      nfsd: auth: Fix gid sorting when rootsquash enabled · 19952667
      Ben Hutchings authored
      Commit bdcf0a42 ("kernel: make groups_sort calling a responsibility
      group_info allocators") appears to break nfsd rootsquash in a pretty
      major way.
      
      It adds a call to groups_sort() inside the loop that copies/squashes
      gids, which means the valid gids are sorted along with the following
      garbage.  The net result is that the highest numbered valid gids are
      replaced with any lower-valued garbage gids, possibly including 0.
      
      We should sort only once, after filling in all the gids.
      
      Fixes: bdcf0a42

      net/mlx5e: Fix fixpoint divide exception in mlx5e_am_stats_compare · e58edaa4
      Talat Batheesh authored
      Helmut reported a bug about division by zero while
      running traffic and doing physical cable pull test.
      
      When the cable unplugged the ppms become zero, so when
      dividing the current ppms by the previous ppms in the
      next dim iteration there is division by zero.
      
      This patch prevent this division for both ppms and epms.

      x86: Use __nostackprotect for sme_encrypt_kernel · 91cfc88c
      Laura Abbott authored
      Commit bacf6b49 ("x86/mm: Use a struct to reduce parameters for SME
      PGD mapping") moved some parameters into a structure.
      
      The structure was large enough to trigger the stack protection canary in
      sme_encrypt_kernel which doesn't work this early, causing reboots.
      
      Mark sme_encrypt_kernel appropriately to not use the canary.

      alpha/PCI: Fix noname IRQ level detection · 86be8993
      Lorenzo Pieralisi authored
      The conversion of the alpha architecture PCI host bridge legacy IRQ
      mapping/swizzling to the new PCI host bridge map/swizzle hooks carried
      out through:
      
      commit 0e4c2eeb ("alpha/PCI: Replace pci_fixup_irqs() call with
      host bridge IRQ mapping hooks")
      
      implies that IRQ for devices are now allocated through pci_assign_irq()
      function in pci_device_probe() that is called when a driver matching a
      device is found in order to probe the device through the device driver.
      
      Alpha noname platforms required IRQ level programming to be executed
      in sio_fixup_irq_levels(), that is called in noname_init_pci(), a
      platform hook called within a subsys_initcall.
      
      In noname_init_pci(), present IRQs are detected through
      sio_collect_irq_levels() that check the struct pci_dev->irq number
      to detect if an IRQ has been allocated for the device.
      
      By the time sio_collect_irq_levels() is called, some devices may still
      have not a matching driver loaded to match them (eg loadable module)
      therefore their IRQ allocation is still pending - which means that
      sio_collect_irq_levels() does not programme the correct IRQ level for
      those devices, causing their IRQ handling to be broken when the device
      driver is actually loaded and the device is probed.
      
      Fix the issue by adding code in the noname map_irq() function
      (noname_map_irq()) that, whilst mapping/swizzling the IRQ line, it also
      ensures that the correct IRQ level programming is executed at platform
      level, fixing the issue.
      
      Fixes: 0e4c2eeb
