* add map/unmap_single_attr and map/unmap_sg_attr to struct dma_mapping_opsFUJITA Tomonori2009-01-061-0/+14
| | | | | | | | | | | | | | This adds map/unmap_single_attr and map/unmap_sg_attr to struct dma_mapping_ops. This enables us to move the dma operations in struct ia64_machine_vector to struct dma_mapping_ops. Note that we will remove map/unmap_sg and map/umap_single. This is a preparation of struct dma_mapping_ops unification.

This is plain wrong, the architectures that support VIRT_CPU_ACCOUNTING=y can do better: distinguish between the time spent doing nothing and the time spent by idle doing work. The first is accounted with account_idle_time and the second with account_system_time. The architectures that use the account_xxx_time interface directly and not the account_xxx_ticks interface now need to do the check for the idle process in their arch code. In particular to improve the system vs true idle time accounting the arch code needs to measure the true idle time instead of just testing for the idle process. To improve the tick based accounting as well we would need an architecture primitive that can tell us if the pt_regs of the interrupted context points to the magic instruction that halts the cpu. In addition idle time is no more added to the stime of the idle process. This field now contains the system time of the idle process as it should be. On systems without VIRT_CPU_ACCOUNTING this will always be zero as every tick that occurs while idle is running will be accounted as idle time. This patch contains the necessary common code changes to be able to distinguish idle system time and true idle time. The architectures with support for VIRT_CPU_ACCOUNTING need some changes to exploit this. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

On s390 the calls to account_user_time_scaled and account_system_time_scaled never have been added. In addition system time that is accounted as guest time to the user time of a process is accounted to the scaled system time instead of the scaled user time. To fix the bugs and to prevent future forgetfulness this patch merges account_system_time_scaled into account_system_time and account_user_time_scaled into account_user_time.

Move them to a central location. Twists: 1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a CONFIG_INIT_ALL_POSSIBLE for this rather than break them. 2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'. Those archs simply have phys_cpu_present_map replaced everywhere. 3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky so I just manipulate them both in sync. 4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map' declarations.

Old versions could never have worked since they required pointers to be set in the ioctl payload which were never being set by the ioctl handler for get_regs. In addition reserve extra space for future extensions. The change of layout of struct kvm_regs doesn't require adding a new CAP since get/set regs never worked on ia64 until now. This version doesn't support copying the KVM kernel stack in/out of the kernel. This should be implemented in a seperate ioctl call if ever needed.
