| | | | | | | | | | | | | | | | | | | | | | | | | | | | Further incorporation of generic irq framework. Replacing __do_IRQ() by proper flow handler would make the irq handling path a bit simpler and faster. * use generic_handle_irq() instead of __do_IRQ(). * use handle_level_irq for obvious level-type irq chips. * use handle_percpu_irq for irqs marked as IRQ_PER_CPU. * setup .eoi routine for irq chips possibly used with handle_percpu_irq.

| * [MIPS] IRQ cleanupsAtsushi Nemoto2006-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a big irq cleanup patch. * Use set_irq_chip() to register irq_chip. * Initialize .mask, .unmask, .mask_ack field. Functions for these method are already exist in most case. * Do not initialize .startup, .shutdown, .enable, .disable fields if default routines provided by irq_chip_set_defaults() were suitable. * Remove redundant irq_desc initializations. * Remove unnecessary local_irq_save/local_irq_restore, spin_lock. With this cleanup, it would be easy to switch to slightly lightwait irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ(). Though whole this patch is quite large, changes in each irq_chip are not quite simple. Please review and test on your platform. Thanks.

| | | | | | | | | | | | | | | | | | | | This patch introduces __pa_symbol() macro which should be used to calculate the physical address of kernel symbols.

| | | | | | | | | | | | | | | | | | | | During early boot mem init, some configs couldn't use __pa() to convert virtual into physical addresses. Specially for 64 bit kernel cases when CONFIG_BUILD_ELF64=n. This patch make __pa() work for _all_ configs and thus make CPHYSADDR() useless.

| * [MIPS] page.h: remove __pa() usages.Franck Bui-Huu2006-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __pa() was used by virt_to_page() and virt_addr_valid(). These latter are used when kernel is initialised so __pa() is not appropriate, we use virt_to_phys() instead. Futhermore __pa() is going to take care of CKSEG0/XKPHYS address mix for 64 bit kernels. This makes __pa() more complex than virt_to_phys() and this extra work is not needed by virt_to_page() and virt_addr_valid(). Eventually it consolidates virt_to_phys() prototype by making its argument 'const'. this avoids some warnings that was due to some virt_to_page() usages which pass const pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new object class and permission validation scheme that validates against the defined kernel headers. This scheme allows extra classes and permissions that do not conflict with the kernel definitions to be added to the policy. This validation is now done for all policy loads, not just subsequent loads after the first policy load. The implementation walks the three structrures containing the defined object class and permission values and ensures their values are the same in the policy being loaded. This includes verifying the object classes themselves, the permissions they contain, and the permissions they inherit from commons. Classes or permissions that are present in the kernel but missing from the policy cause a warning (printed to KERN_INFO) to be printed, but do not stop the policy from loading, emulating current behavior. Any other inconsistencies cause the load to fail. Signed-off-by: Chad Sellers <csellers@tresys.com> Acked-by: Stephen Smalley <sds@tycho.nsa.gov> Signed-off-by: James Morris <jmorris@namei.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Makes the key argument passed into hashtab_search and all the functions it calls constant. These functions include hash table function pointers hash_value and keycmp. The only implementations of these currently are symhash and symcmp, which do not modify the key. The key parameter should never be changed by any of these, so it should be const. This is necessary to allow calling these functions with keys found in kernel object class and permission definitions.

| * | | IB/ehca: Use WQE offset instead of WQE addr for pending work reqsHoang-Nam Nguyen2006-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a patch for ehca to fix a bug in prepare_sqe_to_rts(), which used WQE address to iterate pending work requests. This might cause an access violation since the queue pages can not be assumed to follow each other consecutively. Thus, this patch introduces a few queue functions to determine WQE offset based on its address and uses WQE offset to iterate the pending work requests.

| * | | RDMA/iwcm: Fix comment for iwcm_deref_id() to match codeKrishna Kumar2006-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In iwcm_deref_id(), the comment says : "If the last reference is being removed and iw_destroy_cm_id is waiting, wake up the waiting thread". The second part of the comment, "and iw_destroy_cm_id is waiting," is wrong, since this function either wakes the waiter already waiting in iwcm_deref_id, or enables it (so that when wait_for_completion() is performed later, it will immediately return).
