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

Merge tag 's390-6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:

- Large cleanup of the con3270/tty3270 driver. Among others this fixes:
- Background Color Support
- ASCII Line Character Support
- VT100 Support
- Geometries other than 80x24

- Cleanup and improve cmpxchg() code. Also add cmpxchg_user_key() to
uaccess functions, which will be used by KVM to access KVM guest
memory with a specific storage key

- Add support for user space events counting to CPUMF

- Cleanup the vfio/ccw code, which also allows now to properly support
2K Format-2 IDALs

- Move kernel page table allocation and initialization to decompressor,
which finally allows to enter the kernel with dynamic address
translation enabled. This in turn allows to get rid of code with
special handling in the kernel, which has to distinguish if DAT is on
or off

- Replace kretprobe with rethook

- Various improvements to vfio/ap queue resets:
- Use TAPQ to verify completion of a reset in progress rather than
multiple invocations of ZAPQ.
- Check TAPQ response codes when verifying successful completion of
ZAPQ.
- Fix erroneous handling of some error response codes.
- Increase the maximum amount of time to wait for successful
completion of ZAPQ

- Rework system call wrappers to get rid of alias functions, which were
only left on s390

- Cleanup diag288_wdt watchdog driver. It has been agreed on with
Guenter Roeck that this goes upstream via the s390 tree

- Add missing loadparm parameter handling for list-directed ECKD
ipl/reipl

- Various improvements to memory detection code

- Remove arch_cpu_idle_time() since the current implementation is
broken, and allows user space observable accounted idle times which
can temporarily decrease

- Add Reset DAT-Protection support: (only) allow to change PTEs from RO
to RW with a new RDP instruction. Unlike the currently used IPTE
instruction, this does not necessarily guarantee that TLBs of all
CPUs are synchronously flushed; and that remote CPUs can see spurious
protection faults. The overall improvement for not requiring an all
CPU synchronization, like it is required with IPTE, should be
beneficial

- Fix KFENCE page fault reporting

- Smaller cleanups and improvement all over the place

s390/3270: unify con3270 + tty3270

There were two flavours of 3270 drivers: con3270, which provides a
console driver, and tty3270 providing a tty driver. A user could switch
with PF3 between the two views. While this sounds nice, it's a bit
annoying: If the user enters a command which triggers a kernel message,
he always has to switch back and forth to see the message. Unify both
views to have kernel messages and tty in one screen, like it is on almost
all other platforms. This also has the nice side effect of removing a lot
of duplicate code.
