Bug Description
=== SRU Justification ===
[Impact]
Callers vmalloc_32() expect the page is not located in highmem.
All users of vmalloc_32() have this issue, module saa7146 is one of
them.
[Test]
saa7146 crashes at probing. The issue is fixed with the patch.
[Fix]
Add GFP_DMA32 to GFP_VMALLOC32 flag for 32bits systems.
The patch is in stable trees, so only Artful needs this patch.
[Regression Potential]
Low. It's a crucial fix for 32bits systems.
=== Original Bug Report ===
After upgrading to 17.10 (from 16.04 with 4.4 kernel) my PCI DVB card Terratec Cinergy DVB-1200 with SAA7146 chipset is not working anymore. There is a kernel bug message while booting and no /dev/dvb device is created. Tried also with newest mainline 4.14 kernel - same error.
