Now we have high res timers there is less of a reason for a high HZ value. Furthermore I think there a few reasons we should reduce HZ to 100: - Timer interrupt overhead. While this overhead is small, there are applications that are very sensitive to jitter (eg some HPC apps). - Issues with the timer wheel code. When coming out of NO_HZ idle we work our way through the timer code one tick at a time. If we have been idle a long time, this adds up - I sometimes see milliseconds of time spent in that loop. Long term we should fix the timer wheel algorithm, but for now if we reduce HZ then we reduce the amount of work the timer code has to do when coming out of idle.

Machines with acenic adapters are rare these days, so we may as well make it a module. Cramfs is also very rarely used so we can make it a module.

The overhead of HCALL_STATS is quite high and the functionality is very rarely used. Key statistics are also missing (eg min/max). With the new hcall tracepoints much more powerful tracing can be done in a kernel module. Lets disable this by default.

Adds a character driver for BSR support on IBM POWER systems including Power5 and Power6. The BSR is an optional processor facility not currently implemented by any other processors. It's primary purpose is fast large SMP synchronization. More details on the BSR are in comments to the code which follows. This patch adds BSR driver to pseries_defconfig.

This updates all the defconfigs in arch/powerpc/configs except iseries and ps3, which were updated by the preceding commits. This mostly takes the defaults, except that I turned on tickless idle and high-resolution timers for everything, and turned off instrumentation support and "Fair group CPU scheduler" for the smaller/embedded platforms.

When checking out the new NO_HZ support in powerpc, I noticed we never slept for more than 2 seconds. It turns out SLAB has a 2 second per cpu timer that causes this. After switching to SLUB I see some nice 4 second sleeps which is the limit on this POWER6 box (the decrementer ticks at 512MHz): slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 3.96 sec slept 3.80 sec slept 2.99 sec Since SLUB is now the default and some powerpc defconfigs already enable it, lets enable SLUB across the board for consistency. While doing this I also noticed that the maple defconfig has SLAB debugging enabled which is sure to make your box nice and slow. Fix that too.

The config option SPAN_OTHER_NODES was created so that we could make pSeries numa layouts work within the DISCONTIG memory model. Now that DISCONTIG has been replaced by SPARSEMEM, we can eliminate this option. I'll be sending a separate patch to Andrew to remove the arch independent code as pSeries was the only arch that needed this.

This moves the rtas RTC callbacks to rtas-rtc.c in arch/powerpc/kernel, and kills the rest of arch/ppc64/kernel/rtc.c which was just a duplicate of the genrtc functionality.
