Joonsoo Kim ef93247325 mm, vmalloc: change iterating a vmlist to find_vm_area()
This patchset removes vm_struct list management after initializing
vmalloc.  Adding and removing an entry to vmlist is linear time
complexity, so it is inefficient.  If we maintain this list, overall
time complexity of adding and removing area to vmalloc space is O(N),
although we use rbtree for finding vacant place and it's time complexity
is just O(logN).

And vmlist and vmlist_lock is used many places of outside of vmalloc.c.
It is preferable that we hide this raw data structure and provide
well-defined function for supporting them, because it makes that they
cannot mistake when manipulating theses structure and it makes us easily
maintain vmalloc layer.

For kexec and makedumpfile, I export vmap_area_list, instead of vmlist.
This comes from Atsushi's recommendation.  For more information, please
refer below link.  https://lkml.org/lkml/2012/12/6/184

This patch:

The purpose of iterating a vmlist is finding vm area with specific virtual
address.  find_vm_area() is provided for this purpose and more efficient,
because it uses a rbtree.  So change it.

Gerald Schaefer 106c992a5e mm/hugetlb: add more arch-defined huge_pte functions
Commit abf09bed3c ("s390/mm: implement software dirty bits")
introduced another difference in the pte layout vs.  the pmd layout on
s390, thoroughly breaking the s390 support for hugetlbfs.  This requires
replacing some more pte_xxx functions in mm/hugetlbfs.c with a
huge_pte_xxx version.

This patch introduces those huge_pte_xxx functions and their generic
implementation in asm-generic/hugetlb.h, which will now be included on
all architectures supporting hugetlbfs apart from s390.  This change
will be a no-op for those architectures.

David Rientjes 4b59e6c473 mm, show_mem: suppress page counts in non-blockable contexts
On large systems with a lot of memory, walking all RAM to determine page
types may take a half second or even more.

In non-blockable contexts, the page allocator will emit a page allocation
failure warning unless __GFP_NOWARN is specified.  In such contexts, irqs
are typically disabled and such a lengthy delay may even result in NMI
watchdog timeouts.

To fix this, suppress the page walk in such contexts when printing the
page allocation failure warning.

Here's the big USB pull request for 3.10-rc1.
 
 Lots of USB patches here, the majority being USB gadget changes and
 USB-serial driver cleanups, the rest being ARM build fixes / cleanups,
 and individual driver updates.  We also finally got some chipidea fixes,
 which have been delayed for a number of kernel releases, as the
 maintainer has now reappeared.
 
 All of these have been in linux-next for a while.

Linus Torvalds 507ffe4f38 TTY/Serial driver update for 3.10-rc1
Here's the big tty/serial driver merge request for 3.10-rc1
 
 Once again, Jiri has a number of TTY driver fixes and cleanups, and
 Peter Hurley came through with a bunch of ldisc fixes that resolve a
 number of reported issues.  There are some other serial driver cleanups
 as well.
 
 All of these have been in the linux-next tree for a while.

Linus Torvalds 000a74f41e These are the pinctrl changes for v3.10:
- Patrice Chotard contributed a new configuration debugfs interface
   and reintroduced fine-grained locking into the core: instead of
   having a "big pinctrl lock" we have a per-controller lock and
   specialized locks for the global controller and pinctrl handle
   lists.
 - Haoijan Zhuang deleted all the PXA and MMP2 pinctrl drivers and
   replaced them with pinctrl-single (which is also used by other SoCs)
   so we are gaining consolidation. The platform particulars now come
   in through the device tree.
 - Haoijan also added support for generic pin config into the
   pinctrl-single driver which is another big consolidation win.
 - Finally also GPIO ranges are now supported by the pinctrl-single
   driver.
 - Tomasz Figa contributed a new Samsung S3C pinctrl driver, bringing
   more of the older Samsung platforms under the pinctrl umbrella and
   out of arch/arm.
 - Maxime Ripard contributed new Allwinner A10/A13 drivers.
 - Sachin Kamat, Wei Yongjun and Axel Lin did a lot of cleanups.

Merge tag 'stable/for-linus-3.10-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen

Pull Xen updates from Konrad Rzeszutek Wilk:
 "Features:
   - Populate the boot_params with EDD data.
   - Cleanups in the IRQ code.
  Bug-fixes:
   - CPU hotplug offline/online in PVHVM mode.
   - Re-upload processor PM data after ACPI S3 suspend/resume cycle."

And Konrad gets a gold star for sending the pull request early when he
thought he'd be away for the first week of the merge window (but because
of 3.9 dragging out to -rc8 he then re-sent the reminder on the first
day of the merge window anyway)

Linus Torvalds 4cbbd1d55d ARM: arm-soc fixes for 3.9
A late-arriving fix for musb on OMAP4, resolving an issue where the musb
 IP won't be clocked and thus not functional. Small in scope, most of the
 lines changed is a longish comment.
