This reverts commit eec9fe7d1ab4a0dfac4cb43047a7657fffd0002f.
Ari writes as the reason this should be reverted:
The problems with this patch include:
1. There's at least one subtlety I overlooked - switching
between X servers (i.e. from one X VT to another) still requires
the cooperation of both X servers. I was assuming that KMS
eliminated this.
2. It hasn't been tested at all (no X server patch exists which
uses the new mode).As he was the original author of the patch, I'll revert it.

This new VT mode (VT_PROCESS_AUTO) does everything that VT_PROCESS does
except that it doesn't wait for a VT_RELDISP ioctl before switching
away from a VT with that mode.If the X server eventually uses this new mode, debugging and crash
recovery should become easier. This is because even when currently in
the VT of a frozen X server it would still be possible to switch out
by doing SysRq-r and then CTRL-, sshing in and
doing chvt , or any other method of VT switching.
The general concensus on #xorg-devel seems to be that it should be
safe to use this with X now that we have KMS.This also moves the VT_ACKACQ define to a more appropriate place,
for clarity's sake.Signed-off-by: Ari Entlich

Fix following warning in linux-next by guarding the function definition
(both the "extern" and the inline) with #ifdef __KERNEL__.usr/include/linux/vt.h:89: userspace cannot call function or variable defined in
the kernelIntroduced by commit 5ada918b82399eef3afd6a71e3637697d6bd719f ("vt:
introduce and use vt_kmsg_redirect() function").Signed-off-by: Bernhard Walle

The kernel offers with TIOCL_GETKMSGREDIRECT ioctl() the possibility to
redirect the kernel messages to a specific console.However, since it's not possible to switch to the kernel message console
after a panic(), it would be nice if the kernel would print the panic
message on the current console.This patch series adds a new interface to access the global kmsg_redirect
variable by a function to be able to use it in code where
CONFIG_VT_CONSOLE is not set (kernel/panic.c).This patch:
Instead of using and exporting a global value kmsg_redirect, introduce a
function vt_kmsg_redirect() that both can set and return the console where
messages are printed.Change all users of kmsg_redirect (the VT code itself and kernel/power.c)
to the new interface.The main advantage is that vt_kmsg_redirect() can also be used when
CONFIG_VT_CONSOLE is not set.Signed-off-by: Bernhard Walle

As this struct is exposed to user space and the API was added for this
release it's a bit of a pain for the C++ world and we still have time to
fix it. Rename the fields before we end up with that pain in an actual

This is needed and requested in various forms for ConsoleKit, screenblank
handling and the like so do the job with a single interface. Also build the
interface so that unlike VT_WAITACTIVE and friends it won't miss events.FIXME: Should this be a waitactive ioctl or a new device file you can poll
and read events from. We need the code anyway to fix up the existing broken
wait for console switch logic but the ConsoleKit people would prefer the
new device to the ioctl we have hereSigned-off-by: Alan Cox

Some external modules like Speakup need to monitor console output.
This adds a VT notifier that such modules can use to get console output events:
allocation, deallocation, writes, other updates (cursor position, switch, etc.)[akpm@linux-foundation.org: fix headers_check]

When reading /dev/vcsa while a font with more than 256 characters is
loaded, one of the attribute bits records the 9th bit of the character.
But depending on the console driver (vgacon or fbcon for instance), that's
bit 3 or bit 0. And there is no way for userland to know that, thus no way
for userland to safely grab the screen content. So here is a (tested)
patch:Add a VT_GETHIFONTMASK ioctl for knowing which bit is the 9th bit for VC
text (vc_hi_font_mask field of the vc_data structure).Signed-off-by: Samuel Thibault

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.[akpm@osdl.org: fix alpha build]

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!
