2008-10-16x86: apic - unify APIC_DIVISORCyrill Gorcunov
Use APIC_DIVISOR being set to 16 for both 32/64bit mode. To escape APIC timer underflow during calibration set it to the maximum possible value. Also typo error (CONFG instead of proper CONFIG) fixed. The error was caught by Venkatesh Pallipadi, thanks a lot Venkatesh!

2008-10-16x86: io-apic - interrupt remapping fixCyrill Gorcunov
Interrupt remapping could lead to NULL dereference in case of kzalloc failed and memory leak in other way. So fix the both cases. Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Cc: "Maciej W.

2008-10-16x86: apic - fix unused vars warning in calibrate_APIC_clockCyrill Gorcunov
If we don't have CONFIG_X86_PM_TIMER=y compiler warns about unused variables. Move PM timer based calibration into a separate function and make the code cleaner and the compiler happy as well. Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-10-16x86: apic - unify smp_spurious/error_interrupt declarationCyrill Gorcunov
According to entry_64.S we do pass pt_regs pointer into interrupt handlers but don't use them. So we safely may merge the declarations. Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-16x86: let 64 bit to use 32 bit calibrate_apic_clockYinghai Lu
Use the 32-bit APIC calibration code - it's more mature. Signed-of-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
