Function otx2_cptlf_set_dev_info() initializes common
fields of cptlfs data-struct. This function is called
every time a cptlf is initialized but this needs be done
once for a cptlf block. So this initialization is moved
to early device probe code to avoid redundant initialization.

Only add ecb to the cipher name if it isn't already ecb.
Also use memcmp instead of strncmp since these strings are all
stored in an array of length CRYPTO_MAX_ALG_NAME.

Add ahash support to hmac so that drivers that can't do hmac in

Soon hmac will support ahash. For compatibility hmac still supports
shash so it is possible for two hmac algorithms to be registered at
the same time. The shash algorithm will have the driver name
"hmac-shash(XXX-driver)". Due to a quirk in the API, there is no way
to locate the shash algorithm using the name "hmac(XXX-driver)". It
has to be addressed as either "hmac(XXX)" or "hmac-shash(XXX-driver)".
Looking it up with "hmac(XXX-driver)" will simply trigger the creation
of another instance, and on the second instantiation this will fail
with EEXIST.
Catch the error EEXIST along with ENOENT since it is expected.
If a real shash algorithm came this way, it would be addressed using
the proper name "hmac-shash(XXX-driver)".

Provide an option to handle the partial blocks in the ahash API.
Almost every hash algorithm has a block size and are only able
to hash partial blocks on finalisation.
As a first step disable virtual address support for algorithms
with state sizes larger than HASH_MAX_STATESIZE. This is OK as
virtual addresses are currently only used on synchronous fallbacks.
This means ahash_do_req_chain only needs to handle synchronous
fallbacks, removing the complexities of saving the request state.
Also move the saved request state into the ahash_request object
as nesting is no longer possible.
Add a scatterlist to ahash_request to store the partial block.

The clock properties are quite varied for each platform hence the

Enable the reporting of error counters through sysfs for QAT GEN6
devices and update the ABI documentation.
This enables the reporting of the following:
- errors_correctable - hardware correctable errors that allow the
system to recover without data loss.
- errors_nonfatal: errors that can be isolated to specific in-flight
requests.
- errors_fatal: errors that cannot be contained to a request,
requiring a Function Level Reset (FLR) upon occurrence.

Enable the reporting and handling of errors for QAT GEN6 devices.
Errors are categorized as correctable, non-fatal, or fatal. Error
handling involves reading the error source registers (ERRSOU0 to ERRSOU3)
to determine the source of the error and then decoding the actual source
reading specific registers.
The action taken depends on the error type:
- Correctable and Non-Fatal errors. These error are logged, cleared and
the corresponding counter is incremented.
- Fatal errors. These errors are logged, cleared and a Function Level
Reset (FLR) is scheduled.
This reports and handles the following errors:
- Accelerator engine (AE) correctable errors
- Accelerator engine (AE) uncorrectable errors
- Chassis push-pull (CPP) errors
- Host interface (HI) parity errors
- Internal memory parity errors
- Receive interface (RI) errors
- Transmit interface (TI) errors
- Interface for system-on-chip (SoC) fabric (IOSF) primary command
parity errors
- Shared RAM and slice module (SSM) errors

A recent patch that addressed a UAF introduced a reference count leak:
the parallel_data refcount is incremented unconditionally, regardless
of the return value of queue_work(). If the work item is already queued,
the incremented refcount is never decremented.
Fix this by checking the return value of queue_work() and decrementing
the refcount when necessary.

Add two helpers, one for posting overflows for lockless_cq rings, and
one for non-lockless_cq rings. The former can allocate sanely with
GFP_KERNEL, but needs to grab the completion lock for posting, while the
latter must do non-sleeping allocs as it already holds the completion
lock.
While at it, mark the overflow handling functions as __cold as well, as
they should not generally be called during normal operations of the
ring.

Rather than pass extra1/extra2 separately, just pass in the (now) named

Commit 925baeddc5b0 ("Btrfs: Start btree concurrency work.") added the
comment for the field keep_locks. This got moved later but without the
comment, so move it to the right place and fix the comment style.

Both regs_get_kernel_stack_nth() and regs_get_register() are not
inlined. With the new ftrace funcgraph-args feature they show up in
function graph tracing:
4) | sched_core_idle_cpu(cpu=4) {
4) 0.257 us | regs_get_register(regs=0x37fe00afa10, offset=2);
4) 0.218 us | regs_get_register(regs=0x37fe00afa10, offset=3);
4) 0.225 us | regs_get_register(regs=0x37fe00afa10, offset=4);
4) 0.239 us | regs_get_register(regs=0x37fe00afa10, offset=5);
4) 0.239 us | regs_get_register(regs=0x37fe00afa10, offset=6);
4) 0.245 us | regs_get_kernel_stack_nth(regs=0x37fe00afa10, n=20);
This is subtoptimal, since both functions are supposed to be ftrace
internal helper functions. If they appear in ftrace traces this reduces
readability significantly, plus this adds tons of extra useless extra
entries.
Address this by moving both functions and required helpers to ptrace.h and
always inline them. This way they don't appear in traces anymore. In
addition the overhead that comes with functions calls is also reduced.

asm/thread_info.h requires PAGE_SIZE, which is defined in vdso/page.h,
but doesn't need to include asm/lowcore.h or asm/page.h.
Therefore change the includes accordingly and reduce header dependencies.

When calling the diag for DCSS unload on a non-IPL CPU, the sclp maximum
memory detection on the next IPL would falsely return the end of the
previously loaded DCSS.
This is because of an issue in z/VM, so work around it by always calling
the diag for DCSS unload on IPL CPU 0. That CPU cannot be set offline,
so the dcss_diag() call can directly be scheduled to CPU 0.
The wrong maximum memory value returned by sclp would only affect KASAN
kernels. When a DCSS within the falsely reported extra memory range is
loaded and accessed again, it would result in a kernel crash:
Unable to handle kernel pointer dereference in virtual kernel address space
Failing address: 001c0000a3ffe000 TEID: 001c0000a3ffe803
