      soc: fsl: dpio: avoid stack usage warning · 5c4a5999
      Arnd Bergmann authored
      A 1024 byte variable on the stack will warn on any 32-bit architecture
      during compile-testing, and is generally a bad idea anyway:
      fsl/dpio/dpio-service.c: In function 'dpaa2_io_service_enqueue_multiple_desc_fq':
      fsl/dpio/dpio-service.c:495:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
      There are currently no callers of this function, so I cannot tell whether
      dynamic memory allocation is allowed once callers are added. Change
      it to kcalloc for now, if anyone gets a warning about calling this in
      atomic context after they start using it, they can fix it later.

      soc: fsl: dpio: fix incorrect pointer conversions · 0666e3c4
      Arnd Bergmann authored
      Building dpio for 32 bit shows a new compiler warning from converting
      a pointer to a u64:
      drivers/soc/fsl/dpio/qbman-portal.c: In function 'qbman_swp_enqueue_multiple_desc_direct':
      drivers/soc/fsl/dpio/qbman-portal.c:870:14: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
        870 |  addr_cena = (uint64_t)s->addr_cena;
      The variable is not used anywhere, so removing the assignment seems
      to be the correct workaround. After spotting what seemed to be
      some confusion about address spaces, I ran the file through sparse,
      which showed more warnings:
      drivers/soc/fsl/dpio/qbman-portal.c:756:42: warning: incorrect type in argument 1 (different address spaces)
      drivers/soc/fsl/dpio/qbman-portal.c:756:42:    expected void const volatile [noderef] <asn:2> *addr
      drivers/soc/fsl/dpio/qbman-portal.c:756:42:    got unsigned int [usertype] *[assigned] p
      drivers/soc/fsl/dpio/qbman-portal.c:902:42: warning: incorrect type in argument 1 (different address spaces)
      drivers/soc/fsl/dpio/qbman-portal.c:902:42:    expected void const volatile [noderef] <asn:2> *addr
      drivers/soc/fsl/dpio/qbman-portal.c:902:42:    got unsigned int [usertype] *[assigned] p
      Here, the problem is passing a token from memremap() into __raw_readl(),
      which is only defined to work on MMIO addresses but not RAM. Turning
      this into a simple pointer dereference avoids this warning as well.

      ARM: imx: provide v7_cpu_resume() only on ARM_CPU_SUSPEND=y · f1baca88
      Ahmad Fatoum authored
      512a928a ("ARM: imx: build v7_cpu_resume() unconditionally")
      introduced an unintended linker error for i.MX6 configurations that have
      ARM_CPU_SUSPEND=n which can happen if neither CONFIG_PM, CONFIG_CPU_IDLE,
      nor ARM_PSCI_FW are selected.
      Fix this by having v7_cpu_resume() compiled only when cpu_resume() it
      calls is available as well.
      The C declaration for the function remains unguarded to avoid future code
      inadvertently using a stub and introducing a regression to the bug the
      original commit fixed.

      MAINTAINERS: sort field names for all entries · 3b50142d
      Linus Torvalds authored
      This sorts the actual field names too, potentially causing even more
      chaos and confusion at merge time if you have edited the MAINTAINERS
      file.  But the end result is a more consistent layout, and hopefully
      it's a one-time pain minimized by doing this just before the -rc1
      This was entirely scripted:
        ./scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS --order

      MAINTAINERS: sort entries by entry name · 4400b7d6
      Linus Torvalds authored
      They are all supposed to be sorted, but people who add new entries don't
      always know the alphabet.  Plus sometimes the entry names get edited,
      and people don't then re-order the entry.
      Let's see how painful this will be for merging purposes (the MAINTAINERS
      file is often edited in various different trees), but Joe claims there's
      relatively few patches in -next that touch this, and doing it just
      before -rc1 is likely the best time.  Fingers crossed.
      This was scripted with
        /scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS
      but then I also ended up manually upper-casing a few entry names that
      stood out when looking at the end result.

        It addressed the case where a KVM guest triggers a split lock #AC and

        Add proper sanity checks which prevent the unconditional injection
        into the guest and handles the #AC on the host side in the same way as
        user space detections are handled. Depending on the detection mode it

       - Fix the time_for_children symlink in /proc/$PID/ so it properly
         reflects that it part of the 'time' namespace
       - Add the missing userns limit for the allowed number of time
         namespaces, which was half defined but the actual array member was
         not added. This went unnoticed as the array has an exessive empty
         member at the end but introduced a user visible regression as the
         output was corrupted.
       - Prevent further silent ucount corruption by adding a BUILD_BUG_ON()
         to catch half updated data.
