Fix rebuild of kernel when there is no changes. This happened for i386. Using make V=2 hinted that the output files were not assigned to targets - fixed by this patch.

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.

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.

Typically the oops first lines look like this: BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000 printing eip: c049dfbd *pde = 00000000 Oops: 0002 [#1] PREEMPT SMP ... Such output is gained with some ugly if (!nl) printk("\n"); code and besides being a waste of lines, this is also annoying to read. The following output looks better (and it is how it looks on x86_64): BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000 printing eip: c049dfbd *pde = 00000000 Oops: 0002 [#1] PREEMPT SMP ...

Call cache_add_dev() from cache_sysfs_init() explicitly, instead of referencing the CPU notifier callback directly from generic startup code. Looks cleaner (to me at least) this way, and also makes it possible to use other tricks to replace __cpuinit{data} annotations, as recently discussed on this list.
