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().

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 does not permit mapping larger regions (such as a PCI memory BAR) and it does not permit mapping addresses beyond the top of RAM (such as a 64-bit BAR located above the top of RAM). Instead of using a single OBJT_DEVICE object and passing the physaddr via the offset as a hack, create a new sglist and OBJT_SG object for each mmap request. The requested memory attribute is applied to the object thus affecting all pages mapped by the request.

Make function global instead of static inline to fix compiler warnings about passing variable argument lists to inline functions.

Move it to a C-file. - Fix problems about 32-bit ticks wraparound and unsigned long conversion. Jiffies or ticks in FreeBSD have integer type and are not long. - Add missing "order_base_2()" macro. - Fix BUILD_BUG_ON() macro. - Declare a missing symbol which is needed when compiling without -O2 - Clean up header file inclusions in the linux/completion.h, linux/in.h and linux/fs.h header files.

The update to OFED is nearly all additional defines and functions with the exception of the addition of additional parameters to ib_register_device() and the reg_user_mr callback. In addition the ibcore (Infiniband core) and ipoib (IP over Infiniband) have both been made into completely loadable modules to facilitate testing of the OFED stack in FreeBSD. Finally the Mellanox Infiniband drivers are now updated to the latest version shipping with Linux 3.7.
