The following commit has been merged into the x86/irq branch of tip: Commit-ID: f1b7d45d3f8f3e18e190e71cb54d4b1917300d1d Gitweb: https://git.kernel.org/tip/f1b7d45d3f8f3e18e190e71cb54d4b1917300d1d Author: H. Peter Anvin (Intel) <hpa@xxxxxxxxx> AuthorDate: Wed, 19 May 2021 14:21:49 -07:00 Committer: Thomas Gleixner <tglx@xxxxxxxxxxxxx> CommitterDate: Fri, 21 May 2021 12:36:44 +02:00 x86/irq: Remove unused vectors defines UV_BAU_MESSAGE is defined but not used anywhere in the kernel. Presumably this is a stale vector number that can be reclaimed. MCE_VECTOR is not an actual vector: #MC is an exception, not an interrupt vector, and as such is correctly described as X86_TRAP_MC. MCE_VECTOR is not used anywhere is the kernel. Note that NMI_VECTOR *is* used; specifically it is the vector number programmed into the APIC LVT when an NMI interrupt is configured. At the moment it is always numerically identical to X86_TRAP_NMI, that is not necessarily going to be the case indefinitely. Signed-off-by: H.
