Optimize memcpy_{from,to}io() and memset_io() by transferring in
64 bit as much as possible with minimized barrier usage. This
simplest optimization brings faster throughput compare to current
byte-by-byte read and write with barrier in the loop. Code's
skeleton is taken from the powerpc & arm64.

Try to access RAM with the largest bit width possible, but without
doing unaligned accesses.
A further improvement could be to use multiple read and writes as the
assembly version was trying to do.
Tested on a BeagleV Starlight with a SiFive U74 core, where the

Add a device tree for the 8MNANOD3L-EVK eval board which features an
IMX8MN SoC. It is similar to the 8MNANODLPD4-EVK eval board except it
has an IMX8MN UltraLite SoC and DDR3L memory. It esp. differs in the
PMIC configuration because the SoC has a smaller package and thus the
ARM core voltage is combined with the SoC voltage and the DDR voltage
is 1.35V for the DDR3L memory.

Drop Colibri V1.1 device tree, this is just a duplicate of Colibri V1.0
with the possibility to use SD cards in UHS mode if the carrier board
does not have 3.3V pull up resistor.
The dedicated device tree kept the feature switched of by setting
the no-1-8-v property and thus does not offer anything different
than what the regular device tree does.
Thus drop the dedicated device tree and merge the preparation to
allow enabling the feature should a carrier without pull ups
be used into the regular device tree.

Reuse the generic swiotlb initialization for xen-swiotlb. For ARM/ARM64
this works trivially, while for x86 xen_swiotlb_fixup needs to be passed
as the remap argument to swiotlb_init_remap/swiotlb_init_late.
Note that the lower bound of the swiotlb size is changed to the smaller
IO_TLB_MIN_SLABS based value with this patch, but that is fine as the
2MB value used in Xen before was just an optimization and is not the
hard lower bound.

It used to be that Linux enabled swiotlb-xen when running a dom0 on ARM.
Since f5079a9a2a31 "xen/arm: introduce XENFEAT_direct_mapped and
XENFEAT_not_direct_mapped", Linux detects whether to enable or disable
swiotlb-xen based on the new feature flags: XENFEAT_direct_mapped and
XENFEAT_not_direct_mapped.
However, there is still a leftover xen_initial_domain() check in
xen_create_contiguous_region. Remove the check as
xen_create_contiguous_region is only called by swiotlb-xen during
initialization. If xen_create_contiguous_region is called, we know Linux
is running 1:1 mapped so there is no need for additional checks.
Also update the in-code comment.

Commit 3ee48b6af49c ("mm, x86: Saving vmcore with non-lazy freeing of
vmas") introduced set_iounmap_nonlazy(), which sets vmap_lazy_nr to
lazy_max_pages() + 1, ensuring that any future vunmaps() immediately
purge the vmap areas instead of doing it lazily.
Commit 690467c81b1a ("mm/vmalloc: Move draining areas out of caller
context") moved the purging from the vunmap() caller to a worker thread.
Unfortunately, set_iounmap_nonlazy() can cause the worker thread to spin
(possibly forever). For example, consider the following scenario:
1. Thread reads from /proc/vmcore. This eventually calls
__copy_oldmem_page() -> set_iounmap_nonlazy(), which sets
vmap_lazy_nr to lazy_max_pages() + 1.
2. Then it calls free_vmap_area_noflush() (via iounmap()), which adds 2
pages (one page plus the guard page) to the purge list and
vmap_lazy_nr. vmap_lazy_nr is now lazy_max_pages() + 3, so the
drain_vmap_work is scheduled.
3. Thread returns from the kernel and is scheduled out.
4. Worker thread is scheduled in and calls drain_vmap_area_work(). It
frees the 2 pages on the purge list. vmap_lazy_nr is now
lazy_max_pages() + 1.
5. This is still over the threshold, so it tries to purge areas again,
but doesn't find anything.
6. Repeat 5.
If the system is running with only one CPU (which is typicial for kdump)
and preemption is disabled, then this will never make forward progress:
there aren't any more pages to purge, so it hangs. If there is more
than one CPU or preemption is enabled, then the worker thread will spin
forever in the background. (Note that if there were already pages to be
purged at the time that set_iounmap_nonlazy() was called, this bug is
avoided.)
This can be reproduced with anything that reads from /proc/vmcore
multiple times. E.g., vmcore-dmesg /proc/vmcore.
It turns out that improvements to vmap() over the years have obsoleted
the need for this "optimization". I benchmarked `dd if=/proc/vmcore
of=/dev/null` with 4k and 1M read sizes on a system with a 32GB vmcore.
The test was run on 5.17, 5.18-rc1 with a fix that avoided the hang, and
5.18-rc1 with set_iounmap_nonlazy() removed entirely:
|5.17 |5.18+fix|5.18+removal
4k|40.86s| 40.09s| 26.73s
1M|24.47s| 23.98s| 21.84s
The removal was the fastest (by a wide margin with 4k reads). This
patch removes set_iounmap_nonlazy().

CONFIG_NET_DSA_REALTEK and the desired DSA switch need
to be selected explicitly with
CONFIG_NET_DSA_REALTEK_RTL8366RB.
Take this opportunity to update some other minor config
options:
- CONFIG_MARVELL_PHY moved around because of Kconfig
changes.
- CONFIG_SENSORS_DRIVETEMP should be selected since is
regulates the system critical alert temperature on
some devices, which is nice if it is handled even

Boolean properties in DT are present or not present and don't take a value.
A property such as 'foo = <0>;' evaluated to true. IOW, the value doesn't
matter.
It may have been intended that 0 values are false, but there is no change
in behavior with this patch.

This adds the PN544 NFC chip mounted on some of the Codina models
numbered GT-I8160P. The "P" at the end of the product number
indicates that an NFC chip is mounted.

Pull s390 fixes from Heiko Carstens:
- Convert current_stack_pointer to a register alias like it is assumed
if ARCH_HAS_CURRENT_STACK_POINTER is selected. The existing
implementation as a function breaks CONFIG_HARDENED_USERCOPY
sanity-checks
- Get rid of -Warray-bounds warning within kexec code
- Add minimal IBM z16 support by reporting a proper elf platform, and
adding compile options
- Update defconfigs
* tag 's390-5.18-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
s390: enable CONFIG_HARDENED_USERCOPY in debug_defconfig
s390: current_stack_pointer shouldn't be a function
s390: update defconfigs
s390/kexec: silence -Warray-bounds warning
s390: allow to compile with z16 optimizations
s390: add z16 elf platform
