Historically, the top three bytes of personality have been used for
things such as ADDR_NO_RANDOMIZE, which made sense only for specific
architectures.
We now however have a flag there that is general no matter the
architecture (UNAME26); generally we have to be careful to preserve the
personality flags across exec().
This patch fixes tile architecture not to forcefully overwrite
personality flags during exec().
In addition to that, we fix two other things along the way:
- exec_domain switching is fixed -- set_personality() should always
be used instead of directly assigning to current->personality.
- as pointed out by Arnd Bergmann, PER_LINUX_32BIT is not used anywhere
by tile, so let's just drop that in favor of PER_LINUX

The PA-RISC tool chain seems to have some problem with correct

sections are fixed up for other architecture to only contain truly
read-only data.
Disable const sections for PA-RISC

Pull preparatory patches for user API disintegration from David Howells:
"The patches herein prepare for the extraction of the Userspace API
bits from the various header files named in the Kbuild files.
New subdirectories are created under either include/uapi/ or
arch/x/include/uapi/ that correspond to the subdirectory containing
that file under include/ or arch/x/include/.
The new subdirs under the uapi/ directory are populated with Kbuild
files that mostly do nothing at this time. Further patches will
disintegrate the headers in each original directory and fill in the
Kbuild files as they do it.
These patches also:
(1) fix up #inclusions of "foo.h" rather than <foo.h>.
(2) Remove some redundant #includes from the DRM code.
(3) Make the kernel build infrastructure handle Kbuild files both in
the old places and the new UAPI place that both specify headers
to be exported.
(4) Fix some kernel tools that #include kernel headers during their
build.
I have compile tested this with allyesconfig against x86_64,
allmodconfig against i386 and a scattering of additional defconfigs of
other arches. Prepared for main script

There's no caller of pcibios_assign_resources() in the tree. It is
exported, so an out-of-tree module *could* call it, but no other arch
exports pcibios_assign_resources(), so it would have to be a CRIS-specific
module. I doubt such a caller exists.

Pull vfs update from Al Viro:
- big one - consolidation of descriptor-related logics; almost all of
that is moved to fs/file.c
(BTW, I'm seriously tempted to rename the result to fd.c. As it is,
we have a situation when file_table.c is about handling of struct
file and file.c is about handling of descriptor tables; the reasons
are historical - file_table.c used to be about a static array of
struct file we used to have way back).
A lot of stray ends got cleaned up and converted to saner primitives,
disgusting mess in android/binder.c is still disgusting, but at least
doesn't poke so much in descriptor table guts anymore. A bunch of
relatively minor races got fixed in process, plus an ext4 struct file
leak.
- related thing - fget_light() partially unuglified; see fdget() in
there (and yes, it generates the code as good as we used to have).
- also related - bits of Cyrill's procfs stuff that got entangled into
that work; _not_ all of it, just the initial move to fs/proc/fd.c and
switch of fdinfo to seq_file.
- Alex's fs/coredump.c spiltoff - the same story, had been easier to
take that commit than mess with conflicts. The rest is a separate
pile, this was just a mechanical code movement.
- a few misc patches all over the place. Not all for this cycle,
there'll be more (and quite a few currently sit in akpm's tree)."
Fix up trivial conflicts in the android binder driver, and some fairly
simple conflicts due to two different changes to the sock_alloc_file()
interface ("take descriptor handling from sock_alloc_file() to callers"
vs "net: Providing protocol type via system.sockprotoname xattr of
/proc/PID/fd entries" adding a dentry name to the socket)

prom_printf() takes printf style arguments. Specifing GCC's format
attribute reveals that there are several wrong usages of prom_printf().
This fixes those wrong format strings and arguments, and also leaves
format attributes in order to detect similar mistakes at compile time.

Pull CMA and DMA-mapping updates from Marek Szyprowski:
"This time the pull request is rather small, because the further
redesign patches were not ready on time.
This pull request consists of the patches which extend ARM DMA-mapping
subsystem with support for CPU coherent (ACP) DMA busses. The first
client of the new version is HighBank SATA driver. The second part of
the pull request includes various cleanup for both CMA common code and
ARM DMA-mapping subsystem."
Fix up trivial add-add conflict due to the "dma-coherent" DT property
being added next to the "calxeda,port-phys" property for the Calxeda
AHCI controller.
* 'for-v3.7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:
ARM: dma-mapping: Remove unsed var at arm_coherent_iommu_unmap_page
ARM: highbank: add coherent DMA setup
ARM: kill off arch_is_coherent
ARM: add coherent iommu dma ops
ARM: add coherent dma ops
ARM: dma-mapping: Refrain noisy console message
ARM: dma-mapping: Small logical clean up
drivers: dma-contiguous: refactor dma_alloc_from_contiguous()
This function is used by sparc, powerpc and arm64 for compat support.
The patch adds a generic implementation which calls do_sendfile()
directly and avoids set_fs().
The sparc architecture has wrappers for the sign extensions while
powerpc relies on the compiler to do the this. The patch adds wrappers
for powerpc to handle the u32->int type conversion.
compat_sys_sendfile64() can be replaced by a sys_sendfile() call since
compat_loff_t has the same size as off_t on a 64-bit system.
On powerpc, the patch also changes the 64-bit sendfile call from
sys_sendile64 to sys_sendfile.

Pull GPIO changes from Linus Walleij:
"So this is the LW GPIO patch stack for v3.7:
- refactoring from Thierry Redding at Arnd Bergmann's request to use
the seq_file iterator interface in gpiolib.
- A new driver for Avionic Design's N-bit GPIO expander.
- Two instances of mutexes replaced by spinlocks from Axel Lin to
code that is supposed to be fastpath compliant.
- IRQ demuxer and gpio_to_irq() support for pcf857x by Kuninori
Morimoto.
- Dynamic GPIO numbers, device tree support, daisy chaining and some
other fixes for the 74x164 driver by Maxime Ripard.
- IRQ domain and device tree support for the tc3589x driver by Lee
Jones.
- Some conversion to use managed resources devm_* code.
- Some instances of clk_prepare() or clk_prepare_enable() added to
support the new, stricter common clock framework.
- Some for_each_set_bit() simplifications.
- Then a lot of fixes as we fixed up all of the above tripping over
our own shoelaces and that kind of thing."

7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel
Borkmann.
8) Increate the loopback default MTU to 64K, from Eric Dumazet.
9) Use a per-task rather than per-socket page fragment allocator for
outgoing networking traffic. This benefits processes that have very
many mostly idle sockets, which is quite common.
From Eric Dumazet.
10) Use up to 32K for page fragment allocations, with fallbacks to
smaller sizes when higher order page allocations fail. Benefits are
a) less segments for driver to process b) less calls to page
allocator c) less waste of space.
From Eric Dumazet.
11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.
12) VXLAN device driver, one way to handle VLAN issues such as the
limitation of 4096 VLAN IDs yet still have some level of isolation.
From Stephen Hemminger.
13) As usual there is a large boatload of driver changes, with the scale
perhaps tilted towards the wireless side this time around.
Fix up various fairly trivial conflicts, mostly caused by the user
namespace changes.

Pull user namespace changes from Eric Biederman:
"This is a mostly modest set of changes to enable basic user namespace
support. This allows the code to code to compile with user namespaces
enabled and removes the assumption there is only the initial user
namespace. Everything is converted except for the most complex of the
filesystems: autofs4, 9p, afs, ceph, cifs, coda, fuse, gfs2, ncpfs,
nfs, ocfs2 and xfs as those patches need a bit more review.
The strategy is to push kuid_t and kgid_t values are far down into
subsystems and filesystems as reasonable. Leaving the make_kuid and
from_kuid operations to happen at the edge of userspace, as the values
come off the disk, and as the values come in from the network.
Letting compile type incompatible compile errors (present when user
namespaces are enabled) guide me to find the issues.
The most tricky areas have been the places where we had an implicit
union of uid and gid values and were storing them in an unsigned int.
Those places were converted into explicit unions. I made certain to
handle those places with simple trivial patches.
Out of that work I discovered we have generic interfaces for storing
quota by projid. I had never heard of the project identifiers before.
Adding full user namespace support for project identifiers accounts
for most of the code size growth in my git tree.
Ultimately there will be work to relax privlige checks from
"capable(FOO)" to "ns_capable(user_ns, FOO)" where it is safe allowing
root in a user names to do those things that today we only forbid to
non-root users because it will confuse suid root applications.
While I was pushing kuid_t and kgid_t changes deep into the audit code
I made a few other cleanups. I capitalized on the fact we process
netlink messages in the context of the message sender. I removed
usage of NETLINK_CRED, and started directly using current->tty.
Some of these patches have also made it into maintainer trees, with no
problems from identical code from different trees showing up in
linux-next.
After reading through all of this code I feel like I might be able to
win a game of kernel trivial pursuit."

Plumb the UAPI Kbuilds into the user header installation and checking system.
As the headers are split the entries will be transferred across from the old
Kbuild files to the UAPI Kbuild files.
The changes made in this commit are:
(1) Exported generated files (of which there are currently four) are moved to
uapi/ directories under the appropriate generated/ directory, thus we
get:
include/generated/uapi/linux/version.h
arch/x86/include/generated/uapi/asm/unistd_32.h
arch/x86/include/generated/uapi/asm/unistd_64.h
arch/x86/include/generated/uapi/asm/unistd_x32.h
These paths were added to the build as -I flags in a previous patch.
(2) scripts/Makefile.headersinst is now given the UAPI path to install from
rather than the old path.
It then determines the old path from that and includes that Kbuild also
if it exists, thus permitting the headers to exist in either directory
during the changeover.
I also renamed the "install" variable to "installdir" as it refers to a
directory not the install program.
(3) scripts/headers_install.pl is altered to take a list of source file paths
instead of just their names so that the makefile can tell it exactly
where to find each file.
For the moment, files can be obtained from one of four places for each
output directory:
.../include/uapi/foo/
.../include/generated/uapi/foo/
.../include/foo/
.../include/generated/foo/
The non-UAPI paths will be dropped later.

Differentiate the generated UAPI and internal headers during generation such
that the UAPI headers can be installed elsewhere.
A later patch will use this to move the UAPI headers to:
arch/x86/include/generated/uapi/asm/
to make them easier to handle.
A previous patch added a -I for this path.

Fix a build failure in the x86 insn_sanity program after the UAPI split. The
problem is that insn_sanity.c #includes arch/x86/lib/insn.c - which uses the
kernel string header. This leads to conflicts for various definitions against
the /usr/include/ headers.
linux/string.h can be replaced with the normal userspace string.h if __KERNEL__
is not specified.

Partition the header include path flags into two sets, one for kernelspace
builds and one for userspace builds.
Add the following directories to build after the ordinary include directories
so that #include will pick up the UAPI header directly if the kernel header
has been moved there.
The userspace set (represented by the USERINCLUDE make variable) contains:
-I $(srctree)/arch/$(hdr-arch)/include/uapi
-I arch/$(hdr-arch)/include/generated/uapi
-I $(srctree)/include/uapi
-I include/generated/uapi
-include $(srctree)/include/linux/kconfig.h
and the kernelspace set (represented by the LINUXINCLUDE make variable)
contains:
-I $(srctree)/arch/$(hdr-arch)/include
-I arch/$(hdr-arch)/include/generated
-I $(srctree)/include
-I include --- if not building in the source tree
plus everything in the USERINCLUDE set.
Then use USERINCLUDE in building the x86 boot code.

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
Tejun pointed out a few of them, I fixed a couple more.
