+Description: Change NVKMS_USECS_TO_JIFFIES to pass unsigned long long to do_div
+ In kernel builds from 4.6 the compiler flags are more restrictive, and now
+ Werror=incompatible-pointer-types is passed, which causes the build to fail on
+ 32bit. do_div expects a 64 bit unsigned integer, but the NVKMS_USECS_TO_JIFFIES
+ macro passes an unsigned long. Use unsigned long long instead, and cast down
+ the result before returning. This macro is passed to time_mod which takes an
+ unsigned long as a parameter, so casting down is fine.

+Description: Undef CONFIG_XEN and CONFIG_XEN_DOM0 if building on ARM
+ Currently armmp kernel headers (3.16, 4.0, 4.1) have CONFIG_XEN enabled and
+ CONFIG_PARAVIRT disabled. This causes a build failure of the armhf dkms modules
+ in all current versions of the Nvidia driver.
+ Since running this driver on Xen is currently not supported anyway on Debian,
+ this patch undefines CONFIG_XEN and CONFIG_XEN_DOM0 if building on ARM, and
+ avoid including asm/maddr.h and xen/interface/memory.h.
+ Note that this has been tested only on qemu.
+ It is recommended to build an armmp kernel with CONFIG_XEN disabled (or with
+ CONFIG_XEN_PARAVIRT enabled) to use the Nvidia drivers.

+Description: fix module build failure for Linux 5.7
+ I was trying to test nvidia drivers with the new kernel in experimental
+ 5.7.0-rc5-686-pae. In the build log, I noticed it failed due to missing
+ functions set_memory_array_wb and friends. However, the code seemed to
+ be prepared for that possibility, so the problem must be the conftest.
+ .
+ I checked the output from the compilation checks and found some are
+ failing for the wrong reason, which causes some functions to be wrongly
+ detected as present (!) and some wrongly detected as missing. This would
+ probably apply to the other branches of nvidia drivers as well. I
+ prepared a patch for this, some comments:
+ .
+ - asm/page.h and asm/pgtable.h are needed for the pgprop_t type. Some
+ arches have here, some have it there. Otherwise the compilation
+ wrongly fails and detects the functions as present
+ .
+ - atomic_long_t is pulled by including linux/atomic.h, not
+ asm/atomic.h. Otherwise it's detected wrongly as absent
+ .
+ - linux/acpi.h is needed for acpi_status type
+ .
+ I checked that these files were present in the linux kernel since
+ 2.6.39, but haven't tested compilation with such old kernels. It should,
+ however, work.
