Linus Torvalds 03de3e44a7 RISC-V updates for v6.19-rc3
- Add probing and userspace reporting support for the standard RISC-V
   ISA extensions Zilsd and Zclsd, which implement load/store dual
   instructions on RV32
 
 - Abstract the register saving code in setup_sigcontext() so it can be
   used for stateful RISC-V ISA extensions beyond the vector extension
 
 - Add the SBI extension ID and some initial data structure definitions
   for the RISC-V standard SBI debug trigger extension
 
 - Clean up some code slightly: change some page table functions to
   avoid atomic operations oinn !SMP and to avoid unnecessary casts to
   atomic_long_t; and use the existing RISCV_FULL_BARRIER macro in
   place of some open-coded "fence rw,rw" instructions

 "Nothing exotic here; these are the cleanup and new ISA extension
  probing patches (not including CFI):

   - Add probing and userspace reporting support for the standard RISC-V
     ISA extensions Zilsd and Zclsd, which implement load/store dual
     instructions on RV32

   - Abstract the register saving code in setup_sigcontext() so it can
     be used for stateful RISC-V ISA extensions beyond the vector
     extension

   - Add the SBI extension ID and some initial data structure
     definitions for the RISC-V standard SBI debug trigger extension

   - Clean up some code slightly: change some page table functions to
     avoid atomic operations oinn !SMP and to avoid unnecessary casts to
     atomic_long_t; and use the existing RISCV_FULL_BARRIER macro in
