Nomap regions are treated as "reserved". When region boundaries are not
page aligned, we usually increase the "reserved" regions rather than
decrease them. So, we should use memblock_region_reserved_base_pfn()/
memblock_region_reserved_end_pfn() instead of memblock_region_memory_
base_pfn()/memblock_region_memory_base_pfn() to calculate boundaries.

As started by commit 05a5f51ca5 ("Documentation: Replace lkml.org links
with lore"), an effort was made to replace lkml.org links with lore to
better use a single source that's more likely to stay available long-term.
However, it seems these links don't offer much value here, so just
remove them entirely.

Commit e201260081 ("arm64: perf: Add userspace counter access disable
switch") introduced a new 'perf_user_access' sysctl file to enable and
disable direct userspace access to the PMU counters. Sadly, Geert
reports that on his big.LITTLE SoC ('Renesas Salvator-XS w/ R-Car H3'),
the file is created for each PMU type probed, resulting in a splat

Because of commit 9cb2ff1117 ("spi: cadence-quadspi: Disable Auto-HW polling"),
which does a write to the CQSPI_REG_WR_COMPLETION_CTRL register
regardless of any condition. Well, the Cadence QuadSPI controller on
Intel's SoCFPGA platforms does not implement the
CQSPI_REG_WR_COMPLETION_CTRL register, thus a write to this register
results in a crash!
So starting with v5.16, I introduced the patch
98d948eb83 ("spi: cadence-quadspi: fix write completion support"),
which adds the dts compatible "intel,socfpga-qspi" that is specific for
versions that doesn't have the CQSPI_REG_WR_COMPLETION_CTRL register implemented.

This is my last set of fixes for 5.16, including
- multiple code fixes for the op-tee firmware driver
- Two patches for allwinner SoCs, one fixing the phy mode on
a board, the other one fixing a driver bug in the "RSB"
bus driver. This was originally targetted for 5.17, but
seemed worth moving to 5.16.
- Two small fixes for devicetree files on i.MX platforms,
resolving problems with ethernet and i2c.

The erratum 1418040 workaround enables CNTVCT_EL1 access trapping in EL0
when executing compat threads. The workaround is applied when switching
between tasks, but the need for the workaround could also change at an
exec(), when a non-compat task execs a compat binary or vice versa. Apply
the workaround in arch_setup_new_exec().
This leaves a small window of time between SET_PERSONALITY and
arch_setup_new_exec where preemption could occur and confuse the old
workaround logic that compares TIF_32BIT between prev and next. Instead, we
can just read cntkctl to make sure it's in the state that the next task
needs. I measured cntkctl read time to be about the same as a mov from a
general-purpose register on N1. Update the workaround logic to examine the
current value of cntkctl instead of the previous task's compat state.

When facing a really early issue on DT parsing we have currently
a message that shows both the physical and virtual address of the FDT.
The printk pointer modifier for the virtual address shows a hashed
address there unless the user provides "no_hash_pointers" parameter in
the command-line. The situation in which this message shows-up is a bit
more serious though: the boot process is broken, nothing can be done
(even an oops is too much for this early stage) so we have this message
as a last resort in order to help debug bootloader issues, for example.
Hence, we hereby change that to "%px" in order to make debugging easy,
there's not much information leak risk in such early boot failure.
Also, we tried to improve a bit the commenting on that function, given
that if kernel fails there, it just hangs forever in a cpu_relax() loop.
The reason we cannot BUG/panic is that is too early to do so; thanks to
Mark Brown for pointing that on IRC and thanks Robin Murphy for the good
pointer hash discussion in the mailing-list.

For memory accesses with write-combining attributes (e.g. those returned
by ioremap_wc()), the CPU may wait for prior accesses to be merged with
subsequent ones. But in some situation, such wait is bad for the
performance.
We introduce io_stop_wc() to prevent the merging of write-combining
memory accesses before this macro with those after it.
We add implementation for ARM64 using DGH instruction and provide NOP
implementation for other architectures.

Some ARM64 Exynos SoCs have MCT timer block, e.g. Exynos850 and
Exynos5433. CLKSRC_EXYNOS_MCT option is not visible unless COMPILE_TEST
is enabled. Select CLKSRC_EXYNOS_MCT option for ARM64 ARCH_EXYNOS like
it's done in arch/arm/mach-exynos/Kconfig, to enable MCT timer support
for ARM64 Exynos SoCs.
Even though ARM architected timer is available on all ARM64 SoCs, and
used for managing timer hardware and clock source events, MCT timer
still can be used as a wakeup source, as stated in commitae460fd9164b
("clocksource/drivers/exynos_mct: Prioritise Arm arch timer on arm64").
It's also nice to be able to test available MCT IP-core.

CN9130 has a built-in CP115 which has 2 GPIO controllers, but unlike in
Armada 7k and 8k both are left disabled by the SoC DTSI.
This first of all makes no sense as they are always present due to being
SoC built-in and its an issue as boards like CN9130-CRB use the CPO GPIO2
pins for regulators and SD card support without enabling them first.
So, enable both of them like Armada 7k and 8k do.

CN9130 has one CP115 built in, which like the CP110 has 2 GPIO and 2 SPI
controllers built-in.
However, unlike the Armada 7k and 8k the SoC DTSI doesn't add the required
aliases as both the Orion SPI driver and MVEBU GPIO drivers require the
aliases to be present.
So add the required aliases for GPIO and SPI controllers.

Kernel driver phy-mvebu-a3700-comphy.c needs to know the rate of the
reference xtal clock. So add missing xtal clock source into comphy device
tree node. If the property is not present, the driver defaults to 25 MHz

: Series from Quentin Perret, implementing HYP page share/unshare:
:
: This series implements an unshare hypercall at EL2 in nVHE
: protected mode, and makes use of it to unmmap guest-specific
: data-structures from EL2 stage-1 during guest tear-down.
: Crucially, the implementation of the share and unshare
: routines use page refcounts in the host kernel to avoid
: accidentally unmapping data-structures that overlap a common
: page.
