Wen Congyang 8732794b16 numa: convert static memory to dynamically allocated memory for per node device
We use a static array to store struct node.  In many cases, we don't have
too many nodes, and some memory will be unused.  Convert it to per-device
dynamically allocated memory.

Wen Congyang 97d0da2204 memory-hotplug: fix NR_FREE_PAGES mismatch
NR_FREE_PAGES will be wrong after offlining pages.  We add/dec
NR_FREE_PAGES like this now:

1. move all pages in buddy system to MIGRATE_ISOLATE, and dec NR_FREE_PAGES

2. don't add NR_FREE_PAGES when it is freed and the migratetype is
   MIGRATE_ISOLATE

3. dec NR_FREE_PAGES when offlining isolated pages.

4. add NR_FREE_PAGES when undoing isolate pages.

When we come to step 3, all pages are in MIGRATE_ISOLATE list, and
NR_FREE_PAGES are right.  When we come to step4, all pages are not in
buddy system, so we don't change NR_FREE_PAGES in this step, but we change
NR_FREE_PAGES in step3.  So NR_FREE_PAGES is wrong after offlining pages.
So there is no need to change NR_FREE_PAGES in step3.

This patch also fixs a problem in step2: if the migratetype is
MIGRATE_ISOLATE, we should not add NR_FRR_PAGES when we remove pages from
pcppages.

Wen Congyang 7c72eb3272 memory-hotplug: auto offline page_cgroup when onlining memory block failed
When a memory block is onlined, we will try allocate memory on that node
to store page_cgroup.  If onlining the memory block failed, we don't
offline the page cgroup, and we have no chance to offline this page cgroup
unless the memory block is onlined successfully again.  It will cause that
we can't hot-remove the memory device on that node, because some memory is
used to store page cgroup.  If onlining the memory block is failed, there
is no need to stort page cgroup for this memory.  So auto offline
page_cgroup when onlining memory block failed.

Wen Congyang b023f46813 memory-hotplug: skip HWPoisoned page when offlining pages
hwpoisoned may be set when we offline a page by the sysfs interface
/sys/devices/system/memory/soft_offline_page or
/sys/devices/system/memory/hard_offline_page. If we don't clear
this flag when onlining pages, this page can't be freed, and will
not in free list. So we can't offline these pages again. So we
should skip such page when offlining pages.

Yasuaki Ishimatsu fa7194eb99 memory hotplug: suppress "Device memoryX does not have a release() function" warning
When calling remove_memory_block(), the function shows following message
at device_release().

"Device 'memory528' does not have a release() function, it is broken and
must be fixed."

The reason is memory_block's device struct does not have a release()
function.

So the patch registers memory_block_release() to the device's release()
function for suppressing the warning message.  Additionally, the patch
moves kfree(mem) into the release function since the release function is
prepared as a means to free a memory_block struct.

Rabin Vincent 377e4f1676 mm: show migration types in show_mem
This is useful to diagnose the reason for page allocation failure for
cases where there appear to be several free pages.

Example, with this alloc_pages(GFP_ATOMIC) failure:

 swapper/0: page allocation failure: order:0, mode:0x0
 ...
 Mem-info:
 Normal per-cpu:
 CPU    0: hi:   90, btch:  15 usd:  48
 CPU    1: hi:   90, btch:  15 usd:  21
 active_anon:0 inactive_anon:0 isolated_anon:0
  active_file:0 inactive_file:84 isolated_file:0
  unevictable:0 dirty:0 writeback:0 unstable:0
  free:4026 slab_reclaimable:75 slab_unreclaimable:484
  mapped:0 shmem:0 pagetables:0 bounce:0
 Normal free:16104kB min:2296kB low:2868kB high:3444kB active_anon:0kB
 inactive_anon:0kB active_file:0kB inactive_file:336kB unevictable:0kB
 isolated(anon):0kB isolated(file):0kB present:331776kB mlocked:0kB
 dirty:0kB writeback:0kB mapped:0kB shmem:0kB slab_reclaimable:300kB
 slab_unreclaimable:1936kB kernel_stack:328kB pagetables:0kB unstable:0kB
 bounce:0kB writeback_tmp:0kB pages_scanned:0 all_unreclaimable? no
 lowmem_reserve[]: 0 0

Before the patch, it's hard (for me, at least) to say why all these free
chunks weren't considered for allocation:

 Normal: 0*4kB 0*8kB 0*16kB 0*32kB 0*64kB 0*128kB 1*256kB 1*512kB
 1*1024kB 1*2048kB 3*4096kB = 16128kB

After the patch, it's obvious that the reason is that all of these are
in the MIGRATE_CMA (C) freelist:

 Normal: 0*4kB 0*8kB 0*16kB 0*32kB 0*64kB 0*128kB 1*256kB (C) 1*512kB
 (C) 1*1024kB (C) 1*2048kB (C) 3*4096kB (C) = 16128kB

Linus Torvalds 414a6750e5 USB patches for 3.8-rc1
Here's the big set of USB patches for 3.8-rc1.
 
 Lots of USB host driver cleanups in here, and a bit of a reorg of the
 EHCI driver to make it easier for the different EHCI platform drivers to
 all work together nicer, which was a reduction in overall code.  We also
 deleted some unused firmware files, and got rid of the very old
 file_storage usb gadget driver that had been broken for a long time.
 This means we ended up removing way more code than added, always a nice
 thing to see:

 Other than that, the usual set of new device ids, driver fixes, gadget
 driver and controller updates and the like.

Linus Torvalds 6a5971d8fe Char/Misc driver merge for 3.8-rc1
Here is the "big" char/misc driver patches for 3.8-rc1.  I'm starting to
 put random driver subsystems that I had previously sent you through the
 driver-core tree in this tree, as it makes more sense to do so.
 
 Nothing major here, the various __dev* removals, some mei driver
 updates, and other random driver-specific things from the different
 maintainers and developers.
 
 Note, some MFD drivers got added through this tree, and they are also
 coming in through the "real" MFD tree as well, due to some major
 mis-communication between me and the different developers.  If you have
 any merge conflicts, take the ones from the MFD tree, not these ones,
 sorry about that.
 
 All of this has been in linux-next for a while.

Linus Torvalds cff2f741b8 Driver core updates for 3.8-rc1
Here's the large driver core updates for 3.8-rc1.
 
 The biggest thing here is the various __dev* marking removals.  This is
 going to be a pain for the merge with different subsystem trees, I know,
 but all of the patches included here have been ACKed by their various
 subsystem maintainers, as they wanted them to go through here.
 
 If this is too much of a pain, I can pull all of them out of this tree
 and just send you one with the other fixes/updates and then, after
 3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
 it's up to you.  The merges should all be trivial, and Stephen has been
 doing them all in linux-next for a few weeks now quite easily.
 
 Other than the __dev* marking removals, there's nothing major here, some
 firmware loading updates and other minor things in the driver core.
 
 All of these have (much to Stephen's annoyance), been in linux-next for
 a while.

Linus Torvalds 505cbedab9 This is the pinctrl big pull request for v3.8.
As can be seen from the diffstat the major changes
 are:
 
 - A big conversion of the AT91 pinctrl driver and
   the associated ACKed platform changes under
   arch/arm/max-at91 and its device trees. This
   has been coordinated with the AT91 maintainers
   to go in through the pinctrl tree.
 
 - A larger chunk of changes to the SPEAr drivers
   and the addition of the "plgpio" driver for the
   SPEAr as well.
 
 - The removal of the remnants of the Nomadik driver
   from the arch/arm tree and fusion of that into
   the Nomadik driver and platform data header files.
 
 - Some local movement in the Marvell MVEBU drivers,
   these now have their own subdirectory.
 
 - The addition of a chunk of code to gpiolib under
   drivers/gpio to register gpio-to-pin range mappings
   from the GPIO side of things. This has been
   requested by Grant Likely and is now implemented,
   it is particularly useful for device tree work.
 
 Then we have incremental updates all over the place,
 many of these are cleanups and fixes from Axel Lin
 who has done a great job of removing minor mistakes
 and compilation annoyances.

Pavel Shilovsky c299dd0e2d CIFS: Fix write after setting a read lock for read oplock files
If we have a read oplock and set a read lock in it, we can't write to the
locked area - so, filemap_fdatawrite may fail with a no information for a
userspace application even if we request a write to non-locked area. Fix
this by populating the page cache without marking affected pages dirty
after a successful write directly to the server.

Also remove CONFIG_CIFS_SMB2 ifdefs because it's suitable for both CIFS
and SMB2 protocols.

This should fix a regression that was introduced when the new mount
option parser went in. Also, when the unc= and prefixpath= options
are provided, check their values against the ones we parsed from
the device string. If they differ, then throw a warning that tells
the user that we're using the values from the unc= option for now,
but that that will change in 3.10.

Jeff Layton 839db3d10a cifs: fix up handling of prefixpath= option
Currently the code takes care to ensure that the prefixpath has a
leading '/' delimiter. What if someone passes us a prefixpath with a
leading '\\' instead? The code doesn't properly handle that currently
AFAICS.

Let's just change the code to skip over any leading delimiter character
when copying the prepath. Then, fix up the users of the prepath option
to prefix it with the correct delimiter when they use it.

Also, there's no need to limit the length of the prefixpath to 1k. If
the server can handle it, why bother forbidding it?

Jeff Layton 62a1a439e0 cifs: clean up handling of unc= option
Make sure we free any existing memory allocated for vol->UNC, just in
case someone passes in multiple unc= options.

Get rid of the check for too long a UNC. The check for >300 bytes seems
arbitrary. We later copy this into the tcon->treeName, for instance and
it's a lot shorter than 300 bytes.

Eliminate an extra kmalloc and copy as well. Just set the vol->UNC
directly with the contents of match_strdup.

Establish that the UNC should be stored with '\\' delimiters. Use
convert_delimiter to change it in place in the vol->UNC.

Finally, move the check for a malformed UNC into
cifs_parse_mount_options so we can catch that situation earlier.

Vitaly Andrianov 4009793e15 drivers: cma: represent physical addresses as phys_addr_t
This commit changes the CMA early initialization code to use phys_addr_t
for representing physical addresses instead of unsigned long.

Without this change, among other things, dma_declare_contiguous() simply
discards any memory regions whose address is not representable as unsigned
long.

This is a problem on 32-bit PAE machines where unsigned long is 32-bit
but physical address space is larger.

Marek Szyprowski 387870f2d6 mm: dmapool: use provided gfp flags for all dma_alloc_coherent() calls
dmapool always calls dma_alloc_coherent() with GFP_ATOMIC flag,
regardless the flags provided by the caller. This causes excessive
pruning of emergency memory pools without any good reason. Additionaly,
on ARM architecture any driver which is using dmapools will sooner or
later  trigger the following error:
"ERROR: 256 KiB atomic DMA coherent pool is too small!
Please increase it with coherent_pool= kernel parameter!".
Increasing the coherent pool size usually doesn't help much and only
delays such error, because all GFP_ATOMIC DMA allocations are always
served from the special, very limited memory pool.

This patch changes the dmapool code to correctly use gfp flags provided
by the dmapool caller.

Mike Turquette 7c045a55c9 clk: introduce optional disable_unused callback
Some gate clocks have special needs which must be handled during the
disable-unused clocks sequence.  These needs might be driven by software
due to the fact that we're disabling a clock outside of the normal
clk_disable path and a clk's enable_count will not be accurate.  On the
other hand a specific hardware programming sequence might need to be
followed for this corner case.

This change is needed for the upcoming OMAP port to the common clock
framework.  Specifically, it is undesirable to treat the disable-unused
path identically to the normal clk_disable path since other software
layers are involved.  In this case OMAP's clockdomain code throws WARNs
and bails early due to the clock's enable_count being set to zero.  A
custom callback mitigates this problem nicely.
