Linus Torvalds 2a4c0c11c0 s390 updates for 7.1 merge window
- Add support for CONFIG_PAGE_TABLE_CHECK and enable it in
   debug_defconfig. s390 can only tell user from kernel PTEs via the mm,
   so mm_struct is now passed into pxx_user_accessible_page() callbacks
 
 - Expose the PCI function UID as an arch-specific slot attribute in
   sysfs so a function can be identified by its user-defined id while
   still in standby. Introduces a generic ARCH_PCI_SLOT_GROUPS hook in
   drivers/pci/slot.c
 
 - Refresh s390 PCI documentation to reflect current behavior and cover
   previously undocumented sysfs attributes
 
 - zcrypt device driver cleanup series: consistent field types, clearer
   variable naming, a kernel-doc warning fix, and a comment explaining
   the intentional synchronize_rcu() in pkey_handler_register()
 
 - Provide an s390 arch_raw_cpu_ptr() that avoids the detour via
   get_lowcore() using alternatives, shrinking defconfig by ~27 kB
 
 - Guard identity-base randomization with kaslr_enabled() so nokaslr
   keeps the identity mapping at 0 even with
   CONFIG_RANDOMIZE_IDENTITY_BASE=y
 
 - Build S390_MODULES_SANITY_TEST as a module only by requiring
   KUNIT && m, since built-in would not exercise module loading
 
 - Remove the permanently commented-out HMCDRV_DEV_CLASS create_class()
   code in the hmcdrv driver
 
 - Drop stale ident_map_size extern conflicting with asm/page.h
