      Commit 78d3bb44 ("kbuild: Fix <linux/version.h> for empty SUBLEVEL
      or PATCHLEVEL") fixed the build error for empty SUBLEVEL or PATCHLEVEL
      by prepending a zero.
      
      Commit 9b82f13e ("kbuild: clamp SUBLEVEL to 255") re-introduced
      this issue.
      
      This time, we cannot take the same approach because we have C code:
      
        #define LINUX_VERSION_PATCHLEVEL $(PATCHLEVEL)
        #define LINUX_VERSION_SUBLEVEL $(SUBLEVEL)
      
      Replace empty SUBLEVEL/PATCHLEVEL with a zero.

      kbuild: make -s option take precedence over V=1 · 22149454
      Masahiro Yamada authored
      'make -s' should be really silent. However, 'make -s V=1' prints noisy
      log messages from some shell scripts.
      
      Of course, such a combination is odd, but the build system needs to do
      the right thing even if a user gives strange input.
      
      If -s is given, KBUILD_VERBOSE should be forced to 0.

      So, the user-supplied whitelist and LTO-specific white list must be
      independent of each other.
      
      I refactored the shell script so CONFIG_MODVERSIONS and CONFIG_CLANG_LTO
      handle whitelists in the same way.

      Linus Torvalds authored
      Pull io_uring thread rewrite from Jens Axboe:
       "This converts the io-wq workers to be forked off the tasks in question
        instead of being kernel threads that assume various bits of the
        original task identity.
      
        This kills > 400 lines of code from io_uring/io-wq, and it's the worst
        part of the code. We've had several bugs in this area, and the worry
        is always that we could be missing some pieces for file types doing
        unusual things (recent /dev/tty example comes to mind, userfaultfd
        reads installing file descriptors is another fun one... - both of
        which need special handling, and I bet it's not the last weird oddity
        we'll find).
      
        With these identical workers, we can have full confidence that we're
        never missing anything. That, in itself, is a huge win. Outside of
        that, it's also more efficient since we're not wasting space and code
        on tracking state, or switching between different states.
      
        I'm sure we're going to find little things to patch up after this
        series, but testing has been pretty thorough, from the usual
        regression suite to production. Any issue that may crop up should be
        manageable.
      
        There's also a nice series of further reductions we can do on top of
        this, but I wanted to get the meat of it out sooner rather than later.
        The general worry here isn't that it's fundamentally broken. Most of
        the little issues we've found over the last week have been related to
        just changes in how thread startup/exit is done, since that's the main
        difference between using kthreads and these kinds of threads. In fact,
        if all goes according to plan, I want to get this into the 5.10 and
        5.11 stable branches as well.
      
        That said, the changes outside of io_uring/io-wq are:
      
         - arch setup, simple one-liner to each arch copy_thread()
           implementation.
      
         - Removal of net and proc restrictions for io_uring, they are no
           longer needed or useful"

      csky: Fixup swapon · af94002b
      Guo Ren authored
      Current csky's swappon is broken by wrong swap PTE entry format.
      Now redesign the new format for abiv1 & abiv2 and make swappon +
      zram work properly on csky machines.
      
      C-SKY PTE has VALID, DIRTY to emulate PRESENT, READ, WRITE, EXEC
      attributes. GLOBAL bit is shared by two pages in the same tlb
      entry. So we need to keep GLOBAL, VALID, PRESENT zero in swp_pte.
      
      To distinguish PAGE_NONE and swp_pte, we need to use an additional
      bit (abiv1 is _PAGE_READ, abiv2 is _PAGE_WRITE).
