32-bit powerpc, aty128fb: vmap allocation for size 135168 failed

[Meelis Roos]

I was trying 4.13.0-rc5-00075-gac9a40905a61 on my PowerMac G4 with 1G 
RAM and after some time of sddm respawning and X trying to restart, 
dmesg is full of messages about vmap allocation failures.

Maybe the aty128fb is leaking ROM allocations or something like that?

sddm has been crashing eearlier too but I have not investigated it yet, 
but right after reboot the messages are about ATI ROM contents:

Aug 17 23:53:57 pohl kernel: [ 2940.146546] aty128fb 0000:00:10.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0x1111
Aug 17 23:54:02 pohl kernel: [ 2944.804838] aty128fb 0000:00:10.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0x1110

Then it changes to groups like this:
Aug 17 23:54:29 pohl kernel: [ 2971.514484] sddm[14093]: unhandled signal 11 at 00000090 nip 00000090 lr 0f55f858 code 30001

Aug 17 23:54:33 pohl kernel: [ 2976.295452] vmap allocation for size 3149824 failed: use vmalloc=<size> to increase size

And finally it becomes just vmalloc errors, no ATI ROM messages at all:
