ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig Acked-by: Arnd Bergmann

parisc: Disable HP HSC-PCI Cards to prevent kernel crash

2019-09-08T13:43:04Z

The HP Dino PCI controller chip can be used in two variants: as on-board controller (e.g. in B160L), or on an Add-On card ("Card-Mode") to bridge PCI components to systems without a PCI bus, e.g. to a HSC/GSC bus. One such Add-On card is the HP HSC-PCI Card which has one or more DEC Tulip PCI NIC chips connected to the on-card Dino PCI controller. Dino in Card-Mode has a big disadvantage: All PCI memory accesses need to go through the DINO_MEM_DATA register, so Linux drivers will not be able to use the ioremap() function. Without ioremap() many drivers will not work, one example is the tulip driver which then simply crashes the kernel if it tries to access the ports on the HP HSC card. This patch disables the HP HSC card if it finds one, and as such fixes the kernel crash on a HP D350/2 machine. Signed-off-by: Helge Deller Noticed-by: Phil Scarr Cc: stable@vger.kernel.org
