* [PATCH] i386: remove redundant generic_identify() calls when identifying cpusMagnus Damm2006-09-26
| | | | | | | | | | | | | cpu_dev->c_identify is only called from arch/i386/common.c:identify_cpu(), and this after generic_identify() already has been called. There is no need to call this function twice and hook it in c_identify - but I may be wrong, please double check before applying. This patch also removes generic_identify() from cpu.h to avoid unnecessary future nesting. Signed-off-by: Magnus Damm <magnus@valinux.co.jp> Signed-off-by: Andi Kleen <ak@suse.de>

* [PATCH] i386: mark two more functions as __initMagnus Damm2006-09-26
| | | | | | | | | | | cyrix_identify() should be __init because transmeta_identify() is. tsc_init() is only called from setup_arch() which is marked as __init.

* [PATCH] i386: Descriptor and trap table cleanups.Rusty Russell2006-09-26
| | | | | | | | | | | | | | | | | The implementation comes from Zach's [RFC, PATCH 10/24] i386 Vmi descriptor changes: Descriptor and trap table cleanups. Add cleanly written accessors for IDT and GDT gates so the subarch may override them. Note that this allows the hypervisor to transparently tweak the DPL of the descriptors as well as the RPL of segments in those descriptors, with no unnecessary kernel code modification. It also allows the hypervisor implementation of the VMI to tweak the gates, allowing for custom exception frames or extra layers of indirection above the guest fault / IRQ handlers.

* [PATCH] x86: error_code is not safe for kprobesPrasanna S.P2006-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the entry.S:error_entry to .kprobes.text section, since code marked unsafe for kprobes jumps directly to entry.S::error_entry, that must be marked unsafe as well. This patch also moves all the ".previous.text" asm directives to ".previous" for kprobes section. AK: Following a similar i386 patch from Chuck Ebbert AK: Also merged Jeremy's fix in. +From: Jeremy Fitzhardinge <jeremy@goop.org> KPROBE_ENTRY does a .section .kprobes.text, and expects its users to do a .previous at the end of the function. Unfortunately, if any code within the function switches sections, for example .fixup, then the .previous ends up putting all subsequent code into .fixup. Worse, any subsequent .fixup code gets intermingled with the code its supposed to be fixing (which is also in .fixup). It's surprising this didn't cause more havok. The fix is to use .pushsection/.popsection, so this stuff nests properly. A further cleanup would be to get rid of all .section/.previous pairs, since they're inherently fragile. +From: Chuck Ebbert <76306.1226@compuserve.com> Because code marked unsafe for kprobes jumps directly to entry.S::error_code, that must be marked unsafe as well. The easiest way to do that is to move the page fault entry point to just before error_code and let it inherit the same section. Also moved all the ".previous" asm directives for kprobes sections to column 1 and removed ".text" from them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the open-coded early commandline parsing throughout the i386 boot code with the generic mechanism (already used by ppc, powerpc, ia64 and s390). The code was inconsistent with whether it deletes the option from the cmdline or not, meaning some of these will get passed through the environment into init. This transformation is mainly mechanical, but there are some notable parts: 1) Grammar: s/linux never set's it up/linux never sets it up/ 2) Remove hacked-in earlyprintk= option scanning. When someone actually implements CONFIG_EARLY_PRINTK, then they can use early_param(). [AK: actually it is implemented, but I'm adding the early_param it in the next x86-64 patch] 3) Move declaration of generic_apic_probe() from setup.c into asm/apic.h 4) Various parameters now moved into their appropriate files (thanks Andi). 5) All parse functions which examine arg need to check for NULL, except one where it has subtle humor value.

* [PATCH] x86: Add portable getcpu callAndi Kleen2006-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | For NUMA optimization and some other algorithms it is useful to have a fast to get the current CPU and node numbers in user space. x86-64 added a fast way to do this in a vsyscall. This adds a generic syscall for other architectures to make it a generic portable facility. I expect some of them will also implement it as a faster vsyscall. The cache is an optimization for the x86-64 vsyscall optimization. Since what the syscall returns is an approximation anyways and user space often wants very fast results it can be cached for some time. The norma methods to get this information in user space are relatively slow The vsyscall is in a better position to manage the cache because it has direct access to a fast time stamp (jiffies). For the generic syscall optimization it doesn't help much, but enforce a valid argument to keep programs portable I only added an i386 syscall entry for now. Other architectures can follow as needed.

| | | | | | | | | | | | | | | | I've had good experiences with having this on by default on x86-64. It turns nasty hangs into easier to debug oopses. Enable the local APIC wdog by default for systems newer than 2004. This comes from a strange compromise: according to arjan the reason it was off by default was some old IBM systems that corrupted registered when NMI happened in SMI. Can't remember more specific, but >= 2004 should avoid these. It's probably overly broad because most older systems should be ok (and the really old systems won't be supported by the local apic watchdog anyways) Signed-off-by: Andi Kleen <ak@suse.de>

| | | | | | | | | | | | | | | | | | | | | To quote Alan Cox: The default Linux behaviour on an NMI of either memory or unknown is to continue operation. For many environments such as scientific computing it is preferable that the box is taken out and the error dealt with than an uncorrected parity/ECC error get propogated. A small number of systems do generate NMI's for bizarre random reasons such as power management so the default is unchanged. In other respects the new proc/sys entry works like the existing panic controls already in that directory. This is separate to the edac support - EDAC allows supported chipsets to handle ECC errors well, this change allows unsupported cases to at least panic rather than cause problems further down the line.

Only UP kernels are supported in this patch to make reviewing easier. The SMP portion makes a lot more changes. Think of this as a locking mechanism where each bit represents a different counter. In addition, each subsystem should also reserve an appropriate event selection register that will correspond to the performance counter it will be using (this is mainly neccessary for the Pentium 4 chips as they break the 1:1 relationship to performance counters).
