Merge tag 'sparc-for-6.18-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/alarsson/linux-sparc

Pull sparc updates from Andreas Larsson:

 - Add relocation handling for R_SPARC_UA64 for sparc64 that is
   generated by llvm and clarify printout on missing relocation handler

 - Fix missing hugetlb tte initialization for sun4u

 - Code cleanup for redundant use of __GPF_NOWARN for sparc64

 - Fix prototypes of reads[bwl]() for sparc64 by adding missing const
   and volatile pointer qualifiers

 - Fix bugs in accurate exception reporting in multiple machine specific
   sparc64 variants of copy_{from,to}_user() for sparc64

 - Fix memory leak in error handling for sparc32

 - Drop -ansi from asflags and replace __ASSEMBLY__ with __ASSEMBLER__
   in headers for all arch/sparc

 - Replace strcpy() with strscpy() for all arch/sparc
