Merge branch 'for-6.2/apple' into for-linus

- new quirks for select Apple keyboards (Kerem Karabay, Aditya Garg)


# 47477c84 12-Dec-2022 Linus Torvalds <torvalds@linux-foundation.org>

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

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()

s390/debug: remove function type cast

clang warns about an incompatible function type cast:

CC arch/s390/kernel/debug.o
arch/s390/kernel/debug.c:142:2: error: cast from 'int (*)(debug_info_t *, struct debug_view *, char *, debug_sprintf_entry_t *)' (aka 'int (*)(struct debug_info *, struct debug_view *, char *, debug_sprintf_entry_t *)') to 'debug_format_proc_t *' (aka 'int (*)(struct debug_info *, struct debug_view *, char *, const char *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
(debug_format_proc_t *)&debug_sprintf_format_fn,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Get rid of this warning by changing debug_sprintf_format_fn() so it matches
the debug_format_proc_t function type, and do the cast of the last
parameter within the function itself.
This is the standard way of handling such cases anyway.
