How about a patch? I needed the kernel up and running, so I came up with
the obvious patch. I don't have no time to fix this assumed abuse.
I should also note, that this patch wasn't enough to bring RBTX4938 kernel
back to life since rbhma4500_defconfig is broken somewhere so the kernel
doesn't output anything on the colsole). If I have some more time, I'll try to
investigate what exactly was causing this (I have a working .config)...
WBR, Sergei
