arch/x86/kernel/ is getting a bit crowded, and the APIC drivers are scattered into various different files. Move them to arch/x86/kernel/apic/*, and also remove the 'gen' prefix from those which had it. Also move APIC related functionality: the IO-APIC driver, the NMI and the IPI code.

Impact: cleanup Now that all APIC code is consolidated there's nothing 'gen' about apics anymore - so rename 'struct genapic' to 'struct apic'. This shortens the code and is nicer to read as well. Signed-off-by: Ingo Molnar <mingo@elte.hu>

These are cleanups that change the md5 signature: - asm/ => linux/ include conversion - simplify the code flow of find_unisys_acpi_oem_table() - move ACPI methods into one #ifdef block - remove 0/NULL initialization of statics - simplify/standardize printouts - update copyrights - more cleanups, pointed out by checkpatch arch/x86/kernel/es7000_32.o: text data bss dec hex filename 2693 192 44 2929 b71 es7000_32.o.before 2688 192 44 2924 b6c es7000_32.o.after Signed-off-by: Ingo Molnar <mingo@elte.hu>

Impact: cleanup In the subarch times there were a number of externs between various bits of the ES7000 code. Now that there's a single es7000-platform support file, the externs can be removed and the functions can be changed the statics. Beyond the cleanup factor, this also shrinks the size of the kernel image a bit: arch/x86/kernel/es7000_32.o: text data bss dec hex filename 2813 192 44 3049 be9 es7000_32.o.before 2693 192 44 2929 b71 es7000_32.o.after Signed-off-by: Ingo Molnar <mingo@elte.hu>

There were multiple definitions of apicid_cluster() scattered around in APIC drivers - but the definitions are equivalent to the already existing generic APIC_CLUSTER() method. So remove apicid_cluster() and change all users to APIC_CLUSTER().

Impact: cleanup Reduce the number of include files to worry about. Also, most of the users of APIC facilities had to include genapic.h already, which embedded apic.h, so the distinction was meaningless. [ include apic.h from genapic.h for compatibility. ] Signed-off-by: Ingo Molnar <mingo@elte.hu>

Impact: fix "garbled display, laptop is unusable" bug Commit e51a1ac2 ("x86, olpc: fix endian bug in openfirmware workaround") breaks model comparison on OLPC; the value 0xc2 needs to be scaled up by olpc_board(). The pre-patch version was wrong, but accidentally worked anyway (big-endian 0xc2 is big enough to satisfy all other board revisions, but little endian 0xc2 is not).
