Here is a list for 2.1.27. This is a kernel with everything compiled in,
"everything" meaning: everything that compiles at all. Especially in
drivers/net and drivers/isdn there is a lot of stuff that makes problems (and
some of those files include stdlib.h and stdio.h! Argh!)

c3c de4x5_ioctl
c2c ewrk3_ioctl

Better pray that no interrupts happen...

c0300873 <reorder+6f> subl %ecx,%esp
c030084c <reorder+48> subl %eax,%esp
c02e2d97 <reorder+6f> subl %ecx,%esp
c02e2d70 <reorder+48> subl %eax,%esp
c02661ea <DumpData+1e> subl %eax,%esp
c01bc0ef <ncp_rename+3b> subl %eax,%esp
c01bc0d8 <ncp_rename+24> subl %eax,%esp
c01bbf71 <ncp_unlink+21> subl %eax,%esp
c01bbe0d <ncp_rmdir+21> subl %eax,%esp
c01bbc86 <ncp_mkdir+2a> subl %eax,%esp
c01bba53 <ncp_create+27> subl %eax,%esp
c01bb4dc <ncp_lookup+34> subl %eax,%esp
c01a8925 <nfs_lookup+2d> subl %eax,%esp

Someone might want to have a look at the ncp_* functions, I checked one and
it didn't seem to do any size checks.
