Stack usage for functions in kernel 2.4.21 [SuSE] (worst case 2.8kB !)

[Roger Larsson]

Hi developers,

Is your function among these? Do you really need that much stack?

(This is a follow up to my <<UPD: "do_IRQ: near stack overflow" when inserting 
CF disk>> i since than learned about the checkstack tool by Jörn Engel)

The reason for some functions to show up twice is probably due to 
kernel/external pcmcia.
