Sven Schnelle c32c47aa36 parisc: Remove 32-bit DMA enforcement from sba_iommu This breaks booting from sata_sil24 with the recent DMA change. According to James Bottomley this was in to improve performance by kicking the device into 32 bit descriptors, which are usually more efficient, especially with older dual descriptor format cards like we have on parisc systems. Remove it for now to make DMA working again. Fixes: `dcc02c19cc` ("sata_sil24: use dma_set_mask_and_coherent") Signed-off-by: Sven Schnelle <svens@stackframe.org> Signed-off-by: Helge Deller <deller@gmx.de>		2019-10-14 21:44:26 +02:00

/*
** HP VISUALIZE Workstation PCI Bus Defect
**
** "HP has discovered a potential system defect that can affect
** the behavior of five models of HP VISUALIZE workstations when
** equipped with third-party or customer-installed PCI I/O expansion
** cards. The defect is limited to the HP C180, C160, C160L, B160L,
** and B132L VISUALIZE workstations, and will only be encountered
** when data is transmitted through PCI I/O expansion cards on the
** PCI bus. HP-supplied graphics cards that utilize the PCI bus are
** not affected."
