Driver allow to use devices with disabled iCPU only.
Some devices have pre-initialised iCPU by bootloader.
That state make switch unmanaged. This patch force reset
if device is in unmanaged state. In the result chip lost
internal firmware from RAM and it can be managed.

This patch add platform part of vsc73xx driver.
It allows to use chip connected to a parallel memory bus and work in
memory-mapped I/O mode. (aka PI bus in chip manual)
By default device is working in big endian mode.

This driver (currently) only takes control of the switch chip over
SPI and configures it to route packages around when connected to a
CPU port. But Vitesse chip support also parallel interface.
This patch split driver into two parts: core and spi. It is required
for add support to another managing interface.

David reports that RPC applications which use epoll() occasionally
get stuck, and that TLS ULP causes the kernel to not wake applications,
even though read() will return data.
This is indeed true. The ctx->rx_list which holds partially copied
records is not consulted when deciding whether socket is readable.
Note that SO_RCVLOWAT with epoll() is and has always been broken for
kernel TLS. We'd need to parse all records from the TCP layer, instead
of just the first one.

Laura reported that the perf build failed in fedora when we got a glibc
that provides gettid(), which I reproduced using fedora rawhide with the
glibc-devel-2.29.9000-26.fc31.x86_64 package.
Add a feature check to avoid providing a gettid() helper in such

For these places are protected by rcu_read_lock, we change from
rcu_dereference_rtnl to rcu_dereference, as there is no need to
check if rtnl lock is held.
For these places are protected by rtnl_lock, we change from
rcu_dereference_rtnl to rtnl_dereference/rcu_dereference_protected,
as no extra memory barriers are needed under rtnl_lock() which also
protects tn->bearer_list[] and dev->tipc_ptr/b->media_ptr updating.

Commit 0126be38d988 ("kbuild: announce removal of SUBDIRS if used")
added a hint about the 'SUBDIRS' replacement, but it was not clear
enough.
Multiple people sent me similar questions, patches. For instance,
https://lkml.org/lkml/2019/1/17/456
I did not mean to use M= for building a subdirectory in the kernel tree.
From commit 669efc76b317 ("net: hns3: fix compile error"), people
already (ab)use M=... to do that because it seems to work to some extent.
Documentation/kbuild/kbuild.txt says M= and KBUILD_EXTMOD are used for
building external modules.
In fact, Kbuild supports the single target '%/' for this purpose, but
this may not be noticed much.
Kindly add more hints.
Makefile:213: ================= WARNING ================
Makefile:214: 'SUBDIRS' will be removed after Linux 5.3
Makefile:215:
Makefile:216: If you are building an individual subdirectory
Makefile:217: in the kernel tree, you can do like this:
Makefile:218: $ make path/to/dir/you/want/to/build/
Makefile:219: (Do not forget the trailing slash)

Previously steam_open.cocci was treating only wait_event_.* - e.g.
wait_event_interruptible - as a blocking operation. However e.g.
wait_for_completion_interruptible is also blocking, and so from this
point of view it would be more logical to treat all wait_.* as a
blocking point.
The logic of this change actually came up for real when
drivers/pci/switch/switchtec.c changed from using
wait_event_interruptible to wait_for_completion_interruptible:
https://lore.kernel.org/linux-pci/20190413170056.GA11293@deco.navytux.spb.ru/
https://lore.kernel.org/linux-pci/20190415145456.GA15280@deco.navytux.spb.ru/
https://lore.kernel.org/linux-pci/20190415154102.GB17661@deco.navytux.spb.ru/
For a driver that uses nonseekable_open with read/write having stream
semantic and read also calling e.g. wait_for_completion_interruptible,
running stream_open.cocci before this patch would produce:
WARNING: <driver>_fops: .read() and .write() have stream semantic; safe to change nonseekable_open -> stream_open.
while after this patch it will report:
ERROR: <driver>_fops: .read() can deadlock .write(); change nonseekable_open -> stream_open to fix.

The command line option `no387' is designed to disable the FPU
entirely. This only 'works' with CONFIG_MATH_EMULATION enabled.
But on 64bit this cannot work because user space expects SSE to work which
required basic FPU support. MATH_EMULATION does not help because SSE is not
emulated.
The command line option `nofxsr' should also be limited to 32bit because
FXSR is part of the required flags on 64bit so turning it off is not
possible.
Clearing X86_FEATURE_FPU without emulation enabled will not work anyway and
hang in fpu__init_system_early_generic() before the console is enabled.
Setting additioal dependencies, ensures that the CPU still boots on a
modern CPU. Otherwise, dropping FPU will leave FXSR enabled causing the
kernel to crash early in fpu__init_system_mxcsr().
With XSAVE support it will crash in fpu__init_cpu_xstate(). The problem is
that xsetbv() with XMM set and SSE cleared is not allowed. That means
XSAVE has to be disabled. The XSAVE support is disabled in
fpu__init_system_xstate_size_legacy() but it is too late. It can be
removed, it has been added in commit
1f999ab5a1360 ("x86, xsave: Disable xsave in i387 emulation mode")
to use `no387' on a CPU with XSAVE support.
All this happens before console output.
After hat, the next possible crash is in RAID6 detect code because MMX
remained enabled. With a 3DNOW enabled config it will explode in memcpy()
for instance due to kernel_fpu_begin() but this is unconditionally enabled.
This is enough to boot a Debian Wheezy on a 32bit qemu "host" CPU which
supports everything up to XSAVES, AVX2 without 3DNOW. Later, Debian
increased the minimum requirements to i686 which means it does not boot
userland atleast due to CMOV.
After masking the additional features it still keeps SSE4A and 3DNOW*
enabled (if present on the host) but those are unused in the kernel.
Restrict `no387' and `nofxsr' otions to 32bit only. Add dependencies for
FPU, FXSR to additionaly mask CMOV, MMX, XSAVE if FXSR or FPU is cleared.

The flag hints the user that the pinned timers will always be run on a
static CPU (because that should be what "pinned" means...) but that's
not the truth, at least with the current implementation.
For example, currently if a pinned timer is set up but later mod_timer()
upon the pinned timer is invoked, mod_timer() will still try to queue the
timer on the current processor and migrate the timer if necessary.
Document it a bit with the definition of TIMER_PINNED so that all future
users will use it correctly.

path of rawmidi interface
In IEC 61883-6, several types of sampling data can be multiplexed into
payload of common isochronous packet (CIP). For typical audio and music
units, PCM samples and MIDI messages are multiplexed into one packet
streaming.
ALSA firewire-motu driver allows applications of rawmidi interface to
start packet streaming for transmission of MIDI messages. However at
error path, the reference count of stream functionality is not operated
correctly. This can brings a bug that packet streaming is not stopped
when all referrers release the count.
This commit fixes the bug.

When using the device emulation feature (introduced in Bluefield-1 SOC),
a privileged function (the device emulation manager) will be able to
create a channel to execute commands on behalf of the emulated function.
This channel will be a general object of type VHCA_TUNNEL that will have
a unique ID for each emulated function. This ID will be passed in each
cmd that will be issued by the emulation SW in a well known offset in
the command header.
This channel is needed since the emulated function doesn't have a normal
command interface to the HCA HW, but some basic configuration for that
function is needed (e.g. initialize and enable the HCA). For that matter,
a specific command-set was defined and only those commands will be issued
by the HCA.

Instead of hardcoding the input name to the driver name
('gpio-keys-polled'), allow specifying the name of the device via
"label" property. If the property is not present (nor name is set in
board-supplied platform data), we'll default to the old name.

The kernel test robot found a regression of xfs/054 in the conversion of
bulkstat to use the new iwalk infrastructure -- if a caller set *lastip
= 128 and invoked FSBULKSTAT_SINGLE, the bstat info would be for inode
128, but *lastip would be increased by the kernel to 129.
FSBULKSTAT_SINGLE never incremented lastip before, so it's incorrect to
make such an update to the internal lastino value now.

initialization
Some compilers will complain when using a member of a struct to
initialize another member, in the same struct initialization.
For instance:
debian:8 Debian clang version 3.5.0-10 (tags/RELEASE_350/final) (based on LLVM 3.5.0)
oraclelinux:7 clang version 3.4.2 (tags/RELEASE_34/dot2-final)
Produce:
ui/browsers/annotate.c:104:12: error: variable 'ops' is uninitialized when used within its own initialization [-Werror,-Wuninitialized]
(!ops.current_entry ||
^~~
1 error generated.
So use an extra variable, initialized just before that struct, to have
the value used in the expressions used to init two of the struct
members.
