   riscv: Disallow PR_GET_TAGGED_ADDR_CTRL without Supm (2025-05-08 
12:01:01 +0000)

----------------------------------------------------------------
riscv fixes for 6.15-rc6

- A fix to handle compressed halfword load/store instructions misaligned 
accesses
- A fix to allow user memory access while handling a misaligned access
- 2 fixes to return an error if the pointer masking extension is not 
implemented on the platform but userspace still tries to access it, 
which caused oops on some early platforms
- A fix to prevent the stripping of .rela.dyn so that a vmlinux loaded 
by kexec can successfully boot

----------------------------------------------------------------

All the patches have been tested on our github CI and no regressions 
were found against 6.15-rc5
