Hi all,

After merging the arm-soc tree, today's linux-next build (powerpc
allnoconfig) failed like this:

drivers/of/address.c: In function 'of_iomap':
drivers/of/address.c:907:10: error: implicit declaration of function 'ioremap_np'; did you mean 'ioremap_wt'? [-Werror=implicit-function-declaration]
  907 |   return ioremap_np(res.start, resource_size(&res));
      |          ^~~~~~~~~~
      |          ioremap_wt
drivers/of/address.c:907:10: warning: returning 'int' from a function with return type 'void *' makes pointer from integer without a cast [-Wint-conversion]
  907 |   return ioremap_np(res.start, resource_size(&res));
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

      |          ^~~~~~~~~~
      |          ioremap_wt

Caused by commits

  7c566bb5e4d5 ("asm-generic/io.h:  Add a non-posted variant of ioremap()")
  89897f739d7b ("of/address: Add infrastructure to declare MMIO as non-posted")
(and maybe some others)

I have reverted 86332e9e3477..7d2d16ccf15d for today.
