powerpc/iseries: remove the old viocons driver

2008-08-08T01:07:10+00:00

This driver was declared obsolete over 2 years ago, the alternative console driver for legacy iSeries (hvc_iseries) was made the default over 1 year ago and this driver has been build broken for over 3 months, so remove it. Signed-off-by: Stephen Rothwell Signed-off-by: Linus Torvalds

iSeries: Fix up viotty_ioctl BKL locking fallout

2008-08-07T00:36:23+00:00

The bogus code to call into the n_tty layer got removed in commit 8bc5fb6abb670fa9079cd1994f016a39f99698fe ("Remove bogons from the iSeries console"), but it left a now uninitialized "return ret;" around. Not that this code has ever even compiled since the BKL pushdown, since not only is "ret" no longer initialized, it was never actually declared even originally. Replace it with a "return -ENOIOCTLCMD" Pointed-out-by: Paul Mackerras Acked-by: Alan Cox Signed-off-by: Linus Torvalds

Remove bogons from the iSeries console

2008-08-06T17:36:53+00:00

The iSeries driver calls into the n_tty ldisc code directly for some bizarre reason. I previously tagged this with a query but this actually does need fixing as n_tty methods when you have a different ldisc set are not a good thing to call. In n_tty mode this change should have no effect, the core tty layer has always called the ldisc ioctl method *anyway* and will call the one for the right ldisc.

viocons: BKL locking

2008-04-30T15:29:40+00:00

For some weird reason I can't ascertain (translation "I think its broken") the viocons driver calls directly into the n_tty ldisc code even if another ldisc is in use. It'll probably break if you do that but I'm just fixing the locking and adding a comment that its horked.

[PATCH] debug: add sysrq_always_enabled boot option

2006-12-13T17:05:50+00:00

Most distributions enable sysrq support but set it to 0 by default. Add a sysrq_always_enabled boot option to always-enable sysrq keys. Useful for debugging - without having to modify the disribution's config files (which might not be possible if the kernel is on a live CD, etc.). Also, while at it, clean up the sysrq interfaces.

[PATCH] const struct tty_operations

2006-10-02T14:57:14+00:00

As part of an SMP cleanliness pass over UML, I consted a bunch of structures in order to not have to document their locking. One of these structures was a struct tty_operations. In order to const it in UML without introducing compiler complaints, the declaration of tty_set_operations needs to be changed, and then all of its callers need to be fixed. This patch declares all struct tty_operations in the tree as const. In all cases, they are static and used only as input to tty_set_operations. As an extra check, I ran an i386 allyesconfig build which produced no extra warnings. 53 drivers are affected. I checked the history of a bunch of them, and in most cases, there have been only a handful of maintenance changes in the last six months. serial_core.c was the busiest one that I looked at.
