      [PATCH] powerpc/iseries: Fix double phys_to_abs bug in htab_bolt_mapping · 56ec6462
      Michael Ellerman 提交于
      Before the merge I updated create_pte_mapping() to work for iSeries, by
      calling iSeries_hpte_bolt_or_insert. (4c55130b)
      
      Later we changed iSeries_hpte_insert to cope with the bolting case, and called
      that instead from create_pte_mapping() (which was renamed to htab_bolt_mapping)
      (3c726f8d).
      
      Unfortunately that change introduced a subtle bug, where we pass an absolute
      address to iSeries_hpte_insert() where it expects a physical address. This
      leads to us calling phys_to_abs() twice on the physical address, which is
      seriously bogus.
      
      This only causes a problem if the absolute address from the first translation
      can be looked up again in the chunk_map, which depends on the size and layout
      of memory. I've seen it fail on one box, but not others.
      
      The minimal fix is to pass the physical address to iSeries_hpte_insert(). For
      2.6.17 we should make phys_to_abs() BUG if we try to double-translate an
      address.

      A bug in the assembly code of the vdso can cause gettimeofday() to hang
      or to return incorrect results. The wrong register was used to test for
      pending updates of the calibration variables and to create a dependency
      for subsequent loads. This fixes it.

      [PATCH] powerpc: fix dynamic PCI probe regression · 827c1a6c
      John Rose 提交于
      Some hotplug driver functions were migrated to the kernel for use by EEH
      in commit 2bf6a8fa.
      
      Previously, the PCI Hotplug module had been changed to use the new
      OFDT-based PCI probe when appropriate:
      5fa80fcd
      
      When rpaphp_pci_config_slot() was moved from the rpaphp driver to the
      new kernel function pcibios_add_pci_devices(), the OFDT-based probe
      stuff was dropped.  This patch restores it.

      [MIPS] SMP: Fix initialization order bug. · 9b6695a8
      Ralf Baechle 提交于
          
      A recent change requires cpu_possible_map to be initialized before
      smp_sched_init() but most MIPS platforms were initializing their
      processors in the prom_prepare_cpus callback of smp_prepare_cpus.  The
      simple fix of calling prom_prepare_cpus from one of the earlier SMP
      initialization hooks doesn't work well either since IPIs may require
      init_IRQ() to have completed, so bit the bullet and split
      prom_prepare_cpus into two initialization functions, plat_smp_setup
      which is called early from setup_arch and plat_prepare_cpus called where
      prom_prepare_cpus used to be called.
