[ Upstream commit fcf88917 ]

The commit 510ded33 ("slab: implement slab_root_caches list")
changes the name of the list node within "struct kmem_cache" from "list"
to "root_caches_node", but leaks_show() still use the "list" which
causes a crash when reading /proc/slab_allocators.

You need to have CONFIG_SLAB=y and CONFIG_MEMCG=y to see the problem,
because without MEMCG all slab caches are root caches, and the "list"
node happens to be the right one.

Use parentheses around uses of the argument in u64_to_user_ptr() to
ensure that the cast doesn't apply to part of the argument.

There are existing uses of the macro of the form

  u64_to_user_ptr(A + B)

which expands to

  (void __user *)(uintptr_t)A + B

(the cast applies to the first operand of the addition, the addition
is a pointer addition). This happens to still work as intended, the
semantic difference doesn't cause a difference in behavior.

But I want to use u64_to_user_ptr() with a ternary operator in the
argument, like so:

  u64_to_user_ptr(A ? B : C)

[ Upstream commit 583feb08 ]

When an event is programmed with attr.wakeup_events=N (N>0), it means
the caller is interested in getting a user level notification after
N samples have been recorded in the kernel sampling buffer.

With precise events on Intel processors, the kernel uses PEBS.
The kernel tries minimize sampling overhead by verifying
if the event configuration is compatible with multi-entry PEBS mode.
If so, the kernel is notified only when the buffer has reached its threshold.
Other PEBS operates in single-entry mode, the kenrel is notified for each
PEBS sample.

The problem is that the current implementation look at frequency
mode and event sample_type but ignores the wakeup_events field. Thus,
it may not be possible to receive a notification after each precise event.

This patch fixes this problem by disabling multi-entry PEBS if wakeup_events
is non-zero.

[ Upstream commit d0294344 ]

The receive side mapping (RSM) on hfi1 hardware is a special
matching mechanism to direct an incoming packet to a given
hardware receive context. It has 4 instances of matching capabilities
(RSM0 - RSM3) that share the same RSM table (RMT). The RMT has a total of
256 entries, each of which points to a receive context.

Currently, three instances of RSM have been used:
1. RSM0 by QOS;
2. RSM1 by PSM FECN;
3. RSM2 by VNIC.

Each RSM instance should reserve enough entries in RMT to function
properly. Since both PSM and VNIC could allocate any receive context
between dd->first_dyn_alloc_ctxt and dd->num_rcv_contexts, PSM FECN must
reserve enough RMT entries to cover the entire receive context index
range (dd->num_rcv_contexts - dd->first_dyn_alloc_ctxt) instead of only
the user receive contexts allocated for PSM
(dd->num_user_contexts). Consequently, the sizing of
dd->num_user_contexts in set_up_context_variables is incorrect.

When an old ack_queue entry is used to store an incoming request, it may

old entry. The introduction of tid rdma specific operations in the
ack_queue makes the specific opcode tests wrong.  Multiple opcodes (RDMA
READ, TID RDMA READ, and TID RDMA WRITE) may need MR ref cleanup.

This way the CEC clock gets only enabled when needed. This can be tested

to disable it.

After commit fbeec965 ("ASoC: samsung: odroid: Fix 32000 sample rate
handling") the audio root clock frequency is configured improperly for
44100 sample rate. Due to clock rate rounding it's 20070401 Hz instead
of 22579000 Hz. This results in a too low value of the PSR clock divider
in the CPU DAI driver and too fast actual sample rate for fs=44100. E.g.
1 kHz tone has actual 1780 Hz frequency (1 kHz * 20070401/22579000 * 2).

Fix this by increasing the correction passed to clk_set_rate() to take
into account inaccuracy of the EPLL frequency properly.

[ Upstream commit 570f18b6 ]

On HDaudio platforms, if playback is started when capture is working,
there is no audible output.

This can be root-caused to the use of the rx|tx_mask to store an HDaudio
stream tag.

If capture is stared before playback, rx_mask would be non-zero on HDaudio
platform, then the channel number of playback, which is in the same codec
dai with the capture, would be changed by soc_pcm_codec_params_fixup based
on the tx_mask at first, then overwritten by this function based on rx_mask
at last.

According to the author of tx|rx_mask, tx_mask is for playback and rx_mask
is for capture. And stream direction is checked at all other references of
tx|rx_mask in ASoC, so here should be an error. This patch checks stream
direction for tx|rx_mask for fixup function.

This issue would affect not only HDaudio+ASoC, but also I2S codecs if the
channel number based on rx_mask is not equal to the one for tx_mask. It could
be rarely reproduecd because most drivers in kernel set the same channel number
to tx|rx_mask or rx_mask is zero.

Tested on all platforms using stream_tag & HDaudio and intel I2S platforms.

Consequently, when attempting to use TDA998x in S/PDIF mode, the attempt

This patch fixes a bug that prevents freeing the reset gpio on unloading
the module.

aic3x_i2c_probe is called when loading the module and it calls list_add
with a probably uninitialized list entry aic3x->list (next = prev = NULL)).
So even if list_del is called it does nothing and in the end the gpio_reset
is not freed. Then a repeated module probing fails silently because
gpio_request fails.

When moving INIT_LIST_HEAD to aic3x_i2c_probe we also have to move
list_del to aic3x_i2c_remove because aic3x_remove may be called
multiple times without aic3x_i2c_remove being called which leads to
a NULL pointer dereference.

When the lldd is processing the complete sas task in interrupt and set the

triggered at the same time. And smp_task_timedout() will complete the task
wheter the SAS_TASK_STATE_DONE is set or not. Then the sas task may freed

Fix this by calling the complete() only when SAS_TASK_STATE_DONE is not
set. And remove the check of the return value of the del_timer(). Once the
LLDD sets DONE, it must call task->done(), which will call
smp_task_done()->complete() and the task will be completed and freed

commit f87db4db upstream.

gcc warn this:

drivers/net/ethernet/stmicro/stmmac/norm_desc.c: In function ndesc_init_rx_desc:
drivers/net/ethernet/stmicro/stmmac/norm_desc.c:138:6: warning: variable 'bfsize1' set but not used [-Wunused-but-set-variable]

Like enh_desc_init_rx_desc, we should use bfsize1
in ndesc_init_rx_desc to calculate 'p->des1'

commit dce5b0bd upstream.

The only references outside of the #ifdef have been removed, so now we
get a warning in non-SMP configurations:

  mm/kmemleak.c:1404:13: error: unused function 'scan_large_block' [-Werror,-Wunused-function]

Add a new #ifdef around it.

commit 43d147be upstream.

Trigger stop can be called in situations where trigger start failed
and as such it can't be assumed the buffer is already attached to
the compressed stream or a NULL pointer may be dereferenced.

commit 61da76be upstream.

The following commits:
commit f6dd927f ("[media] media: ov7670: calculate framerate properly for ov7675")
commit 04ee6d92 ("[media] media: ov7670: add possibility to bypass pll for ov7675")
introduced the ability to bypass PLL multiplier and use input clock (xvclk)
as pixel clock output frequency for ov7675 sensor.

PLL is bypassed using register DBLV[7:6], according to ov7670 and ov7675
sensor manuals. Macros used to set DBLV register seem wrong in the
driver, as their values do not match what reported in the datasheet.

Fix by changing DBLV_* macros to use bits [7:6] and set bits [3:0] to
default 0x0a reserved value (according to datasheets).

While at there, remove a write to DBLV register in
"ov7675_set_framerate()" that over-writes the previous one to the same
register that takes "info->pll_bypass" flag into account instead of setting PLL
multiplier to 4x unconditionally.

And, while at there, since "info->pll_bypass" is only used in
set/get_framerate() functions used by ov7675 only, it is not necessary
to check for the device id at probe time to make sure that when using
ov7670 "info->pll_bypass" is set to false.
