...Fix up trivial conflicts, mostly just due to the TTY config option
clashing with the EXPERIMENTAL removal.

The option allows you to remove TTY and compile without errors. This
saves space on systems that won't support TTY interfaces anyway.
bloat-o-meter output is below.The bulk of this patch consists of Kconfig changes adding "depends on
TTY" to various serial devices and similar drivers that require the TTY
layer. Ideally, these dependencies would occur on a common intermediate
symbol such as SERIO, but most drivers "select SERIO" rather than
"depends on SERIO", and "select" does not respect dependencies.bloat-o-meter output comparing our previous minimal to new minimal by

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.CC: Rusty Russell

Currently, when a Guest wants to perform I/O it calls LHCALL_NOTIFY with
an address: the main Launcher process returns with this address, and figures
out what device to run.A far nicer model is to let processes bind an eventfd to an address: if we
find one, we simply signal the eventfd.Signed-off-by: Rusty Russell

Impact: remove unused/broken code
The Voyager subarch last built successfully on the v2.6.26 kernel
and has been stale since then and does not build on the v2.6.27,
v2.6.28 and v2.6.29-rc5 kernels.No actual users beyond the maintainer reported this breakage.
Patches were sent and most of the fixes were accepted but the
discussion around how to do a few remaining issues cleanly
fizzled out with no resolution and the code remained broken.In the v2.6.30 x86 tree development cycle 32-bit subarch support
has been reworked and removed - and the Voyager code, beyond the
build problems already known, needs serious and significant
changes and probably a rewrite to support it.CONFIG_X86_VOYAGER has been marked BROKEN then. The maintainer has
been notified but no patches have been sent so far to fix it.While all other subarchs have been converted to the new scheme,
voyager is still broken. We'd prefer to receive patches which
clean up the current situation in a constructive way, but even in
case of removal there is no obstacle to add that support back
after the issues have been sorted out in a mutually acceptable
fashion.So remove this inactive code for now.

It was moved to arch/x86/lguest/Kconfig, but I lost the deletion part in a

There's currently no way to turn on Lguest guest support; the planned
Kconfig virtualization reorg didn't get into 2.6.25.This was unnoticed because if you already had CONFIG_LGUEST_GUEST=y in
your config, it worked. Too bad about new users...Also, the Kconfig help was wrong now the virtio drivers are merged.

1) Group all the "guest OS" support options together, under a PARAVIRT_GUEST
menu.
2) Make those options select CONFIG_PARAVIRT, as suggested by Andi.
3) Make kconfig help titles consistent.Signed-off-by: Rusty Russell

Gabriel C reports lguest doesn't compile with CONFIG_BLOCK=n. Fix this
by introducing a config var for the block device, which depends on
LGUEST && BLOCK. Do the same for the net driver, rather then depending
