The kfree_sensitive is a kernel API to clear sensitive information
that should not be leaked to other future users of the same memory
objects and free the memory. Its function is the same as the
combination of memzero_explicit and kfree. Thus, we can replace the
combination APIs with the single kfree_sensitive API.

The tdes dev gets allocated to the tfm at alg->init time, there's no
need to overwrite the pointer to tdes_dd afterwards.
There's a single IP per SoC anyway, the first entry from the
atmel_tdes.dev_list is chosen without counting for tfms for example,
in case one thinks of an even distribution of tfms across the TDES
IPs: there's only one. At alg->init time the ctx->dd should already

A few SoC (code) changes have queued up this cycle, mostly for minor
changes and some refactoring and cleanup of legacy platforms. This
branch also contains a few of the fixes that weren't sent in by the end
of the release (all fairly minor).
- Adding an additional maintainer for the TEE subsystem (Sumit Garg)
- Quite a significant modernization of the IXP4xx platforms by Linus
Walleij, revisiting with a new PCI host driver/binding, removing legacy
mach/* include dependencies and moving platform detection/config to
drivers/soc. Also some updates/cleanup of platform data.
- Core power domain support for Tegra platforms, and some improvements
in build test coverage by adding stubs for compile test targets.
- A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP
support on i.MX7D, SoC ID setup for i.MX50, removal of platform data
and board fixups for iMX6/7.
... and a few smaller changes and fixes for Samsung, OMAP, Allwinner,
Rockchip.

The open interface of the sva prefetching function is distinguish the chip
version. But the close interface of the sva prefetching function doesn't
distinguish the chip version. As a result, the sva prefetching close
operation is also performed on Kunpeng920, those registers are important
on Kunpeng920, which eventually leads to abnormal hardware problems. So
need to fix it immediately.

The function nx842_OF_upd_status triggers a sparse RCU warning when
it directly dereferences the RCU-protected devdata. This appears
to be an accident as there was another variable of the same name
that was passed in from the caller.
After it was removed (because the main purpose of using it, to
update the status member was itself removed) the global variable
unintenionally stood in as its replacement.
This patch restores the devdata parameter.

Export NX-GZIP capabilities to usrespace in sysfs
/sys/devices/vio/ibm,compression-v1/nx_gzip_caps directory.
These are queried by userspace accelerator libraries to set
minimum length heuristics and maximum limits on request sizes.
NX-GZIP capabilities:
min_compress_len /*Recommended minimum compress length in bytes*/
min_decompress_len /*Recommended minimum decompress length in bytes*/
req_max_processed_len /* Maximum number of bytes processed in one
request */
NX will return RMA_Reject if the request buffer size is greater
than req_max_processed_len.

The hypervisor provides different NX capabilities that it
supports. These capabilities such as recommended minimum
compression / decompression lengths and the maximum request
buffer size in bytes are used to define the user space NX
request.
NX will reject the request if the buffer size is more than
the maximum buffer size. Whereas compression / decompression
lengths are recommended values for better performance.

specific features that the hypervisor supports. Then retrieve

Mailbox region configuration has some changes on CN10K platform
from OcteonTX2(CN9XX) platform.
On CN10K platform:
The DRAM region allocated to PF is enumerated as PF BAR4 memory.
PF BAR4 contains AF-PF mbox region followed by its VFs mbox region.
AF-PF mbox region base address is configured at RVU_AF_PFX_BAR4_ADDR
PF-VF mailbox base address is configured at
RVU_PF(x)_VF_MBOX_ADDR = RVU_AF_PF()_BAR4_ADDR+64KB. PF access its
mbox region via BAR4, whereas VF accesses PF-VF DRAM mailboxes via
BAR2 indirect access.
On CN9XX platform:
Mailbox region in DRAM is divided into two parts AF-PF mbox region and
PF-VF mbox region i.e all PFs mbox region is contiguous similarly all
VFs.
The base address of the AF-PF mbox region is configured at
RVU_AF_PF_BAR4_ADDR.
AF-PF1 mbox address can be calculated as RVU_AF_PF_BAR4_ADDR * mbox
size.
This patch changes mbox initialization to support both CN9XX and CN10K
platform.
This patch also removes platform specific name from the PF/VF driver name
to make it appropriate for all supported platforms.

The ixp4xx_crypto driver traditionally registers a bare platform
device without attaching it to a driver, and detects the hardware
at module init time by reading an SoC specific hardware register.
Change this to the conventional method of registering the platform
device from the platform code itself when the device is present,
turning the module_init/module_exit functions into probe/release
driver callbacks.
This enables compile-testing as well as potentially having ixp4xx
coexist with other ARMv5 platforms in the same kernel in the future.

Kunpeng930 could be able to close master ooo when NFE occurs, which will
disable memory accessing from device and execute tasks. This ensures that
errors do not spread.
This patch enables the hardware to close master ooo when an error occurs
by writing hardware registers, and ensures that the driver will not drain
qp because the hardware will empty the tasks automatically.

In order to avoid reporting an exception but the error type is not
configured, the driver needs to configure the error type first, and then
enable the error interrupt. Before executing the task, hardware error
initialization is needed so that the hardware can detect the error in time.
