The CONFIG_EXPERIMENTAL config item has not carried much meaning for a

ad2e632966 usb: fixes for v3.8-rc5
Finally we have a build fix for fsl-mxc-udc UDC driver.
 
 We also have a fix for ep0 maxburst setting on DWC3
 which could confuse the HW if we tell it we had way
 too many streams on that endpoint when it _has_ to be
 only one.
 
 cppi_dma support for MUSB got a fix when running as a
 module. By dropping the wrong __init annotation, the
 function will be available even when we're modules and
 we're done with .init.text section.
 
 Last, but not least, we have a fix on FunctionFS which
 was causing a bug on our option parsing algorithm.

Otherwise we will get:

The function omap_init_ocp2scp() references

c1bf08ac26 ftrace: Be first to run code modification on modules
If some other kernel subsystem has a module notifier, and adds a kprobe
to a ftrace mcount point (now that kprobes work on ftrace points),
when the ftrace notifier runs it will fail and disable ftrace, as well
as kprobes that are attached to ftrace points.

Here's the error:

 ftrace failed to modify [<ffffffffa0180000>] init_once+0x0/0x20 [fat]
  actual: cc:bb:d2:4b:e1

A kprobe was added to the init_once() function in the fat module on load.
But this happened before ftrace could have touched the code. As ftrace
didn't run yet, the kprobe system had no idea it was a ftrace point and
simply added a breakpoint to the code (0xcc in the cc:bb:d2:4b:e1).

Then when ftrace went to modify the location from a call to mcount/fentry
into a nop, it didn't see a call op, but instead it saw the breakpoint op
and not knowing what to do with it, ftrace shut itself down.

The solution is to simply give the ftrace module notifier the max priority.
This should have been done regardless, as the core code ftrace modification
also happens very early on in boot up. This makes the module modification
closer to core modification.

85de7fac39 i2c: mxs: Fix misuse init_completion
The init_completion() call does reinit not only the variable carrying
the flag that the completion finished, but also initialized the
waitqueue associated with the completion. On the contrary, the
INIT_COMPLETION() call only reinits the flag.

In case there was anything still stuck in the waitqueue, subsequent call
to init_completion() would be able to create possible race condition. This
patch uses the proper function and moves init_completion() into .probe() call
of the driver, to be issued only once.

Note that such scenario is impossible, since two threads can never enter the
mxs_i2c_xfer_msg(), since whole this section is protected by mutex in I2C core.
This by no means allows this issue to exit though.

This happens because sockets do not define the removexattr operation.
Before removing the xattr, verify the removexattr function pointer is
not NULL.

e3e2775ced cifs: fix srcip_matches() for ipv6
srcip_matches() previously had code like this:

  srcip_matches(..., struct sockaddr *rhs) {
    /* ... */
    struct sockaddr_in6 *vaddr6 = (struct sockaddr_in6 *) &rhs;
    return ipv6_addr_equal(..., &vaddr6->sin6_addr);
  }

which interpreted the values on the stack after the 'rhs' pointer as an
ipv6 address.  The correct thing to do is to use 'rhs', not '&rhs'.

ee61abb322 module: fix missing module_mutex unlock
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.

014b34409f ttm: on move memory failure don't leave a node dangling
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.

630541863b ttm: don't destroy old mm_node on memcpy failure
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.

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.

Subhash Jadavani reported this partial backtrace:
  Now consider this call stack from MMC block driver (this is on the ARMv7
  based board):

  [<c001b50c>] (v7_dma_inv_range+0x30/0x48) from [<c0017b8c>] (dma_cache_maint_page+0x1c4/0x24c)

This is caused by incrementing the struct page pointer, and running off
the end of the sparsemem page array.  Fix this by incrementing by pfn
instead, and convert the pfn to a struct page.

bdcc612752 ARM: OMAP2: Fix missing omap2xxx_clkt_vps_late_init function calls
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

2f91ec8cc4 asm-generic, mm: pgtable: convert my_zero_pfn() to macros to fix build
Commit 816422ad76 ("asm-generic, mm: pgtable: consolidate zero page
helpers") broke the compile on MIPS if SPARSEMEM is enabled.  We get
this:

  In file included from arch/mips/include/asm/pgtable.h:552,
                   from include/linux/mm.h:44,
                   from arch/mips/kernel/asm-offsets.c:14:
  include/asm-generic/pgtable.h: In function 'my_zero_pfn':
  include/asm-generic/pgtable.h:466: error: implicit declaration of function 'page_to_section'
  In file included from arch/mips/kernel/asm-offsets.c:14:
  include/linux/mm.h: At top level:
  include/linux/mm.h:738: error: conflicting types for 'page_to_section'
  include/asm-generic/pgtable.h:466: note: previous implicit declaration of 'page_to_section' was here

Due header files inter-dependencies, the only way I see to fix it is
convert my_zero_pfn() for __HAVE_COLOR_ZERO_PAGE to macros.
