Nothing really major this release, despite quite a lot of activity. Just lots of
things all over the place.
Some things of note include:
- Access via perf to a new type of PMU (IMC) on Power9, which can count both
core events as well as nest unit events (Memory controller etc).
- Optimisations to the radix MMU TLB flushing, mostly to avoid unnecessary Page
Walk Cache (PWC) flushes when the structure of the tree is not changing.
- Reworks/cleanups of do_page_fault() to modernise it and bring it closer to
other architectures where possible.
- Rework of our page table walking so that THP updates only need to send IPIs
to CPUs where the affected mm has run, rather than all CPUs.
- The size of our vmalloc area is increased to 56T on 64-bit hash MMU systems.
This avoids problems with the percpu allocator on systems with very sparse
NUMA layouts.
- STRICT_KERNEL_RWX support on PPC32.
- A new sched domain topology for Power9, to capture the fact that pairs of
cores may share an L2 cache.
- Power9 support for VAS, which is a new mechanism for accessing coprocessors,
and initial support for using it with the NX compression accelerator.
- Major work on the instruction emulation support, adding support for many new
instructions, and reworking it so it can be used to implement the emulation
needed to fixup alignment faults.
- Support for guests under PowerVM to use the Power9 XIVE interrupt controller.
And probably that many things again that are almost as interesting, but I had to
keep the list short. Plus the usual fixes and cleanups as always.

This patch adds P9 NX support for 842 compression engine. Virtual
Accelerator Switchboard (VAS) is used to access 842 engine on P9.
For each NX engine per chip, setup receive window using
vas_rx_win_open() which configures RxFIFo with FIFO address, lpid,
pid and tid values. This unique (lpid, pid, tid) combination will
be used to identify the target engine.
For crypto open request, open send window on the NX engine for
the corresponding chip / cpu where the open request is executed.
This send window will be closed upon crypto close request.
NX provides high and normal priority FIFOs. For compression /
decompression requests, we use only hight priority FIFOs in kernel.
Each NX request will be communicated to VAS using copy/paste
instructions with vas_copy_crb() / vas_paste_crb() functions.

There are quite a number of occurrences in the kernel of the pattern
if (dst != src)
memcpy(dst, src, walk.total % AES_BLOCK_SIZE);
crypto_xor(dst, final, walk.total % AES_BLOCK_SIZE);
or
crypto_xor(keystream, src, nbytes);
memcpy(dst, keystream, nbytes);
where crypto_xor() is preceded or followed by a memcpy() invocation
that is only there because crypto_xor() uses its output parameter as
one of the inputs. To avoid having to add new instances of this pattern
in the arm64 code, which will be refactored to implement non-SIMD
fallbacks, add an alternative implementation called crypto_xor_cpy(),
taking separate input and output arguments. This removes the need for
the separate memcpy().

Remove unnecessary static on local variable sha_dd. Such variable
is initialized before being used, on every execution path throughout
the function. The static has no benefit and, removing it reduces the
object file size.
This issue was detected using Coccinelle and the following semantic patch:
https://github.com/GustavoARSilva/coccinelle/blob/master/static/static_unused.cocci
In the following log you can see a significant difference in the object
file size. This log is the output of the size command, before and after
the code change:

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Add support for using the caam/jr backend on DPAA2-based SoCs.
These have some particularities we have to account for:
-HW S/G format is different
-Management Complex (MC) firmware initializes / manages (partially)
the CAAM block: MCFGR, QI enablement in QICTL, RNG

A check is performed on the ipad/opad in the safexcel_hmac_sha1_setkey
function, but the index used by the loop doing it is wrong. It is
currently the size of the state array while it should be the size of a
sha1 state. This patch fixes it.

The safexcel_hmac_sha1_setkey function checks if an invalidation command
should be issued, i.e. when the context ipad/opad change. This checks is
done after filling the ipad/opad which and it can't be true. The patch
fixes this by moving the check before the ipad/opad memcpy operations.

This module register a HASH module that support multiples
algorithms: MD5, SHA1, SHA224, SHA256.
It includes the support of HMAC hardware processing corresponding
to the supported algorithms. DMA or IRQ mode are used depending
on data length.
