Now that the driver is in control of whether it needs to disable
everything at take-over or not, we can rip this all out.

This should be done in the drivers for two reasons:
- it gets in the way of fastboot efforts
- it links the fb helpers with the crtc helpers instead of going
through the real interface vfuncs, forcing i915 to fake all the
->disable callbacks used by the crtc helper to avoid ugly Oopsen
v2: Resolve conflicts since drivers still call
drm_fb_helper_single_add_all_connectors.

drm_fbdev_cma_init does the inital fbcon setup by calling down into

Not called by anyone, and really, shouldn't be. Drivers are supposed
either drm_fb_helper_initial_config or drm_fb_helper_hotplug_event.
Originally this was done differently, but is now consolidated in the
helper functions and no longer done by drivers directly.

drm/i915: restore only the mode of this driver on lastclose (v2)

It's only used internally for the sysrq and panic handlers provided by
the drm fb helper implementation. Hence just inline it, kill the
export and remove the confusing kerneldoc. Driver's are supposed to
call drm_fb_helper_restore_fbdev_mode on lastclose.
Note that locking is totally fubar - the sysrq case doesn't take any
locks at all. The panic handler probably shouldn't take any locks
since it'll only make things worse. Otoh it's probably better to
switch things over to the atomic modeset callbacks (and disable the
panic handler for those drivers which don't implement it).
But that's both better done in separate patches.

... it's required. Fix up exynos and the cma helper, and add a
corresponding WARN_ON to drm_fb_helper_restore_fbdev_mode.
Note that tegra calls the fbdev cma helper restore function also from
it's driver-load callback. Which is a bit against current practice,
since usually the call is only from ->lastclose, and initial setup is
done by drm_fb_helper_initial_config.
Also add the relevant drm DocBook entry.
v2: Add promised WARN to restore_fbdev_mode.

Use PCI Express Capability access functions to simplify this code a bit.
For non-PCIe devices or pre-PCIe 3.0 devices that don't implement the Link

For devices that conform to PCIe r3.0 and have a Link Capabilities 2

DRM_PCIE_SPEED_25 and DRM_PCIE_SPEED_50 in the returned mask.
For pre-r3.0 devices, the Link Capabilities 0010b encoding
(PCI_EXP_LNKCAP_SLS_5_0GB) means that both 5.0GT/s and 2.5GT/s are

Instead of reimplementing all of the dma_buf functionality in every driver,
create helpers drm_prime_import and drm_prime_export that implement them in
terms of new, lower-level hook functions:
gem_prime_pin: callback when a buffer is created, used to pin buffers into GTT
gem_prime_get_sg_table: convert a drm_gem_object to an sg_table for export
gem_prime_import_sg_table: convert an sg_table into a drm_gem_object
gem_prime_vmap, gem_prime_vunmap: map and unmap an object
These hooks are optional; drivers can opt in by using drm_gem_prime_import and
drm_gem_prime_export as the .gem_prime_import and .gem_prime_export fields of
struct drm_driver.
v2:
- Drop .begin_cpu_access. None of the drivers this code replaces implemented
it. Having it here was a leftover from when I was trying to include i915 in
this rework.
- Use mutex_lock instead of mutex_lock_interruptible, as these three drivers
did. This patch series shouldn't change that behavior.
- Rename helpers to gem_prime_get_sg_table and gem_prime_import_sg_table.
Rename struct sg_table* variables to 'sgt' for clarity.
- Update drm.tmpl for these new hooks.
v3:
- Pass the vaddr down to the driver. This lets drivers that just call vunmap on
the pointer avoid having to store the pointer in their GEM private structures.
- Move documentation into a /** DOC */ comment in drm_prime.c and include it in
drm.tmpl with a !P line. I tried to use !F lines to include documentation of
the individual functions from drmP.h, but the docproc / kernel-doc scripts
barf on that file, so hopefully this is good enough for now.
- apply refcount fix from commit be8a42ae60addd8b6092535c11b42d099d6470ec

Okay so Alan's patch handled the case where there was no registered fbcon,
however the other path entered in set_con2fb_map pit.
In there we called fbcon_takeover, but we also took the console lock in a couple
of places. So push the console lock out to the callers of set_con2fb_map,
this means fbmem and switcheroo needed to take the lock around the fb notifier
entry points that lead to this.
This should fix the efifb regression seen by Maarten.

As we use a variable length the compiler does not realise that it is a
fixed value of either 2 or 4 bytes. Instead of performing the inline
comparison itself, the compiler inserts a function call to the generic
memcmp routine which is optimised for long comparisons of variable
length. That turns out to be quite expensive...

Okay you don't really want to use udl devices as your console, but if
you are unlucky enough to do so, you run into a lot of schedule while atomic
due to printk being called from all sorts of funky places. So check if we
are in an atomic context, and queue the damage for later, the next printk
should cause it to appear. This isn't ideal, but it is simple, and seems to
work okay in my testing here.

If grub2 loads efifb/vesafb, then when systemd starts it can set the console
font on that framebuffer device, however when we then load the native KMS
driver, the first thing it does is tear down the generic framebuffer driver.
The thing is the generic code is doing the right thing, it frees the font
because otherwise it would leak memory. However we can assume that if you
are removing the generic firmware driver (vesa/efi/offb), that a new driver
*should* be loading soon after, so we effectively leak the font.
However the old code left a dangling pointer in vc->vc_font.data and we
can now reuse that dangling pointer to load the font into the new
driver, now that we aren't freeing it.

When we switch from 256->512 byte font rendering mode, it means the
current contents of the screen is being reinterpreted. The bit that holds
the high bit of the 9-bit font, may have been previously set, and thus
the new font misrenders.
The problem case we see is grub2 writes spaces with the bit set, so it
ends up with data like 0x820, which gets reinterpreted into 0x120 char
which the font translates into G with a circumflex. This flashes up on
screen at boot and is quite ugly.
A current side effect of this patch though is that any rendering on the
screen changes color to a slightly darker color, but at least the screen
no longer corrupts.
v2: as suggested by hpa, always clear the attribute space, whether we
are are going to or from 512 chars.

Pull radeon fixes from Dave Airlie:
"I got these late last week, the main chunks of these fix a rendering
regression since 3.7, and the settle ones all fix the issue where we
don't wait long enough for the memory controller to settle after
turning it off which causes bad memory reads, they all fix real users
bugs, and most of them are destined for stable.
Can't remember if you had net connection on that island :-)"
I don't know if the "two tin-cans and a string" thing here on "that
island" can really be considered internet, but I guess I can pull
things. Barely.

drm/radeon: switch back to the CP ring for VM PT updates

Pull scsi target fixes from Nicholas Bellinger:
"Here's the current set of v3.8-rc fixes in the target-pending.git
queue. Apologies in advance for these missing the -rc6 release, and
having to be destined for -rc7 code.
The majority of these patches are regression bugfixes specific to
v3.8-rc code changes, namely the zero-length CDB handling breakage
after the sense_reason_t conversion, and preventing configfs port
linking for unconfigured devices after the recent struct
se_subsystem_dev removal. These is also one (the divide by zero bug
for unconfigured devices) that is CC'ed to stable."
* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
target: Fix divide by zero bug in fabric_max_sectors for unconfigured devices
target: Fix regression allowing unconfigured devices to fabric port link
tcm_vhost: fix pr_err on early kick
target: Fix zero-length READ_CAPACITY_16 regression
target: Fix zero-length MODE_SENSE regression
target: Fix zero-length INQUIRY additional sense code regression
