This morning, I looked at linux-next to find out how arch/arm is doing
for the next merge window.

$ git diff -C --cumulative v2.6.39-rc1... arch
  19.7% arch/arm/mach-imx/
  19.2% arch/arm/mach-mx3/
   3.4% arch/arm/mach-mxc91231/
  18.1% arch/arm/mach-ux500/
  74.1% arch/arm/
   3.2% arch/m68k/
   4.0% arch/mips/lantiq/
   6.9% arch/mips/
   3.1% arch/x86/kvm/
   7.6% arch/x86/
 100.0% arch/
$ git diff -C --cumulative v2.6.39-rc1... arch/arm
   4.7% arch/arm/mach-imx/
   5.9% arch/arm/mach-msm/
   6.3% arch/arm/mach-mx3/
   8.8% arch/arm/mach-mxc91231/
   7.6% arch/arm/mach-ux500/include/mach/
  46.1% arch/arm/mach-ux500/
   3.6% arch/arm/mach-zynq/
   5.9% arch/arm/plat-mxc/include/mach/
   7.3% arch/arm/plat-mxc/
 100.0% arch/arm/
$ git diff -C --shortstat v2.6.39-rc1... arch/arm
 450 files changed, 11973 insertions(+), 5736 deletions(-)

Note that with --cumulative, the %age given includes all child directories
(so the 74% for arch/arm includes everything below it).

So, almost 75% of changes in arch are down to arch/arm.  For arch/arm,
there's 6k new lines introduced - so there's a significant amount of new
work there.

Folk may want to consider that we're three weeks from Linus' rant, and
there's little sign of the situation changing.  It looks to me from
these statistics that it's business as usual.

Please take a moment to consider how Linus will react to this at the
next merge window.
