This is continuation of development of a proposed earlier
functionality to have multiple gen_pools per device, see
https://lkml.org/lkml/2015/6/8/588 discussion.
The main difference with the originally sent change is that instead of
adding two new interfaces gen_pool_get_named() and
This change modifies gen_pool_get() and devm_gen_pool_create()

object.
Due to implementation gen_pool_get() is capable to retrieve only one
gen_pool associated with a device even if multiple gen_pools are
created, fortunately right at
Conversion to the use of pinned pfns made some functions unused. Remove

get_vaddr_frames() is used by relatively rare drivers so hide it and the
related functions behind a config option that is selected only by
drivers that need the infrastructure.

Convert omap_vout_uservirt_to_phys() to use get_vaddr_pfns() instead of
hand made mapping of virtual address to physical address. Also the
function leaked page reference from get_user_pages() so fix that by

called.

Currently vb2 core acquires mmap_sem just around call to
__qbuf_userptr(). However since commit f035eb4e976ef5 (videobuf2: fix
lockdep warning) it isn't necessary to acquire it so early as we no
longer have to drop queue mutex before acquiring mmap_sem. So push
acquisition of mmap_sem down into
Convert g2d_userptr_get_dma_addr() to pin pages using get_vaddr_frames().
This removes the knowledge about vmas and mmap_sem locking from exynos
driver. Also it fixes a problem that the function has been mapping user
provided address without holding mmap_sem.

Hello,
I'm sending the sixth version of my patch series to abstract vma handling from
