[PATCH 0/6] x86/irq: trap and interrupt cleanups

[H. Peter Anvin]

From: "H. Peter Anvin (Intel)" <hpa@xxxxxxxxx>

A collection of trap/interrupt-related patches, almost all
cleanups. The only patches that should have any possible effect at all
are:

4/6 - x86/irq: merge common code in DEFINE_IDTENTRY_SYSVEC[_SIMPLE]

	This patch reverses kvm_set_cpu_l1tf_flush_l1d() and
	__irq_enter_raw() in DEFINE_IDTENTRY_SYSVEC_SIMPLE() in order
	to be able to unify the code with DEFINE_IDTENTRY_SYSVEC().

	The reason for unification is mainly to avoid the possibility
	of inadvertent divergence rather than the rather modest amount
	of code.

5/6 - x86/irq: WARN_ONCE() if irq_move_cleanup is called on a pending interrupt

	This condition is believed to be impossible after many
	improvements to the IRQ vector allocation code since this
	function was written. Per discussion with tglx, add a
	WARN_ONCE() if this happens as a first step towards excising
	this hack.

--- 
    x86/traps: add X86_NR_HW_TRAPS to <asm/trapnr.h>
    x86/irqvector: add NR_EXTERNAL_VECTORS and NR_SYSTEM_VECTORS
    x86/idt: remove address argument to idt_invalidate()
    x86/irq: merge common code in DEFINE_IDTENTRY_SYSVEC[_SIMPLE]
    x86/irq: WARN_ONCE() if irq_move_cleanup is called on a pending interrupt
    x86/irq: remove unused vectors from <asm/irq_vectors.h>
