It also adds logic in core_scsi3_update_and_write_aptpl() to double

vhost/scsi: potential memory corruption
This code in vhost_scsi_make_tpg() is confusing because we limit "tpgt"

I looked at the context and it turns out that in
vhost_scsi_set_endpoint(), "tpg->tport_tpgt" is used as an offset into
the vs_tpg[] array which has VHOST_SCSI_MAX_TARGET (256) elements so
anything higher than 255 then it is invalid. I have made that the limit
now.

WQ_UNBOUND will allow bouncing to another CPU if the running

and will first try to bounce within the same NUMA socket.
My measurements with NULL backend devices show that there is
no (noticeable) additional latency as a result of the change.
I'd expect even to gain performance when working with fast

"kernel: Provide READ_ONCE and ASSIGN_ONCE
As discussed on LKML http://marc.info/?i=
54611D86.
4040306%40de.ibm.com
ACCESS_ONCE might fail with specific compilers for non-scalar
accesses.
Here is a set of patches to tackle that problem.
The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data
structure is larger than the machine word size memcpy is used and a
warning is emitted. The next patches fix up several in-tree users of
ACCESS_ONCE on non-scalar types.
This does not yet contain a patch that forces ACCESS_ONCE to work only
on scalar types. This is targetted for the next merge window as Linux
next already contains new offenders regarding ACCESS_ONCE vs.

Unfortunaly one of the real problematic commits was right at the
beginning, so I rebased this portion of the pending patches without
the offenders.
It would be great to get this into 3.19. That makes reworking the
problematic parts simpler. The usual tip testing did not unearth any
issues and it is fully bisectible now.
I'm pretty confident that this wont affect the calmness of the xmas
season.
Changes:
- Split the convoluted io_apic.c code into domain specific parts
(vector, ioapic, msi, htirq)
- Introduce proper helper functions to retrieve irq specific data
instead of open coded dereferencing of pointers
- Preparatory work for ioapic hotplug and irqdomain conversion
- Removal of the non functional pci-ioapic driver
- Removal of unused irq entry stubs
- Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC
allocations for everything which is called from there.
- Small cleanups and fixes"

tick/powerclamp: Remove tick_nohz_idle abuse
commit
4dbd27711cd9 "tick: export nohz tick idle symbols for module
use" was merged via the thermal tree without an explicit ack from the
relevant maintainers.
The exports are abused by the intel powerclamp driver which implements
a fake idle state from a sched FIFO task. This causes all kinds of
wreckage in the NOHZ core code which rightfully assumes that
tick_nohz_idle_enter/exit() are only called from the idle task itself.
Recent changes in the NOHZ core lead to a failure of the powerclamp
driver and now people try to hack completely broken and backwards
workarounds into the NOHZ core code. This is completely unacceptable
and just papers over the real problem. There are way more subtle
issues lurking around the corner.
The real solution is to fix the powerclamp driver by rewriting it with
a sane concept, but that's beyond the scope of this.
So the only solution for now is to remove the calls into the core NOHZ
code from the powerclamp trainwreck along with the exports.

- Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the

- Make the ACPI EC driver more robust against race conditions related
to GPE handler installation failures (Lv Zheng).
- Prevent the ACPI device PM core code from attempting to disable
GPEs that it has not enabled which confuses ACPICA and makes it
report errors unnecessarily (Rafael J Wysocki).
- Add a "force" command line switch to the intel_pstate driver to
make it possible to override the blacklisting of some systems in
that driver if needed (Ethan Zhao).
- Improve intel_pstate code documentation and add a MAINTAINERS entry

- Make the ACPI fan driver create cooling device interfaces witn
names that reflect the IDs of the ACPI device objects they are

mm/zsmalloc: adjust order of functions
Currently functions in zsmalloc.c does not arranged in a readable and
reasonable sequence. With the more and more functions added, we may
meet below inconvenience. For example:
Current functions:
void zs_init()
{
}
static void get_maxobj_per_zspage()
{
}
Then I want to add a func_1() which is called from zs_init(), and this
new added function func_1() will used get_maxobj_per_zspage() which is
defined below zs_init().
void func_1()
{
get_maxobj_per_zspage()
}
void zs_init()
{
func_1()
}
static void get_maxobj_per_zspage()
{
}
This will cause compiling issue. So we must add a declaration:
static void get_maxobj_per_zspage();
before func_1() if we do not put get_maxobj_per_zspage() before
func_1().
In addition, puting module_[init|exit] functions at the bottom of the
file conforms to our habit.
So, this patch ajusts function sequence as:
/* helper functions */
...
obj_location_to_handle()
...
/* Some exported functions */
...
zs_map_object()
zs_unmap_object()
zs_malloc()
zs_free()
zs_init()
zs_exit()

ocfs2: fix journal commit deadlock
For buffer write, page lock will be got in write_begin and released in
write_end, in ocfs2_write_end_nolock(), before it unlock the page in
ocfs2_free_write_ctxt(), it calls ocfs2_run_deallocs(), this will ask
for the read lock of journal->j_trans_barrier. Holding page lock and
ask for journal->j_trans_barrier breaks the locking order.
This will cause a deadlock with journal commit threads, ocfs2cmt will
get write lock of journal->j_trans_barrier first, then it wakes up
kjournald2 to do the commit work, at last it waits until done. To
commit journal, kjournald2 needs flushing data first, it needs get the
cache page lock.
Since some ocfs2 cluster locks are holding by write process, this
deadlock may hung the whole cluster.
unlock pages before ocfs2_run_deallocs() can fix the locking order, also
put unlock before ocfs2_commit_trans() to make page lock is unlocked
before j_trans_barrier to preserve unlocking order.

ocfs2: reflink: fix slow unlink for refcounted file
When running ocfs2 test suite multiple nodes reflink stress test, for a
4 nodes cluster, every unlink() for refcounted file needs about 700s.
The slow unlink is caused by the contention of refcount tree lock since
all nodes are unlink files using the same refcount tree. When the
unlinking file have many extents(over 1600 in our test), most of the
extents has refcounted flag set. In ocfs2_commit_truncate(), it will
execute the following call trace for every extents. This means it needs
get and released refcount tree lock about 1600 times. And when several
nodes are do this at the same time, the performance will be very low.
ocfs2_remove_btree_range()
-- ocfs2_lock_refcount_tree()
---- ocfs2_refcount_lock()
------ __ocfs2_cluster_lock()
ocfs2_refcount_lock() is costly, move it to ocfs2_commit_truncate() to
do lock/unlock once can improve a lot performance.

When the system boots up, in the dmesg logs we can see the memory
statistics along with total reserved as below. Memory: 458840k/458840k

When CMA is enabled, still the total reserved memory remains the same.
However, the CMA memory is not considered as reserved. But, when we see
/proc/meminfo, the CMA memory is part of free memory. This creates
confusion. This patch corrects the problem by properly subtracting the
CMA reserved memory from the total reserved memory in dmesg logs.

hfsplus: fix longname handling
Longname is not correctly handled by hfsplus driver. If an attempt to
create a longname(>255) file/directory is made, it succeeds by creating a
file/directory with HFSPLUS_MAX_STRLEN and incorrect catalog key. Thus
leaving the volume in an inconsistent state. This patch fixes this issue.
Although lookup is always called first to create a negative entry, so just
doing a check in lookup would probably fix this issue. I choose to
propagate error to other iops as well.

Merge tag 'for-linus' of git://git./virt/kvm/kvm
Pull KVM update from Paolo Bonzini:
"3.19 changes for KVM:
- spring cleaning: removed support for IA64, and for hardware-
assisted virtualization on the PPC970
- ARM, PPC, s390 all had only small fixes
For x86:
- small performance improvements (though only on weird guests)
- usual round of hardware-compliancy fixes from Nadav
- APICv fixes
- XSAVES support for hosts and guests. XSAVES hosts were broken
because the (non-KVM) XSAVES patches inadvertently changed the KVM
userspace ABI whenever XSAVES was enabled; hence, this part is
going to stable. Guest support is just a matter of exposing the
feature and CPUID leaves support"
