Use the APIC to determine the hardware processor id - x86_64

2007-05-09T19:30:48+00:00

hard_smp_processor_id used to be just a macro that hard-coded hard_smp_processor_id to 0 in the non SMP case. When booting non SMP kernels on hardware where the boot ioapic id is not 0 this turns out to be a problem. This is happens frequently in the case of kdump and once in a great while in the case of real hardware. Use the APIC to determine the hardware processor id in both UP and SMP kernels to fix this issue. Notice that hard_smp_processor_id is only used by SMP code or by code that works with apics so we do not need to handle the case when apics are not present and hard_smp_processor_id should never be called there.

Remove hardcoding of hard_smp_processor_id on UP systems

2007-05-09T19:30:48+00:00

With the advent of kdump, the assumption that the boot CPU when booting an UP kernel is always the CPU with a particular hardware ID (often 0) (usually referred to as BSP on some architectures) is not valid anymore. The reason being that the dump capture kernel boots on the crashed CPU (the CPU that invoked crash_kexec), which may be or may not be that particular CPU. Move definition of hard_smp_processor_id for the UP case to architecture-specific code ("asm/smp.h") where it belongs, so that each architecture can provide its own implementation.

[PATCH] x86: consolidate smp_send_stop()

2007-05-02T17:27:05+00:00

Synchronize i386's smp_send_stop() with x86-64's in only try-locking the call lock to prevent deadlocks when called from panic(). In both version, disable interrupts before clearing the CPU off the online map to eliminate races with IRQ handlers inspecting this map. Also in both versions, save/restore interrupts rather than disabling/ enabling them. On x86-64, eliminate one function used here by folding it into its single caller, convert to static, and rename for consistency with i386 (lkcd may like this).

[PATCH] x86: adjust inclusion of asm/fixmap.h

2007-05-02T17:27:04+00:00

Move inclusion of asm/fixmap.h to where it is really used rather than where it may have been used long ago (requires a few other adjustments to includes due to previous implicit dependencies). Signed-off-by: Jan Beulich Signed-off-by: Andi Kleen

To see these warnings run: scripts/mod/modpost arch/x86_64/kernel/built-in.o kbuild will be fixed but the 'noise-level' had to be decresed first. There remains a few section mismatch warnigns for x86_64 for areas where I did not feel confident. Signed-off-by: Sam Ravnborg Signed-off-by: Andi Kleen
