbcon
is loaded prior to the driver, the logo is not shown.  Reverse the order, and
the code may attempt to draw the logo which is __initdata.  By accident, this
bug is rarely seen because this method of loading the modules is not common
and secondly, a code in fb_prepare_logo() that checks the height of the logo
(now a random value) rarely succeeds.

Fix by drawing the logo only if both fbcon and the driver are statically
compiled.

found in CRTC0's registers that panel size is 1920x1200 (Windows also agree
that 1920x1200 is primary monitor, and 1920x1080i secondary one).

When I applied attached patch then my monitor became as happy as it was
before I connected HDMI cable to secondary output.

86c6f7d08b tgafb: TURBOchannel support
This is support for the TC variations of the TGA boards (properly known as
SFB+ or Smart Frame Buffer Plus boards).  The 8-plane SFB+ board uses the
Bt459 RAMDAC (unlike its PCI TGA counterpart, which uses the Bt485), so
bits have been added to support this chip as well.

5e841b88d2 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()
handler will rearm the work queue normally.

(akpm: nuke unneeded ifdefs, forward-delcare struct dentry)
