* [PARISC] import necessary bits of libgcc.aKyle McMartin2007-10-1831-24/+4628
| | | | | | | | | Currently we're hacking libs-y to include libgcc.a, but this has unforeseen consequences since the userspace libgcc is linked with fpregs enabled. We need the kernel to stop using fpregs in an uncontrolled manner to implement lazy fpu state saves. Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
* [PARISC] Use page allocator instead of slab allocator in pci-dma.cChristoph Lameter2007-10-181-5/+4
| | | | | | | | | | | | | | | | Slab pages obtained via kmalloc are not cacheline aligned. Nor is it advisable to perform VM operations designed for page allocator pages on memory obtained via kmalloc. So replace the page sized allocations in kernel/pci-dma.c with page allocator pages.

| * x86: vdso linker script cleanupRoland McGrath2007-10-171-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I can't see the reason ". = VDSO_PRELINK + 0x900;" was ever there in the linker script for the x86_64 vDSO. I can't find anything that depends on this magic offset, or that should care at all about the particular location of of the .data section (all from vvar.c) in the vDSO image. If it is really desireable to place .data at 0x900, then it should be after all the other sections so they fill in the space up to 0x900. This removes the 0x900 magic and cleans up the output sections generally in the vDSO linker script. This saves a few hundred bytes in the size of the vDSO file, bringing it back well under 4kb total so that its vma only needs one page.

| * x86: expand /proc/interrupts to include missing vectors, v2Joe Korty2007-10-1711-4/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add missing IRQs and IRQ descriptions to /proc/interrupts. /proc/interrupts is most useful when it displays every IRQ vector in use by the system, not just those somebody thought would be interesting. This patch inserts the following vector displays to the i386 and x86_64 platforms, as appropriate: rescheduling interrupts TLB flush interrupts function call interrupts thermal event interrupts threshold interrupts spurious interrupts A threshold interrupt occurs when ECC memory correction is occuring at too high a frequency. Thresholds are used by the ECC hardware as occasional ECC failures are part of normal operation, but long sequences of ECC failures usually indicate a memory chip that is about to fail. Thermal event interrupts occur when a temperature threshold has been exceeded for some CPU chip. IIRC, a thermal interrupt is also generated when the temperature drops back to a normal level. A spurious interrupt is an interrupt that was raised then lowered by the device before it could be fully processed by the APIC. Hence the apic sees the interrupt but does not know what device it came from. For this case the APIC hardware will assume a vector of 0xff. Rescheduling, call, and TLB flush interrupts are sent from one CPU to another per the needs of the OS. Typically, their statistics would be used to discover if an interrupt flood of the given type has been occuring. AK: merged v2 and v4 which had some more tweaks AK: replace Local interrupts with Local timer interrupts AK: Fixed description of interrupt types.

Not only will most (99%?) of the systems not use all the slots in these arrays, particularly when NR_CPUS is increased to accommodate future very high cpu count systems, but a number of cache lines are passed unnecessarily on the system bus when these arrays are referenced by cpus on other nodes. Typically, the values in these arrays are referenced by the cpu accessing it's own values, though when passing IPI interrupts, the cpu does access the data relevant to the targeted cpu/node. Of course, if the referencing cpu is not on node 0, then the reference will still require cross node exchanges of cache lines. A common use of this is for an interrupt service routine to pass the interrupt to other cpus local to that node. Ideally, all the elements in these arrays should be moved to the per_cpu data area. In some cases (such as x86_cpu_to_apicid) the array is referenced before the per_cpu data areas are setup. In this case, a static array is declared in the __initdata area and initialized by the booting cpu (BSP). The values are then moved to the per_cpu area after it is initialized and the original static array is freed with the rest of the __initdata. This patch: Fix four instances where cpu_to_node is referenced by array instead of via the cpu_to_node macro. This is preparation to moving it to the per_cpu data area.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the x86_cpu_to_log_apicid array. It is set in arch/x86_64/kernel/genapic_flat.c:flat_init_apic_ldr() and arch/x86_64/kernel/smpboot.c:do_boot_cpu() but it is never referenced.

| * i386: Remove strrchr assembler implementationAndi Kleen2007-10-171-20/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The constraints in the inline assembler implementation of i386 strrchr() were incorrect and break the build with recent gcc 4.3. Since there are only very few callers of strrchr() and none of them are performance relevant just remove the assembler implementation and use the C fallback instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create an inline function for clflush(), with the proper arguments, and use it instead of hard-coding the instruction.
