Linus Torvalds 4942fed84b RISC-V Fixes for 6.5-rc8

* The vector ucontext extension has been extended with vlenb.
 * The vector registers ELF core dump note type has been changed to avoid
   aliasing with the CSR type used in embedded systems.
 * Support for accessing vector registers via ptrace() has been reverted.
 * Another build fix for the ISA spec changes around Zifencei/Zicsr that
   manifests on some systems built with binutils-2.37 and gcc-11.2.

Pull RISC-V fixes from Palmer Dabbelt:
 "This is obviously not ideal, particularly for something this late in
  the cycle.

  Unfortunately we found some uABI issues in the vector support while
  reviewing the GDB port, which has triggered a revert -- probably a
  good sign we should have reviewed GDB before merging this, I guess I
  just dropped the ball because I was so worried about the context
  extension and libc suff I forgot. Hence the late revert.

  There's some risk here as we're still exposing the vector context for
  signal handlers, but changing that would have meant reverting all of
  the vector support. The issues we've found so far have been fixed
  already and they weren't absolute showstoppers, so we're essentially
  just playing it safe by holding ptrace support for another release (or
  until we get through a proper userspace code review).

  Summary:

   - The vector ucontext extension has been extended with vlenb

   - The vector registers ELF core dump note type has been changed to
     avoid aliasing with the CSR type used in embedded systems

   - Support for accessing vector registers via ptrace() has been
     reverted

   - Another build fix for the ISA spec changes around Zifencei/Zicsr
     that manifests on some systems built with binutils-2.37 and
     gcc-11.2"
