Triple Modular Redundancy(TMR) subsystem contains three microblaze cores,
subsystem is fault-tolerant and continues to operate nominally after
encountering an error. Together with the capability to detect and recover
from errors, the implementation ensures the reliability of the entire
subsystem. TMR Manager is responsible for performing recovery of the
subsystem detects the fault via a break signal it invokes microblaze
software break handler which calls the tmr manager driver api to
update the error count and status, added support for fault detection

UACCE adds the hardware error isolation feature. To improve service
reliability, some uacce devices that frequently encounter hardware
errors are isolated. Therefore, this feature is added.
Users can configure the hardware error threshold by 'isolate_strategy'
sysfs node. The user space can get the device isolated state by 'isolate'
sysfs node. If the number of device errors exceeds the configured error
threshold, the device will be isolated. It means the uacce device is
unavailable.

It's common for drivers that share same physical components to also
duplicate source code (or at least portions of it). A good example is
both drivers/gpu/drm/amdgpu/* and drivers/gpu/drm/radeon/* have a header
file called atombios.h.
While their contents aren't the same, a lot of their structs have
the exact same names which makes navigating through the code base a bit
messy as cscope will show up 'references' across drivers which aren't
exactly correct.
Add IGNORE_DIRS variable, which specifies which directories
to be ignored from indexing.
Example:
make ARCH=x86 IGNORE_DIRS="drivers/gpu/drm/radeon tools" cscope

The reason is that idt_init() returns i2c_add_driver() directly without
checking its return value, if i2c_add_driver() failed, it returns without
destroy the newly created debugfs, resulting the debugfs of idt_csr can
never be created later.

In the original implementation of dwmac5
commit 8bf993a587 ("net: stmmac: Add support for DWMAC5 and implement Safety Features")
all safety features were enabled by default.
Later it seems some implementations didn't have support for all the
features, so in
commit 5ac712dcdf ("net: stmmac: enable platform specific safety features")
the safety_feat_cfg structure was added to the callback and defined for
some platforms to selectively enable these safety features.
The problem is that only certain platforms were given that software
support. If the automotive safety package bit is set in the hardware
features register the safety feature callback is called for the platform,
and for platforms that didn't get a safety_feat_cfg defined this results
in the following NULL pointer dereference:

Go back to the original behavior, if the automotive safety package
is found to be supported in hardware enable all the features unless
safety_feat_cfg is passed in saying this particular platform only
supports a subset of the features.

octeontx2-af: Miscellaneous changes for CPT
This patchset consists of miscellaneous changes for CPT.
- Adds a new mailbox to reset the requested CPT LF.
- Modify FLR sequence as per HW team suggested.
- Adds support to recover CPT engines when they gets fault.
- Updates CPT inbound inline IPsec configuration mailbox,
as per new generation of the OcteonTX2 chips.
- Adds a new mailbox to return CPT FLT Interrupt info.

v2:
- Addressed a review comment.
v1:
- Dropped patch "octeontx2-af: Fix interrupt name strings completely"
to submit to net.

CPT HW would trigger the CPT AF FLT interrupt when CPT engines
hits some uncorrectable errors and AF is the one which receives
the interrupt and recovers the engines.
This patch adds a mailbox for CPT VFs to request for CPT faulted
and recovered engines info.

The CN10K CPT coprocessor contains a context processor
to accelerate updates to the IPsec security association
contexts. The context processor contains a context cache.
This patch updates CPT LF ALLOC mailbox to config ctx_ilen
requested by VFs. CPT_LF_ALLOC:ctx_ilen is the size of
initial context fetch.

CN10K CPT coprocessor includes a component named RXC which
is responsible for reassembly of inner IP packets. RXC has
the feature to evict oldest entries based on age/threshold.
The age/threshold is being set to minimum values to evict
all entries at the time of teardown.
This patch adds code to restore timeout and threshold config
after teardown sequence is complete as it is global config.

On OcteonTX2 platform CPT instruction enqueue is only
possible via LMTST operations.
The existing FLR sequence mentioned in HRM requires
a dummy LMTST to CPT but LMTST can't be submitted from
AF driver. So, HW team provided a new sequence to avoid
dummy LMTST. This patch adds code for the same.

On OcteonTX2 SoC, the admin function (AF) is the only one with all
priviliges to configure HW and alloc resources, PFs and it's VFs
have to request AF via mailbox for all their needs.

- Prevent reading into undefined memory in the expression lexer,
accounting for a trailer backslash followed by the null byte.
- Fix file mode when copying files to the build id cache, the problem
happens when the cache directory is in a different file system than the
file being cached, otherwise the mode was preserved as only a hard link
would be done to save space.
- Fix a related build-id 'perf test' entry that checked that permission
when caching PE (Portable Executable) files, used when profiling
Windows executables under wine.
