ebde441177 fbdev: fix color component field length documentation
The documentation about the meaning of the color component bitfield
lengths in pseudocolor modes is inconsistent.  Fix it, so that it
indicates the correct interpretation everywhere, i.e.  that 1 << length is
the number of palette entries.

b604838ac6 vfb: only enable if explicitly requested when compiled in
The Kconfig help for the vfb driver says:
   Do NOT enable it for normal systems! To protect the innocent, it
   has to be enabled explicitly at boot time using the kernel option
   `video=vfb:'.

This change lets the code match the description.

Support for vfb:disable is kept for backwards compatibility; vfb:off works
because it is tested at a higher level.

Note: any undefined option (e.g. vfb:enable) will also enable this driver.

The relevant code has been unchanged since before the migration to
git (2.6.12).

This patch fixes bugzilla #9310 and was the root cause behind
http://lkml.org/lkml/2008/5/31/220.

68e5e9d734 vfb: make virtual framebuffer mmapable
Changed things:

1. vmalloc()/vfree() replaced with rvmalloc()/rvfree() (taken from
   drivers/media/video/se401.c)

2. mmap method implemented (mostly taken from drivers/media/video/se401.c)

3. smem_start and smem_len fields of struct fb_fix_screeninfo initialized.
    (smem_start initialized with virtual address, don't know if it is really
   bad...)

This patch replaces <asm/uaccess.h> with <linux/uaccess.h> after the
checkpatch.pl hint.  The include of <asm/uaccess.h> is removed if the driver
does not use it.

a8f340e394 [PATCH] vt: Remove VT-specific declarations and definitions from tty.h
MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a
function of the VT layer than the TTY one.  Moving these to vt.h and vt_kern.h
allows all of the framebuffer and VT console drivers to remove their
dependency on tty.h.

No need for a file argument.  If we'd really need it it's in vma->vm_file

c465e05a03 [PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbcon
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for
drivers that do not support hardware cursors is redundant.  The soft_cursor
function is usable by all drivers because it is just a wrapper around
fb_imageblit.  And because soft_cursor is an fbcon-specific hook, the file is
moved to the console directory.

Thus, drivers that do not support hardware cursors can leave the fb_cursor
field blank.  For drivers that do, they can fill up this field with their own
version.

The end result is a smaller code size.  And if the framebuffer console is not
loaded, module/kernel size is also reduced because the soft_cursor module will
also not be loaded.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
