The ttm bo now initially has NULL bo->resource, and leaves the driver
the handle that. However it looks like we forgot to handle that for qxl.
It looks like this will just null-ptr-deref in qxl_bo_move(), if
bo->resource is NULL.
Fix this by calling move_null() if the new resource is TTM_PL_SYSTEM,
otherwise do the multi-hop sequence to ensure can safely call into
ttm_bo_move_memcpy(), since it might also need to clear the memory.
This should give the same behaviour as before.

The fb_base in struct drm_mode_config has been unused for a long time.
Some drivers set it and some don't leading to a very confusing state
where the variable can't be relied upon, because there's no indication
as to which driver sets it and which doesn't.
The only usage of fb_base is internal to two drivers so instead of trying
to force it into all the drivers to get it into a coherent state
completely remove it.

Details:
Currently, when trying to suspend and resume with qxl device，
there are some error messages after resuming,
eventually caused to black screen and can't be recovered.
The first error message:
[ 64.668577][ C3] [drm] driver is in bug mode
This error is due to guest qxl driver
will call qxl_reinit_memslots(qdev) during system resume,
but didn't call qxl_io_reset(qdev) before this,
Then will cause the QXL_IO_MEMSLOT_ADD operation to fail on QEMU,
qxl->guest_bug flag will be set，As a result,
the QXL device can't communicate with guest qxl driver through the IO port.
after fix the first error,can success to resume and login to desktop,
but shortly after that will observe the second error message :
[ 353.095343][ T863] qxl 0000:00:02.0: object_init failed for (262144, 0x00000001)
[ 353.096660][ T863] [drm:qxl_gem_object_create [qxl]] *ERROR* Failed to allocate GEM object (260852, 1, 4096, -12)
[ 353.097277][ T863] [drm:qxl_alloc_ioctl [qxl]] *ERROR* qxl_alloc_ioctl: failed to create gem ret=-12
[ 368.197538][ T863] qxl 0000:00:02.0: object_init failed for (3149824, 0x00000001)
[ 368.197541][ T863] [drm:qxl_alloc_bo_reserved [qxl]] *ERROR* failed to allocate VRAM BO
The problem is caused by calling qxl_ring_init_hdr(qdev->release_ring)
in qxl_drm_resume() function.
When do QXL_IO_RESET,QEMU will call init_qxl_ram(),
so params like prod,cons,notify_on_cons and notify_on_prod
will be set to default value.
Ring push/pop actions for release_ring can be performed normally.
But call qxl_ring_init_hdr(qdev->release_ring)
will eventually set notify_on_prod to number of QXL_RELEASE_RING_SIZE,
affect the value of notify in qxl_push_free_res() function always be false,
QEMU will no longer send events of QXL_INTERRUPT_DISPLAY to the
guest qxl driver，so qxl_ring_pop() will never been called anymore，
and can't do dma_fence_signal(),result to ttm_bo_wait_ctx(bo, ctx)
always return EBUSY,fail to call qxl_bo_create().
Test scenario:
1) start virtual machine with qemu command "-device qxl-vga"
2) click suspend botton to enter suspend mode
3) resume and observe the error message in kernel logs,screen will be black
Let's fix this by reset io and remove the qxl_ring_init_hdr calling.

Rename struct dma_buf_map to struct iosys_map and corresponding APIs.
Over time dma-buf-map grew up to more functionality than the one used by
dma-buf: in fact it's just a shim layer to abstract system memory, that
can be accessed via regular load and store, from IO memory that needs to
be acessed via arch helpers.
The idea is to extend this API so it can fulfill other needs, internal
to a single driver. Example: in the i915 driver it's desired to share
the implementation for integrated graphics, which uses mostly system
memory, with discrete graphics, which may need to access IO memory.
The conversion was mostly done with the following semantic patch:

The "nomodeset" kernel cmdline parameter is handled by the vgacon driver
but the exported vgacon_text_force() symbol is only used by DRM drivers.
It makes much more sense for the parameter logic to be in the subsystem
of the drivers that are making use of it.
Let's move the vgacon_text_force() function and related logic to the DRM
subsystem. While doing that, rename it to drm_firmware_drivers_only() and
make it return true if "nomodeset" was used and false otherwise. This is
a better description of the condition that the drivers are testing for.

Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's
IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers
don't benefit from using it.

The function qxl_gem_prime_mmap() returns an error. The two callers
of gem_prime_mmap are drm_fbdev_fb_mmap() and drm_gem_dmabuf_mmap(),
which both already handle NULL-callbacks with an error code. So clear
gem_prime_mmap in qxl and remove qxl_gem_prime_mmap().

Print the name of the DRM driver when taking over fbdev devices. Makes
the output to dmesg more consistent. Note that the driver name is only
used for printing a string to the kernel log. No UAPI is affected by this
change.

When the comment needs to state explicitly that this is doesn't get a reference

When we want to decouble resource management from buffer management we need to
be able to handle resources separately.
Add a resource pointer and rename bo->mem so that all code needs to
change to access the pointer instead.

The section "19) Editor modelines and other cruft" in
Documentation/process/coding-style.rst clearly says, "Do not include any
of these in source files."
I recently receive a patch to explicitly add a new one.
Let's do treewide cleanups, otherwise some people follow the existing code
and attempt to upstream their favoriate editor setups.
It is even nicer if scripts/checkpatch.pl can check it.
If we like to impose coding style in an editor-independent manner, I think
editorconfig (patch [1]) is a saner solution.
