We currently walk the hypervisor stage-1 page-table towards the end of
hyp init in nVHE protected mode and adjust the host page ownership
attributes in its stage-2 in order to get a consistent state from both
point of views. The walk is done on the entire hyp VA space, and expects
to only ever find page-level mappings. While this expectation is
reasonable in the half of hyp VA space that maps memory with a fixed
offset (see the loop in pkvm_create_mappings_locked()), it can be
incorrect in the other half where nothing prevents the usage of block
mappings. For instance, on systems where memory is physically aligned at
an address that happens to maps to a PMD aligned VA in the hyp_vmemmap,
kvm_pgtable_hyp_map() will install block mappings when backing the
hyp_vmemmap, which will later cause finalize_host_mappings() to fail.
Furthermore, it should be noted that all pages backing the hyp_vmemmap
are also mapped in the 'fixed offset range' of the hypervisor, which
implies that finalize_host_mappings() will walk both aliases and update
the host stage-2 attributes twice. The order in which this happens is
unpredictable, though, since the hyp VA layout is highly dependent on
the position of the idmap page, hence resulting in a fragile mess at
best.
In order to fix all of this, let's restrict the finalization walk to
only cover memory regions in the 'fixed-offset range' of the hyp VA
space and nothing else. This not only fixes a correctness issue, but
will also result in a slighlty faster hyp initialization overall.

Since ARMv8.0 the upper 32 bits of ESR_ELx have been RES0, and recently
some of the upper bits gained a meaning and can be non-zero. For
example, when FEAT_LS64 is implemented, ESR_ELx[36:32] contain ISS2,
which for an ST64BV or ST64BV0 can be non-zero. This can be seen in ARM
DDI 0487G.b, page D13-3145, section D13.2.37.
Generally, we must not rely on RES0 bit remaining zero in future, and
when extracting ESR_ELx.EC we must mask out all other bits.
All C code uses the ESR_ELx_EC() macro, which masks out the irrelevant
bits, and therefore no alterations are required to C code to avoid
consuming irrelevant bits.
In a couple of places the KVM assembly extracts ESR_ELx.EC using LSR on
an X register, and so could in theory consume previously RES0 bits. In
both cases this is for comparison with EC values ESR_ELx_EC_HVC32 and
ESR_ELx_EC_HVC64, for which the upper bits of ESR_ELx must currently be
zero, but this could change in future.
This patch adjusts the KVM vectors to use UBFX rather than LSR to
extract ESR_ELx.EC, ensuring these are robust to future additions to
ESR_ELx.

I have no idea why this never showed up earlier, but the safest

After switched page size from 64KB to 4KB on several arm64 servers here,
kmemleak starts to run out of early memory pool due to a huge number of
those early_pgtable_alloc() calls:
kmemleak_alloc_phys()
memblock_alloc_range_nid()
memblock_phys_alloc_range()
early_pgtable_alloc()
init_pmd()
alloc_init_pud()
__create_pgd_mapping()
__map_memblock()
paging_init()
setup_arch()
start_kernel()
Increased the default value of DEBUG_KMEMLEAK_MEM_POOL_SIZE by 4 times
won't be enough for a server with 200GB+ memory. There isn't much
interesting to check memory leaks for those early page tables and those
early memory mappings should not reference to other memory. Hence, no
kmemleak false positives, and we can safely skip tracking those early
allocations from kmemleak like we did in the commit fed84c785270
("mm/memblock.c: skip kmemleak for kasan_init()") without needing to
introduce complications to automatically scale the value depends on the
runtime memory size etc. After the patch, the default value of
DEBUG_KMEMLEAK_MEM_POOL_SIZE becomes sufficient again.

The -nostdlib option requests the compiler to not use the standard
system startup files or libraries when linking. It is effective only
when $(CC) is used as a linker driver.
Since commit 691efbedc60d ("arm64: vdso: use $(LD) instead of $(CC)
to link VDSO"), $(LD) is directly used, hence -nostdlib is unneeded.

The id argument of ARM64_FTR_REG_OVERRIDE() is used for two purposes:
one as the system register encoding (used for the sys_id field of
__ftr_reg_entry), and the other as the register name (stringified
and used for the name field of arm64_ftr_reg), which is debug
information. The id argument is supposed to be a macro that
indicates an encoding of the register (eg. SYS_ID_AA64PFR0_EL1, etc).
ARM64_FTR_REG(), which also has the same id argument,
uses ARM64_FTR_REG_OVERRIDE() and passes the id to the macro.
Since the id argument is completely macro-expanded before it is
substituted into a macro body of ARM64_FTR_REG_OVERRIDE(),
the stringified id in the body of ARM64_FTR_REG_OVERRIDE is not
a human-readable register name, but a string of numeric bitwise
operations.
Fix this so that human-readable register names are available as
debug information.

Put the definitions of the hypercalls usable only by pv guests inside
CONFIG_XEN_PV sections.
On Arm two dummy functions related to pv hypercalls can be removed.
While at it remove the no longer supported tmem hypercall definition.

Documentation/kbuild/makefiles.rst suggests to use "archclean" for
cleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement.
Since commit d92cc4d51643 ("kbuild: require all architectures to have
arch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick for
all architectures. This can take advantage of the parallel option (-j)
for "make clean".
I also cleaned up the comments in arch/$(SRCARCH)/Makefile. The "archdep"
target no longer exists.

Further isolate kernel from userspace, prevent accidental inclusion of
undesireable headers, mainly float.h and stdatomic.h.
nds32 keeps -isystem globally due to intrinsics used in entrenched header.
-isystem is selectively reenabled for some files, again, for intrinsics.

Since memblock_free() operates on a physical range, make its name
reflect it and rename it to memblock_phys_free(), so it will be a
logical counterpart to memblock_phys_alloc().
The callers are updated with the below semantic patch:
@@
expression addr;
expression size;
@@
- memblock_free(addr, size);
+ memblock_phys_free(addr, size);

Percpu embedded first chunk allocator is the firstly option, but it
could fails on ARM64, eg,
percpu: max_distance=0x5fcfdc640000 too large for vmalloc space 0x781fefff0000
percpu: max_distance=0x600000540000 too large for vmalloc space 0x7dffb7ff0000
percpu: max_distance=0x5fff9adb0000 too large for vmalloc space 0x5dffb7ff0000
then we could get
WARNING: CPU: 15 PID: 461 at vmalloc.c:3087 pcpu_get_vm_areas+0x488/0x838
and the system could not boot successfully.
Let's implement page mapping percpu first chunk allocator as a fallback
to the embedding allocator to increase the robustness of the system.

Coresight changes for v5.16
- A new option to make coresight cpu-debug capabilities available as early
as possible in the kernel boot process.
- Make trace sessions more enduring by coping with scenarios where events
are scheduled on CPUs that can't reach the selected sink.
- A set of improvement to make the TMC-ETR driver more efficient.
- Enhancements to the TRBE driver to correct several errata.
- An enhancement to make the AXI burts size configurable for TMC devices
that can't work with the default value.
- A fix in the CTI module to use the correct device when calling
pm_runtime_put()
- The addition of the Kryo-5xx device to the list of support ETMs.

Qualcomm ARM64 defconfig updates for v5.16
The major change here is the disabling of the firmware loades user space
fallback, this is done as arm64 is the only platform with this flag
enabled and as a result doesn't play nice with standard distributions.
It then enables the new limits driver, which controls the hardware based
thermal mitigation on a range of Qualcomm platforms. The prima/pronto
WiFi and Bluetooth drivers are enabled to ensure these features works
out of the box, now that the last details in the dts are landed.
The new driver for acquiring sleep stats is enabled to facilitate the
various efforts on getting these platforms into low power mode.
Lastly the base SC7280 drivers needed to simply boot this platform are
enabled.

With the introduction of LMH in '36c6581214c4 ("arm64: dts: qcom:
sdm845: Add support for LMh node")' the CPUfreq gained a reference for
the two interrupts from the LMh. This means that if the LMh driver isn't
enabled CPUfreq will not probe and there's no frequency scaling.
Enable LMh to make CPUfreq functional again on SDM845.

Part of the enablement of SDMA on the IMX platforms, '7f4e4afa140c
("arm64: defconfig: Enable SDMA on i.mx8mq/8mm")' also enabled
CONFIG_FW_LOADER_USER_HELPER_FALLBACK, to allow "firmware loaded by
udev".
Unfortunately having the fallback enabled does, due to the 60 second
timeout, essentially requiring userspace to provide a firmware loader.
But systemd dropped the support for this interface back in 2014 and
because arm64 is the only architecture that has this enabled, there
doesn't seem to be any standard solution available.
Examples of this problem can be found in e.g. the ath10k driver, which
with a standard distro can take about 10 minutes before wlan0 appears.
The alternative to this patch would be to change these drivers to use
firmware_request_direct(), to avoid the sysfs fallback. But that would
prevent other systems, such as Android, to rely on a userspace firmware
loader to pick the firmware from a non-standard place, with just a
custom defconfig.
This patch therefor attempts to align the arm64 defconfig will all other
architectures in the upstream kernel.
