Prevent incrementing device->commands_outstanding for ioaccel command
retries that are driver initiated. If the command goes through the retry
path, the device->commands_outstanding counter has already accounted for
the number of commands outstanding to the device. Only commands going
through function hpsa_cmd_resolve_events decrement this counter.
- ioaccel commands go to either HBA disks or to logical volumes comprised
of SSDs.
The extra increment is causing device resets to hang.
- Resets wait for all device outstanding commands to complete before
returning.
Replace unused field abort_pending with retry_pending. This is a
maintenance driver so these changes have the least impact/risk.

The SCSI core has been modified recently such that it only processes PM
requests if rpm_status != RPM_ACTIVE. Since some Opal requests are
submitted while rpm_status != RPM_ACTIVE, set flag RQF_PM for Opal
requests.

When user deletes a tcmu device via configFS, tcmu calls
uio_unregister_device(). During that call uio resets its pointer to struct
uio_info provided by tcmu. That means, after uio_unregister_device() uio
will no longer execute any of the callbacks tcmu had set in uio_info.
Especially, if userspace daemon still holds the corresponding uio device
open or mmap'ed while tcmu calls uio_unregister_device(), uio will not call
tcmu_release() when userspace finally closes and munmaps the uio device.
Since tcmu does refcounting for the tcmu device in tcmu_open() and
tcmu_release(), in the decribed case refcount does not drop to 0 and tcmu
does not free tcmu device's resources. In extreme cases this can cause
memory leaking of up to 1 GB for a single tcmu device.
After uio_unregister_device(), uio will reject every open, read, write,
mmap from userspace with -EOI. But userspace daemon can still access the
mmap'ed command ring and data area. Therefore tcmu should wait until
userspace munmaps the uio device before it frees the resources, as we don't
want to cause SIGSEGV or SIGBUS to user space.
That said, current refcounting during tcmu_open and tcmu_release does not
work correctly, and refcounting better should be done in the open and close
callouts of the vm_operations_struct, which tcmu assigns to each mmap of
the uio device (because it wants its own page fault handler).
This patch fixes the memory leak by removing refcounting from tcmu_open and
tcmu_close, and instead adding new tcmu_vma_open() and tcmu_vma_close()
handlers that only do refcounting.

Dan reported we're passing in GFP_NOIO to kvmalloc() which will then
fallback to doing kmalloc() instead of an optional vmalloc() if the size
exceeds kmalloc()s limits. This will break with drives that have zone
numbers exceeding PAGE_SIZE/sizeof(u32).
Instead of passing in GFP_NOIO, enter an implicit GFP_NOIO allocation
scope.

TCM doesn't properly handle underflow case for service actions. One way to
prevent it is to always complete command with
target_complete_cmd_with_length(), however it requires access to data_sg,
which is not always available.
This change introduces target_set_cmd_data_length() function which allows
to set command data length before completing it.

When cifsacl mount option is used, retain the ACEs which
should not be modified during chmod. Following is the approach taken:
1. Retain all explicit (non-inherited) ACEs, unless the SID is one
of owner/group/everyone/authenticated-users. We're going to set new
ACEs for these SIDs anyways.
2. At the end of the list of explicit ACEs, place the new list of
ACEs obtained by necessary conversion/encoding.
3. Once the converted/encoded ACEs are set, copy all the remaining
ACEs (inherited) into the new ACL.

MPJ subflows are not exposed as fds to user spaces. As such,
incoming MPJ subflows are removed from the accept queue by
tcp_check_req()/tcp_get_cookie_sock().
Later tcp_child_process() invokes subflow_data_ready() on the
parent socket regardless of the subflow kind, leading to poll
wakeups even if the later accept will block.
Address the issue by double-checking the queue state before
waking the user-space.

If the msk is closed before sending or receiving any data,
no DATA_FIN is generated, instead an MPC ack packet is
crafted out.
In the above scenario, the MPTCP protocol creates and sends a
pure ack and such packets matches also the criteria for an
MPC ack and the protocol tries first to insert MPC options,
leading to the described error.
This change addresses the issue by avoiding the insertion of an
MPC option for DATA_FIN packets or if the sub-flow is not
established.
To avoid doing multiple times the same test, fetch the data_fin
flag in a bool variable and pass it to both the interested
helpers.

Current population code populates a whole page table without taking care
of what could have been already allocated and without taking into account
possible index in page table, assuming the virtual address to map is always
aligned on the page table size, which, for example, won't be the case when
the kernel will get pushed to the end of the address space.
Address those problems by rewriting the kasan population function,

At early boot stage, we have a whole PGDIR to map the kernel, so there
is no need to restrict the early mapping size to 128MB. Removing this
define also allows us to simplify some compile time logic.
This fixes large kernel mappings with a size greater than 128MB, as it
is the case for syzbot kernels whose size was just ~130MB.
Note that on rv64, for now, we are then limited to PGDIR size for early
mapping as we can't use PGD mappings (see [1]). That should be enough
given the relative small size of syzbot kernels compared to PGDIR_SIZE
which is 1GB.

We use the generic C VDSO implementations of a handful of clock-related
functions. When kasan is enabled this results in asan stub calls that
are unlikely to be resolved by userspace, this just disables KASAN
when building the VDSO.
Verified the fix on a kernel with KASAN enabled using vDSO selftests.

The nommu_k210_defconfig default configuration allows booting a Canaan
Kendryte K210 SoC based boards using an embedded intramfs cpio file.
Modifying this configuration to enable support for the board SD card is
not trivial for all users. To help beginners getting started with these
boards, add the nommu_k210_sdcard_defconfig default configuration file
to set all configuration options necessary to use the board mmc-spi sd
card for the root file system.
This new configuration adds support for the block layer, the mmc-spi
driver and modifies the boot options to specify the rootfs device as
mmcblk0p1 (first partition of the sd card block device). The ext2 file
system is selected by default to encourage its use as that results in
only about 4KB added to the kernel image size. As ext2 does not have
journaling, the boot options specify a read-only mount of the file
system. Similarly to the smaller nommu_k210_defconfig, this new default
configuration disables virtual terminal support to reduce the kernel
image size.
The default device tree selected is unchanged, specifying the simple
"k210_generic" device tree file. The user must change this setting to
specify the device tree suitable for the board being used
(sipeed_maix_bit, sipeed_maix_dock, sipeed_maix_go, sipeed_maixduino or
canaan_kd233).

Update the Kendryte k210 nommu default configuration file
(nommu_k210_defconfig) to include device drivers for reset, reboot,
I2C, SPI, gpio and LEDs support. Virtual Terminal support is also
disabled as no terminal devices are supported and enabled. Disabling
CONFIG_VT (removing the no longer needed override for
CONFIG_VGA_CONSOLE) reduces the kernel image size by about 65 KB.
This default configuration remains suitable for a system using an
initramfs cpio file linked into the kernel image.

Update the Canaan Kendryte K210 base device tree k210.dtsi to define
all supported peripherals of the SoC, their clocks and reset lines.
The device tree file k210.dts is renamed to k210_generic.dts and
becomes the default value selection of the configuration option
SOC_CANAAN_K210_DTB_BUILTIN_SOURCE. No device beside the serial console
is defined by this device tree. This makes this generic device tree
suitable for use with a builtin initramfs with all known K210 based
boards.
These changes result in the K210_CLK_ACLK clock ID to be unused and
removed from the dt-bindings k210-clk.h header file.
Most updates to the k210.dtsi file come from Sean Anderson's work on
U-Boot support for the K210.

The sifive gpio IP block supports up to 32 GPIOs. Reflect that in the
interrupts property description and maxItems. Also add the standard
ngpios property to describe the number of GPIOs available on the
implementation.
Also add the "canaan,k210-gpiohs" compatible string to indicate the use
of this gpio controller in the Canaan Kendryte K210 SoC. If this
compatible string is used, do not define the clocks property as
required as the K210 SoC does not have a software controllable clock
for the Sifive gpio IP block.
