Merge tag 's390-6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Alexander Gordeev:

- Store AP Query Configuration Information in a static buffer

- Rework the AP initialization and add missing cleanups to the error
path

- Swap IRQ and AP bus/device registration to avoid race conditions

- Export prot_virt_guest symbol

- Introduce AP configuration changes notifier interface to facilitate
modularization of the AP bus

- Add CONFIG_AP kernel configuration option to allow modularization of
the AP bus

- Rework CONFIG_ZCRYPT_DEBUG kernel configuration option description
and dependency and rename it to CONFIG_AP_DEBUG

- Convert sprintf() and snprintf() to sysfs_emit() in CIO code

- Adjust indentation of RELOCS command build step

- Make crypto performance counters upward compatible

- Convert make_page_secure() and gmap_make_secure() to use folio

- Rework channel-utilization-block (CUB) handling in preparation of
introducing additional CUBs

- Use attribute groups to simplify registration, removal and extension
of measurement-related channel-path sysfs attributes

- Add a per-channel-path binary "ext_measurement" sysfs attribute that
provides access to extended channel-path measurement data

- Export measurement data for all channel-measurement-groups (CMG), not
only for a specific ones. This enables support of new CMG data
formats in userspace without the need for kernel changes

- Add a per-channel-path sysfs attribute "speed_bps" that provides the
operating speed in bits per second or 0 if the operating speed is not
available

- The CIO tracepoint subchannel-type field "st" is incorrectly set to
the value of subchannel-enabled SCHIB "ena" field. Fix that

- Do not forcefully limit vmemmap starting address to MAX_PHYSMEM_BITS

- Consider the maximum physical address available to a DCSS segment
(512GB) when memory layout is set up

- Simplify the virtual memory layout setup by reducing the size of
identity mapping vs vmemmap overlap

- Swap vmalloc and Lowcore/Real Memory Copy areas in virtual memory.
This will allow to place the kernel image next to kernel modules

- Move everyting KASLR related from <asm/setup.h> to <asm/page.h>

- Put virtual memory layout information into a structure to improve
code generation

- Currently __kaslr_offset is the kernel offset in both physical and
virtual memory spaces. Uncouple these offsets to allow uncoupling of
the addresses spaces

- Currently the identity mapping base address is implicit and is always
set to zero. Make it explicit by putting into __identity_base
persistent boot variable and use it in proper context

- Introduce .amode31 section start and end macros AMODE31_START and
AMODE31_END

- Introduce OS_INFO entries that do not reference any data in memory,
but rather provide only values

- Store virtual memory layout in OS_INFO. It is read out by
makedumpfile, crash and other tools

- Store virtual memory layout in VMCORE_INFO. It is read out by crash
and other tools when /proc/kcore device is used

- Create additional PT_LOAD ELF program header that covers kernel image
only, so that vmcore tools could locate kernel text and data when
virtual and physical memory spaces are uncoupled

- Uncouple physical and virtual address spaces

- Map kernel at fixed location when KASLR mode is disabled. The
location is defined by CONFIG_KERNEL_IMAGE_BASE kernel configuration
value.

- Rework deployment of kernel image for both compressed and
uncompressed variants as defined by CONFIG_KERNEL_UNCOMPRESSED kernel
configuration value

- Move .vmlinux.relocs section in front of the compressed kernel. The
interim section rescue step is avoided as result

- Correct modules thunk offset calculation when branch target is more
than 2GB away

- Kernel modules contain their own set of expoline thunks. Now that the
kernel modules area is less than 4GB away from kernel expoline
thunks, make modules use kernel expolines. Also make EXPOLINE_EXTERN
the default if the compiler supports it

- userfaultfd can insert shared zeropages into processes running VMs,
but that is not allowed for s390. Fallback to allocating a fresh
zeroed anonymous folio and insert that instead

- Re-enable shared zeropages for non-PV and non-skeys KVM guests

- Rename hex2bitmap() to ap_hex2bitmap() and export it for external use

- Add ap_config sysfs attribute to provide the means for setting or
displaying adapters, domains and control domains assigned to a
vfio-ap mediated device in a single operation

- Make vfio_ap_mdev_link_queue() ignore duplicate link requests

- Add write support to ap_config sysfs attribute to allow atomic update
a vfio-ap mediated device state

- Document ap_config sysfs attribute

- Function os_info_old_init() is expected to be called only from a
regular kdump kernel. Enable it to be called from a stand-alone dump
kernel

- Address gcc -Warray-bounds warning and fix array size in struct
os_info

- s390 does not support SMBIOS, so drop unneeded CONFIG_DMI checks

- Use unwinder instead of __builtin_return_address() with ftrace to
prevent returning of undefined values

- Sections .hash and .gnu.hash are only created when CONFIG_PIE_BUILD
kernel is enabled. Drop these for the case CONFIG_PIE_BUILD is
disabled

- Compile kernel with -fPIC and link with -no-pie to allow kpatch
feature always succeed and drop the whole CONFIG_PIE_BUILD
option-enabled code

- Add missing virt_to_phys() converter for VSIE facility and crypto
control blocks

s390/vfio-ap: Add write support to sysfs attr ap_config

Allow writing a complete set of masks to ap_config. Doing so will
cause the vfio-ap driver to replace the vfio-ap mediated device's
matrix masks with the given set of masks. If the given state cannot
be set, then no changes are made to the vfio-ap mediated device.

The format of the data written to ap_config is as follows:
{amask},{dmask},{cmask}\n

\n is a newline character.

amask, dmask, and cmask are masks identifying which adapters, domains,
and control domains should be assigned to the mediated device.

The format of a mask is as follows:
0xNN..NN

Where NN..NN is 64 hexadecimal characters representing a 256-bit value.
The leftmost (highest order) bit represents adapter/domain 0.

For an example set of masks that represent your mdev's current
configuration, simply cat ap_config.

This attribute is intended to be used by an mdevctl callout script
supporting the mdev type vfio_ap-passthrough to atomically update a
vfio-ap mediated device's state.
