From f361798cdf8d107102278a976c34c3bc1fd816e9 Mon Sep 17 00:00:00 2001 From: "Charles E. Youse" Date: Mon, 30 Sep 2019 11:51:49 -0400 Subject: [PATCH] arch/x86: limit number of IRQ vectors to 224 Trivial change to the Kconfig: the first 32 vectors are reserved, so it's not possible to have 256 IRQ vectors. Change max to 224. Signed-off-by: Charles E.
