      powerpc: pci-ioda: Use a single function to emit logging messages · 6d31c2fa
      Joe Perches authored
      No need for 3 functions when a single one will do.
      
      Modify the function declaring macros to call the single function.
      
      Reduces object code size a little:
      
      $ size arch/powerpc/platforms/powernv/pci-ioda.o*
         text	   data	    bss	    dec	    hex	filename

      The return value is unnecessary and unused, so make the functions

      powerpc/mm: Unindent htab_dt_scan_page_sizes() · 9e34992a
      Michael Ellerman authored
      We can unindent the bulk of htab_dt_scan_page_sizes() by returning early
      if the property is not found. That is nice in and of itself, but also
      has the advantage of making it clear that we always return success once
      we have found the ibm,segment-page-sizes property.

      powerpc/ppc64: Clean up the boot-time settings display · bdce97e9
      Michael Ellerman authored
      At boot we display a bunch of low level settings which can be useful to
      know, and can help to spot bugs when things are fundamentally
      misconfigured.
      
      At the moment they are very widely spaced, so that we can accommodate
      the line:
      
        ppc64_caches.dcache_line_size = 0xYY
      
      But we only print that line when the cache line size is not 128, ie.
      almost never, so it just makes the display look odd usually.
      
      The ppc64_caches prefix is redundant so remove it, which means we can
      align things a bit closer for the common case. While we're there
      replace the last use of camelCase (physicalMemorySize), and use
      phys_mem_size.

      powerpc: some changes in numa_setup_cpu() · 297cf502
      Li Zhong authored
      this patches changes some error handling logics in numa_setup_cpu(),
      when cpu node is not found, so:
      
      if the cpu is possible, but not present, -1 is kept in numa_cpu_lookup_table,
      so later, if the cpu is added, we could set correct numa information for it.
      
      if the cpu is present, then we set the first online node to
      numa_cpu_lookup_table instead of 0 ( in case 0 might not be an online node? )

      powerpc: Only set numa node information for present cpus at boottime · bc3c4327
      Li Zhong authored
      As Nish suggested, it makes more sense to init the numa node informatiion
      for present cpus at boottime, which could also avoid WARN_ON(1) in
      numa_setup_cpu().
      
      With this change, we also need to change the smp_prepare_cpus() to set up
      numa information only on present cpus.
      
      For those possible, but not present cpus, their numa information
      will be set up after they are started, as the original code did before commit
      2fabf084.

      powerpc: Fix warning reported by verify_cpu_node_mapping() · 70ad2375
      Li Zhong authored
      With commit 2fabf084 ("powerpc: reorder per-cpu NUMA information's
      initialization"), during boottime, cpu_numa_callback() is called
      earlier(before their online) for each cpu, and verify_cpu_node_mapping()
      uses cpu_to_node() to check whether siblings are in the same node.
      
      It skips the checking for siblings that are not online yet. So the only
      check done here is for the bootcpu, which is online at that time. But
      the per-cpu numa_node cpu_to_node() uses hasn't been set up yet (which
      will be set up in smp_prepare_cpus()).
      
      So I saw something like following reported:
      [    0.000000] CPU thread siblings 1/2/3 and 0 don't belong to the same
      node!
      
      As we don't actually do the checking during this early stage, so maybe
      we could directly call numa_setup_cpu() in do_init_bootmem().

      powerpc: Split out instruction analysis part of emulate_step() · be96f633
      Paul Mackerras authored
      This splits out the instruction analysis part of emulate_step() into
      a separate analyse_instr() function, which decodes the instruction,
      but doesn't execute any load or store instructions.  It does execute
      integer instructions and branches which can be executed purely by
      updating register values in the pt_regs struct.  For other instructions,
      it returns the instruction type and other details in a new
      instruction_op struct.  emulate_step() then uses that information
      to execute loads, stores, cache operations, mfmsr, mtmsr[d], and
      (on 64-bit) sc instructions.
      
      The reason for doing this is so that the KVM code can use it instead
      of having its own separate instruction emulation code.  Possibly the
      alignment interrupt handler could also use this.

      powerpc: Check flat device tree version at boot · ad72a279
      Michael Ellerman authored
      In commit e6a6928c "of/fdt: Convert FDT functions to use libfdt",
      the kernel stopped supporting old flat device tree formats. The minimum
      supported version is now 0x10.
      
      There was a checking function added, early_init_dt_verify(), but it's
      not called on powerpc.
      
      The result is, if you boot with an old flat device tree, the kernel will
      fail to parse it correctly, think you have no memory etc. and hilarity
      ensues.
      
      We can't really fix it, but we can at least catch the fact that the
      device tree is in an unsupported format and panic(). We can't call
      BUG(), it's too early.

      powerpc/powernv: Don't call generic code on offline cpus · d6a4f709
      Paul Mackerras authored
      On PowerNV platforms, when a CPU is offline, we put it into nap mode.
      It's possible that the CPU wakes up from nap mode while it is still
      offline due to a stray IPI.  A misdirected device interrupt could also
      potentially cause it to wake up.  In that circumstance, we need to clear
      the interrupt so that the CPU can go back to nap mode.
      
      In the past the clearing of the interrupt was accomplished by briefly
      enabling interrupts and allowing the normal interrupt handling code
      (do_IRQ() etc.) to handle the interrupt.  This has the problem that
      this code calls irq_enter() and irq_exit(), which call functions such
      as account_system_vtime() which use RCU internally.  Use of RCU is not
      permitted on offline CPUs and will trigger errors if RCU checking is
      enabled.
      
      To avoid calling into any generic code which might use RCU, we adopt
      a different method of clearing interrupts on offline CPUs.  Since we
      are on the PowerNV platform, we know that the system interrupt
      controller is a XICS being driven directly (i.e. not via hcalls) by
      the kernel.  Hence this adds a new icp_native_flush_interrupt()
      function to the native-mode XICS driver and arranges to call that
      when an offline CPU is woken from nap.  This new function reads the
      interrupt from the XICS.  If it is an IPI, it clears the IPI; if it
      is a device interrupt, it prints a warning and disables the source.
      Then it does the end-of-interrupt processing for the interrupt.
      
      The other thing that briefly enabling interrupts did was to check and
      clear the irq_happened flag in this CPU's PACA.  Therefore, after
      flushing the interrupt from the XICS, we also clear all bits except
      the PACA_IRQ_HARD_DIS (interrupts are hard disabled) bit from the
      irq_happened flag.  The PACA_IRQ_HARD_DIS flag is set by power7_nap()
      and is left set to indicate that interrupts are hard disabled.  This
      means we then have to ignore that flag in power7_nap(), which is
      reasonable since it doesn't indicate that any interrupt event needs
      servicing.

      powerpc: Use CONFIG_ARCH_HAS_FAST_MULTIPLIER · 423216ed
      Anton Blanchard authored
      I ran some tests to compare hash_64 using shifts and multiplies.
      The results:
      
      POWER6:	~2x slower
      POWER7: ~2x faster
      POWER8: ~2x faster
      
      Now we have a proper config option, select
      CONFIG_ARCH_HAS_FAST_MULTIPLIER on POWER7 and POWER8.

      of_device_ids (i.e. compatible strings and the respective data) are not
      supposed to change at runtime. All functions working with of_device_ids
      provided by <linux/of.h> work with const of_device_ids. This allows to
      mark all struct of_device_id const, too.
      
      While touching these line also put the __init annotation at the right
