      powerpc/512x: dts: remove misplaced IRQ spec from 'soc' node · c65ec135
      Gerhard Sittig authored
      the 'soc' node in the common .dtsi for MPC5121 has an '#interrupt-cells'
      property although this node is not an interrupt controller
      
      remove this erroneously placed property because starting with v3.13-rc1
      lookup and resolution of 'interrupts' specs for peripherals gets misled,
      emits 'no irq domain found' WARN() messages and breaks the boot process
      
        irq: no irq domain found for /soc@80000000 !

      arch/powerpc/kernel: Use %12.12s instead of %12s to avoid memory overflow · e0513d9e
      Chen Gang authored
      for tmp_part->header.name:
          it is "Terminating null required only for names < 12 chars".
          so need to limit the %.12s for it in printk
      
        additional info:
      
          %12s  limit the width, not for the original string output length
                if name length is more than 12, it still can be fully displayed.
                if name length is less than 12, the ' ' will be filled before name.
      
          %.12s truly limit the original string output length (precision)

      powerpc/signals: Improved mark VSX not saved with small contexts fix · ec67ad82
      Michael Neuling authored
      In a recent patch:
        commit c13f20ac
        Author: Michael Neuling <mikey@neuling.org>
        powerpc/signals: Mark VSX not saved with small contexts
      
      We fixed an issue but an improved solution was later discussed after the patch
      was merged.
      
      Firstly, this patch doesn't handle the 64bit signals case, which could also hit
      this issue (but has never been reported).
      
      Secondly, the original patch isn't clear what MSR VSX should be set to.  The
      new approach below always clears the MSR VSX bit (to indicate no VSX is in the
      context) and sets it only in the specific case where VSX is available (ie. when
      VSX has been used and the signal context passed has space to provide the
      state).
      
      This reverts the original patch and replaces it with the improved solution.  It
      also adds a 64 bit version.

      powerpc/kdump: Adding symbols in vmcoreinfo to facilitate dump filtering · 8ff81271
      Hari Bathini authored
      When CONFIG_SPARSEMEM_VMEMMAP option is used in kernel, makedumpfile fails
      to filter vmcore dump as it fails to do vmemmap translations. So far
      dump filtering on ppc64 never had to deal with vmemmap addresses seperately
      as vmemmap regions where mapped in zone normal. But with the inclusion of
      CONFIG_SPARSEMEM_VMEMMAP config option in kernel, this vmemmap address
      translation support becomes necessary for dump filtering. For vmemmap adress
      translation, few kernel symbols are needed by dump filtering tool. This patch
      adds those symbols to vmcoreinfo, which a dump filtering tool can use for
      filtering the kernel dump. Tested this changes successfully with makedumpfile
      tool that supports vmemmap to physical address translation outside zone normal.

      powerpc: allyesconfig should not select CONFIG_CPU_LITTLE_ENDIAN · 962bc221
      Anton Blanchard authored
      Stephen reported a failure in an allyesconfig build.
      CONFIG_CPU_LITTLE_ENDIAN=y gets set but his toolchain is not
      new enough to support little endian. We really want to
      default to a big endian build; Ben suggested using a choice
      which defaults to CPU_BIG_ENDIAN.

      powerpc: Fix error when cross building TAGS & cscope · 924dd50b
      Michael Neuling authored
      Currently if I cross build TAGS or cscope from x86 I get this:
        % make ARCH=powerpc TAGS
        gcc-4.8.real: error: unrecognized command line option ‘-mbig-endian’
        GEN     TAGS
        %
      
      I'm not setting CROSS_COMPILE= as logically I shouldn't need to and I
      haven't needed to in the past when building TAGS or cscope.  Also, the
      above completess correct as the error is not fatal to the build.
      
      This was caused by:
          commit d72b0801
          Author: Ian Munsie <imunsie@au1.ibm.com>
          powerpc: Add ability to build little endian kernels
      
      The below fixes this by testing for the -mbig-endian option before
      adding it.
      
      I've not done the same thing in the little endian case as if
      -mlittle-endian doesn't exist, we probably want to fail quickly as you
      probably have an old big endian compiler.
