If a driver's Linux mmap callback passed vm_page_prot through unchanged, then linux_dev_mmap_single() would try to apply whatever VM_MEMATTR_xxx value 0 is to the mapping. On x86, VM_MEMATTR_DEFAULT is the PAT value for write-back (WB) which is 6, while 0 maps to the PAT value for uncacheable (UC). Thus, any mmap request that did not explicitly set page_prot was tried to map memory as UC triggering the warning in sg_pager_getpages().

An early fdclose() call can cause fget_unlocked() to fail. 2016-01-04T09:37:05Z Hans Petter Selasky hselasky@FreeBSD.org 2016-01-04T09:37:05Z urn:sha1:934e403c1255b369abd906a9b41075d58f41a359 Update the LinuxKPI: - Add more functions and types. - Implement ACCESS_ONCE(), WRITE_ONCE() and READ_ONCE(). - Implement sleepable RCU mechanism using shared exclusive locks. - Minor workqueue cleanup: - Make some functions global instead of inline to ease debugging. - Fix some minor style issues. - In the zero delay case in queue_delayed_work() use the return value from taskqueue_enqueue() instead of reading "ta_pending" unlocked and also ensure the callout is stopped before proceeding. - Implement drain_workqueue() function. - Reduce memory consumption when allocating kobject strings in the LinuxKPI. Compute string length before allocating memory instead of using fixed size allocations. Make kobject_set_name_vargs() global instead of inline to save some bytes when compiling.

This is needed so when running under Xen the calls to pci_child_added can be intercepted and a custom Xen method can be used to register those devices with Xen. This should not include any functional change, since the Xen implementation will be added in a following patch and the native implementation is a noop.
