Add a "best_match" flag similar to the drm_mm_search_*() helpers so we
can convert TTM to use them in follow up patches. We can also inline the
non-generic helpers and move them into the header to allow compile-time
optimizations.
To make calls to drm_mm_{search,insert}_node() more readable, this
converts the boolean argument to a flagset. There are pending patches that
add additional flags for top-down allocators and more.
v2:
- use flag parameter instead of boolean "best_match"
- convert *_search_free() helpers to also use flags argument

We can apply the same optimisation tricks as kref_put_mutex() in our
local equivalent function. However, we have a different locking semantic
(we unlock ourselves, in kref_put_mutex() the callee unlocks) so that we
can use the same callbacks for both locked and unlocked kref_put()s and
so can not simply convert to using kref_put_mutex() directly.

When a BO gets pinned the placement may get changed. If the memory is
mapped into user space and user space has already accessed the mapped
range the page tables are set up but now point to the wrong memory.
Set bo.mdev->dev_mapping in mgag200_bo_create() to make sure that
ttm_bo_unmap_virtual() called from ttm_bo_handle_move_mem() will take
care of this.
v2: Don't call ttm_bo_unmap_virtual() in mgag200_bo_pin(), fix comment.

This is a cirrus version of Egbert Eich's patch for mgag200.
Without bo.bdev->dev_mapping set, the ttm_bo_unmap_virtual_locked
called from ttm_bo_handle_move_mem returns with no effect. If any
application accessed the memory before it was moved, it will
access wrong memory next time. This causes crashes when changing
resolution down.

All the gem based kms drivers really want the same function to
destroy a dumb framebuffer backing storage object.
So give it to them and roll it out in all drivers.
This still leaves the option open for kms drivers which don't use GEM
for backing storage, but it does decently simplify matters for gem
drivers.

Instead of using bit-banged I2C, let's use the actual I2C
driver in the kernel. Since the I2C block may be communicating
with things like the PMIC, we need to select it from the Kconfig
just like the bit-banged adapter is selected today. The rest of
the configuration for this driver can be done from the device

Some of my configs I test with have CONFIG_A11Y_BRAILLE_CONSOLE set.
When I started testing against v3.11-rc4 my console went bonkers. Using
ktest to bisect the issue, it came down to:
commit bbeddf52a "printk: move braille console support into separate
braille.[ch] files"
Looking into the patch I found the problem. It's with the return of
braille_register_console(). As anything other than NULL is considered a
failure.
But for those of us that have CONFIG_A11Y_BRAILLE_CONSOLE set but do not
define a "brl" or "brl=" on the command line, we still may want a
console that those with sight can still use.
Return NULL (success) if "brl" or "brl=" is not on the console line.

This commit even has the test-case to prove that the tracee

breakpoints before PTRACE_DETACH.
However, this is exactly what wineserver deliberately does,
set_thread_context() calls PTRACE_ATTACH + PTRACE_DETACH just
for PTRACE_POKEUSER(DR*) in between.
So we should revert this fix and document that PTRACE_DETACH
should keep the breakpoints.

unshare_userns(new_cred) does *new_cred = prepare_creds() before
create_user_ns() which can fail. However, the caller expects that
it doesn't need to take care of new_cred if unshare_userns() fails.
We could change the single caller, sys_unshare(), but I think it
would be more clean to avoid the side effects on failure, so with
this patch unshare_userns() does put_cred() itself and initializes
*new_cred only if create_user_ns() succeeeds.
