Pull parisc updates from Helge Deller:
 "Fixes:

   - When we added basic vDSO support in kernel 5.18 we introduced a bug
     which prevented a mmap() of graphic card memory. This is because we
     used the DMB (data memory break trap bit) page flag as special-bit,
     but missed to clear that bit when loading the TLB.

   - Graphics card memory size was not correctly aligned

   - Spelling fixes (from Colin Ian King)

  Enhancements:

   - PDC console (which uses firmware calls) now rewritten as early
     console

   - Reduced size of alternative tables"

<title>parisc: Remove 64bit access on 32bit machines</title>

<id>77bfc8bdb5a1cdbcea21daccdf1686e1bfea3db6</id>
<content type='text'>
The parisc was using some readq/writeq accessors without special
considerations as to what will happen on 32bit CPUs if you do
this. Maybe we have been lucky that it "just worked" on 32bit
due to the compiler behaviour, or the code paths were never
executed.

Fix the two offending code sites like this:

arch/parisc/lib/iomap.c:

- Put ifdefs around the 64bit accessors and make sure
  that ioread64, ioread64be, iowrite64 and iowrite64be
  are not available on 32bit builds.

- Also fold in a bug fix where 64bit access was by
  mistake using 32bit writel() accessors rather
  than 64bit writeq().

drivers/parisc/sba_iommu.c:

- Access any 64bit registers using _lo_hi-semantics by way
  of the readq and writeq operations provided by
  &lt;linux/io-64-nonatomic-lo-hi.h&gt;
