\| *	x86: don't send an IPI to the empty set of CPU's	Linus Torvalds	2009-08-21	1	-0/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The default_send_IPI_mask_logical() function uses the "flat" APIC mode to send an IPI to a set of CPU's at once, but if that set happens to be empty, some older local APIC's will apparently be rather unhappy. So just warn if a caller gives us an empty mask, and ignore it. This fixes a regression in 2.6.30.x, due to commit 4595f9620 ("x86: change flush_tlb_others to take a const struct cpumask"), documented here: http://bugzilla.kernel.org/show_bug.cgi?id=13933 which causes a silent lock-up. It only seems to happen on PPro, P2, P3 and Athlon XP cores. Most developers sadly (or not so sadly, if you're a developer..) have more modern CPU's. Also, on x86-64 we don't use the flat APIC mode, so it would never trigger there even if the APIC didn't like sending an empty IPI mask.

*	x86, apic: move APIC drivers to arch/x86/kernel/apic/*	Ingo Molnar	2009-02-17	1	-0/+164
	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.
