This patch makes do_mincore() use walk_page_vma(), which reduces many lines
of code by using common page table walk code.
ChangeLog v5:
- fix buffer overflow
ChangeLog v4:
- remove redundant vma
ChangeLog v3:
- add NULL vma check in mincore_unmapped_range()
- don't use pte_entry()
ChangeLog v2:
Current implementation of page table walker has a fundamental problem
in vma handling, which started when we tried to handle vma(VM_HUGETLB).
Because it's done in pgd loop, considering vma boundary makes code
complicated and bug-prone.
>From the users viewpoint, some user checks some vma-related c
This series is ver.6 of page table walker patchset.
I just rebased this onto mmotm-2014-07-30-15-57 with no major change.
Trinity shows no bug at least in my environment.

Currently no user of page table walker sets ->pgd_entry() or ->pud_entry(),
so checking their existence in each loop is just wasting CPU cycle.
So let's remove it to reduce overhead.

pagewalk.c can handle vma in itself, so we don't have to pass vma via
walk->private. And show_smap() walks pages on vma basis, so using
walk_page_vma() is preferable.

Page table walker has the information of the current vma in mm_walk, so
we don't have to call find_vma() in each pagemap_hugetlb_range() call.
NULL-vma check is omitted because we assume that we never run hugetlb_entry()
callback on the address without vma. And even if it were broken, null pointer
clear_refs_write() has some prechecks to determine if we really walk over
a given vma. Now we have a test_walk() callback to filter vmas, so let's
utilize it.
ChangeLog v5:
- remove unused vma
ChangeLog v4:
- use walk_page_range instead of walk_page_vma with for loop

We don't have to use mm_walk->private to pass vma to the callback function
because of mm_walk->vma. And walk_page_vma() is useful if we walk over a
single vma.

pagewalk.c can handle vma in itself, so we don't have to pass vma via
walk->private. And both of mem_cgroup_count_precharge() and
mem_cgroup_move_charge() do for each vma loop themselves, but now it's
done in pagewalk.c, so let's clean up them.

The idea of the framework is to provide consistent ways of
programming raw images into FPGA's.
Programming from device tree overlays is supported.
The core (fpga-mgr.c) does not include a userspace interface
and just exports kernel functions.
From: Alan Tull
Add basic sysfs interface. Only exports two files:
/sys/class/fpga_manager/fpga0/name
Name of low level driver.
/sys/class/fpga_manager/fpga0/status
status of fpga framework as returned by core
fpga-mgr.c's fpga_mgr_ops_framework_status
function or by the low level
From: Alan Tull
This driver allows programming the fpga from
device tree overlays.
This code is dependent on Pantelis Antoniou's current
work on Device Tree overlays, a method of dynamically
altering the kerel's live Device Tree. This patchset

Hi Linus,
A single fix to not invoke the espfix code on Xen PV, as it turns out
to oops the guest when invoked after all. This patch leaves some
amount of dead code, in particular unnecessary initialization of the
espfix stacks when they won't be used, but in the interest of keeping
the patch min

Actually, are you sure ida framework is a good idea here? AFAICT, you
only use it to keep track of used minors.

There's no need for a simple-bus, place the smsc,usb3503a directly into
the root node. That's what we're going to do on exynos5250-spring.

Hi,
this series adds mapping color control to the generic kmap code, allowing
architectures with aliasing VIPT cache to use high memory. There's also
use example of this new interface by xtensa.
Changes since v3:
- drop #include from mm/highmem.c as it's done in
linux/highmem.h;
- add 'User-vi
Define ARCH_PKMAP_COLORING and provide corresponding macro definitions
on cores with aliasing data cache.
Instead of single last_pkmap_nr maintain an array last_pkmap_nr_arr of
pkmap counters for each page color. Make sure that kmap maps physical
page at virtual address with color matching its phy

User-visible effect:
Architectures that choose this method of maintaining cache coherency
(MIPS and xtensa currently) are able to use high memory on cores with
aliasing data cache. Without this fix such architectures can not use
high memory (in case of xtensa it means that at most 128 MBytes of
