      sbitmap: Protect swap_lock from softirqs · 37198768
      Steven Rostedt (VMware) authored
      The swap_lock used by sbitmap has a chain with locks taken from softirq,
      but the swap_lock is not protected from being preempted by softirqs.
      
      A chain exists of:
      
       sbq->ws[i].wait -> dispatch_wait_lock -> swap_lock
      
      Where the sbq->ws[i].wait lock can be taken from softirq context, which
      means all locks below it in the chain must also be protected from
      softirqs.

        The other two are early-rc fixes that are not super serious but pretty

      kernel/sys.c: Clarify that UNAME26 does not generate unique versions anymore · b7285b42
      Jonathan Neuschäfer authored
      UNAME26 is a mechanism to report Linux's version as 2.6.x, for
      compatibility with old/broken software.  Due to the way it is
      implemented, it would have to be updated after 5.0, to keep the
      resulting versions unique.  Linus Torvalds argued:
      
       "Do we actually need this?
      
        I'd rather let it bitrot, and just let it return random versions. It
        will just start again at 2.4.60, won't it?
      
        Anybody who uses UNAME26 for a 5.x kernel might as well think it's
        still 4.x. The user space is so old that it can't possibly care about
        differences between 4.x and 5.x, can it?
      
        The only thing that matters is that it shows "2.4.<largeenough>",
        which it will do regardless"

      Pull ARM SoC fixes from Olof Johansson:
       "A bigger batch than I anticipated this week, for two reasons:
      
         - Some fallout on Davinci from board file -> DTB conversion, that
           also includes a few longer-standing fixes (i.e. not recent
           regressions).
      
         - drivers/reset material that has been in linux-next for a while, but
           didn't get sent to us until now for a variety of reasons
           (maintainer out sick, holidays, etc). There's a functional
           dependency in there such that one platform (Altera's SoCFPGA) won't
           boot without one of the patches; instead of reverting the patch
           that got merged, I looked at this set and decided it was small
           enough that I'll pick it up anyway. If you disagree I can revisit
           with a smaller set.
      
        That being said, there's also a handful of the usual stuff:
      
         - Fix for a crash on Armada 7K/8K when the kernel touches
           PSCI-reserved memory
      
         - Fix for PCIe reset on Macchiatobin (Armada 8K development board,
           what this email is sent from in fact :)
      
         - Enable a few new-merged modules for Amlogic in arm64 defconfig
      
         - Error path fixes on Integrator
      
         - Build fix for Renesas and Qualcomm
      
         - Initialization fix for Renesas RZ/G2E

        sysfs should not be crashing and preventing people from seeing where
        they went wrong. Now it properly recovers and warns the developer.
      
        The documentation update removes the use of BUS_ATTR() as the kernel
        is moving away from this to use the specific BUS_ATTR_RW() and friends
        instead. There are pending patches in all of the different subsystems
        to remove the last users of this macro, but for now, don't advertise
        it should be used anymore to keep new ones from being introduced.
