 powerpc fixes for 5.15 #3
 
 Fix a regression hit by the IPR SCSI driver, introduced by the recent addition of MSI
 domains on pseries.
 
 A big series including 8 BPF fixes, some with potential security impact and the rest
 various code generation issues.
 
 Fix our program check assembler entry path, which was accidentally jumping into a gas
 macro and generating strange stack frames, which could confuse find_bug().
 
 A couple of fixes, and related changes, to fix corner cases in our machine check handling.
 
 Fix our DMA IOMMU ops, which were not always returning the optimal DMA mask, leading to
 at least one device falling back to 32-bit DMA when it shouldn't.
 
 A fix for KUAP handling on 32-bit Book3S.
 
 Fix crashes seen when kdumping on some pseries systems.

Pull powerpc fixes from Michael Ellerman:
 "A bit of a big batch, partly because I didn't send any last week, and
  also just because the BPF fixes happened to land this week.

  Summary:

   - Fix a regression hit by the IPR SCSI driver, introduced by the
     recent addition of MSI domains on pseries.

   - A big series including 8 BPF fixes, some with potential security
     impact and the rest various code generation issues.

   - Fix our program check assembler entry path, which was accidentally
     jumping into a gas macro and generating strange stack frames, which
     could confuse find_bug().

   - A couple of fixes, and related changes, to fix corner cases in our
     machine check handling.

   - Fix our DMA IOMMU ops, which were not always returning the optimal
     DMA mask, leading to at least one device falling back to 32-bit DMA
     when it shouldn't.

   - A fix for KUAP handling on 32-bit Book3S.

   - Fix crashes seen when kdumping on some pseries systems.
