If the firmware is not builtin and userspace is not yet running, we can
stall the boot process for a minute whilst the firmware loader times
out. This is contrary to expectations of providing a builtin EDID!

In the process, we can rearrange the code to make the error handling
more resilient and prevent gcc warning about unitialised variables along
the error paths.

v3: Verify that we do not read beyond the end of the fwdata (Ville)

Analog to drm_dev_register(), we now provide drm_dev_unregister() which
does the reverse. drm_dev_put() is still in place and combines the calls
to drm_dev_unregister() and drm_dev_free() so buses don't have to change.

*_get() and *_put() are used for reference-counting in the kernel.
However, drm_dev_put() definitely does not do any kind of ref-counting.
Hence, use the more appropriate *_register(), *_unregister(), *_alloc()
and *_free() names.

The error paths in DRM bus drivers currently leak memory as they don't
correctly revert drm_dev_alloc(). Introduce drm_dev_free() to free DRM
devices which haven't been registered, yet.

We must be careful not to introduce any side-effects with cleanups done in
drm_dev_free(). drm_ht_remove(), drm_ctxbitmap_cleanup() and
drm_gem_destroy() are all fine in that regard.

Try to keep all functions that handle DRM file_operations in drm_fops.c
so internal helpers can be marked static later.

This makes the split between the 3 core files more obvious:
 - drm_stub.c: DRM device allocation/destruction and management
 - drm_fops.c: DRM file_operations (except for ioctl)
 - drm_drv.c: Global DRM init + ioctl handling
Well, ioctl handling is still spread throughout hundreds of source files,
but at least the others are clearly defined this way.

All bus drivers do device setup themselves. This requires us to adjust all
of them if we introduce new core features. Thus, merge all these into a
uniform drm_dev_register() helper.

Note that this removes the drm_lastclose() error path for AGP as it is
horribly broken. Moreover, no bus driver called this in any other error
path either. Instead, we use the recently introduced AGP cleanup helpers.

We also keep a DRIVER_MODESET condition around pci_set_drvdata() to keep
semantics.

Instead of managing device allocation+initialization in each bus-driver,
we should do that in a central place. drm_fill_in_dev() already does most
of it, but also requires the global drm lock for partial AGP device
registration.

Split both apart so we have a clean device initialization/allocation
phase, and a registration phase.

All drivers embed gem-objects into their own buffer objects. There is no
reason to keep drm_gem_object_alloc(), gem->driver_private and

New drivers are highly encouraged to do the same. There is no benefit in
allocating gem-objects separately.

There is no reason to keep the gem object separately allocated. nouveau is
the last user of gem_obj->driver_private, so if we embed it, we can get
rid of 8bytes per gem-object.

The implementation follows the radeon driver. bo->gem is only valid, iff
the bo was created via the gem helpers _and_ iff the user holds a valid
gem reference. That is, as the gem object holds a reference to the
nouveau_bo. If you use nouveau_ref() to gain a bo reference, you are not
guaranteed to also hold a gem reference. The gem object might get
destroyed after the last user drops the gem-ref via
drm_gem_object_unreference(). Use drm_gem_object_reference() to gain a
gem-reference.

For debugging, we can use bo->gem.filp != NULL to test whether a gem-bo is
valid. However, this shouldn't be used for real functionality to avoid
gem-internal dependencies.

Note that the implementation follows the previous style. However, we no
longer can check for bo->gem != NULL to test for a valid gem object. This
wasn't done before, so we should be safe now.

Ben Herrenschmidt found that commit 928bea96 ("PCI: Delay enabling
bridges until they're needed") breaks PCI in some powerpc environments.

The reason is that the PCIe port driver will call pci_enable_device() on
the bridge, so the device is enabled, but skips pci_set_master because
pcie_port_auto and no acpi on powerpc.

Because of that, pci_enable_bridge() later on (called as a result of the
child device driver doing pci_enable_device) will see the bridge as
already enabled and will not call pci_set_master() on it.

Fixed by add checking in pci_enable_bridge, and call pci_set_master
if driver skip that.

That will make the code more robot and wade off problem for missing
pci_set_master in drivers.

	There's a bunch of failure exits in ffs_fs_mount() with
seriously broken recovery logics.  Most of that appears to stem
from misunderstanding of the ->kill_sb() semantics; unlike
->put_super() it is called for *all* superblocks of given type,
no matter how (in)complete the setup had been.  ->put_super()
is called only if ->s_root is not NULL; any failure prior to
setting ->s_root will have the call of ->put_super() skipped.
->kill_sb(), OTOH, awaits every superblock that has come from
sget().

Current behaviour of ffs_fs_mount():

We have struct ffs_sb_fill_data data on stack there.  We do
	ffs_dev = functionfs_acquire_dev_callback(dev_name);
and store that in data.private_data.  Then we call mount_nodev(),
passing it ffs_sb_fill() as a callback.  That will either fail
outright, or manage to call ffs_sb_fill().  There we allocate an
instance of struct ffs_data, slap the value of ffs_dev (picked
from data.private_data) into ffs->private_data and overwrite
data.private_data by storing ffs into an overlapping member
(data.ffs_data).  Then we store ffs into sb->s_fs_info and attempt
to set the rest of the things up (root inode, root dentry, then
create /ep0 there).  Any of those might fail.  Should that
happen, we get ffs_fs_kill_sb() called before mount_nodev()
returns.  If mount_nodev() fails for any reason whatsoever,
we proceed to
	functionfs_release_dev_callback(data.ffs_data);

That's broken in a lot of ways.  Suppose the thing has failed in
allocation of e.g. root inode or dentry.  We have
	functionfs_release_dev_callback(ffs);
	ffs_data_put(ffs);
done by ffs_fs_kill_sb() (ffs accessed via sb->s_fs_info), followed by
	functionfs_release_dev_callback(ffs);
from ffs_fs_mount() (via data.ffs_data).  Note that the second
functionfs_release_dev_callback() has every chance to be done to freed memory.

Suppose we fail *before* root inode allocation.  What happens then?
ffs_fs_kill_sb() doesn't do anything to ffs (it's either not called at all,
or it doesn't have a pointer to ffs stored in sb->s_fs_info).  And
	functionfs_release_dev_callback(data.ffs_data);
is called by ffs_fs_mount(), but here we are in nasal daemon country - we
are reading from a member of union we'd never stored into.  In practice,
we'll get what we used to store into the overlapping field, i.e. ffs_dev.
And then we get screwed, since we treat it (struct gfs_ffs_obj * in
disguise, returned by functionfs_acquire_dev_callback()) as struct
ffs_data *, pick what would've been ffs_data ->private_data from it
(*well* past the actual end of the struct gfs_ffs_obj - struct ffs_data
is much bigger) and poke in whatever it points to.

FWIW, there's a minor leak on top of all that in case if ffs_sb_fill()
fails on kstrdup() - ffs is obviously forgotten.

The thing is, there is no point in playing all those games with union.
Just allocate and initialize ffs_data *before* calling mount_nodev() and
pass a pointer to it via data.ffs_data.  And once it's stored in
sb->s_fs_info, clear data.ffs_data, so that ffs_fs_mount() knows that
it doesn't need to kill the sucker manually - from that point on
we'll have it done by ->kill_sb().

The put_device(dev) at the bottom of the loop of device_shutdown
may result in the dev being cleaned up. In device_create_release,
the dev is kfreed.

However, device_shutdown attempts to use the dev pointer again after
put_device by referring to dev->parent.

Copy the parent pointer instead to avoid this condition.

This bug was found on Chromium OS's chromeos-3.8, which is based on v3.8.11.
See bug report : https://code.google.com/p/chromium/issues/detail?id=297842
This can easily be reproduced when shutting down with
hidraw devices that report battery condition.
Two examples are the HP Bluetooth Mouse X4000b and the Apple Magic Mouse.
For example, with the magic mouse :
The dev in question is "hidraw0"
dev->parent is "magicmouse"

In the course of the shutdown for this device, the input event cleanup calls
a put on hidraw0, decrementing its reference count.
When we finally get to put_device(dev) in device_shutdown, kobject_cleanup
is called and device_create_release does kfree(dev).
dev->parent is no longer valid, and we may crash in
put_device(dev->parent).

This change should be applied on any kernel with this change :
