| 45 functions for 2.5.68, 44 for 2.5.67. The new one is this:
| 0xc0881136 mxb_init_done: sub $0x51c,%esp
|
| Michael, are there any reasons not to make saa7740_init static, global
| or both? The memory is gone forever either way.
| Moreover, wouldn't this be a candidate for __init and __initdata
| respectively?
|
| Apart from that, patches for the marked (P) functions are in -je1, but
| might need some shaping up. Handle with care.
|
| Everything else remains unchanged since 2.5.67.
|
| 0xc05cff3c parport_config: sub $0x490,%esp
| 0xc0c12366 sw_connect: sub $0x490,%esp
| 0xc0c36c73 ixj_config: sub $0x484,%esp
| 0xc0c18ef1 uinput_alloc_device: sub $0x480,%esp
For PCMCIA/PC Card drivers (parport and ixj above), what context do the
pcmcia event handlers run in? Can they kmalloc()? with what gfp_flags?
I'll post patches for sw_connect() and uinput_alloc_device() shortly.

It is in 2.5.68-je2, which will be released later today if compilation
works.

Ok. It seems like a lot of people could do that. I've been grepping
for *_init* functions in a production kernel and found tons in the
.text section. Didn't look whether any of them could be moved, though.

Did I say Martin? Sorry about that.

^^^^^
That part bit me, the patch didn't apply without manual help. Maybe
you could use Andrew Mortons scripts or patcher, they really simplify
patch handling. (And save me lots of memory and disk space.)
Updated patch below, for the lazy ones. :)

Hello Jörn,
> 45 functions for 2.5.68, 44 for 2.5.67. The new one is this:

$0x51c,%esp

> Michael, are there any reasons not to make saa7740_init static, global

No, there are no reasons. Please apply my patch to drivers/media/video.
It does the following:
- make initialization data for helper chipsets (saa7111 and saa7740)
static and global
Additionally fixes:
- don't use irq driven i2c transfer when saa7740 is present (this screws
up the i2c bus and may hang the computer)
- add MODULE_DEVICE_TABLE to allow /sbin/hotplug to handle the device
> Moreover, wouldn't this be a candidate for __init and __initdata

Probably. I'll investigate this and include it in the next major update.

45 functions for 2.5.68, 44 for 2.5.67. The new one is this:
0xc0881136 mxb_init_done: sub $0x51c,%esp
Michael, are there any reasons not to make saa7740_init static, global
or both? The memory is gone forever either way.
Moreover, wouldn't this be a candidate for __init and __initdata
respectively?
Apart from that, patches for the marked (P) functions are in -je1, but
might need some shaping up. Handle with care.
Everything else remains unchanged since 2.5.67.
