Patch for compiling v384.98 modules with Linux v4.14.9+

Greetings,

There has been some kernel headers reordering in Linux v4.14.9 and this caused the modules for the NVIDIA v384.98 drivers to fail to compile for me. Here is a patch allowing to fix this issue:

Same build issue, for v387.22 (short term)

...
/src/nvidia/NVIDIA-Linux-x86_64-387.22-no-compat32/kernel/nvidia-uvm/uvm8_va_block.c: In function ‘block_cpu_fault_locked’:
/usr/src/linux-4.14.9-2.g9423ca2/arch/x86/include/asm/processor.h:826:39: error: implicit declaration of function ‘task_stack_page’; did you mean ‘task_stack_vm_area’? [-Werror=implicit-function-declaration]
  unsigned long __ptr = (unsigned long)task_stack_page(task); \
...                                       ^

Fix above,

...
+#include <linux/sched/task_stack.h>
...

works for v387.22 as well.

Too much went into 4.14.9
Some was reverted before releasing 4.14.9
So far one patch is pending a revert https://lkml.org/lkml/2017/12/26/306
They need to be more strict over what goes into -stable trees.

Interesting piece of info, thank you !

Well, it is unrelated with our issue here, since that pending revert affects IPv6 networking.

I was indeed surprised that a micro release bump of the Linux kernel caused such a havoc in headers…

I guess reverting to v4.14.8 till the mess gets sorted out is the wisest approach…

I ran into this issue on Ubuntu 16.04 with the HWE kernels.

The patch is no more needed for current kernel (4.14.14) and driver (384.111).

7

16.04 only has kernel version 4.13

Ouch, 4.13 kernel sources (ubuntu 16.04) are not compatible with nvidia driver.

Even after the fix, I am getting a new error:

You need to add the include file and macro for it to work. I had the same issue.
