      Pull printk updates from Petr Mladek:

 - Make %pK behave the same as %p for kptr_restrict == 0 also with
   no_hash_pointers parameter

 - Ignore the default console in the device tree also when console=null
   or console="" is used on the command line

 - Document console=null and console="" behavior

 - Prevent a deadlock and a livelock caused by console_lock in panic()

 - Make console_lock available for panicking CPU

 - Fast query for the next to-be-used sequence number

 - Use the expected return values in printk.devkmsg __setup handler

 - Use the correct atomic operations in wake_up_klogd() irq_work handler

 - Avoid possible unaligned access when handling %4cc printing format

      cacheflush.h: Add forward declaration for struct folio · 30d024b5
      Herbert Xu authored 
      The struct folio is not declared in cacheflush.h so we need to provide
a forward declaration as otherwise users of this header file may get
warnings.

      Pull filesystem folio updates from Matthew Wilcox:
 "Primarily this series converts some of the address_space operations to
  take a folio instead of a page.

  Notably:

   - a_ops->is_partially_uptodate() takes a folio instead of a page and
     changes the type of the 'from' and 'count' arguments to make it
     obvious they're bytes.

   - a_ops->invalidatepage() becomes ->invalidate_folio() and has a
     similar type change.

   - a_ops->launder_page() becomes ->launder_folio()

   - a_ops->set_page_dirty() becomes ->dirty_folio() and adds the
     address_space as an argument.

  There are a couple of other misc changes up front that weren't worth
  separating into their own pull request"
