[PATCH 05/94] clk: ti: set CLK_SET_RATE_NO_REPARENT for ti,mux-clock
From: Tomi Valkeinen
When setting the rate of a clock, by default the clock framework will
change the parent of the clock to the most suitable one in
__clk_mux_determine_rate() (most suitable by looking at the clock rate).
This is a rather dangerous default, and causes problems on AM43x when
using display and ethernet. There are multiple ways to select the clock
muxes on AM43x, and some of those clock paths have the same source
clocks for display and ethernet. When changing the clock rate for the
display subsystem, the clock framework decides to change the display mux
from the dedicated display PLL to a shared PLL which is used by the
ethernet, and then changes the rate of the shared PLL, breaking the
ethernet.
As I don't think there ever is a case where we want the clock framework
to automatically change the parent clock of a clock mux, this patch sets
the CLK_SET_RATE_NO_REPARENT for all ti,mux-clocks.

[PATCH 12/94] dma: cppi41: handle 0-length packets
From: Daniel Mack
When a 0-length packet is received on the bus, desc->pd0 yields 1,
which confuses the driver's users. This information is clearly wrong
and not in accordance to the datasheet, but it's been observed on an
AM335x board, very reproducible.
Fix this by looking at bit 19 in PD2 of the completed packet. This bit
will tell us if a zero-length packet was received on a queue. If it's
set, ignore the value in PD0 and report a total length of 0 instead.

[PATCH 09/94] clk: s3c64xx: Hookup SPI clocks correctly
From: Charles Keepax
In the move to this clock driver the hookups for the SPI clocks were
dropped, which causes my system Cragganmore (s3c6410 based) to be unable
to locate any spibus clocks. This patch adds them back in.
When taking the clock from the epll clock (SCLK) the rates on the SPI
bus are incorrect, this needs further debugging but the hookup here
should be correct and the problem should be else where.
The USBCLK case has been dropped because this requires the USB PHY to be
enabled.

[PATCH 11/94] clk: exynos5420: Remove aclk66_peric from the clock tree description
From: Doug Anderson
The "aclk66_peric" clock is a gate clock with a whole bunch of gates
underneath it. This big gate isn't very useful to include in our
clock tree. If any of the children need to be turned on then the big
gate will need to be on anyway. ...and there are plenty of other "big
gates" that aren't described in our clock tree, some of which shut off
collections of clocks that have no relationship in the hierarchy so
are hard to model.
"aclk66_peric" is causing earlyprintk problems since it gets disabled
as part of the boot process, so let's just remove it.
Strangely (and for no good reason) this clock is exported as part of
the common clock bindings. Remove it since there are no in-kernel
device trees using it and no reason anyone out of tree should refer to
it either.

[PATCH 24/94] clocksource: exynos_mct: Register the timer for stable udelay
From: Amit Daniel Kachhap
This patch registers the exynos mct clocksource as the current timer
as it has constant clock rate. This will generate correct udelay for
the exynos platform and avoid using unnecessary calibrated
jiffies. This change has been tested on exynos5420 based board and
udelay is very close to expected.
Without this patch udelay() on exynos5400 / exynos5800 is wildly
inaccurate due to big.LITTLE not adjusting loops_per_jiffy correctly.
Also without this patch udelay() on exynos5250 can be innacruate
during transitions between frequencies < 800 MHz (you'll go 200 MHz ->
800 MHz -> 300 MHz and will run at 800 MHz for a time with the wrong
loops_per_jiffy).

[PATCH 88/94] clk: spear3xx: Set proper clock parent of uart1/2
From: Thomas Gleixner
The uarts only work when the parent is ras_ahb_clk. The stale 3.5
based ST tree does this in the board file.
Add it to the clk init function. Not pretty, but the mess there is
amazing anyway.

[PATCH 81/94] Documenation/laptops: rename and update hpfall.c
From: Pali Rohár
Dell kernel driver dell-smo8800 provides same freefall interface as hp_accel so
program hpfall.c works also on Dell laptops. So rename it to freefall.c.
Dell driver does not provide hp::hddprotect led so make sure that freefall.c
works also if hp::hddprotect does not exist in sysfs.
Additionally write info to syslog.

[PATCH 60/94] ARM: EXYNOS: Add support for clock handling in power domain
From: Prathyush K
While powering on/off a local powerdomain in exynos5 chipsets, the
input clocks to each device gets modified. This behaviour is based
on the SYSCLK_SYS_PWR_REG registers.
E.g. SYSCLK_MFC_SYS_PWR_REG = 0x0, the parent of input clock to MFC
(aclk333) gets modified to oscclk
= 0x1, no change in clocks.
The recommended value of SYSCLK_SYS_PWR_REG before power gating any
domain is 0x0. So we must also restore the clocks while powering on
a domain everytime.
This patch adds the framework for getting the required mux and parent
clocks through a power domain device node. With this patch, while
powering off a domain, parent is set to oscclk and while powering back
on, its re-set to the correct parent which is as per the recommended
pd on/off sequence.

[PATCH 44/94] ARM: OMAP2+: create dsp device only on OMAP3 SoCs
From: Suman Anna
The DSP platform device for TI DSP/Bridge is currently
created unconditionally whenever CONFIG_TIDSPBRIDGE is
enabled. This device should only be created on OMAP34xx/
OMAP36xx SoCs, and not for other OMAP3 derived SoCs or when
booting multi-arch images on other SoCs. So, add a check for
the SoC family both before creating the device and allocating
the carveout memory for the device.

[PATCH 52/94] ARM: imx: fix shared gate clock
From: Shawn Guo
Let's say clock A and B are two gate clocks that share the same register
bit in hardware. Therefore they are registered as shared gate clocks
with imx_clk_gate2_shared().
In a scenario that only clock A is enabled by clk_enable(A) while B is
not used, the shared gate will be unexpectedly disabled in hardware.
It happens because clk_enable(A) increments the share_count from 0 to 1,
while clock B is unused to clock core, and therefore the core function
will just disable B by calling clk->ops->disable() directly. The
consequence of that call is share_count is decremented to 0 and the gate
is disabled in hardware, even though clock A is still in use.
The patch fixes the issue by initializing the share_count per hardware
state and returns enable state per share_count from .is_enabled() hook,
in case it's a shared gate.
While at it, add a check in clk_gate2_disable() to ensure it's never
called with a zero share_count.

bitmap, if the block allocation bitmap is also uninitalized, we need
to get write access to the block group descriptor before we start
modifying the block group descriptor flags and updating the free block
count, etc. Otherwise, there is the potential of a bad journal
checksum (if journal checksums are enabled), and of the file system
becoming inconsistent if we crash at exactly the wrong time.

- Driver: 8255
- Description: generic 8255 support
- Devices: [standard] 8255 (8255)
- Author: ds
- Status: works
- Updated: Fri, 7 Jun 2002 12:56:45 -0700
-
- The classic in digital I/O. The 8255 appears in Comedi as a single
- digital I/O subdevice with 24 channels. The channel 0 corresponds
- to the 8255's port A, bit 0; channel 23 corresponds to port C, bit
- 7. Direction configuration is done in blocks, with channels 0-7,
- 8-15, 16-19, and 20-23 making up the 4 blocks. The only 8255 mode
- supported is mode 0.
-
- You should enable compilation this driver if you plan to use a board
- that has an 8255 chip. For multifunction boards, the main driver will
- configure the 8255 subdevice automatically.
-
- This driver also works independently with ISA and PCI cards that
- directly map the 8255 registers to I/O ports, including cards with
- multiple 8255 chips. To configure the driver for such a card, the
- option list should be a list of the I/O port bases for each of the
- 8255 chips. For example,
-
- comedi_config /dev/comedi0 8255 0x200,0x204,0x208,0x20c
-
- Note that most PCI 8255 boards do NOT work with this driver, and
- need a separate driver as a wrapper. For those that do work, the
- I/O port base address can be found in the output o

From: Geert Uytterhoeven
My enhancement to store the initial mapping size for later reuse in commit
486df8bc4627bdfc032d11bedcd056cc5343ee62 ("m68k: Increase initial mapping
to 8 or 16 MiB if possible") broke booting on machines where RAM doesn't
start at address zero.
Use pc-relative addressing to fix this.

[PATCH 43/94] ARM: dts: dra7-evm: Make VDDA_1V8_PHY supply always on
From: Roger Quadros After clarification from the hardware team it was found that this 1.8V PHY supply can't be switched OFF when SoC is Active. Since the PHY IPs don't contain isolation logic built in the design to allow the power rail to be switched off, there is a very high risk of IP reliability and additional leakage paths which can result in additional power consumption. The only scenario where this rail can be switched off is part of Power on reset sequencing, but it needs to be kept always-on during operation. This patch is required for proper functionality of USB, SATA and PCIe on DRA7-evm.

[PATCH 75/94] phy: omap-usb2: Balance pm_runtime_enable() on probe failure and remove
From: Roger Quadros
If probe fails then we need to call pm_runtime_disable() to balance
out the previous pm_runtime_enable() call. Else it will cause
unbalanced pm_runtime_enable() call in the succeding probe call.
This anomaly was observed when the call to devm_phy_create() failed
with -EPROBE_DEFER.
Balance out the pm_runtime_enable() call in .remove() as well.

[PATCH 67/94] ext4: revert commit which was causing fs corruption after journal replays
From: Theodore Ts'o
Commit 007649375f6af2 ("ext4: initialize multi-block allocator before
checking block descriptors") causes the block group descriptor's count
of the number of free blocks to become inconsistent with the number of
free blocks in the allocation bitmap. This is a harmless form of fs
corruption, but it causes the kernel to potentially remount the file
system read-only, or to panic, depending on the file systems's error
behavior.
Thanks to Eric Whitney for his tireless work to reproduce and to find
the guilty commit.

[PATCH 17/94] ARM: kprobes: Disallow instructions with PC and register specified shift
From: Jon Medhurst
ARM data processing instructions which have a register specified shift
are defined as UNPREDICTABLE if PC is used for any register, not just
the shift value as the code was previous assuming. This issue manifests
on A15 devices as either test case failures or undefined instructions
aborts.

[PATCH 13/94] Update imx-sdma cyclic handling to report residue
From: Russell King - ARM Linux
I received a report this morning from one of the Novena developers that
the behaviour of the iMX6 ASoC codec driver (using imx-pcm-dma.c) was
sub-optimal under high system load.
While there are issues relating to system load remaining, upon reviewing
the ASoC imx-pcm-dma.c driver, it was noticed that it not using the
residue support, because SDMA doesn't support it. This has the effect
that SDMA has to make multiple calls into the ASoC and ALSA code, one
for each period.
Since ALSA's snd_pcm_elapsed() does not need to be called multiple times
and it is entirely sufficient to call it once to update ALSA with the
current buffer position via the pointer method, we can do better here.
We can also avoid stopping the DMA entirely, just like real cyclic DMA
implementations behave. While this means that we replay some old samples,
this is a nicer behaviour than having audio stop and restart.
The changes to achieve this are relatively minor - imx-sdma.c can track
where the DMA is to the nearest descriptor boundary - it does this
already when deciding how many callbacks to issue. In doing this,
buf_tail always points at the descriptor which will complete next.
The residue is defined by the bytes remaining to the end of the buffer,
when the buffer is viewed as a single block of memory [start...end].
So, when we start out, there's a full buffer worth of residue, and this
counts down as we approach the end of the buffer, eventually becoming
zero at the end, before returning to the full buffer worth when we
wrap back to the start.
Moving the walking of the descriptors into the interrupt handler means
that we can update the BD_DONE flag at interrupt time, thus avoiding
a delayed tasklet stopping the cyclic DMA.
This means that the residue can be calculated from (total descriptors -
buf_tail) * descriptor size. This is what the change below does. We
update imx-pcm-dma.c to remove the NO_RESIDUE flag since we now provide
the residue.

[PATCH 14/94] clk: s2mps11: Fix double free corruption during driver unbind
From: Krzysztof Kozlowski
After unbinding the driver memory was corrupted by double free of
clk_lookup structure. This lead to OOPS when re-binding the driver
again.
The driver allocated memory for 'clk_lookup' with devm_kzalloc. During
driver removal this memory was freed twice: once by clkdev_drop() and
second by devm code.

[PATCH 23/94] clocksource: exynos_mct: Fix ftrace
From: Doug Anderson
In (93bfb76 clocksource: exynos_mct: register sched_clock callback) we
supported using the MCT as a scheduler clock. We properly marked
exynos4_read_sched_clock() as notrace. However, we then went and
called another function that _wasn't_ notrace. That means if you do:
cd /sys/kernel/debug/tracing/
echo function_graph > current_tracer
You'll get a crash.
Fix this (but still let other readers of the MCT be trace-enabled) by
adding an extra function. It's important to keep other users of MCT
traceable because the MCT is actually quite slow to access and we want
exynos4_frc_read() to show up in ftrace profiles if it's the
bottleneck.

[PATCH 85/94] parisc: fix fanotify_mark() syscall on 32bit compat kernel
From: Helge Deller
On parisc we can not use the existing compat implementation for fanotify_mark()
because for the 64bit mask parameter the higher and lower 32bits are ordered
differently than what the compat function expects from big endian
architectures.
Specifically:
It finally turned out, that on hppa we end up with different assignments
of parameters to kernel arguments depending on if we call the glibc
wrapper function
int fanotify_mark (int __fanotify_fd, unsigned int __flags,
uint64_t __mask, int __dfd, const char *__pathname);
or directly calling the syscall manually
syscall(__NR_fanotify_mark, ...)
Reason is, that the syscall() function is implemented as C-function and
because we now have the sysno as first parameter in front of the other
parameters the compiler will unexpectedly add an empty paramenter in
front of the u64 value to ensure the correct calling alignment for 64bit
values.
This means, on hppa you can't simply use syscall() to call the kernel
fanotify_mark() function directly, but you have to use the glibc
function instead.
This patch fixes the kernel in the hppa-arch specifc coding to adjust
the parameters in a way as if userspace calls the glibc wrapper function
fanotify_mark().

[PATCH 16/94] ARM: kprobes: Prevent known test failures stopping other tests running
From: Jon Medhurst
Due to a long-standing issue with Thumb symbol lookup [1] the jprobes
tests fail when built into a kernel compiled as Thumb mode. (They work
fine for ARM mode kernels or for Thumb when built as a loadable module.)
Rather than have this problem terminate testing prematurely lets instead
emit an error message and carry on with the main kprobes tests, delaying
the final failure report until the end.

[PATCH 51/94] ARM: dts: Update the parent for Audss clocks in Exynos5420
From: Tushar Behera Currently CLK_FOUT_EPLL was set as one of the parents of AUDSS mux. As per the user manual, it should be CLK_MAU_EPLL.

[PATCH 58/94] i8k: Fix non-SMP operation
From: Guenter Roeck
Commit f36fdb9f0266 (i8k: Force SMM to run on CPU 0) adds support
for multi-core CPUs to the driver. Unfortunately, that causes it
to fail loading if compiled without SMP support, at least on
32 bit kernels. Kernel log shows "i8k: unable to get SMM Dell
signature", and function i8k_smm is found to return -EINVAL.
Testing revealed that the culprit is the missing return value check
of set_cpus_allowed_ptr.

From: Tomasz Figa
Currently, the exynos cpuidle driver works correctly only on exynos4210
and 5250. Trying to use it with just one CPU online on any other exynos
SoCs will lead to system failure, due to unsupported AFTR mode on other
SoCs. This patch fixes the problem by registering the driver only on
supported SoCs and letting others simply use default WFI mode until
support for them is added.

with the default divider set to 2. l4 then derived from l3 is a fixed factor
clock, but the fixed divider is 2 and not 1. Which means the l3 clock is
half of core DPLLs h12x2 and l4 is half of l3 (as seen with this patch)

Commit 717f3bbab3c7628736ef738fdbf3d9a28578c26c,
'serial_core: Fix conditional start_tx on ring buffer not empty'
exposes an incorrect assumption in several drivers' start_tx methods;
the tx ring buffer can, in fact, be empty when restarting tx while
performing flow control.
Affected drivers:
sunsab.c
ip22zilog.c
pmac_zilog.c
sunzilog.c
m32r_sio.c
imx.c
Other in-tree serial drivers either are not affected or already
test for empty tx ring buffer before transmitting.
Test for empty tx ring buffer in start_tx() method, after transmitting
x_char (if applicable).

[PATCH 72/94] phy: omap-usb2: fix devm_ioremap_resource error detection code
From: Himangi Saraogi
devm_ioremap_resource returns an ERR_PTR value, not NULL, on failure.
A simplified version of the semantic match that finds this problem is as
follows:
//

expression e,e1;
statement S;

[PATCH 55/94] Drivers: hv: vmbus: Fix a bug in the channel callback dispatch code
From: "K. Y. Srinivasan"
Starting with Win8, we have implemented several optimizations to improve the
scalability and performance of the VMBUS transport between the Host and the
Guest. Some of the non-performance critical services cannot leverage these
optimization since they only read and process one message at a time.
Make adjustments to the callback dispatch code to account for the way
non-performance critical drivers handle reading of the channel.

[PATCH 78/94] scripts/kernel-doc: handle object-like macros
From: Horia Geanta
Object-like macros are different than function-like macros:
https://gcc.gnu.org/onlinedocs/cpp/Object-like-Macros.html
https://gcc.gnu.org/onlinedocs/cpp/Function-like-Macros.html
They are not parsed correctly, generating invalid intermediate
files (xmls) for cases like:
#define BIT_MASK(0xFF << BIT_SHIFT)
where "OxFF <<" is considered to be parameter type.
When parsing, we can differentiate beween these two types of macros by
checking whether there is at least one whitespace b/w "#define" and
first opening parenthesis.
