      [PATCH] powerpc: Merge vdso's and add vdso support to 32 bits kernel · a7f290da
      Benjamin Herrenschmidt authored
      This patch moves the vdso's to arch/powerpc, adds support for the 32
      bits vdso to the 32 bits kernel, rename systemcfg (finally !), and adds
      some new (still untested) routines to both vdso's: clock_gettime() with
      support for CLOCK_REALTIME and CLOCK_MONOTONIC, clock_getres() (same
      clocks) and get_tbfreq() for glibc to retreive the timebase frequency.
      
      Tom,Steve: The implementation of get_tbfreq() I've done for 32 bits
      returns a long long (r3, r4) not a long. This is such that if we ever
      add support for >4Ghz timebases on ppc32, the userland interface won't
      have to change.
      
      I have tested gettimeofday() using some glibc patches in both ppc32 and
      ppc64 kernels using 32 bits userland (I haven't had a chance to test a
      64 bits userland yet, but the implementation didn't change and was
      tested earlier). I haven't tested yet the new functions.

      [PATCH] ppc64: dynamically allocate segment tables · 533f0817
      David Gibson authored
      PPC64 machines before Power4 need a segment table page allocated for each
      CPU.  Currently these are allocated statically in a big array in head.S for
      all CPUs.  The segment tables need to be in the first segment (so
      do_stab_bolted doesn't take a recursive fault on the stab itself), but
      other than that there are no constraints which require the stabs for the
      secondary CPUs to be statically allocated.
      
      This patch allocates segment tables dynamically during boot, using
      lmb_alloc() to ensure they are within the first 256M segment.  This reduces
      the kernel image size by 192k...
      
      Tested on RS64 iSeries, POWER3 pSeries, and POWER5.

      [PATCH] ppc64: Add driver for BPA interrupt controllers · cebf589c
      Arnd Bergmann authored
      Add support for the integrated interrupt controller on BPA
      CPUs. There is one of those for each SMT thread.
      
      The mapping of interrupt numbers to HW interrupt sources
      is described in arch/ppc64/kernel/bpa_iic.h.
      
      This version hardcodes the 'Spider' chip as the secondary
      interrupt controller. That is not really generic for the
      architecture, but at the moment it is the only secondary
      PIC that exists.
      
      A little more work will be needed on this as soon as
      we have boards with multiple external interrupt controllers.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
