* x86: Fix section mismatches in mpparseRakib Mullick2009-04-12
| | | | | | | | | | | | | | Impact: fix section mismatch In arch/x86/kernel/mpparse.c, smp_reserve_bootmem() has been called and also refers to a function which is in .init section. Thus causes the first warning. And check_irq_src() also requires an __init, because it refers to an .init section.

* x86: mpparse: clean up code by introducing a few helper functionsJaswinder Singh Rajput2009-03-18
| | | | | | | | | | | | | | | | | | | | Impact: cleanup Refactor the MP-table parsing code via the introduction of the following helper functions: skip_entry() smp_reserve_bootmem() check_irq_src() check_slot() To simplify the code flow and to reduce the size of the following oversized functions: smp_read_mpc(), smp_scan_config().

* x86: check mptable physptr with max_low_pfn on 32bitYinghai Lu2009-02-23
| | | | | | | | | | | | | | | | | | | | | Impact: fix early crash on LinuxBIOS systems Kevin O'Connor reported that Coreboot aka LinuxBIOS tries to put mptable somewhere very high, well above max_low_pfn (below which BIOSes generally put the mptable), causing a panic. The BIOS will probably be changed to be compatible with older Linus versions, but nevertheless the MP-spec does not forbid an MP-table in arbitrary system RAM, so make sure it all works even if the table is in an unexpected place.

Interrupt-remapping must be enabled before enabling x2apic, this is needed to ensure that IO interrupts continue to work properly after the cpu mode is changed to x2apic(which uses 32bit extended physical/cluster apic id). On systems where apicid's are > 255, BIOS can handover the control to OS in x2apic mode. Or if the OS handover was in legacy xapic mode, check if it is capable of x2apic mode. And if we succeed in enabling Interrupt-remapping, then we can enable x2apic mode in the CPU.
