      soc: ixp4xx: npe: Fix an IS_ERR() vs NULL check in probe · cd3967be

      The devm_ioremap_resource() function doesn't return NULL, it returns
      error pointers.

      ARM: ixp4xx: include irqs.h where needed · 140d9009

      ARM: ixp4xx: mark ixp4xx_irq_setup as __init · 4ea10150
      Arnd Bergmann authored
      Kbuild complains about ixp4xx_irq_setup not being __init
      itself in some configurations:
      
      WARNING: vmlinux.o(.text+0x85bae4): Section mismatch in reference from the function ixp4xx_irq_setup() to the function .init.text:set_handle_irq()
      The function ixp4xx_irq_setup() references
      the function __init set_handle_irq().
      This is often because ixp4xx_irq_setup lacks a __init
      annotation or the annotation of set_handle_irq is wrong.
      
      I suspect it normally gets inlined, so we get no such warning,
      but clang makes this obvious when the function is left out
      of line.

      arm64: defconfig: Enable FSL_EDMA driver · a019ab40
      Li Yang authored
      Enables the FSL EDMA driver by default.  This also works around an issue
      that imx-i2c driver keeps deferring the probe because of the DMA is not
      ready.  And currently the DMA engine framework can not correctly tell
      if the DMA channels will truly become available later (it will never be
      available if the DMA driver is not enabled).

      Three fixes mostly for dra7 SoC variants that have some devices disabled
      compared to the base SoC. These got broken by the change of making devices
      probe with ti-sysc interconnect target module and went unnnoticed for a

      Fixes for omap variants for dra7 mmc voltage and boot issues
      
      This series contains dra7 mmc voltage fixes, and fixes to the recent
      changes to probe devices with device tree data insteas of legacy
      platform data:
      
      - Two fixes for dra7 mmc that needs 1.8V mode disabled as in case of a
        reset, the bootrom will try to access the mmc card at 3.3V potentially
        damaging the card
      
      - Two regression fixes for am335x d_can. We must allow devices with no
        control registers for ti-sysc interconnect target module driver for
        at least d_can, and we remove the incorrect control registers for
        d_can. And we must configure the osc clock for d_can as otherwise
        register access may fail depending on the bootloader version
      
      - Four regression fixes for dra7 variant dts files to tag rtc and usb4
        as disabled for dra71x and dra76x. These SoC variants do not have
        these devices, and got accidentally enabled when the L4 interconnect
        got defined in the dra7-l4.dtsi for the dra7 SoC family

         - Fix vmalloc TLB flush and map range calculations which lead to

         - Use fault_in_pages_writable() for prefaulting the user stack in the
           FPU code as it's less fragile than the current solution
      
         - Use the PF_KTHREAD flag when checking for a kernel thread instead
           of current->mm as the latter can give the wrong answer due to
           use_mm()
      
         - Compute the vmemmap size correctly for KASLR and 5-Level paging.
           Otherwise this can end up with a way too small vmemmap area.
      
         - Make KASAN and 5-level paging work again by making sure that all
           invalid bits are masked out when computing the P4D offset. This
           worked before but got broken recently when the LDT remap area was
           moved.
      
         - Prevent a NULL pointer dereference in the resource control code
           which can be triggered with certain mount options when the
           requested resource is not available.
      
         - Enforce ordering of microcode loading vs. perf initialization on
           secondary CPUs. Otherwise perf tries to access a non-existing MSR
           as the boot CPU marked it as available.
      
         - Don't stop the resource control group walk early otherwise the
           control bitmaps are not updated correctly and become inconsistent.
      
         - Unbreak kgdb by returning 0 on success from
           kgdb_arch_set_breakpoint() instead of an error code.
      
         - Add more Icelake CPU model defines so depending changes can be

      x86/microcode, cpuhotplug: Add a microcode loader CPU hotplug callback · 78f4e932

      Adric Blake reported the following warning during suspend-resume:

        CPU1 is up
      
      The MSR in question is MSR_TFA_RTM_FORCE_ABORT and that MSR is emulated
      by microcode. The log above shows that the microcode loader callback
      happens after the PMU restoration, leading to the conjecture that
      because the microcode hasn't been updated yet, that MSR is not present
      yet, leading to the #GP.
      
      Add a microcode loader-specific hotplug vector which comes before
      the PERF vectors and thus executes earlier and makes sure the MSR is
      present.

       "This has an unusually high density of tricky fixes:

           This could mislead readers to think that a cgroup is empty when
           it's not. Fixed by making PROCS iterator include dead tasks. I made
           a couple mistakes making this change and this pull request contains
           a couple follow-up patches.
