       "Nothing major in here, just two different parts:
      
         - A small series from Breno that enables passing the full SQE down
           for ->uring_cmd().
      
           This is a prerequisite for enabling full network socket operations.
           Queued up a bit late because of some stylistic concerns that got
           resolved, would be nice to have this in 6.4-rc1 so the dependent
           work will be easier to handle for 6.5.

           in the 6.3 kernel release (Tobias)"

      Linus Torvalds authored
      Pull more tracing updates from Steven Rostedt:
      
       - Make buffer_percent read/write.
      
         The buffer_percent file is how users can state how long to block on
         the tracing buffer depending on how much is in the buffer. When it
         hits the "buffer_percent" it will wake the task waiting on the
         buffer. For some reason it was set to read-only.
      
         This was not noticed because testing was done as root without
         SELinux, but with SELinux it will prevent even root to write to it
         without having CAP_DAC_OVERRIDE.
      
       - The "touched_functions" was added this merge window, but one of the
         reasons for adding it was not implemented.
      
         That was to show what functions were not only touched, but had either
         a direct trampoline attached to it, or a kprobe or live kernel
         patching that can "hijack" the function to run a different function.
         The point is to know if there's functions in the kernel that may not
         be behaving as the kernel code shows. This can be used for debugging.
      
         TODO: Add this information to kernel oops too.

      Merge branch 'x86-uaccess-cleanup': x86 uaccess header cleanups · d5ed10bb
      Linus Torvalds authored
      Merge my x86 uaccess updates branch.
      
      The LAM ("Linear Address Masking") updates in this release made me
      unhappy about how "access_ok()" was done, and it actually turned out to
      have a couple of small bugs in it too.  This is my cleanup of the code:
      
       - use the sign bit of the __user pointer rather than masking the
         address and checking it against the TASK_SIZE range.
      
         We already did this part for the get/put_user() side, but
         'access_ok()' did the naïve "mask and range check" thing, which not
         only generates nasty code, but also ended up meaning that __access_ok
         itself didn't do a good job, and so copy_from_user_nmi() didn't get
         the check right.
      
       - move all the code that is 64-bit only into the 64-bit version of the
         header file, so that we don't unnecessarily pollute the shared x86
         code and make it look like LAM might work in 32-bit too.
      
       - fix a bug in the address masking (that doesn't end up mattering: in
         this case the fix was to just remove the buggy code entirely).
      
       - a couple of trivial cleanups and added commentary about the
         access_ok() rules.
      
      * x86-uaccess-cleanup:
        x86-64: mm: clarify the 'positive addresses' user address rules
        x86: mm: remove 'sign' games from LAM untagged_addr*() macros
        x86: uaccess: move 32-bit and 64-bit parts into proper <asm/uaccess_N.h> header
        x86: mm: remove architecture-specific 'access_ok()' define
        x86-64: make access_ok() independent of LAM
