Merge tag 's390-6.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull more s390 updates from Heiko Carstens:
- Add empty command line parameter handling stubs to kernel for all
command line parameters which are handled in the decompressor. This
avoids invalid "Unknown kernel command line parameters" messages from
the kernel, and also avoids that these will be incorrectly passed to
user space. This caused already confusion, therefore add the empty
stubs
- Add missing phys_to_virt() handling to machine check handler
- Introduce and use a union to be used for zcrypt inline assemblies.
This makes sure that only a register wide member of the union is
passed as input and output parameter to inline assemblies, while
usual C code uses other members of the union to access bit fields of
it
- Add and use a READ_ONCE_ALIGNED_128() macro, which can be used to
atomically read a 128-bit value from memory. This replaces the
(mis-)use of the 128-bit cmpxchg operation to do the same in cpum_sf
code. Currently gcc does not generate the used lpq instruction if
__READ_ONCE() is used for aligned 128-bit accesses, therefore use
this s390 specific helper
- Simplify machine check handler code if a task needs to be killed
because of e.g. register corruption due to a machine malfunction
- Perform CPU reset to clear pending interrupts and TLB entries on an
already stopped target CPU before delegating work to it
- Generate arch/s390/boot/vmlinux.map link map for the decompressor,
when CONFIG_VMLINUX_MAP is enabled for debugging purposes
- Fix segment type handling for dcssblk devices. It incorrectly always
returned type "READ/WRITE" even for read-only segements, which can
result in a kernel panic if somebody tries to write to a read-only
device
- Sort config S390 select list again
- Fix two kprobe reenter bugs revealed by a recently added kprobe kunit
test
