getname() is intended to copy pathname strings from userspace into a
kernel buffer. The result is just a string in kernel space. It would
however be quite helpful to be able to attach some ancillary info to
the string.
For instance, we could attach some audit-related info to reduce the
amount of audit-related processing needed. When auditing is enabled,
we could also call getname() on the string more than once and not
need to recopy it from userspace.
This patchset converts the getname()/putname() interfaces to return
a struct instead of a string. For now, the struct just tracks the
string in kernel space and the original userland pointer for it.
Later, we'll add other information to the struct as it becomes
convenient.

Pull Xen fixes from Konrad Rzeszutek Wilk:
"This has four bug-fixes and one tiny feature that I forgot to put
initially in my tree due to oversight.
The feature is for kdump kernels to speed up the /proc/vmcore reading.
There is a ram_is_pfn helper function that the different platforms can
register for. We are now doing that.
The bug-fixes cover some embarrassing struct pv_cpu_ops variables
being set to NULL on Xen (but not baremetal). We had a similar issue
in the past with {write|read}_msr_safe and this fills the three
missing ones. The other bug-fix is to make the console output (hvc)
be capable of dealing with misbehaving backends and not fall flat on
its face. Lastly, a quirk for older XenBus implementations that came
with an ancient v3.4 hypervisor (so RHEL5 based) - reading of certain
non-existent attributes just hangs the guest during bootup - so we
take precaution of not doing that on such older installations.
Feature:
- Register a pfn_is_ram helper to speed up reading of /proc/vmcore.
Bug-fixes:

The commit 254d1a3f02, titled
"xen/pv-on-hvm kexec: shutdown watches from old kernel" assumes that the
XenBus backend can deal with reading of values from:
"control/platform-feature-xs_reset_watches":
... a patch for xenstored is required so that it
accepts the XS_RESET_WATCHES request from a client (see changeset
23839:42a45baf037d in xen-unstable.hg). Without the patch for xenstored
the registration of watches will fail and some features of a PVonHVM
guest are not available. The guest is still able to boot, but repeated
kexec boots will fail."
Sadly this is not true when using a Xen 3.4 hypervisor and booting a PVHVM
guest. We end up hanging at:
err = xenbus_scanf(XBT_NIL, "control",
"platform-feature-xs_reset_watches", "%d", &supported);
This can easily be seen with guests hanging at xenbus_init:
NX (Execute Disable) protection: active
SMBIOS 2.4 present.
DMI: Xen HVM domU, BIOS 3.4.0 05/13/2011
Hypervisor detected: Xen HVM
Xen version 3.4.
Xen Platform PCI: I/O protocol version 1
... snip ..
calling xenbus_init+0x0/0x27e @ 1
Reverting the commit or using the attached patch fixes the issue. This fix
checks whether the hypervisor is older than 4.0 and if so does not try to
perform the read.

First, it's incorrect to call putname() after __getname_gfp() since the
bare __getname_gfp() call skips the auditing code, while putname()
doesn't.
mount_block_root allocates a PATH_MAX buffer via __getname_gfp, and then
calls get_fs_names to fill the buffer. That function can call
get_filesystem_list which assumes that that buffer is a full page in
size. On arches where PAGE_SIZE != 4k, then this could potentially
overrun.
In practice, it's hard to imagine the list of filesystem names even
approaching 4k, but it's best to be safe. Just allocate a page for this
purpose instead.
With this, we can also remove the __getname_gfp() definition since there
are no more callers.

In order to accomodate retrying path-based syscalls, we need to add a
new "type" argument to audit_inode_child. This will tell us whether
we're looking for a child entry that represents a create or a delete.

new entry. Instead, use the information we have to try to find an

Currently, this gets set mostly by happenstance when we call into
audit_inode_child. While that might be a little more efficient, it seems
wrong. If the syscall ends up failing before audit_inode_child ever gets
called, then you'll have an audit_names record that shows the full path
but has the parent inode info attached.
Fix this by passing in a parent flag when we call audit_inode that gets
set to the value of LOOKUP_PARENT. We can then fix up the pathname for
the audit entry correctly from the get-go.
While we're at it, clean up the no-op macro for audit_inode in the
!CONFIG_AUDITSYSCALL case.

Most of the callers get called with an inode and dentry in the reverse

2) As promised, I reviewed the pending VB2 DMABUF series.
While setting a test environment, it was noticed that the upstream
support for Samsung Exynos 4 boards (smdk310 and Origen) are
broken upstream, likely due to regressions: both defconfigs are
wrong and regulator settings for both boards are broken. That,
allied with some bug at the dummy regulator driver, causes OOPSes
during boot time.
Long story short: even fixing the above, the proposed patches
OOPSed when running the DMABUF test. Not sure yet if the OOPSes
are due to some other undetected regressions, or due to some bug
on the patches.
Due to the above, DMABUF patches for vb2 got NACKed for 3.7."

tested at the first pull request.
The main reason to not hold off is that the modifications to
irq_domain_add_simple() as reviewed by Rob Herring introduce new
infrastructure for irqdomains that will be useful for the next cycle:
instead of sprinkling irq descriptor allocation all over the kernel
wherever a "legacy" domain is registered, which is necessary for any
platform using sparse IRQs, and many irq chips are say GPIO
controllers which may be used with several systems, some with sparse
IRQs some not, we push this into the irq_domain_add_simple() so we can
atleast do mistakes in one place.
The irq_domain_add_simple() is currently unused in the kernel, so I
need to provide a user. The Nomadik stuff that goes with are changes
to the driver I use day-to-day to make use of this facility (and a
dependency), so see it as a way to eat my own dogfood: if this blows
up the egg hits my face.
A second round of pinctrl patches for v3.7:
- Complement the Nomadik pinctrl driver with alternate Cx functions
so it handles all oddities.
- A patch to the IRQdomain to reform the simple irqdomain to handle
IRQ descriptor allocation dynamically.
- Use the above feature in the Nomadik pin controller."

pinctrl/nomadik: use simple or linear IRQ domain
irqdomain: augment add_simple() to allocate descs

Pull second set of ARM updates from Russell King:
"This is the second set of ARM updates for this merge window.
Contained within are changes to allow the kernel to boot in hypervisor
mode on CPUs supporting virtualization, and cache flushing support to
the point of inner sharable unification, which are used by the
suspend/resume code to avoid having to do a full cache flush.
Also included is one fix for VFP code identified by Michael Olbrich."

Pull writeback fixes from Fengguang Wu:
"Three trivial writeback fixes"
* 'writeback-for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wfg/linux:
CPU hotplug, writeback: Don't call writeback_set_ratelimit() too often during hotplug
writeback: correct comment for move_expired_inodes()
backing-dev: use kstrto* in preference to simple_strtoul
Most of them never returned anyway - only two functions had to be
changed. That allows to simplify their callers a whole lot.
Note that this does *not* apply to kthread_run() callbacks - all of
those had been called from the same kernel_thread() callback, which
did do_exit() already. This is strictly about very few low-level
kernel_thread() callbacks (there are only 6 of those, mostly as part
of kthread.h and kmod.h exported mechanisms, plus kernel_init()
itself).
