* [SPARC64]: Fix sabre pci controllers with new probing scheme.David S. Miller2007-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SIMBA APB bridge is strange, it is a PCI bridge but it lacks some standard OF properties, in particular it lacks a 'ranges' property. What you have to do is read the IO and MEM range registers in the APB bridge to determine the ranges handled by each bridge. So fill in the bus resources by doing that. Since we now handle this quirk in the generic PCI and OF device probing layers, we can flat out eliminate all of that code from the sabre pci controller driver. In fact we can thus eliminate completely another quirk of the sabre driver. It tried to make the two APB bridges look like PBMs but that makes zero sense now (and it's questionable whether it ever made sense). So now just use pbm_A and probe the whole PCI hierarchy using that as the root. This simplification allows many future cleanups to occur. Also, I've found yet another quirk that needs to be worked around while testing this. You can't use the 'class-code' OF firmware property, especially for IDE controllers. We have to read the value out of PCI config space or else we'll see the value the device was showing before it was programmed into native mode. I'm starting to think it might be wise to just read all of the values out of PCI config space instead of using the OF properties. :-/ Signed-off-by: David S. Miller <davem@davemloft.net>

* [SPARC64]: Add clocksource/clockevents support.David S. Miller2007-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'd like to thank John Stul and others for helping me along the way. A lot of cleanups fell out of this. For example, the get_compare() tick_op was totally unused, so was deleted. And the most often used tick_op members were grouped together for cache-friendlyness. The sparc64 TSC is given to the kernel as a one-shot timer. tick_ops->init_timer() simply turns off the privileged bit in the tick register (when possible), and disables the interrupt by setting bit 63 in the compare register. The ->disable_irq() op also sets this bit. tick_ops->add_compare() is changed to: 1) Add the given delta to "tick" not to "compare" 2) Return a boolean which, if true, means that the tick value read after writing the compare value was found to have incremented past the initial tick value. This mirrors logic used in the HPET driver's ->next_event() method. Each tick_ops implementation also now provides a name string. And we feed this into the clocksource and clockevents layers.

| | | | | | | | | | | | | | | | change_page_attr on x86-64 only flushed the TLB for pages that got reverted. That's not correct: it has to be flushed in all cases. This bug was added in some earlier changes. Just flush all pages for now. This could be done more efficiently, but for this late in the release this seem to be the best fix.

* [PATCH] x86: Remove noreplacement optionAndi Kleen2007-04-24
| | | | | | | | | | | | | | noreplacement is dangerous on modern systems because it will not replace the context switch FNSAVE with SSE aware FXSAVE. But other places in the kernel still assume SSE and do FXSAVE and the CPU will then access FXSAVE information with FNSAVE and cause corruption. Easiest way to avoid this is to remove the option. It was mostly for paranoia reasons anyways and alternative()s have been stable for some time. Thanks to Jeremy F. for reporting and helping debug it. Signed-off-by: Andi Kleen <ak@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The save_fp_context()/restore_fp_context() might sleep on accessing user stack and therefore might lose FPU ownership in middle of them.
