      [PATCH] powerpc: Merge bitops.h · a0e60b20
      David Gibson authored 
      

Here's a revised version.  This re-introduces the set_bits() function
from ppc64, which I removed because I thought it was unused (it exists
on no other arch).  In fact it is used in the powermac interrupt code
(but not on pSeries).

- We use LARXL/STCXL macros to generate the right (32 or 64 bit)
  instructions, similar to LDL/STL from ppc_asm.h, used in fpu.S

- ppc32 previously used a full "sync" barrier at the end of
  test_and_*_bit(), whereas ppc64 used an "isync".  The merged version
  uses "isync", since I believe that's sufficient.

- The ppc64 versions of then minix_*() bitmap functions have changed
  semantics.  Previously on ppc64, these functions were big-endian
  (that is bit 0 was the LSB in the first 64-bit, big-endian word).
  On ppc32 (and x86, for that matter, they were little-endian.  As far
  as I can tell, the big-endian usage was simply wrong - I guess
  no-one ever tried to use minixfs on ppc64.

- On ppc32 find_next_bit() and find_next_zero_bit() are no longer
  inline (they were already out-of-line on ppc64).

- For ppc64, sched_find_first_bit() has moved from mmu_context.h to
  the merged bitops.  What it was doing in mmu_context.h in the first
  place, I have no idea.

- The fls() function is now implemented using the cntlzw instruction
  on ppc64, instead of generic_fls(), as it already was on ppc32.

- For ARCH=ppc, this patch requires adding arch/powerpc/lib to the
  arch/ppc/Makefile.  This in turn requires some changes to
  arch/powerpc/lib/Makefile which didn't correctly handle ARCH=ppc.

Built and running on G5.

      [PATCH] powerpc: move rtas_fw.c out of platforms/pseries · e9add2ee
      Arnd Bergmann authored 
      

Cell uses the same code as pSeries for flashing the firmware
through rtas, so the implementation should not be part of
platforms/pseries.

Put it into arch/powerpc/kernel instead.

      [PATCH] powerpc: Rename BPA to Cell · f3f66f59
      Arnd Bergmann authored 
      

The official name for BPA is now CBEA (Cell Broadband
Engine Architecture). This patch renames all occurences
of the term BPA to 'Cell' for easier recognition.

      powerpc: make mem= work on iSeries again · bec7c458
      Stephen Rothwell authored 
      

By parsing the command line earlier, we can add the mem= value to the
flattened device tree and let the generic code sort out the memory limit
for us.

      powerpc: Fix time setting bug on 32-bit · 5f6b5b97
      Paul Mackerras authored 
      

This fixes a bug where settimeofday would set the wrong parameters
in do_gtod, resulting in gettimeofday returning a value about 4
hours after the correct time.  The bug was that we divided a
negative 64-bit value with do_div, which treated it as unsigned
and gave us a result that was approximately 1.8e10 too large
(since the divisor was 1e9).
