Commit 82c02f58ba3a ("usb: musb: Allow multiple glue layers to be
built in") enabled selecting multiple glue layers, which in turn
exposed things more for randconfig builds. If NOP_USB_XCEIV is
built-in and TUSB6010 is a loadable module, we will get:
drivers/built-in.o: In function `tusb_remove':
tusb6010.c:(.text+0x16a817): undefined reference to `usb_phy_generic_unregister'
drivers/built-in.o: In function `tusb_probe':
tusb6010.c:(.text+0x16b24e): undefined reference to `usb_phy_generic_register'
make: *** [vmlinux] Error 1
Let's fix this the same way as commit 70c1ff4b3c86 ("usb: musb:
tusb-dma can't be built-in if tusb is not").
And while at it, let's not allow selecting the glue layers except
on platforms really using them unless COMPILE_TEST is specified:
- TUSB6010 is in practise only used on omaps
- DSPS is only used on TI platforms
- UX500 is only used on STE platforms

At f_audio_free_inst, it tries to access struct gaudio *card which is
freed at f_audio_free, it causes below oops if the audio device is not
there (do unload module may trigger the same problem). The gaudio_cleanup
is related to function, so it is better move to f_audio_free.

!strncmp(buf, "force host", 9) is true if and only if buf starts with
"force hos". This was obviously not what was intended. The same error
exists for "force full-speed", "force high-speed" and "test
packet". Using strstarts avoids the error-prone hardcoding of the
prefix length.
For consistency, also change the other occurences of the !strncmp
idiom.

Blackfin's MUSB implementation lacks a bunch of

Blackfin builds.

If a request is backlogged, it's complete() handler will get called
twice: once with -EINPROGRESS, and once with the final error code.
af_alg's complete handler, unlike other users, does not handle the
-EINPROGRESS but instead always completes the completion that recvmsg()
is waiting on. This can lead to a return to user space while the
request is still pending in the driver. If userspace closes the sockets
before the requests are handled by the driver, this will lead to
use-after-frees (and potential crashes) in the kernel due to the tfm
having been freed.
The crashes can be easily reproduced (for example) by reducing the max
queue length in cryptod.c and running the following (from
http://www.chronox.de/libkcapi.html) on AES-NI capable hardware:
$ while true; do kcapi -x 1 -e -c '__ecb-aes-aesni' \
-k 00000000000000000000000000000000 \
-p 00000000000000000000000000000000 >/dev/null & done

The previous cleanup of BMC attributes left a few holes, and if
you run with lockdep debugging with a BMC with the proper attributes,
you could get a warning.
This patch removes all the unused attributes from the BMC structure,
since they are all declared in the .data section now. It makes
the attributes all static. It fixes the referencing of the
attributes in a couple of cases that dynamically added the files
depending on BMC information.

Check that length specified in a component of a symlink fits in the
input buffer we are reading. Also properly ignore component length for
component types that do not use it. Otherwise we read memory after end
of buffer for corrupted udf image.

It seems that ever since (536f6b9 mmc: dw_mmc: Reset DMA before
enabling IDMAC) landed upstream that SD cards have been very unhappy
on rk3288-evb. They were a little unhappy before that change, but
after that change they're REALLY unhappy.
It turns out that the above fix happens to fix a corruption when
reading card information during probe time. Without the fix we didn't
detect that high speed SD cards could actually support high speed.
With the fix we suddenly detect that they're high speed and we try to
use them at 50MHz. That doesn't work so well on EVB with the default
drive strength (maybe because there are two physical SD card slots
hooked up to the same pin?).
Fix the problem by bumping up the drive strength of the sdmmc lines.

When amdkfd and radeon are compiled inside the kernel image (not as modules),
radeon will load before amdkfd, which will cause a bug when radeon will probe
the GPUs.
When the two drivers are compiled as modules, amdkfd is loaded after radeon is
loaded but before radeon starts probing the GPUs. This is done because radeon
loads the amdkfd module through symbol_request function.
This patch makes amdkfd load before radeon when they are both compiled inside
the kernel image, which makes the behavior similar to the case when they are
modules, and prevents the kernel bug.

AMD GPU devices are dependent on AMD IOMMU controller functionality to allow
the GPU to access a process's virtual memory address space, without the need
for pinning the memory.
This patch changes the order in the drivers makefile, so iommu/ subsystem is
linked before gpu/ subsystem. That way, if the gpu and iommu drivers are
compiled inside the kernel image (not as modules), the correct order of device
loading is still maintained (iommu module is loaded before gpu module).

The commit b4607572ef86 (ARM: mvebu: remove conflicting muxing on
Armada 370 DB) removes the hog pins muxing. As it is explained in the
commit log it solves a warning a boot time, but more important it also
allows using the Giga port 0 of the board.
Unfortunately in the same time the commit 4904a82a9399 (arm: mvebu:
move Armada 370/XP pinctrl node definition armada-370-xp.dtsi) was
merged and it introduced again the hog pins muxing. Because of it, the
Giga port 0 of the board is no more usable.
This commit remove again the conflicting muxing (hopefully for the

Pull a VDSO fix from Andy Lutomirski:
"One vdso fix for a longstanding ASLR bug that's been in the news lately.
The vdso base address has always been randomized, and I don't think there's
anything particularly wrong with the range over which it's randomized,
but the implementation seems to have been buggy since the very beginning.
This fixes the implementation to remove a large bias that caused a small
fraction of possible vdso load addresess to be vastly more likely than
the rest of the possible addresses."

The theory behind vdso randomization is that it's mapped at a random
offset above the top of the stack. To avoid wasting a page of
memory for an extra page table, the vdso isn't supposed to extend
past the lowest PMD into which it can fit. Other than that, the
address should be a uniformly distributed address that meets all of
the alignment requirements.
The current algorithm is buggy: the vdso has about a 50% probability
of being at the very end of a PMD. The current algorithm also has a
decent chance of failing outright due to incorrect handling of the
case where the top of the stack is near the top of its PMD.
This fixes the implementation. The paxtest estimate of vdso
"randomisation" improves from 11 bits to 18 bits. (Disclaimer: I
don't know what the paxtest code is actually calculating.)
It's worth noting that this algorithm is inherently biased: the vdso
is more likely to end up near the end of its PMD than near the
beginning. Ideally we would either nix the PMD sharing requirement
or jointly randomize the vdso and the stack to reduce the bias.
In the mean time, this is a considerable improvement with basically
no risk of compatibility issues, since the allowed outputs of the
algorithm are unchanged.
As an easy test, doing this:
for i in `seq 10000`
do grep -P vdso /proc/self/maps |cut -d- -f1
done |sort |uniq -d
used to produce lots of output (1445 lines on my most recent run).
A tiny subset looks like this:
7fffdfffe000
7fffe01fe000
7fffe05fe000
7fffe07fe000
7fffe09fe000
7fffe0bfe000
7fffe0dfe000
Note the suspicious fe000 endings. With the fix, I get a much more
palatable 76 repeated addresses.

Pull ACCESS_ONCE cleanup preparation from Christian Borntraeger:
"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.
