I write it now a little bit lightweight - or maybe for recuse disks - okay?

Hi Linus, do you think it is possible to get this patch in the offical kernel?

I had it tested now very well, and it should have no side effects with the new
macro expantion. All arguments of the printk and panic macro will be evaulated.

Sorry, here is the correct version of the patch, without line wraps:

+Disable kernel messages
+CONFIG_NOPRINTK
+  This option allows you to disable all kernel messages by overriding
+  the printk function a dummy macro.
+  On small embedded systems, this save a lot of rom and ram space. On
+  server or desktop systems you want human readable outputs, so it is
+  normally the best choice to say N to this option.

 Support for console on virtual terminal

Hi folks,

this patch make the linux irda smc-ircc driver working the newer LPC47xxx smc chips, 
with are mostly used in notebook computers.

I added also support for all smc super i/o chips, which i had found a reference manual
on the smc webpage:

LPC47B37X
LPC47M10X
LPC47M120
LPC47M13X
LPC47M14X
LPC47N252
LPC47S42X

It was tested currently on my INSPIRON 8000, so feedbacks are welcome

I hope this patch will go in to the 2.4 tree...

Greetings

Hi folks,

sorry about the previous patch, it was my test code, which will not work....

This patch make the linux irda smc-ircc driver working with the newer LPC47xxx smc chips, 
mostly found notebook computers.

I added also support for all smc super i/o chips, which i have found a reference manual
on the smc webpage:

FDC37C44
FDC37C665GT
FDC37C669
FDC37C669
FDC37C78
FDC37N769
FDC37N869
FDC37B72X
FDC37B77X
FDC37B78X
FDC37B80X
FDC37C67X
FDC37C93X
FDC37C93XAPM
FDC37C93XFR
FDC37M707
FDC37M81X
FDC37N958FR
FDC37N972
LPC47N227
LPC47N267
LPC47B27X
LPC47B37X
LPC47M10X
LPC47M120
LPC47M13X
LPC47M14X
LPC47N252
LPC47S42X

It was tested currently on my INSPIRON 8000, so feedbacks are welcome

I hope this patch will go in to the 2.4 tree...

Greetings

Sorry,

but i had a look on the irda homepage and it seems that there is nothing happening
since more than a year.

I will sent a copy of my patch to linux-irda@pasta.cs.uit.no and dag@brattli.net.

Greetings,
Stefani
