====================
pull-request: can 2014-07-25
this is a pull request of one patch for the net tree, hoping to get into the
3.16 release.
The patch by George Cherian fixes a regression in the c_can platform driver.
When using two interfaces the regression leads to a non function second
interface.

This moves the espfix64 logic into native_iret. To make this work,
it gets rid of the native patch for INTERRUPT_RETURN:
INTERRUPT_RETURN on native kernels is now 'jmp native_iret'.
This changes the 16-bit SS behavior on Xen from OOPSing to leaking
some bits of the Xen hypervisor's RSP (I think).
[ hpa: this is a nonzero cost on native, but probably not enough to
measure. Xen needs to fix this in their own code, probably doing
something equivalent to espfix64. ]

cryptsetup fails on arm64 when using kernel encryption via AF_ALG socket.
See https://bugzilla.redhat.com/show_bug.cgi?id=1122937
The bug is caused by incorrect handling of unaligned data in
arch/arm64/crypto/aes-glue.c. Cryptsetup creates a buffer that is aligned
on 8 bytes, but not on 16 bytes. It opens AF_ALG socket and uses the
socket to encrypt data in the buffer. The arm64 crypto accelerator causes
data corruption or crashes in the scatterwalk_pagedone.
This patch fixes the bug by passing the residue bytes that were not
processed as the last parameter to blkcipher_walk_done.

The function rtas_flash_firmware passes the address of a data structure,
flash_block_list, when making the update-flash-64-and-reboot rtas call.
While the endianness of the address is handled correctly, the endianness
of the data is not. This patch ensures that the data in flash_block_list
is big endian when passed to rtas on little endian hosts.

We can continue to read the error log (up to MAX size) even if

Michel Dänzer and a couple of other people reported inexplicable random
oopses in the scheduler, and the cause turns out to be gcc mis-compiling
the load_balance() function when debugging is enabled. The gcc bug
apparently goes back to gcc-4.5, but slight optimization changes means
that it now showed up as a problem in 4.9.0 and 4.9.1.
The instruction scheduling problem causes gcc to schedule a spill
operation to before the stack frame has been created, which in turn can
corrupt the spilled value if an interrupt comes in. There may be other
effects of this bug too, but that's the code generation problem seen in
Michel's case.
This is fixed in current gcc HEAD, but the workaround as suggested by
Markus Trippelsdorf is pretty simple: use -fno-var-tracking-assignments
when compiling the kernel, which disables the gcc code that causes the
problem. This can result in slightly worse debug information for
variable accesses, but that is infinitely preferable to actual code
generation problems.
Doing this unconditionally (not just for CONFIG_DEBUG_INFO) also allows
non-debug builds to verify that the debug build would be identical: we
can do
export GCC_COMPARE_DEBUG=1
to make gcc internally verify that the result of the build is
independent of the "-g" flag (it will make the compiler build everything
twice, toggling the debug flag, and compare the results).
Without the "-fno-var-tracking-assignments" option, the build would fail
(even with 4.8.3 that didn't show the actual stack frame bug) with a gcc
compare failure.

etc.
970 if (WARN_ON_ONCE((current->flags & (PF_MEMALLOC|PF_KSWAPD)) ==
971 PF_MEMALLOC))
I did not respond at the time, because a glance at the PageDirty block
in shrink_page_list() quickly shows that this is impossible: we don't do
writeback on file pages (other than tmpfs) from direct reclaim nowadays.
Dave was hallucinating, but it would have been disrespectful to say so.
However, my own /var/log/messages now shows similar complaints
WARNING: CPU: 1 PID: 28814 at fs/ext4/inode.c:1881 ext4_writepage+0xa7/0x38b()
WARNING: CPU: 0 PID: 27347 at fs/ext4/inode.c:1764 ext4_writepage+0xa7/0x38b()
from stressing some mmotm trees during July.
Could a dirty xfs or ext4 file page somehow get marked PageSwapBacked,
so fail shrink_page_list()'s page_is_file_cache() test, and so proceed
to mapping->a_ops->writepage()?
Yes, 3.16-rc1's commit 68711a746345 ("mm, migration: add destination
page freeing callback") has provided such a way to compaction: if
migrating a SwapBacked page fails, its newpage may be put back on the
list for later use with PageSwapBacked still set, and nothing will clear
it.
Whether that can do anything worse than issue WARN_ON_ONCEs, and get
some statistics wrong, is unclear: easier to fix than to think through
the consequences.
Fixing it here, before the put_new_page(), addresses the bug directly,
but is probably the worst place to fix it. Page migration is doing too
many parts of the job on too many levels: fixing it in
move_to_new_page() to complement its SetPageSwapBacked would be
preferable, except why is it (and newpage->mapping and newpage->index)
done there, rather than down in migrate_page_move_mapping(), once we are
sure of success? Not a cleanup to get into right now, especially not
with memcg cleanups coming in 3.17.

"I have two fixes: one for tracing that fixes a long-standing NULL
pointer dereference, and one for a mac80211 issue that causes iwlmvm to
send invalid frames during authentication/association."
and,
"One more fix - for a bug in the newly introduced code that obtains rate
control information for stations."
For the iwlwifi fixes, Emmanuel says:
"It includes a merge damage fix. This region has been changed in -next
and -fixes quite a few times and apparently, I failed to handle it
properly, so here the fix. Along with that I have a fix from Eliad
to properly handle overlapping BSS in AP mode."
On top of that, Felix provides and ath9k fix for Tx stalls that happen
after an aggregation session failure.
Please let me know if there are problems! There are some changes
here that will cause merge conflicts in -next. Once you merge this
I can pull it into wireless-next and resolve those issues.

net: phy: Prevent an MDIO bus from being unloaded while in use
Changes from v1:
* Dropped the unneeded module_put() on phy_attach_direct().
The motivation of this small series is to fix the current lack of relationship
between an ethernet driver and the MDIO bus behind the PHY device. In such
cases, we would find no visible link between the drivers:
$ lsmod
Module Size Used by Not tainted
mvmdio 2941 0
mvneta 22069 0
Which means nothing prevents the MDIO driver from being removed:
$ modprobe -r mvmdio
# Unable to handle kernel NULL pointer dereference at virtual address 00000060
pgd = c0004000
[00000060] *pgd=00000000

[snip]
This patchset fixes this problem by adding a pair of module_{get,put},
so the module reference count is increased when the PHY device is attached
and is decreased when the PHY is detached.
Tested with mvneta and mv643xx_eth drivers, which depend on the mvmdio
driver to handle MDIO. This series applies on both net and net-next branches.

This commit adds proper module_{get,put} to prevent the MDIO bus module
from being unloaded while the phydev is connected. By doing so, we fix
a kernel panic produced when a MDIO driver is removed, but the phydev
that relies on it is attached and running.

mdiobus_register() registers a device which is already bound to a driver.
Hence, the driver pointer should be set properly in order to track down
the driver associated to the MDIO bus.
This will be used to allow ethernet driver to pin down a MDIO bus driver,
preventing it from being unloaded while the PHY device is running.

Promote one fix for 3.16
This fix was necessary after
9c15a24b038f ("x86/mce: Improve mcheck_init_device() error handling")
went in. What this patch did was, among others, check the return value
of misc_register and exit early if it encountered an error. Original
code sloppily didn't do that.
However,
cef12ee52b05 ("xen/mce: Add mcelog support for Xen platform")
made it so that xen's init routine xen_late_init_mcelog runs first. This
was needed for the xen mcelog device which is supposed to be independent
from the baremetal one.
Initially it was reported that misc_register() fails often on xen and
that's why it needed fixing. However, it is *supposed* to fail by
design, when running in dom0 so that the xen mcelog device file gets
registered first.
And *then* you need the notifier *not* unregistered on the error path so
that the timer does get deleted properly in the CPU hotplug notifier.
Btw, this fix is needed also on baremetal in the unlikely event that
misc_register(&mce_chrdev_device) fails there too.
I was unsure whether to rush it in now and decided to delay it to 3.17.
However, xen people wanted it promoted as it breaks xen when doing cpu
hotplug there. So, after a bit of simmering in tip/master for initial
smoke testing, let's move it to 3.16. It fixes a semi-regression which
got introduced in 3.16 so no need for stable tagging.
tip/x86/ras contains that exact same commit but we can't remove it
there as it is not the last one. It won't cause any merge issues, as I
confirmed locally but I should state here the special situation of this
one fix explicitly anyway.
Thanks.

This time in time! Just 32bit-pae fix from Hugh, semaphores fun from Chris
and a fix for runtime pm cherry-picked from next.
Paulo is still working on a fix for runtime pm when X does cursor fun when
the display is off, but that one isn't ready yet.

alloc_bootmem and related function always return zeroed region of
memory. Thus a memset after calls to these functions is unnecessary.
The following Coccinelle semantic patch was used for making the change:
@@
expression E,E1;
@@
E = \(alloc_bootmem\|alloc_bootmem_low\|alloc_bootmem_pages\|alloc_bootmem_low_pages\)(...)
... when != E
- memset(E,0,E1);

present if SA_RESTORER is defined. So, the define needs to be removed.

Temperature limit clamps are applied after converting the temperature
from milli-degrees C to degrees C, so either the clamp limit needs
to be specified in degrees C, not milli-degrees C, or clamping must
happen before converting to degrees C. Use the latter method to avoid
overflows.
vrm is an u8, so the written value needs to be limited to [0, 255].
