Pull gpio updates from Bartosz Golaszewski:
"We have a single new driver, new features in others and some cleanups
all over the place.
Nothing really stands out and it is all relatively small.
- new driver: gpio-modepin (plus relevant change in zynqmp firmware)
- add interrupt support to gpio-virtio
- enable the 'gpio-line-names' property in the DT bindings for
gpio-rockchip
- use the subsystem helpers where applicable in gpio-uniphier instead
of accessing IRQ structures directly
- code shrink in gpio-xilinx
- add interrupt to gpio-mlxbf2 (and include the removal of custom
interrupt code from the mellanox ethernet driver)
- support multiple interrupts per bank in gpio-tegra186 (and force
one interrupt per bank in older models)
- fix GPIO line IRQ offset calculation in gpio-realtek-otto
- drop unneeded MODULE_ALIAS expansions in multiple drivers
- code cleanup in gpio-aggregator
- minor improvements in gpio-max730x and gpio-mc33880

Pull cxl updates from Dan Williams:
"More preparation and plumbing work in the CXL subsystem.
From an end user perspective the highlight here is lighting up the CXL
Persistent Memory related commands (label read / write) with the
generic ioctl() front-end in LIBNVDIMM.
Otherwise, the ability to instantiate new persistent and volatile
memory regions is still on track for v5.17.
Summary:
- Fix support for platforms that do not enumerate every ACPI0016 (CXL
Host Bridge) in the CHBS (ACPI Host Bridge Structure).
- Introduce a common pci_find_dvsec_capability() helper, clean up
open coded implementations in various drivers.
- Add 'cxl_test' for regression testing CXL subsystem ABIs.
'cxl_test' is a module built from tools/testing/cxl/ that mocks up
a CXL topology to augment the nascent support for emulation of CXL
devices in QEMU.
- Convert libnvdimm to use the uuid API.
- Complete the definition of CXL namespace labels in libnvdimm.
- Tunnel libnvdimm label operations from nd_ioctl() back to the CXL
mailbox driver. Enable 'ndctl {read,write}-labels' for CXL.
- Continue to sort and refactor functionality into distinct driver
and core-infrastructure buckets. For example, mailbox handling is
now a generic core capability consumed by the PCI and cxl_test
drivers"

The ACPI_HANDLE() macro is a wrapper arond the ACPI_COMPANION()
macro and the ACPI handle produced by the former comes from the
ACPI device object produced by the latter, so it is way more
straightforward to evaluate the latter directly instead of passing
the handle produced by the former to acpi_bus_get_device().
Modify i2c_amd_probe() accordingly (no intentional functional impact).

nr_free_buffer_pages could be exposed through mm.h instead of swap.h.
The advantage of this change is that it can reduce the obsolete
includes. For example, net/ipv4/tcp.c wouldn't need swap.h any more
since it has already included mm.h. Similarly, after checking all the
other files, it comes that tcp.c, udp.c meter.c ,... follow the same
rule, so these files can have swap.h removed too.
Moreover, after preprocessing all the files that use
nr_free_buffer_pages, it turns out that those files have already
included mm.h.Thus, we can move nr_free_buffer_pages from swap.h to mm.h
safely. This change will not affect the compilation of other files.

This change introduces an aged idle interface to the existing idle sysfs
file for zram.
When CONFIG_ZRAM_MEMORY_TRACKING is enabled the idle file now also
accepts an integer argument. This integer is the age (in seconds) of
pages to mark as idle. The idle file still supports 'all' as it always
has. This new approach allows for much more control over which pages
get marked as idle.

snprintf() returns the number of bytes it would have printed if there
were space. But it does not count the NUL terminator. So that means
that if "count == copied" then this has already overflowed by one
character.
This bug likely isn't super harmful in real life.

The read_from_bdev_async is not called on atomic context. So GFP_NOIO
is available rather than GFP_ATOMIC. If there were reclaimable pages
with GFP_NOIO, we can avoid allocation failure and page fault failure.

Patch series "memblock: cleanup memblock_free interface", v2.
This is the fix for memblock freeing APIs mismatch [1].
The first patch is a cleanup of numa_distance allocation in arch_numa
I've spotted during the conversion. The second patch is a fix for Xen
memory freeing on some of the error paths.
[1] https://lore.kernel.org/all/CAHk-=wj9k4LZTz+svCxLYs5Y1=+yKrbAUArH1+ghyG3OLd8VVg@mail.gmail.com
This patch (of 6):
Memory allocation of numa_distance uses memblock_phys_alloc_range()
without actual range limits, converts the returned physical address to
virtual and then only uses the virtual address for further
initialization.
Simplify this by replacing memblock_phys_alloc_range() with
memblock_alloc().

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.

Patch series "Add __alloc_size()", v3.
GCC and Clang both use the "alloc_size" attribute to assist with bounds
checking around the use of allocation functions. Add the attribute,
adjust the Makefile to silence needless warnings, and add the hints to
the allocators where possible. These changes have been in use for a
while now in GrapheneOS.
This patch (of 8):
After adding __alloc_size attributes to the allocators, GCC 9.3 (but not
later) may incorrectly evaluate the arguments to check_copy_size(),
getting seemingly confused by the size being returned from array_size().
Instead, perform the calculation once, which both makes the code more
readable and avoids the bug in GCC.
