From: Anton Blanchard <[email protected]>
commit 73d2fb758e678c93bc76d40876c2359f0729b0ef upstream.
POWER8 allows read and write of the DSCR in userspace. We added
kernel emulation so applications could always use the instructions
regardless of the CPU type.
Unfortunately there are two SPRs for the DSCR and we only added
emulation for the privileged one. Add code to match the non
privileged one.
A simple test was created to verify the fix:
http://ozlabs.org/~anton/junkcode/user_dscr_test.c
Without the patch we get a SIGILL and it passes with the patch.

commit f7a1dd6e3ad59f0cfd51da29dfdbfd54122c5916 upstream.

matchoff and matchlen.

------------------
From: "Steven Rostedt (Red Hat)" <[email protected]>
commit 7fe70b579c9e3daba71635e31b6189394e7b79d3 upstream.
ftrace_dump() had a lot of issues. What ftrace_dump() does, is when
ftrace_dump_on_oops is set (via a kernel parameter or sysctl), it
will dump out the ftrace buffers to the console when either a oops,
panic, or a sysrq-z occurs.
This was written a long time ago when ftrace was fragile to recursion.
But it wasn't written well even for that.
There's a possible deadlock that can occur if a ftrace_dump() is happening
and an NMI triggers another dump. This is because it grabs a lock
before checking if the dump ran.
It also totally disables ftrace, and tracing for no good reasons.
As the ring_buffer now checks if it is read via a oops or NMI, where
there's a chance that the buffer gets corrupted, it will disable
itself. No need to have ftrace_dump() do the same.
ftrace_dump() is now cleaned up where it uses an atomic counter to
make sure only one dump happens at a time. A simple atomic_inc_return()
is enough that is needed for both other CPUs and NMIs. No need for
a spinlock, as if one CPU is running the dump, no other CPU needs
to do it too.
The tracing_on variable is turned off and not turned on. The original
code did this, but it wasn't pretty. By just disabling this variable
we get the result of not seeing traces that happen between crashes.
For sysrq-z, it doesn't get turned on, but the user can always write
a '1' to the tracing_on file. If they are using sysrq-z, then they should
know about tracing_on.
The new code is much easier to read and less error prone. No more
deadlock possibility when an NMI triggers here.

From: Jerry Hoemann <[email protected]>
Patch for -stable. Function find_early_table_space removed upstream.
Fixes panic in alloc_low_page due to pgt_buf overflow during
init_memory_mapping.
find_early_table_space sizes pgt_buf based upon the size of the
memory being mapped, but it does not take into account the alignment
of the memory. When the region being mapped spans a 512GB (PGDIR_SIZE)
alignment, a panic from alloc_low_pages occurs.
kernel_physical_mapping_init takes into account PGDIR_SIZE alignment.
This causes an extra call to alloc_low_page to be made. This extra call
isn't accounted for by find_early_table_space and causes a kernel panic.
Change is to take into account PGDIR_SIZE alignment in find_early_table_space.

commit e4bfff54ed3f5de88f5358504c78c2cb037813aa upstream.
As discussed in this thread
http://lists.freedesktop.org/archives/dri-devel/2013-April/037411.html
GMBUS based DVO transmitter detection seems to be unreliable which could
result in an unusable DVO port.
The attached patch fixes this by falling back to bit banging mode for
the time DVO transmitter detection is in progress.

This is only solution I can think of. User decides if he wants this
driver on his machine. I don't have enough knowledge and time to find
the reason why same code works on some machines and doesn't on others
which use the same, or very similar, chipset and processor.

commit a83d6755814e4614ba77e15d82796af0f695c6b8 upstream.
When a device attached to the roothub is suspended, the endpoint rings
are stopped. The host may generate a completion event with the
completion code set to 'Stopped' or 'Stopped Invalid' when the ring is
halted. The current xHCI code prints a warning in that case, which can
be really annoying if the USB device is coming into and out of suspend.
Remove the unnecessary warning.

The LBR 'from' adddress is under full userspace control; ensure
we validate it before reading from it.
Note: is_module_text_address() can potentially be quite
expensive; for those running into that with high overhead
in modules optimize it using an RCU backed rb-tree.

commit 13f85203e1060da83d9ec1c1c5a63343eaab8de4 upstream.
Some ancient pHyp versions used to create a 8 bytes local-mac-address
property in the device-tree instead of a 6 bytes one for veth.
The Linux driver code to deal with that is an insane hack which also
happens to break with some choices of MAC addresses in qemu by testing
for a bit in the address rather than just looking at the size of the
property.
Sanitize this by doing the latter instead.

From: David Jeffery <[email protected]>
commit ce8a5dbdf9e709bdaf4618d7ef8cceb91e8adc69 upstream.
When checking if an autofs mount point is busy it isn't sufficient to
only check if it's a mount point.
For example, if the mount of an offset mountpoint in a tree is denied
for this host by its export and the dentry becomes a process working
directory the check incorrectly returns the mount as not in use at
expire.
This can happen since the default when mounting within a tree is
nostrict, which means ingnore mount fails on mounts within the tree and
continue. The nostrict option is meant to allow mounting in this case.

commit 7122beeee7bc1757682049780179d7c216dd1c83 upstream.
The following commit breaks numa distance setup for old powerpc
systems that use form0 encoding in device tree.
commit 41eab6f88f24124df89e38067b3766b7bef06ddb
powerpc/numa: Use form 1 affinity to setup node distance
Device tree node /rtas/ibm,associativity-reference-points would
index into /cpus/PowerPCxxxx/ibm,associativity based on form0 or
form1 encoding detected by ibm,architecture-vec-5 property.
All modern systems use form1 and current kernel code is correct.
However, on older systems with form0 encoding, the numa distance
will get hard coded as LOCAL_DISTANCE for all nodes. This causes
task scheduling anomaly since scheduler will skip building numa
level domain (topmost domain with all cpus) if all numa distances
are same. (value of 'level' in sched_init_numa() will remain 0)
Prior to the above commit:
((from) == (to) ? LOCAL_DISTANCE : REMOTE_DISTANCE)
Restoring compatible behavior with this patch for old powerpc systems
with device tree where numa distance are encoded as form0.

This kernel can be built and boot without any problem.
Building a kernel with this kernel also works fine.
- Build Machine: debian wheezy x86_64
CPU: Intel(R) Core(TM) i5-2400 CPU @ 3.10GHz x 4
memory: 8GB
- Test machine: debian wheezy x86_64(KVM guest on the Build Machine)
vCPU: x2
memory: 2GB
I reviewed the following patch and it looks good to me.
