Unofficial patches for Mali Midgard GPU r17p0 kernel drivers on 4.12.0-rcX kernels

Greetings,

The new kernel 4.12 series has started and for all the ealier adopters who want to use these kernels with Mali Midgard GPU support, here are the patches needed to compile such kernels with the Mali Midgard r17p0 drivers, after copying the driver package content in the kernel base directory :

• https://github.com/Miouyouyou/MyyQi/blob/master/patches/Mali/r17p0-01rel0/0001-Midgard-daptation-to-Linux-4.10.0-rcX-signatures.patch
• https://github.com/Miouyouyou/MyyQi/blob/master/patches/Mali/r17p0-01rel0/0002-UMP-Adapt-get_user_pages-calls.patch
• https://github.com/Miouyouyou/MyyQi/blob/master/patches/Mali/r17p0-01rel0/0003-Renamed-Kernel-DMA-Fence-structures-and-functions.patch
• https://github.com/Miouyouyou/MyyQi/blob/master/patches/Mali/r17p0-01rel0/0004-Few-modifications-after-v4.11-headers-and-signatures.patch
• https://github.com/Miouyouyou/MyyQi/blob/master/patches/Mali/r17p0-01rel0/0005-Using-the-new-header-on-4.12-kernels-for-copy_-_user.patch

These patches are due to the following mainline kernel changes :

• generic ...copy_..._user primitives
  Introduced in Linux : 4.12
• mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf
  Introduced in Linux : 4.11
• sched/headers: Move task->mm handling methods to <linux/sched/mm.h>
  Introduced in Linux : 4.11
• sched/headers: Move task-stack related APIs from <linux/sched.h> to <linux/sched/task_stack.h>
  Introduced in Linux : 4.11
• dma-buf: Rename struct fence to dma_fence
  Introduced in Linux : 4.9
• mm: add locked parameter to get_user_pages_remote()
  Introduced in Linux : 4.10
• ktime: Get rid of the union
  Introduced in Linux : 4.10
• mm: use vmf->address instead of of vmf->virtual_address
  Introduced in Linux : 4.10
• mm, dax, gpu: convert vm_insert_mixed to pfn_t
  Introduced in Linux : 4.5

The patches required to enable the compilation of Mali Midgard GPU drivers and UMP drivers, after copying the drivers package TX011-SW-99002-r17p0-01rel0/driver/product/kernel/ content in your linux kernel base directory, are available here .

• https://github.com/Miouyouyou/MyyQi/blob/master/patches/kernel/v4.12/0003-Post-Mali-Kernel-device-drivers-modifications.patch
• https://github.com/Miouyouyou/MyyQi/blob/master/patches/kernel/v4.12/0004-Post-Mali-UMP-integration.patch

A full kernel download, patch and compilation procedure for MiQi RK3288 ARMv7 boards is available here : https://github.com/Miouyouyou/MyyQi .
The procedure includes the download of the Linux 4.12-rc1 kernel and the Mali r17p0-00rel0 kernel drivers.
