Merge tag 's390-6.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Alexander Gordeev:

- Standardize on the __ASSEMBLER__ macro that is provided by GCC and
Clang compilers and replace __ASSEMBLY__ with __ASSEMBLER__ in both
uapi and non-uapi headers

- Explicitly include <linux/export.h> in architecture and driver files
which contain an EXPORT_SYMBOL() and remove the include from the
files which do not contain the EXPORT_SYMBOL()

- Use the full title of "z/Architecture Principles of Operation" manual
and the name of a section where facility bits are listed

- Use -D__DISABLE_EXPORTS for files in arch/s390/boot to avoid
unnecessary slowing down of the build and confusing external kABI
tools that process symtypes data

- Print additional unrecoverable machine check information to make the
root cause analysis easier

- Move cmpxchg_user_key() handling to uaccess library code, since the
generated code is large anyway and there is no benefit if it is
inlined

- Fix a problem when cmpxchg_user_key() is executing a code with a
non-default key: if a system is IPL-ed with "LOAD NORMAL", and the
previous system used storage keys where the fetch-protection bit was
set for some pages, and the cmpxchg_user_key() is located within such
page, a protection exception happens

- Either the external call or emergency signal order is used to send an
IPI to a remote CPU. Use the external order only, since it is at
least as good and sometimes even better, than the emergency signal

- In case of an early crash the early program check handler prints more
or less random value of the last breaking event address, since it is
not initialized properly. Copy the last breaking event address from
the lowcore to pt_regs to address this

- During STP synchronization check udelay() can not be used, since the
first CPU modifies tod_clock_base and get_tod_clock_monotonic() might
return a non-monotonic time. Instead, busy-loop on other CPUs, while
the the first CPU actually handles the synchronization operation

- When debugging the early kernel boot using QEMU with the -S flag and
GDB attached, skip the decompressor and start directly in kernel

- Rename PAI Crypto event 4210 according to z16 and z17 "z/Architecture
Principles of Operation" manual

- Remove the in-kernel time steering support in favour of the new s390
PTP driver, which allows the kernel clock steered more precisely

- Remove a possible false-positive warning in pte_free_defer(), which
could be triggered in a valid case KVM guest process is initializing

s390/boot: Introduce jump_to_kernel() function

Introduce a global function that jumps from the decompressor to the
decompressed kernel. Put its address into svc_old_psw, from where GDB
can take it without loading decompressor symbols. It should be
available throughout the entire decompressor execution, because it's
placed there statically, and nothing in the decompressor uses the SVC
instruction.

Merge tag 's390-5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:

- Make use of the IBM z16 processor activity instrumentation facility
to count cryptography operations: add a new PMU device driver so that
perf can make use of this.

- Add new IBM z16 extended counter set to cpumf support.

- Add vdso randomization support.

- Add missing KCSAN instrumentation to barriers and spinlocks, which
should make s390's KCSAN support complete.

- Add support for IPL-complete-control facility: notify the hypervisor
that kexec finished work and the kernel starts.

- Improve error logging for PCI.

- Various small changes to workaround llvm's integrated assembler
limitations, and one bug, to make it finally possible to compile the
kernel with llvm's integrated assembler. This also requires to raise
the minimum clang version to 14.0.0.

- Various other small enhancements, bug fixes, and cleanups all over
the place.
