   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 
(https://github.com/linux-riscv/linux/pull/387/checks whose results can 
be seen here 
https://mazarinen.tail1c623.ts.net/riscv-linux/linux-all/build/riscv-fixes-6.15-rc6/).

----------------------------------------------------------------
RISC-V Fixes for 6.15-rc6

* The compressed half-word misaligned access instructions (c.lhu, c.lh,
  and c.sh) from the Zcb extension are now properly emulated.
* A series of fixes to properly emulate permissions while handling
  userspace misaligned accesses.
* A pair of fixes for PR_GET_TAGGED_ADDR_CTRL to avoid accessing the
  envcfg CSR on systems that don't support that CSR, and to report those
  failures up to userspace.
* The .rela.dyn section is no longer stripped from vmlinux, as it is
  necessary to relocate the kernel under some conditions (including
  kexec).

RISC-V Fixes for 6.15-rc6

* kCFI is restricted to clang-17 or newer, as earlier versions have
  known bugs.
* sbi_hsm_hart_start is now staticly allocated, to avoid tripping up the
  SBI HSM page mapping on sparse systems.
