x86: PIC, L-APIC and I/O APIC debug information
Dump all the PIC, local APIC and I/O APIC information at the fs_initcall() level, which is after ACPI (if used) has initialised PCI information, making the point of invocation consistent across MP-table and ACPI platforms. Remove explicit calls to print_IO_APIC() from elsewhere. Make the interface of all the functions involved consistent between 32-bit and 64-bit versions and make them all static by default by the means of a New-and-Improved(TM) __apicdebuginit() macro. Note that like print_IO_APIC() all these only output anything if "apic=debug" has been passed to the kernel through the command line. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Cc: Chuck Ebbert <cebbert@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
