s390/mm: make virt_to_pfn() a static inline
Making virt_to_pfn() a static inline taking a strongly typed (const void *) makes the contract of a passing a pointer of that type to the function explicit and exposes any misuse of the macro virt_to_pfn() acting polymorphic and accepting many types such as (void *), (unitptr_t) or (unsigned long) as arguments without warnings.
For symmetry do the same with pfn_to_virt() reflecting the current layout in asm-generic/page.h.
Doing this reveals a number of offenders in the arch code and the S390-specific drivers, so just bite the bullet and fix up all of those as well.

diag10_range() expects a pfn, however the current cmm code is shifting a virtual address, instead of a physical address by PAGE_SHIFT bits, which would give a wrong result in case if V!=R.
Use virt_to_pfn() to fix this.
Note: this currently doesn't fix a real bug, since virtual addresses are indentical to physical ones.

mm: remove unneeded includes of <asm/pgalloc.h>
Patch series "mm: cleanup usage of <asm/pgalloc.h>"
Most architectures have very similar versions of pXd_alloc_one() and pXd_free_one() for intermediate levels of page table. These patches add generic versions of these functions in <asm-generic/pgalloc.h> and enable use of the generic functions where appropriate.
In addition, functions declared and defined in <asm/pgalloc.h> headers are used mostly by core mm and early mm initialization in arch and there is no actual reason to have the <asm/pgalloc.h> included all over the place. The first patch in this series removes unneeded includes of <asm/pgalloc.h>
In the end it didn't work out as neatly as I hoped and moving pXd_alloc_track() definitions to <asm-generic/pgalloc.h> would require unnecessary changes to arches that have custom page table allocations, so I've decided to move lib/ioremap.c to mm/ and make pgalloc-track.h local to mm/.
This patch (of 8):
In most cases <asm/pgalloc.h> header is required only for allocations of page table memory. Most of the .c files that include that header do not use symbols declared in <asm/pgalloc.h> and do not require that header.
As for the other header files that used to include <asm/pgalloc.h>, it is possible to move that include into the .c file that actually uses symbols from <asm/pgalloc.h> and drop the include from the header file.
The process was somewhat automated using
sed -i -E '/[<"]asm\/pgalloc\.h/d' \ $(grep -L -w -f /tmp/xx \ $(git grep -E -l '[<"]asm/pgalloc\.h'))
where /tmp/xx contains all the symbols defined in arch/*/include/asm/pgalloc.h.

Instead of having all the sysctl handlers deal with user pointers, which is rather hairy in terms of the BPF interaction, copy the input to and from userspace in common code. This also means that the strings are always NUL-terminated by the common code, making the API a little bit safer.
As most handler just pass through the data to one of the common handlers a lot of the changes are mechnical.

To avoid potential race condition and hitting BUG_ON in add_timer on already pending timer simply reuse mod_timer which is according to documentation "the only safe way to modify the timeout" with multiple unserialized concurrent users. mod_timer can handle both active and inactive timers which allows to carry out minor code simplification as well.

Update the arch/s390/mm/ files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.

s390: mm: Audit and remove any unnecessary uses of module.h
Historically a lot of these existed because we did not have a distinction between what was modular code and what was providing support to modules via EXPORT_SYMBOL and friends. That changed when we forked out support for the latter into the export.h file.
This means we should be able to reduce the usage of module.h in code that is obj-y Makefile or bool Kconfig. The advantage in doing so is that module.h itself sources about 15 other headers; adding significantly to what we feed cpp, and it can obscure what headers we are effectively using.
Since module.h was the source for init.h (for __init) and for export.h (for EXPORT_SYMBOL) we consider each change instance for the presence of either and replace as needed. An instance where module_param was used without moduleparam.h was also fixed, as well as an implict use of asm/elf.h header.

s390/comments: unify copyright messages and remove file names
Remove the file name from the comment at top of many files. In most cases the file name was wrong anyway, so it's rather pointless.
Also unify the IBM copyright statement. We did have a lot of sightly different statements and wanted to change them one after another whenever a file gets touched. However that never happened. Instead people start to take the old/"wrong" statements to use as a template for new files. So unify all of them in one go.

[S390] replace diag10() with diag10_range() function
Currently the diag10() function can only release one page. For exploiters that have to call diag10 on a contiguous memory region this is suboptimal. This patch replaces the diag10() function with diag10_range() that is able to release multiple pages. In addition to that the new function now allows to release memory with addresses higher than 2047 MiB. This was due to a restriction of the diagnose implementation under z/VM prior to release 5.2.
