2008-01-30x86, 32-bit: trim memory not covered by wb mtrrsJesse Barnes8-39/+140
On some machines, buggy BIOSes don't properly setup WB MTRRs to cover all available RAM, meaning the last few megs (or even gigs) of memory will be marked uncached. Since Linux tends to allocate from high memory addresses first, this causes the machine to be unusably slow as soon as the kernel starts really using memory (i.e. right around init time). This patch works around the problem by scanning the MTRRs at boot and figuring out whether the current end_pfn value (setup by early e820 code) goes beyond the highest WB MTRR range, and if so, trimming it to match. A fairly obnoxious KERN_WARNING is printed too, letting the user know that not all of their memory is available due to a likely BIOS bug. Something similar could be done on i386 if needed, but the boot ordering would be slightly different, since the MTRR code on i386 depends on the boot_cpu_data structure being setup. This patch fixes a bug in the last patch that caused the code to run on non-Intel machines (AMD machines apparently don't need it and it's untested on other non-Intel machines, so best keep it off).

2008-01-30x86: print which shared library/executable faulted in segfault etc. messages v3Andi Kleen8-12/+63
They now look like: hal-resmgr[13791]: segfault at 3c rip 2b9c8caec182 rsp 7fff1e825d30 error 4 in libacl.so.1.1.0[2b9c8caea000+6000] This makes it easier to pinpoint bugs to specific libraries. And printing the offset into a mapping also always allows to find the correct fault point in a library even with randomized mappings. Previously there was no way to actually find the correct code address inside the randomized mapping. Relies on earlier patch to shorten the printk formats. They are often now longer than 80 characters, but I think that's worth it.

2008-01-30x86: optimize lock prefix switching to run less frequentlyAndi Kleen3-10/+24
On VMs implemented using JITs that cache translated code changing the lock prefixes is a quite costly operation that forces the JIT to throw away and retranslate a lot of code. Previously a SMP kernel would rewrite the locks once for each CPU which is quite unnecessary. This patch changes the code to never switch at boot in the normal case (SMP kernel booting with >1 CPU) or only once for SMP kernel on UP. This makes a significant difference in boot up performance on AMD SimNow! Also I expect it to be a little faster on native systems too because a smp switch does a lot of text_poke()s which each synchronize the pipeline. v1->v2: Rename max_cpus v1->v2: Fix off by one in UP check (Thomas Gleixner) Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2008-01-30x86: use the correct cpuid method to detect MWAIT support for C statesAndi Kleen4-9/+19
Previously there was a AMD specific quirk to handle the case of AMD Fam10h MWAIT not supporting any C states. But it turns out that CPUID already has ways to detectly detect that without using special quirks. The new code simply checks if MWAIT supports at least C1 and doesn't use it if it doesn't. No more vendor specific code. Note this is does not simply clear MWAIT because MWAIT can be still useful even without C states. Credit goes to Ben Serebrin for pointing out the (nearly) obvious.

Rather than remove and/or mangle inb_p/outb_p we want to remove the use of them from inappropriate places. For the PIC/PIT this may eventually depend on 32/64bitism or similar so start by adding inb/outb_pit and inb/outb_pic so that we can make them use any scheme we settle on without disturbing the existing, correct (for ISA), port 0x80 usage. (eg we can make inb_pit use udelay without messing up inb_p). Floppy already does this for the fdc.

2008-01-30x86: fix synchronize_rcu(): high latency on idle systemBenjamin LaHaise1-0/+3
an otherwise idle system takes about 3 ticks per network interface in unregister_netdev() due to multiple calls to synchronize_rcu(), which adds up to quite a few seconds for tearing down thousands of interfaces. By flushing pending rcu callbacks in the idle loop, the system makes progress hundreds of times faster. If this is indeed a sane thing to, it probably needs to be done for other architectures than x86. And yes, the network stack shouldn't call synchronize_rcu() quite so much, but fixing that is a little more involved.
