Fix two issues:

When called for PTRACE_TRACEME, ptrace_link() would obtain an RCU
reference to the parent's objective credentials, then give that pointer
to get_cred().  However, the object lifetime rules for things like
struct cred do not permit unconditionally turning an RCU reference into
a stable reference.

PTRACE_TRACEME records the parent's credentials as if the parent was
acting as the subject, but that's not the case.  If a malicious
unprivileged child uses PTRACE_TRACEME and the parent is privileged, and
at a later point, the parent process becomes attacker-controlled
(because it drops privileges and calls execve()), the attacker ends up
with control over two processes with a privileged ptrace relationship,
which can be abused to ptrace a suid binary and obtain root privileges.

Fix both of these by always recording the credentials of the process
that is requesting the creation of the ptrace relationship:
current_cred() can't change under us, and current is the proper subject
for access control.

This change is theoretically userspace-visible, but I am not aware of
any code that it will actually break.

I ran into an intriguing bug caused by
commit ""spi: gpio: Don't request CS GPIO in DT use-case"
affecting all SPI GPIO devices with an active high
chip select line.

The commit switches the CS gpio handling over to the GPIO
core, which will parse and handle "cs-gpios" from the OF
node without even calling down to the driver to get the
job done.

However the GPIO core handles the standard bindings in
Documentation/devicetree/bindings/spi/spi-controller.yaml
that specifies that active high CS needs to be specified
using "spi-cs-high" in the DT node.

The code in drivers/spi/spi-gpio.c never respected this
and never tried to inspect subnodes to see if they contained
"spi-cs-high" like the gpiolib OF quirks does. Instead the
only way to get an active high CS was to tag it in the
device tree using the flags cell such as
cs-gpios = <&gpio 4 GPIO_ACTIVE_HIGH>;

This alters the quirks to not inspect the subnodes of SPI
masters on "spi-gpio" for the standard attribute "spi-cs-high",
making old device trees work as expected.

This semantic is a bit ambigous, but just allowing the
flags on the GPIO descriptor to modify polarity is what
the kernel at large mostly uses so let's encourage that.

ftrace/x86: Anotate text_mutex split between ftrace_arch_code_modify_post_process() and ftrace_arch_code_modify_prepare()

ftrace_arch_code_modify_prepare() is acquiring text_mutex, while the

This has already been documented in the code, but let's also make the fact
that this is intentional clear to the semantic analysis tools such as sparse.

LINE6 drivers allocate the buffers based on the value returned from
usb_maxpacket() calls.  The manipulated device may return zero for
this, and this results in the kmalloc() with zero size (and it may
succeed) while the other part of the driver code writes the packet
data with the fixed size -- which eventually overwrites.

This patch adds a simple sanity check for the invalid buffer size for
avoiding that problem.

The widget_mutex was introduced to serialize callers to
hda_widget_sysfs_{re}init. However, its protection of the sysfs widget array
is incomplete. For example, it is acquired around the call to
hda_widget_sysfs_reinit(), which actually creates the new array, but isn't
still acquired when codec->num_nodes and codec->start_nid is updated. So
the lock ensures one thread sets up the new array at a time, but doesn't
ensure which thread's value will end up in codec->num_nodes. If a larger
num_nodes wins but a smaller array was set up, the next call to
refresh_widgets() will touch free memory as it iterates over codec->num_nodes
that aren't there.

The widget_lock really protects both the tree as well as codec->num_nodes,
start_nid, and end_nid, so make sure it's held across that update. It should
also be held during snd_hdac_get_sub_nodes(), so that a very old read from that
function doesn't end up clobbering a later update.

In IEC 61883-6, 8 MIDI data streams are multiplexed into single
MIDI conformant data channel. The index of stream is calculated by
modulo 8 of the value of data block counter.

In fireworks, the value of data block counter in CIP header has a quirk
with firmware version v5.0.0, v5.7.3 and v5.8.0. This brings ALSA
IEC 61883-1/6 packet streaming engine to miss detection of MIDI
messages.

This commit fixes the miss detection to modify the value of data block
counter for the modulo calculation.

For maintainers, this bug exists since a commit 18f5ed36 ("ALSA:
fireworks/firewire-lib: add support for recent firmware quirk") in Linux
kernel v4.2. There're many changes since the commit.  This fix can be
backported to Linux kernel v4.4 or later. I tagged a base commit to the
backport for your convenience.

Besides, my work for Linux kernel v5.3 brings heavy code refactoring and
some structure members are renamed in 'sound/firewire/amdtp-stream.h'.
The content of this patch brings conflict when merging -rc tree with
this patch and the latest tree. I request maintainers to solve the
conflict to replace 'tx_first_dbc' with 'ctx_data.tx.first_dbc'.

Pull RISC-V fixes from Paul Walmsley:
 "Minor RISC-V fixes and one defconfig update.

  The fixes have no functional impact:

   - Fix some comment text in the memory management vmalloc_fault path.

   - Fix some warnings from the DT compiler in our newly-added DT files.

   - Change the newly-added DT bindings such that SoC IP blocks with
     external I/O are marked as "disabled" by default, then enable them
     explicitly in board DT files when the devices are used on the
     board. This aligns the bindings with existing upstream practice.

   - Add the MIT license as an option for a minor header file, at the
     request of one of the U-Boot maintainers.

  The RISC-V defconfig update builds the SiFive SPI driver and the
  MMC-SPI driver by default. The intention here is to make v5.2 more
  usable for testers and users with RISC-V hardware"

Pull two more NFS client fixes from Anna Schumaker:
 "These are both stable fixes.

  One to calculate the correct client message length in the case of
  partial transmissions. And the other to set the proper TCP timeout for
  flexfiles"

Pull block fixes from Jens Axboe:
 "Just two small fixes.

  One from Paolo, fixing a silly mistake in BFQ. The other one is from
  me, ensuring that we have ->file cleared in the io_uring request a bit
  earlier. That avoids a use-before-free, if we encounter an error
  before ->file is assigned"
