This patch adds files related to memory management and here is our
memory-layout:

   Fixmap       : 0xffc02000 – 0xfffff000       (4 MB - 12KB)
   Pkmap        : 0xff800000 – 0xffc00000       (4 MB)
   Vmalloc      : 0xf0200000 – 0xff000000       (238 MB)
   Lowmem       : 0x80000000 – 0xc0000000       (1GB)

abiv1 CPU (CK610) is VIPT cache and it doesn't support highmem.
abiv2 CPUs are all PIPT cache and they could support highmem.

Lowmem is directly mapped by msa0 & msa1 reg, and we needn't setup
memory page table for it.

Code of Conduct Interpretation: Add document explaining how the Code of Conduct is to be interpreted

The Contributor Covenant Code of Conduct is a general document meant to
provide a set of rules for almost any open source community.  Every
open-source community is unique and the Linux kernel is no exception.
Because of this, this document describes how we in the Linux kernel
community will interpret it.  We also do not expect this interpretation
to be static over time, and will adjust it as needed.

This document was created with the input and feedback of the TAB as well
as many current kernel maintainers.

As it was originally worded, this paragraph requires maintainers to
enforce the code of conduct, or face potential repercussions.  It sends
the wrong message, when really we just want maintainers to be part of
the solution and not violate the code of conduct themselves.

Removing it doesn't limit our ability to enforce the code of conduct,
and we can still encourage maintainers to help maintain high standards
for the level of discourse in their subsystem.

This reverts commit 8e326289.

This patch results in unnecessary netlink notification when one
tries to delete a neigh entry already in NUD_FAILED state. Found
this with a buggy app that tries to delete a NUD_FAILED entry
repeatedly. While the notification issue can be fixed with more
checks, adding more complexity here seems unnecessary. Also,
recent tests with other changes in the neighbour code have
shown that the INCOMPLETE and PROBE checks are good enough for
the original issue.

The loop wants to skip previously dumped addresses, so loops until
current index >= saved index. If the message fills it wants to save
the index for the next address to dump - ie., the one that did not
fit in the current message.

Currently, it is incrementing the index counter before comparing to the
saved index, and then the saved index is off by 1 - it assumes the
current address is going to fit in the message.

Change the index handling to increment only after a succesful dump.

We've been getting checksum errors involving small UDP packets, usually
59B packets with 1 extra non-zero padding byte. netdev_rx_csum_fault()
has been complaining that HW is providing bad checksums. Turns out the
problem is in pskb_trim_rcsum_slow(), introduced in commit 88078d98
("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE are friends").

The source of the problem is that when the bytes we are trimming start
at an odd address, as in the case of the 1 padding byte above,
skb_checksum() returns a byte-swapped value. We cannot just combine this
with skb->csum using csum_sub(). We need to use csum_block_sub() here
that takes into account the parity of the start address and handles the
swapping.

Matches existing code in __skb_postpull_rcsum() and esp_remove_trailer().

  "tracing: A few small fixes to synthetic events

   Masami found some issues with the creation of synthetic events.  The
   first two patches fix handling of unsigned type, and handling of a
   space before an ending semi-colon.

   The third patch adds a selftest to test the processing of synthetic
   events."
