net: wan: add missing virt_to_bus dependencies

2015-01-29T23:08:21+00:00

The cosa driver is rather outdated and does not get built on most
platforms because it requires the ISA_DMA_API symbol. However
there are some ARM platforms that have ISA_DMA_API but no virt_to_bus,
and they get this build error when enabling the ltpc driver.

drivers/net/wan/cosa.c: In function 'tx_interrupt':
drivers/net/wan/cosa.c:1768:3: error: implicit declaration of function 'virt_to_bus'
   unsigned long addr = virt_to_bus(cosa->txbuf);
   ^

The same problem exists for the Hostess SV-11 and Sealevel Systems 4021
drivers.

This adds another dependency in Kconfig to avoid that configuration.

wanrouter: completely decouple obsolete code from kernel.

2013-02-01T00:20:33+00:00

The original suggestion to delete wanrouter started earlier
with the mainline commit f0d1b3c2bcc5de8a17af5f2274f7fcde8292b5fc
("net/wanrouter: Deprecate and schedule for removal") in May 2012.

More importantly, Dan Carpenter found[1] that the driver had a
fundamental breakage introduced back in 2008, with commit
7be6065b39c3 ("netdevice wanrouter: Convert directly reference of
netdev->priv").  So we know with certainty that the code hasn't been
used by anyone willing to at least take the effort to send an e-mail
report of breakage for at least 4 years.

This commit does a decouple of the wanrouter subsystem, by going
after the Makefile/Kconfig and similar files, so that these mainline
files that we are keeping do not have the big wanrouter file/driver
deletion commit tied into their history.

Once this commit is in place, we then can remove the obsolete cyclomx
drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.

tty: Added a CONFIG_TTY option to allow removal of TTY

2013-01-19T00:15:27+00:00

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
removing TTY.  The list is filtered to not show removed entries with awk
'$3 != "-"' as the list was very long.

drivers/net/wan: remove depends on CONFIG_EXPERIMENTAL

2013-01-11T19:38:41+00:00

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.

NET: pc300, move to staging as it is broken

2012-04-13T17:57:04+00:00

It was marked as BROKEN back in 2008. It is because the tty handling
in the driver is really broken.

There was some activity in January 2012 to fix the driver, but the
patch was commented to be bogus:
  https://lkml.org/lkml/2012/1/29/160
and we have not heard back from the author since then:
  https://lkml.org/lkml/2012/3/28/412

So since nobody stepped in and rewrote the driver, it is time to move
it out of line now. And drop it some time later if nobody comes up
with patches to fix the driver in staging.

Documentation: remove references to /etc/modprobe.conf

2012-03-30T23:03:15+00:00

Usage of /etc/modprobe.conf file was deprecated by module-init-tools and
is no longer parsed by new kmod tool. References to this file are
replaced in Documentation, comments and Kconfig according to the
context.

There are also some references to the old /etc/modules.conf from 2.4
kernels that are being removed.
