2008-08-17x86: apic - unify clear_local_APICCyrill Gorcunov
- Remove redundant masking of APIC_LVTTHMR register in apic_32.c - Add masking of APIC_LVTTHMR register to apic_64.c. We use a bit complicated #ifdef here: CONFIG_X86_MCE_P4THERMAL is 32bit specific and X86_MCE_INTEL is 64bit specific so the appropriate config variable will be set by Kconfig. - the APIC_ESR register clearing in apic_64.c now uses not straightforward way but this is allowed tradeoff.

2008-08-15x86: apic - unify __setup_APIC_LVTTCyrill Gorcunov
To be able to unify this function we RE-introduce APIC_DIVISOR for 64bit mode. This snipped was eliminated in some time ago in a sake of clenup but now we need it again since it allow up to get rid of #ifdef(s). And lapic_is_integrated call is added in apic_64.c but since we always have APIC integrated on 64bit cpu compiler will ignore this call.

2008-08-14x86: resurrect proper handling of maxcpus= kernel option (v2)Max Krasnyansky
For some reason we had two parsers registered for maxcpus=. One in init/main.c and another in arch/x86/smpboot.c. So I nuked the one in arch/x86. Also 64-bit kernels used to handle maxcpus= as documented in Documentation/cpu-hotplug.txt. CPUs with 'id > maxcpus' are initialized but not booted. 32-bit version for some reason ignored them even though all the infrastructure for booting them later is there. In the current mainline both 64 and 32 bit versions are broken. This patch restores the correct behaviour. I've tested x86_64 version on 4- and 8- way Core2 and 2-way Opteron based machines. Various config combinations SMP, !SMP, CPU_HOTPLUG, !CPU_HOTPLUG. Booted with maxcpus=1 and maxcpus=4, etc. Everything is working as expected. So far we've received two reports from different people confirming that 32-bit version also works fine, both on dual core laptops and 16way server machines. [v2: This version fixes visws breakage pointed out by Ingo.] Signed-off-by: Max Krasnyansky <maxk@qualcomm.com> Cc: lizf@cn.fujitsu.com Cc: jeff.chua.linux@gmail.com Signed-off-by: Ingo Molnar <mingo@elte.hu>
