Many MIPS CPUs have optional CPU features which are not activates for
all CPU cores. Print the CPU options which are implemented in the core
in /proc/cpuinfo. This makes it possible to see what features are
supported and which are not supported. This should cover all standard
MIPS extensions, before it only printed information about the main MIPS
ASEs.

The Eon EN25QH64 is a 64 Mbit SPI NOR flash memory chip. Its 32, 128 and
256 Mbits siblings are supported upstream but this particular size wasn't.
This commit includes patches for kernels 4.14 and 4.19.
Tested on a COMFAST CF-E120A v3 (ath79).

The WD MyBook Live SquashFS images didn't work anymore due to
a upstream regression in f2fs commit: 0cfe75c5b01199
("f2fs: enhance sanity_check_raw_super() to avoid potential overflows")
that got backported to 4.14.86 and landed in 4.18.
by Martin Blumenstingl:
|Treat "block_count" from struct f2fs_super_block as 64-bit little endian
|value in sanity_check_raw_super() because struct f2fs_super_block
|declares "block_count" as "__le64".
|
|This fixes a bug where the superblock validation fails on big endian
|devices with the following error:
| F2FS-fs (sda1): Wrong segment_count / block_count (61439 > 0)
| F2FS-fs (sda1): Can't find valid F2FS filesystem in 1th superblock
| F2FS-fs (sda1): Wrong segment_count / block_count (61439 > 0)
| F2FS-fs (sda1): Can't find valid F2FS filesystem in 2th superblock
|As result of this the partition cannot be mounted.
|
|With this patch applied the superblock validation works fine and the
|partition can be mounted again:
| F2FS-fs (sda1): Mounted with checkpoint version = 7c84
|
|My little endian x86-64 hardware was able to mount the partition without
|this fix.
|To confirm that mounting f2fs filesystems works on big endian machines
|again I tested this on a 32-bit MIPS big endian (lantiq) device.
Hopefully, this will do until Martin's patch moved through upstream
to -stable.

This patch, in a variety of forms, has been around since beginning 2016
as e756c2bb07, ending up in present form 0aa6c7df60 (kernel 4.4.13 bump)
and carried forward ever since.
There have been a number of MIPS kernel memory handling changes since,
including VDSO fixes that meant openwrt patches have been dropped with
no apparent fallout.
Simple tests (ntfs-3g) on a HIGHMEM 512MB mt7621 device have not turned
up data corruption issues which would otherwise be expected. Similarly
running on other MIPS based devices for the past 2 months hasn't turned
up anything obvious to retain this out of tree patch.
With thanks to Rosen Penev for testing on the known 'highmem' device and
Felix Fietkau for testing advice. Not putting acked-by as it's my fault
if it breaks :-)

I've sent this one upstream. This patch is critical if you want to run
with "prove lock correctness" (lockdep) and you happen to have certain
mtd devices. The misuse of the uninitialized object is undefined
behaviour, but being zeroed it does not appear to have actually broken
anything other than the lockdep engine.

This makes the patches which were just copied in the previous commit
apply on top of kernel 4.19.
The patches in the backports-4.19 folder were checked if they are really
in kernel 4.19 based on the title and only removed if they were found in
the upstream kernel.
The following additional patches form the pending folder went into
upstream Linux 4.19:
pending-4.19/171-usb-dwc2-Fix-inefficient-copy-of-unaligned-buffers.patch
pending-4.19/190-2-5-e1000e-Fix-wrong-comment-related-to-link-detection.patch
pending-4.19/478-mtd-spi-nor-Add-support-for-XM25QH64A-and-XM25QH128A.patch
pending-4.19/479-mtd-spi-nor-add-eon-en25qh32.patch
pending-4.19/950-tty-serial-exar-generalize-rs485-setup.patch
pending-4.19/340-MIPS-mm-remove-mips_dma_mapping_error.patch
Bigger changes were introduced to the m25p80 spi nor driver, as far as I
saw it in the new code, it now has the functionality provided in this
patch:
pending-4.19/450-mtd-m25p80-allow-fallback-from-spi_flash_read-to-reg.patch
Part of this patch went upstream independent of OpenWrt:
hack-4.19/220-gc_sections.patch
This patch was reworked to match the changes done upstream.
The MIPS DMA API changed a lot, this patch was rewritten to match the
new DMA handling:
pending-4.19/341-MIPS-mm-remove-no-op-dma_map_ops-where-possible.patch
I did bigger manual changes to the following patches and I am not 100% sure if they are all correct:
pending-4.19/0931-w1-gpio-fix-problem-with-platfom-data-in-w1-gpio.patch
pending-4.19/411-mtd-partial_eraseblock_write.patch
pending-4.19/600-netfilter_conntrack_flush.patch
pending-4.19/611-netfilter_match_bypass_default_table.patch
pending-4.19/670-ipv6-allow-rejecting-with-source-address-failed-policy.patch
hack-4.19/211-host_tools_portability.patch
hack-4.19/221-module_exports.patch
hack-4.19/321-powerpc_crtsavres_prereq.patch
hack-4.19/902-debloat_proc.patch
