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().

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 td_fpop pointer is not valid when a cdevpriv destructor is run, and the type-specific close method has already been called, so f_vnode may not be valid (and the vnode might have been recycled without our own reference). 2012-10-01T06:42:07Z Hans Petter Selasky hselasky@FreeBSD.org 2012-10-01T06:42:07Z urn:sha1:38e19f6b6c17ab84a2c7673e075e29d4016748e2 Streamline use of cdevpriv and correct some corner cases. 2011-08-16T20:07:47Z Konstantin Belousov kib@FreeBSD.org 2011-08-16T20:07:47Z urn:sha1:9c00bb9190391479885cfb14ed23fb7003d10109 to implement fchown(2) and fchmod(2) support for several file types that previously lacked it.
