Linus Torvalds a452483508 s390 updates for 6.5 merge window part 2
- Fix virtual vs physical address confusion in vmem_add_range()
   and vmem_remove_range() functions.
 
 - Include <linux/io.h> instead of <asm/io.h> and <asm-generic/io.h>
   throughout s390 code.
 
 - Make all PSW related defines also available for assembler files.
   Remove PSW_DEFAULT_KEY define from uapi for that.
 
 - When adding an undefined symbol the build still succeeds, but
   userspace crashes trying to execute VDSO, because the symbol
   is not resolved. Add undefined symbols check to prevent that.
 
 - Use kvmalloc_array() instead of kzalloc() for allocaton of 256k
   memory when executing s390 crypto adapter IOCTL.
 
 - Add -fPIE flag to prevent decompressor misaligned symbol build
   error with clang.
 
 - Use .balign instead of .align everywhere. This is a no-op for s390,
   but with this there no mix in using .align and .balign anymore.
 
 - Filter out -mno-pic-data-is-text-relative flag when compiling
   kernel to prevent VDSO build error.
 
 - Rework entering of DAT-on mode on CPU restart to use PSW_KERNEL_BITS
   mask directly.
 
 - Do not retry administrative requests to some s390 crypto cards,
   since the firmware assumes replay attacks.
 
 - Remove most of the debug code, which is build in when kernel config
   option CONFIG_ZCRYPT_DEBUG is enabled.
 
 - Remove CONFIG_ZCRYPT_MULTIDEVNODES kernel config option and switch
   off the multiple devices support for the s390 zcrypt device driver.
 
 - With the conversion to generic entry machine checks are accounted
   to the current context instead of irq time. As result, the STCKF
   instruction at the beginning of the machine check handler and the
   lowcore member are no longer required, therefore remove it.
 
 - Fix various typos found with codespell.
 
 - Minor cleanups to CPU-measurement Counter and Sampling Facilities code.
 
 - Revert patch that removes VMEM_MAX_PHYS macro, since it causes
   a regression.
