Connect iSeries up to the standard early debugging infrastructure. To actually use this you need to enable the iSeries early debugging in setup_64.c. Then after the messages are logged hit Ctrl-x Ctrl-x on your console to dump the Hypervisor console buffer. Signed-off-by:

Changes to the serial driver to remove flip buffers have broken the serial jsm driver. It doesn't even compile anymore. The jsm driver was enabled in only one defconfig - ppc64. In order to keep defconfigs building, disable CONFIG_SERIAL_JSM for the time being. Signed-off-by:

The following patch (against 2.6.15-rc5-mm3) fixes a kprobes build break due to changes introduced in the kprobe locking in 2.6.15-rc5-mm3. In addition, the patch reverts back the open-coding of kprobe_mutex. Signed-off-by:

Currently arch_remove_kprobes() is only implemented/required for x86_64 and powerpc. All other architecture like IA64, i386 and sparc64 implementes a dummy function which is being called from arch independent kprobes.c file. This patch removes the dummy functions and replaces it with #define arch_remove_kprobe(p, s) do { } while(0) Signed-off-by: -

Since Kprobes runtime exception handlers is now lock free as this code path is now using RCU to walk through the list, there is no need for the register/unregister{_kprobe} to use spin_{lock/unlock}_isr{save/restore}. The serialization during registration/unregistration is now possible using just a mutex. In the above process, this patch also fixes a minor memory leak for x86_64 and powerpc. Signed-off-by: -

Now that all these entries in the arch ioctl32.c files are gone [1], we can build fs/compat_ioctl.c as a normal object and kill tons of cruft. We need a special do_ioctl32_pointer handler for s390 so the compat_ptr call is done. This is not needed but harmless on all other architectures. Also remove some superflous includes in fs/compat_ioctl.c Tested on ppc64. [1] parisc still had it's PPP handler left, which is not fully correct for ppp and besides that ppp uses the generic SIOCPRIV ioctl so it'd kick in for all netdevice users. We can introduce a proper handler in one of the next patch series by adding a compat_ioctl method to struct net_device but for now let's just kill it - parisc doesn't compile in mainline anyway and I don't want this to block this patchset.

The comment in compat.c is wrong, every architecture provides a get_compat_sigevent() for the IPC compat code already. This basically moves the x86_64 version to common code and removes all the others. Signed-off-by:

The previous change by Kumar Gala in this area led to legacy_serial.c and udbg_16550.c being built as modules when CONFIG_SERIAL_8250=m. Fix this by introducing a new symbol, CONFIG_PPC_UDBG_16550, to control whether these files get built, and arrange for it to be selected for those platforms that need it. Signed-off-by: -

242-eeh-no-percpu-counters.patch Remove per-cpu counters from the EEH code. These statistics counters are incremented at a very low frequency, and the performance gains of per-cpu variables are negligable. By contrast, the counters weren't safe against cpu off/online operations, and its not worth the effort to make them so (other than to turn them into plain globals). Signed-off-by:

239-eeh-multifunction-consolidate.patch New-style firmware will often place multiple different functions under a non-EEH-aware parent.

The CONFIG_PPC_OF symbol is used to mean that the firmware device tree access functions are available. Since we always have a device tree with ARCH=powerpc, make CONFIG_PPC_OF always Y for ARCH=powerpc. This fixes some compile errors reported by Kumar Gala, but in a different way to his patch. This also makes prom_parse.o be compiled only if CONFIG_PPC_OF so that non-OF ARCH=ppc platforms will compile. Signed-off-by: -

This patch adds cpufreq support for all desktop "tower" G5 models. The only G5 models still lacking cpufreq support at this point are the Xserve and possibly the new iMac iSight (not tested). I'll have those added soon. That patch uses the new platform functions interpreter to implement frequency and voltage switching on most models. Note that in order to find the low frequency value, I had to hack something that might now work properly on all models, so if the frequency value reported when running low speed looks bogus to you, please report it to me. (Appart from a bogus reported value, things should work fine). Signed-off-by:
