Linus Torvalds 35b51afd23 RISC-V Patches for the 5.19 Merge Window, Part 1
* Support for the Svpbmt extension, which allows memory attributes to be
   encoded in pages.
 * Support for the Allwinner D1's implementation of page-based memory
   attributes.
 * Support for running rv32 binaries on rv64 systems, via the compat
   subsystem.
 * Support for kexec_file().
 * Support for the new generic ticket-based spinlocks, which allows us to
   also move to qrwlock.  These should have already gone in through the
   asm-geneic tree as well.
 * A handful of cleanups and fixes, include some larger ones around
   atomics and XIP.
