2009-01-03AMD IOMMU: add protection domain flagsJoerg Roedel
Imapct: add a new struct member to 'struct protection_domain' When using protection domains for dma_ops and KVM its better to know for which subsystem it was allocated. Add a flags member to struct protection domain for that purpose. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

Impact: save unneeded logic to add and remove domains to the list The removal of a protection domain from the iommu_pd_list is not necessary.

Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-02sparc: drop get_tbr() in traps.hSam Ravnborg
get_tbr() has no users in the whole tree -drop it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-02sparc: fix warning in userspace header traps.hSam Ravnborg
Fix following warning: traps.h:23: extern's make no sense in userspace Add an ifdef __KERNEL__ block that cover the extern definition and a few related things that neither is for userspace. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-02sparc: fix warnings in userspace header byteorder.hSam Ravnborg
Fix following warnings in byteorder.h: byteorder.h:4: include of <linux/types.h> is preferred over <asm/types.h> byteorder.h:9: leaks CONFIG_SPARC32 to userspace where it is not valid byteorder.h:13: leaks CONFIG_SPARC64 to userspace where it is not valid byteorder.h:14: found __[us]{8,16,32,64} type without #include <linux/types.h> byteorder.h:47: leaks CONFIG_SPARC64 to userspace where it is not valid - changed to use include <linux/types.h> as suggested - use preprocessor defined symbols to distingush between 32 and 64 bit Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-02sparc: fix warning in userspace header jsflash.hSam Ravnborg
Fix following warnings in jsflash.h: jsflash.h:11: include of <linux/types.h> is preferred over <asm/types.h> jsflash.h:24: found __[us]{8,16,32,64} type without #include <linux/types.h> Fixed by changing the include to <linux/types.h> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-02sparc: unify openprom.hSam Ravnborg
After the preparational steps the unification was simple. The linux_prom_pci_registers definition did not look like it could be unified at first look since the structure is assigned using prop_getproperty() / of_get_property() so the structure is assumed to come direct form the prom. The LINUX_OPPROM_MAGIC was kept even if it is not used by the kernel on the assumption that userspace may require it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-02sparc64: delete unused linux_prom64_ranges from openprom_64.hSam Ravnborg

2009-01-02sparc: prepare openprom for unificationSam Ravnborg
Align the sparc and sparc64 versions so differences are minimal. A few data types are changed to better reflect there actual usage. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-02sparc: remove linux_prom_pci_assigned_addresses from openprom_32.hSam Ravnborg
It is not used anywhere in the tree so drop it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-02sparc: remove ebus definitions from openprom*.hSam Ravnborg

2009-01-02sparc: unify siginfo.hSam Ravnborg
Trivial unification where the sparc64 specific parts are protected using a signle ifdef/endif pair. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
