Hi,
When upgrading from v5.0 -> v5.1 on G4 PowerBook, I noticed WLAN does
not work anymore:
[ 42.004303] b43legacy-phy0: Loading firmware version 0x127, patch level 14
(2005-04-18 02:36:27)
[ 42.184837] b43legacy-phy0 debug: Chip initialized
[ 42.184873] b43legacy-phy0 ERROR: The machine/kernel does not support the
required 30-bit DMA mask
The same happens with the current mainline.
Bisected to:
commit 65a21b71f948406201e4f62e41f06513350ca390

powerpc/dma: remove dma_nommu_dma_supported
This function is largely identical to the generic version used
everywhere else. Replace it with the generic version.
