When we stop allocating percpu memory for not-possible CPUs we must not touch the percpu data for not-possible CPUs at all. The correct way of doing this is to test cpu_possible() or to use for_each_cpu(). This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very few instances of this bug, if any. But the patch converts lots of open-coded test to use the preferred helper macros.

If a user has booted with 'quiet', some important messages don't get displayed which really should. We've seen at least one case where powernow-k8 stopped working, and the user needed a BIOS update that they didn't know about. Signed-off-by: NDave Jones <davej@redhat.com>

Future versions of the Opteron processor may support frequency transitions of 100 MHz, instead of the=20 current 200 MHz. This patch enables the powernow-k8 driver to transition to an odd FID code, indicating a multiple of 100 MHz frequency.

I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

AMD recently discovered that on some hardware, there is a race condition possible when a C-state change request goes onto the bus at the same time as a P-state change request. Both requests happen, but the southbridge hardware only acknowledges the C-state change. The PowerNow! driver is then stuck in a loop, waiting for the P-state change acknowledgement. The driver eventually times out, but can no longer perform P-state changes. It turns out the solution is to resend the P-state change, which the southbridge will acknowledge normally. Thanks to Johannes Winkelmann for reporting this and testing the fix.

Via reading the code, my understanding is that powernow-k8 uses preempt_disable to ensure that driver->target doesn't migrate across cpus whilst it's accessing per processor registers, however set_cpus_allowed will provide this for us. Additionally, remove schedule() calls from set_cpus_allowed as set_cpus_allowed ensures that you're executing on the target processor on return.

can be encoded in the current driver's 4 bit frequency field. This patch updates the driver to support Rev F including 6 bit FIDs and processor ID updates. This should apply cleanly whether or not the dual-core bugfix I sent out last week is applied. I'd prefer that both get applied, of course.

each core be created in the _cpu_init function call. The cpufreq infrastructure doesn't call _cpu_init for the second core in each processor. Some systems crashed when _get was called with an odd-numbered core because it tried to dereference a NULL pointer since the data structure had not been created. The attached patch solves the problem by initializing data structures for all shared cores in the _cpu_init function. It should apply to 2.6.12-rc6 and has been tested by AMD and Sun.

With the release of the dual-core AMD Opterons last week, it's high time that cpufreq supported them. The attached patch applies cleanly to 2.6.12-rc3 and updates powernow-k8 to support the latest Athlon 64 and Opteron processors. Update the driver to version 1.40.0 and provide support for dual-core processors. Signed-off-by: NMark Langsdorf <mark.langsdorf@amd.com> Signed-off-by: NDave Jones <davej@redhat.com>

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!
