Merge tag 's390-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Alexander Gordeev:

 - Factor out handle_write() function and simplify 3215 console write
   operation

 - When 3170 terminal emulator is connected to the 3215 console driver
   the boot time could be very long due to limited buffer space or
   missing operator input. Add con3215_drop command line parameter and
   con3215_drop sysfs attribute file to instruct the kernel drop console
   data when such conditions are met

 - Fix white space errors in 3215 console driver

 - Move enum paiext_mode definition to a header file and rename it to
   paievt_mode to indicate this is now used for several events. Rename
   PAI_MODE_COUNTER to PAI_MODE_COUNTING to make consistent with
   PAI_MODE_SAMPLING

 - Simplify the logic of PMU pai_crypto mapped buffer reference counter
   and make it consistent with PMU pai_ext

 - Rename PMU pai_crypto mapped buffer structure member users to
   active_events to make it consistent with PMU pai_ext

 - Enable HUGETLB_PAGE_OPTIMIZE_VMEMMAP configuration option. This
   results in saving of 12K per 1M hugetlb page (~1.2%) and 32764K per
   2G hugetlb page (~1.6%)

 - Use generic serial.h, bugs.h, shmparam.h and vga.h header files and
   scrap s390-specific versions

 - The generic percpu setup code does not expect the s390-like
   implementation and emits a warning. To get rid of that warning and
   provide sane CPU-to-node and CPU-to-CPU distance mappings implementat
   a minimal version of setup_per_cpu_areas()

 - Use kstrtobool() instead of strtobool() for re-IPL sysfs device
   attributes

 - Avoid unnecessary lookup of a pointer to MSI descriptor when setting
   IRQ affinity for a PCI device

 - Get rid of "an incompatible function type cast" warning by changing
   debug_sprintf_format_fn() function prototype so it matches the
   debug_format_proc_t function type

 - Remove unused info_blk_hdr__pcpus() and get_page_state() functions

 - Get rid of clang "unused unused insn cache ops function" warning by
   moving s390_insn definition to a private header

 - Get rid of clang "unused function" warning by making function
   raw3270_state_final() only available if CONFIG_TN3270_CONSOLE is
   enabled

 - Use kstrobool() to parse sclp_con_drop parameter to make it identical
   to the con3215_drop parameter and allow passing values like "yes" and
   "true"

 - Use sysfs_emit() for all SCLP sysfs show functions, which is the
   current standard way to generate output strings

 - Make SCLP con_drop sysfs attribute also writable and allow to change
   its value during runtime. This makes SCLP console drop handling
   consistent with the 3215 device driver

 - Virtual and physical addresses are indentical on s390. However, there
   is still a confusion when pointers are directly casted to physical
   addresses or vice versa. Use correct address converters
   virt_to_phys() and phys_to_virt() for s390 channel IO drivers

 - Support for power managemant has been removed from s390 since quite
   some time. Remove unused power managemant code from the appldata
   device driver

 - Allow memory tools like KASAN see memory accesses from the checksum
   code. Switch to GENERIC_CSUM if KASAN is enabled, just like x86 does

 - Add support of ECKD DASDs disks so it could be used as boot and dump
   devices

 - Follow checkpatch recommendations and use octal values instead of
   S_IRUGO and S_IWUSR for dump device attributes in sysfs

 - Changes to vx-insn.h do not cause a recompile of C files that use
   asm(".include \"asm/vx-insn.h\"\n") magic to access vector
   instruction macros from inline assemblies. Add wrapper include header
   file to avoid this problem

 - Use vector instruction macros instead of byte patterns to increase
   register validation routine readability

 - The current machine check register validation handling does not take
   into account various scenarios and might lead to killing a wrong user
   process or potentially ignore corrupted FPU registers. Simplify logic
   of the machine check handler and stop the whole machine if the
   previous context was kerenel mode. If the previous context was user
   mode, kill the current task

 - Introduce sclp_emergency_printk() function which can be used to emit
   a message in emergency cases. It is supposed to be used in cases
   where regular console device drivers may not work anymore, e.g.
   unrecoverable machine checks

   Keep the early Service-Call Control Block so it can also be used
   after initdata has been freed to allow sclp_emergency_printk()
   implementation

 - In case a system will be stopped because of an unrecoverable machine
   check error print the machine check interruption code to give a hint
   of what went wrong

 - Move storage error checking from the assembly entry code to C in
   order to simplify machine check handling. Enter the handler with DAT
   turned on, which simplifies the entry code even more

 - The machine check extended save areas are allocated using a private
   "nmi_save_areas" slab cache which guarantees a required power-of-two
   alignment. Get rid of that cache in favour of kmalloc()
