Subject: drm/amdgpu: fix non-ANSI declaration of
 amdgpu_amdkfd_gfx_*_get_functions()

amdgpu_amdkfd_gfx_7_get_functions and amdgpu_amdkfd_gfx_8_0_get_functions
have no parameters, so use the normal void parameter convention to make
them  match their prototypes in the header file
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h

Allows the user to force the supported pcie gen and lane
config on both the asic and the chipset.
Useful for debugging pcie problems and for virtualization
where we may not be able to query the pcie bridge caps.

Default to:
gen: chipset 1/2, asic 1/2/3
lanes: 1/2/4/8/16

v2: fix bare metal case

No need to re-init asic if it's already been initialized.
Skip IB tests since kernel processes are frozen in thaw.

Subject: drm/amdgpu: hold reference to fences in amdgpu_sa_bo_new (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An arbitrary amount of time can pass between spin_unlock and
fence_wait_any_timeout, so we need to ensure that nobody frees the
fences from under us.

A stress test (rapidly starting and killing hundreds of glxgears
instances) ran into a deadlock in fence_wait_any_timeout after
about an hour, and this race condition appears to be a plausible
cause.

v2: agd: rebase on upstream

Subject: drm/amdgpu: fix issue with overlapping userptrs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Otherwise we could try to evict overlapping userptr BOs in get_user_pages(),
leading to a possible circular locking dependency.

Subject: drm/amdgpu: use post-decrement in error handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We need to use post-decrement to get the pci_map_page undone also for
i==0, and to avoid some very unpleasant behaviour if pci_map_page
failed already at i==0.
