Commit 1fb9341ac3 ("module: put modules in list much earlier") moved
some of the module initialization code around, and in the process
changed the exit paths too. But for the duplicate export symbol error
case the change made the ddebug_cleanup path jump to after the module
mutex unlock, even though it happens with the mutex held.
Rusty has some patches to split this function up into some helper
functions, hopefully the mess of complex goto targets will go away
eventually.

if we have a move notify callback, when moving fails, we call move notify
the opposite way around, however this ends up with *mem containing the mm_node
from the bo, which means we double free it. This is a follow on to the previous
fix.

When we are using memcpy to move objects around, and we fail to memcpy
due to lack of memory to populate or failure to finish the copy, we don't
want to destroy the mm_node that has been copied into old_copy.
While working on a new kms driver that uses memcpy, if I overallocated bo's
up to the memory limits, and eviction failed, then machine would oops soon
after due to having an active bo with an already freed drm_mm embedded in it,
freeing it a second time didn't end well.

More important fixes for 3.9:
- error_state improvements to help debug the new scanline wait code added
for gen6+ - bug reports started popping up :( patch from Chris Wilson.
- fix a panel power sequence confusion between the eDP and lvds detection
code resulting in black screens - regression introduce in 3.8 (Jani
Nikula)
- Chris fixed the root-cause of the ilk relocation vs. evict bug.
- Another piece of cargo-culted rc6 lore from Jani, fixes up a regression
where a system refused to go into rc6 after suspend sometimes.

Operation-specific check (whether subvol is readonly or not) should go

Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
The error code that is returned in response to starting a mutually
exclusive operation when there is one already running got silently
changed from EINVAL to EINPROGRESS by 5ac00add. Returning EINPROGRESS
to, say, add_dev, when rm_dev is running is misleading. Furthermore,
the operation itself may want to use EINPROGRESS for other purposes.
Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
Balance pause/resume logic got broken by 5ac00add (went in into 3.8-rc1
as part of dev-replace merge). Offending commit took a stab at making
mutually exclusive volume operations (add_dev, rm_dev, resize, balance,
replace_dev) not block behind volume_mutex if another such operation is
in progress and instead return an error right away. Balancing front-end
relied on the blocking behaviour, so the fix is ugly, but short of a
complete rework, it's the best we can do.

During the migration to the common clock framework, calls to the
functions omap2xxx_clkt_vps_late_init() were not preserved for
OMAP2420 and OMAP2430. This causes the variables "sys_ck_rate" and
"curr_prcm_set" to be uninitialised on boot. On reboot, this causes the
following error message to be displayed because the appropriate MPU
clock frequency (derived from sys_ck_rate) cannot be found.
"Could not set MPU rate to 4294MHz"
Fix this by adding back calls to omap2xxx_clkt_vps_late_init() in the

This patch fixes the following:
WARNING: vmlinux.o(.text+0x1e709c): Section mismatch in reference from the funct
ion dma_controller_create() to the function .init.text:cppi_controller_start()
The function dma_controller_create() references
the function __init cppi_controller_start().
This is often because dma_controller_create lacks a __init
annotation or the annotation of cppi_controller_start is wrong.
This warning is there due to the deficiency in the commit 07a67bbb (usb: musb:
Make dma_controller_create __devinit).
Since the start() method is only called from musb_init_controller() which is
not annotated, drop '__init' annotation from cppi_controller_start() and also
cppi_pool_init() since it gets called from that function, to avoid another
section mismatch warning...
