SCSI-related dead CONFIGs?

since things have stabilized after the merge window, any thoughts on the following useless(?) SCSI-related CONFIG vars? > ACORNSCSI_CONSTANTS drivers/scsi/arm/acornscsi.c:106:#undef CONFIG_ACORNSCSI_CONSTANTS drivers/scsi/arm/acornscsi.c:417:#ifdef CONFIG_ACORNSCSI_CONSTANTS drivers/scsi/ar

[PATCH 3/3] POWERPC: convert the IOMMU to use iova

This converts the PPC64 IOMMU to use iova for free area management. TODO: we might need to modify iova to use the tricks like avoiding cacheline bouncing. Performance tests are necessary. Signed-off-by: FUJITA Tomonori <[EMAIL PROTECTED]> --- arch/powerpc/kernel/iommu.c| 169 ++-

[PATCH -mm 0/3] convert IOMMUs to use iova

This patchset convert the PPC64 IOMMU to use the iova code for free area management. The IOMMUs ignores low level drivers' restrictions, the maximum segment size and segment boundary. I fixed the former: http://thread.gmane.org/gmane.linux.scsi/35602 The latter makes the free area management co

[PATCH 1/3] move iova from drivers/pci/ to lib/

iova could be used by several IOMMUs. This patch just moves iova from drivers/pci/ to lib/ and fixes the appropriate Makefile and Kconfig files. Signed-off-by: FUJITA Tomonori <[EMAIL PROTECTED]> --- arch/x86/Kconfig.x86_64 |1 + drivers/pci/Makefile |2 +- drivers/pci/intel-iommu.

You, as a Dell representative, will need to address changes in Firmware or other options for these adapters to the Adaptec representative on site. This patch does NOT impose a performance hit on consumers investing on more than 4G of Memory, what it does is prevent SCSI pass-through calls from /de

[PATCH 2/3] move iova cache code to iova.c

This detaches iova cache code from intel-iommu.c to iova.c in order to enable IOMMUs to use iova code. Signed-off-by: FUJITA Tomonori <[EMAIL PROTECTED]> --- drivers/pci/intel-iommu.c | 14 ++ include/linux/iova.h |6 +++--- lib/iova.c| 34
