| * [PATCH] x86: Refactor thermal throttle processingDmitriy Zavin2006-09-262-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor the event processing (syslog messaging and rate limiting) into separate file therm_throt.c. This allows consistent reporting of CPU thermal throttle events. After ACK'ing the interrupt, if the event is current, the user (p4.c/mce_intel.c) calls therm_throt_process to log (and rate limit) the event. If that function returns 1, the user has the option to log things further (such as to mce_log in x86_64).

| * [PATCH] x86: Allow disabling early pci scans with pci=noearly or disallowing ↵Andi Kleen2006-09-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | conf1 Some buggy systems can machine check when config space accesses happen for some non existent devices. i386/x86-64 do some early device scans that might trigger this. Allow pci=noearly to disable this. Also when type 1 is disabling also don't do any early accesses which are always type1. This moves the pci= configuration parsing to be a early parameter. I don't think this can break anything because it only changes a single global that is only used by PCI.

| * [PATCH] i386/x86-64: Work around gcc bug with noreturn functions in unwinderJan Beulich2006-09-262-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current gcc generates calls not jumps to noreturn functions. When that happens the return address can point to the next function, which confuses the unwinder. This patch works around it by marking asynchronous exception frames in contrast normal call frames in the unwind information. Then teach the unwinder to decode this. For normal call frames the unwinder now subtracts one from the address which avoids this problem. The standard libgcc unwinder uses the same trick. It doesn't include adjustment of the printed address (i.e. for the original example, it'd still be kernel_math_error+0 that gets displayed, but the unwinder wouldn't get confused anymore. This only works with binutils 2.6.17+ and some versions of H.J.Lu's 2.6.16 unfortunately because earlier binutils don't support .cfi_signal_frame [AK: added automatic detection of the new binutils and wrote description] Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Andi Kleen <ak@suse.de>

The function was originally added to get some basic oops information out even if the GS register was corrupted. However that didn't work for some anymore because printk is needed to print the oops and it uses smp_processor_id() already. Also GS register corruptions are not particularly common anymore. This also helps the Xen port which would otherwise need to do this in a special way because it can't access the local APIC.

| * [PATCH] non lazy "sleazy" fpu implementationArjan van de Ven2006-09-261-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now the kernel on x86-64 has a 100% lazy fpu behavior: after *every* context switch a trap is taken for the first FPU use to restore the FPU context lazily. This is of course great for applications that have very sporadic or no FPU use (since then you avoid doing the expensive save/restore all the time). However for very frequent FPU users... you take an extra trap every context switch. The patch below adds a simple heuristic to this code: After 5 consecutive context switches of FPU use, the lazy behavior is disabled and the context gets restored every context switch. If the app indeed uses the FPU, the trap is avoided. (the chance of the 6th time slice using FPU after the previous 5 having done so are quite high obviously). After 256 switches, this is reset and lazy behavior is returned (until there are 5 consecutive ones again). The reason for this is to give apps that do longer bursts of FPU use still the lazy behavior back after some time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now for a completely different but trivial approach. I just boot tested it with 255 CPUS and everything worked. Currently everything (except module data) we place in the per cpu area we know about at compile time. So instead of allocating a fixed size for the per_cpu area allocate the number of bytes we need plus a fixed constant for to be used for modules.
